Description

Technical Field

[0001] The invention relates to the technical field of a feeding system, in particular to an automatic measuring and marking device in a feeding system. Background Art

[0002] In modern industrial production, the feeding system is an important part of the production line, and its degree of automation directly affects the overall production efficiency and product quality. The existing feeding system is usually composed of a conveying mechanism, a material distribution mechanism, a detection device, and a marking device. The conveying mechanism is responsible for transporting materials from the storage area to the processing area, and the material distribution mechanism distributes the materials to different workstations according to production needs. The detection device is used to measure the size, shape and other parameters of the material to ensure that the material meets the production standards. The marking equipment is used to mark key data such as production information and batch number on the material for subsequent quality traceability and management. With the advent of the Industrial 4.0 era, intelligent manufacturing has become a new trend in industrial development. As an important part of intelligent manufacturing, the importance of automatic measurement and marking devices is becoming increasingly prominent.

[0003] Although the existing feeding system and its supporting equipment have achieved automated production to a certain extent, there are still many shortcomings, especially in the automatic measurement and marking process. The specific manifestations are as follows:

[0004] Since manual material sorting requires positive and negative stacking and sequence, logical errors are prone to occur. This error not only increases uncertainty in the production process, but may also cause confusion in the subsequent production process. In addition, if the material itself has no obvious characteristics, it will also be difficult to identify it in the later stages, making it impossible to perfectly bind the product production data to the order of the product itself, resulting in deviations in the traceability results.

[0005] Although laser marking has the advantages of high precision and high definition, its marking process takes a long time. On high-speed production lines, the speed of laser marking often cannot keep up with the feeding speed, resulting in reduced production efficiency.

[0006] Therefore, it is necessary to provide an automatic measuring and marking device in a feeding system to improve production efficiency and product quality and ensure the accuracy of data traceability. Summary of the invention

[0007] To achieve the above object, the present invention provides the following technical solutions: an automatic measuring and marking device in a feeding system, comprising a feeding area, a measuring component is provided on the feeding area, a plurality of marking streamline components are arranged beside the feeding area, a plurality of laser marking machines are distributed in each of the marking streamline components, and a confirmation scanning device is provided at the rear end of each of the marking streamline components;

[0008] A transverse guide rail is provided above the loading area and spans each marking streamline assembly, and a manipulator is slidably arranged in the transverse guide rail;

[0009] A positioning and scanning device is provided between the measuring component and the manipulator.

[0010] Further, preferably, the marking streamline assembly includes a conveyor belt, a plurality of gantries are distributed on the conveyor belt, and the laser marking machine is respectively arranged in each gantry.

[0013] Furthermore, as a preference, racks are fixed on both sides of the conveyor belt, gear driving devices are provided on both sides of a gantry at the front end, and a gantry at the rear end is fixed in a slide rail.

[0014] Further, as a preference, the measuring assembly comprises a fixed ring, four sliders are distributed at both ends of the fixed ring, and a roller is arranged at one end of each slider close to the center of the circle;

[0015] The inner wall of the fixing ring is provided with measuring sensors, including but not limited to a surface roughness sensor, a distance measuring sensor, and a visual defect sensor.

[0016] Further, as a preference, both the front and rear end surfaces of the fixed ring are rotatably provided with swivels, and the slider is slidably provided in the swivel along the fixed ring;

[0017] An adjusting screw is rotatably arranged in a rotating ring on the back of the slider, and the adjusting screw is threadedly connected with the slider.

[0018] Further, as a preference, a telescopic block is slidably arranged in the slider, and the roller is arranged at the end of the telescopic block;

[0019] A spring is arranged between the sliding block and the telescopic block.

[0020] Further, preferably, the roller shaft located below is connected to a servo motor.

[0021] Furthermore, as a preference, the outer wall of the rotating ring is provided with a tooth groove, a worm is rotatably arranged under the fixed ring, the worm is connected to a driving motor, and the worm is meshed with the tooth groove of the outer wall of the rotating ring. Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the present invention, the automatic measurement and marking device realizes a fully automated process from plate loading, measurement, positioning and scanning to automatic marking through an integrated design. It greatly reduces manual intervention and improves the overall operating efficiency of the production line. At the same time, automated operation reduces human errors and improves product consistency and quality stability.

[0023] In the present invention, the measuring assembly adopts a design combining a fixