Description

Technical Field

[0001] This invention relates to the field of sheet metal processing, specifically to an automated sheet metal production line and production method. Background Technology

[0002] Currently, sheet metal processing, such as cutting and bending, is basically done by a single machine. It relies entirely on manual operation for loading and unloading, manual control of the laser cutting machine, and manual sorting after cutting. The cut sheets are then fed into the bending machine for bending. The flow between processing steps is heavily dependent on manual labor, which leads to unstable production capacity and increases labor costs. If different sheets need to be processed, manual replacement of the sheets is required, which is not conducive to large-scale processing needs.

[0003] In addition, it was found that the existing bending process does not have a related positioning and stacking mechanism, which causes the sheet material to shift, resulting in inaccurate products after bending and failing to guarantee the consistency of product processing.

[0004] Based on this, the present invention proposes an automated production line and production method for sheet metal. Summary of the Invention

This effectively improves the automation level and processing efficiency of the sheet metal processing, and greatly reduces manual intervention and labor costs. The sheet metal is transferred to the tracked cutting and marking mechanism by the automatic feeding mechanism for marking before cutting. Then, the cut sheet metal is centered and stacked by the automatic material suction and stacking mechanism, which improves the processing accuracy of the sheet metal in the subsequent bending process. The sheet metal is then sent to the automatic bending mechanism by the automatic lifting and feeding mechanism for bending both sides of the cut sheet metal. Finally, the sheet metal is sent to the unloading rack for discharge by the automatic material suction and stacking mechanism.

[0018] On the other hand, the present invention also provides an automated sheet metal production method, which uses the above-mentioned automated sheet metal production line for processing, the method comprising the following steps:

[0019] S1. Preparations

[0020] Technicians generate part processing programs through host computer software and upload them to the part database. The automatic feeding mechanism, crawler-type cutting and marking mechanism, automatic material suction and stacking mechanism, automatic lifting and feeding mechanism, and automatic bending mechanism automatically obtain their processing data from the part programs. The part database contains information data on different sheet materials and sets the sheet material suction cup matching program. This program can correctly open the suction cups covering the sheet material and disable the suction cups covering the sheet material, and set the cutting and bending processes for different sheet materials.

[0021] S2, feeding, coding, cutting

[0022] The automatic feeding mechanism picks up and transfers the sheet material from storage rack A or storage rack B to the track conveyor of the track cutting and marking mechanism. According to the current sheet material processing requirements, the laser marking machine of the track cutting and marking mechanism marks the sheet material. After the QR code is printed, the sheet material is cut by the laser cutting machine according to the cutting process set by the system. The cut sheet material is then conveyed by the track conveyor.

[0023] S3, feeding, positioning and alignment, and packing.

[0024] The laser cutting machine sends feedback on the completion of the cutting to the control system. The control system then controls the automatic material feeding and stacking mechanism to move above the conveyor belt. The automatic material feeding and stacking mechanism's scanning camera quickly takes a picture and recognizes the QR code to read the database information set for the current sheet material. After comparing and filtering the sheet material names in the database, the system finds the program information that matches the sheet material name and loads it into the controller of the suction cup mechanism. The suction cup mechanism selects the corresponding suction cup matching program based on the recognized sheet material name and transfers the cut sheet material to the worktable through the matched vacuum suction cup. Then, the positioning and stacking mechanism positions, centers, and straightens the cut sheet material.

[0025] S4. Feeding, bending, unloading

[0026] After the alignment is completed, the suction cup mechanism is closed, and the pressure plate mechanism is opened. The pressure plate of the pressure plate mechanism presses the aligned sheet material onto the reversing suction cup of the automatic lifting and feeding mechanism, and at the same time, the reversing suction cup is opened, so that the sheet material is well attracted by the reversing suction cup. Then, the feeding motor of the automatic lifting and feeding mechanism sends the sheet material to the automatic bending mechanism for bending according to the set bending process. After one side is bent, the feeding motor of the automatic lifting and feeding mechanism returns along the same path, and the reversing motor is opened to rotate the reversing suction cup 180 degrees to complete the reversal of the sheet material. Then, the feeding motor sends the sheet material to the bending mechanism to complete the bending of the other side. Finally, the bending of both sides of the sheet material is completed. Then, the feeding motor returns along the same path to send the bent sheet material to the bottom of the suction cup mechanism. Finally, the suction cup mechanism sends the sheet material to the unloading rack for discharge.

[0027] The beneficial effects of this invention are:

[0028] 1. The automatic sheet metal production line of the present invention integrates an automatic feeding mechanism, a crawler-type cutting and marking mechanism, an automatic material suction and stacking mechanism, an automatic lifting and feeding mechanism, and an automatic bending mechanism into one production line, and controls them through the same control system. This effectively improves the automation level and processing efficiency in the sheet metal processing process, greatly reduces manual intervention and labor costs, and ensures the consistency of sheet metal processing and product quality.

[0029] Specifically, the automatic sheet metal production method of the present invention transfers the sheet metal to a tracked cutting and coding mechanism via an automatic feeding mechanism for pre-coding and cutting. Then, an automatic material suction and stacking mechanism centers and aligns the cut sheet metal, improving the processing accuracy of the sheet metal during subsequent bending. An automatic lifting and feeding mechanism then delivers the sheet metal to an automatic bending mechanism for bending both sides of the cut sheet metal. Finally, the automatic material suction and stacking mechanism delivers the sheet metal to the unloading rack for discharge. Furthermore, the automatic material suction and stacking mechanism includes a barcode scanning camera, capable of recognizing the pre-cut coding and automatically adjusting the working quantity of the vacuum suction cups. The bending mechanism performs bending according to a preset sheet metal bending program, achieving full automation and improving bending efficiency as well as the sorting efficiency of different sheet metals.

[0030] 2. The structural design of the automatic material feeding and stacking mechanism of the present invention enables automatic loading and unloading of sheet metal. By scanning the barcode with a barcode scanning camera, the code on the sheet metal is automatically identified, preparing for the subsequent sorting and bending processes by loading the corresponding program. Specifically, the suction cup mechanism can quickly adjust the activation scheme of the number of suction cups according to the identified sheet metal information, accurately grasping different parts; the automatic bending mechanism can load the corresponding program task according to the result of the camera scanning to complete the automated bending work. In addition, before bending, the design of the positioning and stacking mechanism can position and straighten the sheet metal, making the sheet metal centered and not offset, improving the subsequent sheet metal bending accuracy and efficiency, and improving product quality.

[0031] 3. Under the action of the positioning and stacking mechanism, the platen mechanism of the present invention ensures that the plate is not offset in the center position. In cooperation with the automatic lifting and feeding mechanism, the plate is pressed onto the reversing suction cup of the automatic lifting and feeding mechanism, which improves the adsorption of the reversing suction cup and also improves the accuracy of the bending operation, avoiding the problem of plate offset during the bending process due to insufficient adsorption force.

[0032] 4. Through the design of the second drive mechanism, the present invention can simultaneously drive two positive and negative threaded screws to rotate, and simultaneously drive the position adjustment of the stacking block, which can meet the processing requirements of different sized plates and expand the processing range of different sized plates of the present invention.

[0033] 5. The worktable of the present invention is provided with a shock-absorbing brush plate, and the shock-absorbing brush plate is provided with a number of anti-wear balls, which can prevent the sheet material from directly contacting the worktable, reduce the wear on the sheet material, and improve the quality of the sheet material after processing; and the reversing suction cup here, in combination with the pressure plate, improves the adsorption of the sheet material. In addition, in this embodiment, the reversing suction cup adopts a structure that combines a mechanical suction cup and a rubber suction cup to meet the processing needs of sheet materials of different materials. Furthermore, the reversing suction cup is provided with a number of metal protrusions, which can provide friction to the sheet material during rotation, thereby avoiding deviation and better ensuring accuracy, and improving the stability of the sheet material during the reversing process.

[0034] 6. The automatic feeding mechanism of the present invention can realize the automatic feeding of sheet metal. The design of the AB interchangeable storage rack can realize the position switching of sheet metal A and sheet metal B at any time, thereby improving the processing requirements of different sheet metals.

[0035] 7. This invention, through the design of a tracked cutting and marking mechanism, enables the marking of sheet metal before cutting and achieves automated cutting. By integrating the design of the tracked conveyor mechanism and the laser cutting machine, cutting and transfer are integrated, effectively solving the problem of waste disposal after waste is broken up. Waste can be automatically transported to the waste collection box, improving the environmental quality of the workshop, reducing the manual waste collection process, and greatly improving the level of automation.

Detailed Implementation

[0045] The technical solutions in 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.

[0046] In one specific embodiment of the present invention, such as Figure 1-7 As shown, an automated sheet metal production line includes a control system and an automatic feeding mechanism 1, a tracked cutting and marking mechanism 2, an automatic material feeding and stacking mechanism 3, an automatic lifting and feeding mechanism 4, and an automatic bending mechanism 5, all controlled by the control system. Sheet metal 100 is transferred to the tracked cutting and marking mechanism 2 via the automatic feeding mechanism 1 for marking and then cutting. The cut sheet metal is then stacked and aligned by the automatic material feeding and stacking mechanism 3, and then sent to the automatic bending mechanism 5 via the automatic lifting and feeding mechanism 4 for bending both sides of the cut sheet metal. Finally, the sheet metal is sent to the unloading rack 6 for discharge via the automatic material feeding and stacking mechanism 3.

[0047] The automatic sheet metal production line of the present invention integrates an automatic feeding mechanism 1, a crawler-type cutting and marking mechanism 2, an automatic material suction and stacking mechanism 3, an automatic lifting and feeding mechanism 4, and an automatic bending mechanism 5 into one production line, all controlled by the same control system. This effectively improves the automation level and processing efficiency of the sheet metal processing, and greatly reduces manual intervention and labor costs. The sheet metal 100 is transferred by the automatic feeding mechanism 1 to the crawler-type cutting and marking mechanism 2 for marking before cutting, and then the cut sheet metal is centered and stacked by the automatic material suction and stacking mechanism 3. Afterwards, the processing accuracy of the sheet metal during subsequent bending is improved. The sheet metal is then fed to the automatic bending mechanism 5 via the automatic lifting and feeding mechanism 4 for bending both sides of the cut sheet metal. Finally, it is fed to the unloading rack 6 via the automatic suction and stacking mechanism 3 for discharge. In this embodiment, the automatic suction and stacking mechanism 3 includes a barcode scanning camera 37, which can identify the inkjet code before cutting and automatically adjust the working quantity of the vacuum suction cups of the suction cup mechanism. The bending mechanism performs bending according to the preset sheet metal bending program, achieving full automation and improving bending efficiency as well as the sorting efficiency of different sheet metals. Of course, this invention is equipped with a matching sheet metal information database. Before operation, technicians generate configuration programs for each mechanism using sorting software. After processing, the programs are pushed to the suction cup database via the network, adjusting the working quantity of the vacuum suction cups of the suction cup mechanism according to different sheet metals, thus improving the accuracy and flexibility of the suction cup mechanism operation.

[0048] like Figure 2-3As shown, the automatic material feeding and stacking mechanism 3 includes a frame 31, a lifting mechanism 32, a suction cup mechanism 33, a barcode scanning camera 37, and a positioning and stacking mechanism 34. A slide block 35 is slidably arranged on the frame 31. The lifting mechanism 32 has two sets and is installed side by side in the slide block 35. The lifting mechanism 32 is located above the suction cup mechanism and drives the suction cup mechanism 33 to rise and fall. The barcode scanning camera 37 is installed on the suction cup mechanism 33. The suction cup mechanism 33 includes a suction cup frame 331 and several vacuum suction cups 332 arranged on the suction cup frame 331.

[0049] Here, the QR code recognition camera 37 quickly identifies the QR code markings containing information on the surface of the sheet metal. Combined with the suction cup mechanism 33, it can quickly adjust the activation scheme of its own vacuum suction cups according to the recognized information, accurately grasp different parts, and adjust the adsorption force of each vacuum suction cup as needed, thereby adapting to sheets of different sizes and weights, improving the accuracy and flexibility of the suction cup mechanism operation.

[0050] The positioning and stacking mechanism 34 includes a positioning component 341 and a stacking component 342. The positioning component 341 includes a first positive and negative threaded screw 3411 and two centering positioning blocks 3412. The first positive and negative threaded screw 3411 is horizontally installed at the lower middle position of the suction cup frame 331 and its end is driven by a first driving mechanism 3413. The two centering positioning blocks 3412 are symmetrically installed on the first positive and negative threaded screw 3411. Specifically, through the design of the positioning component 341, it is possible to ensure that the sheet metal is kept in the correct position on the suction cup mechanism 33, thereby ensuring the accuracy and consistency of the sheet metal processing, preventing the sheet metal from moving or shifting during bending, and ensuring the quality and efficiency of sheet metal processing.

[0051] In this embodiment, the material stacking assembly 342 has two sets symmetrically mounted on the suction cup frame 331. The two sets of material stacking assemblies 342 are driven simultaneously by the second drive mechanism 343. Each set of material stacking assemblies 342 includes a second positive and negative threaded screw 3421 and two material stacking blocks 3422. The second positive and negative threaded screw 3421 is mounted above the suction cup frame 331 and is perpendicular to the first positive and negative threaded screw 3411. The two material stacking blocks 3422 are symmetrically mounted on the second positive and negative threaded screw 3421. Each material stacking block 3422 is inverted Z-shaped. Specifically, through the design of the material stacking assembly 342, the sheet metal can be stacked and aligned. The lower end of the material stacking block 3422 is used to hold the material, ensuring the efficiency of the bending process and the quality of the final sheet metal bending product.

[0052] The automatic material feeding and stacking mechanism 3 of this invention is designed to enable automatic loading and unloading of sheet metal. The cut sheet metal is transferred to the worktable 7 by the suction cup mechanism 33. The code on the sheet metal is automatically identified by the barcode scanning camera, which prepares the corresponding program for subsequent sorting and bending processes. Specifically, the information of the currently cut sheet metal is sent to the control system, and subsequent bending is performed according to the bending process preset in the control system. Before bending, the positioning and stacking mechanism 34 is designed to position and straighten the sheet metal, ensuring that the sheet metal is centered and does not deviate, thereby improving the bending accuracy and efficiency of the subsequent sheet metal and improving product quality.

[0053] In this embodiment, a pressure plate mechanism 36 is provided on the suction cup frame 331. The pressure plate mechanism 36 includes a pressure plate 361 and a pressure plate cylinder 362. There are two pressure plate cylinders 362, which are symmetrically arranged on the suction cup frame 331. The output end of each pressure plate cylinder 362 is connected to the pressure plate 361. The positive and negative thread screws 3411 are located inside the pressure plate 361. Here, under the action of the positioning and stacking mechanism 34, the centering position of the sheet material does not shift. Combined with the action of the pressure plate mechanism, it can cooperate with the automatic lifting and feeding mechanism 4 to press the sheet material onto the reversing suction cup 45 of the automatic lifting and feeding mechanism 4. This improves the adsorption of the reversing suction cup 45 and also improves the accuracy of the bending operation, avoiding the problem of the sheet material shifting during the bending process due to insufficient adsorption force.

[0054] In this embodiment, the second drive mechanism 343 includes a material-stacking motor 3431, a drive wheel 3432, a driven wheel 3433, and a conveyor belt 3434. The material-stacking motor 3431 is mounted on the suction cup frame 331 via a motor mounting base 3435. The output shaft of the material-stacking motor 3431 is connected to the drive wheel 3432. There are two driven wheels 3433, which are respectively sleeved on the positive and negative threaded screws 3421. The drive wheel 3432 and the two driven wheels 3433 are connected by the conveyor belt 3434. The two sides of the drive wheel 3432 are provided with auxiliary drive wheels 3435 for tensioning the conveyor belt 3434. Through the design of the second drive mechanism 343, the two positive and negative threaded screws 3421 can be driven to rotate simultaneously, and the position of the material-stacking block 3422 can be adjusted at the same time, which can meet the processing requirements of different sized plates and expand the processing range of different sized plates of the present invention.

[0055] In this embodiment, each positive and negative threaded screw 3421 has a slide rail 3423 on its inner side. The slide rail 3423 is mounted on the suction cup frame 331. Each stacking block 3422 is slidably mounted on the slide rail 3423 by the slider 3424. This design can ensure the stability of the stacking block during the movement process.

[0056] like Figure 4-6Below the pressure plate 361 is a worktable 7. An automatic bending mechanism 5 is located on one side of the worktable 7. The worktable 7 has a shock-absorbing brush plate 71 with several wear-resistant balls 72. The automatic lifting and feeding mechanism 4 includes a slide rail 41, a slider 42, a feeding motor 43, a reversing motor 44, and a reversing suction cup 45. A pair of slide rails 41 are symmetrically installed on the inner side of the worktable 7. The slider 42 is slidably mounted on the pair of slide rails 41. A gearbox 46 is located at the bottom of the slider 42. The feeding motor... 43 is installed at the bottom of gearbox 46, and its output shaft passes through gearbox 46 and is fitted with gear 47. Gear 47 meshes with rack 48, which is located inside slide rail 41. Reversing motor 44 is installed at the bottom of slider 42, and its output shaft passes through slider 42 and is connected to reversing suction cup 45. Here, when feeding motor 43 is turned on, it will drive gear 47 to rotate, thereby achieving linear reciprocating motion on rack. When reversing motor is turned on, it will drive reversing suction cup to rotate 360 ​​degrees, thereby realizing the reversing of sheet material to achieve the requirement of bending on both sides.

[0057] The worktable 7 of this invention is equipped with a shock-absorbing brush plate 71, and the shock-absorbing brush plate 71 is designed with a plurality of anti-wear balls 72, which can prevent the sheet material from directly contacting the worktable, reduce wear on the sheet material, and improve the quality of the sheet material after processing. In addition, the reversing suction cup 45, in combination with the pressure plate, improves the adsorption of the sheet material. Furthermore, in this embodiment, the reversing suction cup adopts a structure that combines a mechanical suction cup and a rubber suction cup to meet the processing needs of sheet materials of different materials. The reversing suction cup is equipped with a plurality of metal protrusions, which can provide friction to the sheet material during rotation, thereby avoiding deviation and better ensuring accuracy, and improving the stability of the sheet material during the reversing process.

[0058] like Figure 7The automatic feeding mechanism 1 is installed inside the workbench 7. Specifically, the automatic feeding mechanism 1 includes a frame 11, a base frame 12, an AB interchangeable storage rack 13, and a feeding suction cup 14. The frame 11 spans above the AB interchangeable storage rack 13 and the tracked cutting and marking mechanism 2. The AB interchangeable storage rack 13 includes an A storage rack 131 and a B storage rack 132. The A storage rack 131 and the B storage rack 132 are rotatably mounted on the base frame 12, and the height and width of the A storage rack 131 are smaller than the height and width of the B storage rack 132. The position of storage rack 132 is interchangeable. A slide block 15 is slidably arranged on the frame 11. A lifting mechanism 16 is installed inside the slide block 15. The lifting end of the lifting mechanism 16 is connected to the feeding suction cup 14. In this embodiment, the rolling arrangement can be that the bottom of storage rack 131 and storage rack 132 are equipped with rollers. Then, the existing chain transmission mechanism can be used to realize the rolling of storage rack 131 and storage rack 132 on the base frame 12, so as to realize the purpose of switching between A plate and B plate at any time, and improve the processing requirements of different plates.

[0060] In this embodiment, the tracked cutting and marking mechanism 2 includes a frame 21, a tracked conveyor 22, a laser cutter 23, and a laser marking machine 24. The tracked conveyor 22 is mounted on the frame 21. The frame 21 has two slide rails 25 on both sides, and a slide frame 26 is slidably mounted on the slide rails 25. A slide rail 27 is mounted on one side of the slide frame 26. The laser cutter 23 is slidably mounted on the slide rails 27. A telescopic cylinder 28 is mounted on the side wall of the laser cutter 23, and the telescopic end of the telescopic cylinder 28 is connected to the laser marking machine 24.

[0061] In this embodiment, the suction cup frame 331 includes a rectangular frame 3311 and several supports 3312 arranged side by side within the rectangular frame 3311.

[0062] On the other hand, the present invention also provides an automated sheet metal production method, which uses the above-mentioned automated sheet metal production line for processing, and the method includes the following steps:

[0063] S1. Preparations

[0064] Technicians generate part processing programs through host computer software and upload them to the part database. Automatic feeding mechanism 1, crawler-type cutting and marking mechanism 2, automatic material suction and stacking mechanism 3, automatic lifting and feeding mechanism 4, and automatic bending mechanism 5 automatically obtain their processing data from the part program. The part database contains information data on different sheet materials and sets the sheet material suction cup matching program. This program can correctly open the suction cups covering the sheet material and disable the suction cups covering the sheet material. It also sets the cutting and bending processes for different sheet materials.

[0065] S2, feeding, coding, cutting

[0066] The automatic feeding mechanism 1 picks up and transfers the sheet material from storage rack A 131 or storage rack B 132 to the track conveyor 22 of the track cutting and marking mechanism 2. According to the current sheet material processing requirements, the laser marking machine 24 of the track cutting and marking mechanism 2 marks the sheet material. After the QR code is printed, the sheet material is cut by the laser cutting machine 23 according to the cutting process set by the system. The cut sheet material is then conveyed by the track conveyor 22.

[0067] S3, feeding, positioning and alignment, and packing.

[0068] The laser cutting machine 23 sends feedback on the completion of the cutting to the control system. The control system controls the automatic material feeding and stacking mechanism 3 to move above the conveyor belt 22. The automatic material feeding and stacking mechanism 3 uses a barcode scanning camera 37 to quickly take a picture and recognize the QR code to read the database information set for the current sheet material. After comparing and filtering with the sheet material name in the database, the program information that matches the sheet material name is found and then loaded into the controller of the suction cup mechanism 33. The suction cup mechanism 33 selects the corresponding suction cup matching program according to the sheet material name recognized by the picture. The cut sheet material is transferred to the worktable 7 through the matching vacuum suction cup 332. Then, the positioning and stacking mechanism 34 positions, centers and stacks the cut sheet material.

[0069] S4. Feeding, bending, unloading

[0070] After the alignment is completed, the suction cup mechanism 33 is closed and the pressure plate mechanism 36 is opened. The pressure plate 361 of the pressure plate mechanism 36 presses the aligned sheet material onto the reversing suction cup of the automatic lifting and feeding mechanism 4, and at the same time, the reversing suction cup 45 is opened, so that the sheet material is well attracted by the reversing suction cup 45. Then, the feeding motor 43 of the automatic lifting and feeding mechanism 4 sends the sheet material to the automatic bending mechanism 5 for bending according to the set bending process. After one side is bent, the feeding motor 43 of the automatic lifting and feeding mechanism 4 returns to the original path, and the reversing motor 44 is opened to rotate the reversing suction cup 45 180 degrees to complete the reversal of the sheet material. Then, the feeding motor 43 sends the sheet material to the bending mechanism to complete the bending of the other side. Finally, the bending of both sides of the sheet material is completed. Then, the feeding motor 43 returns to the original path to send the bent sheet material to the bottom of the suction cup mechanism 33. Finally, the suction cup mechanism 33 sends the sheet material to the unloading rack 6 for discharge.

Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
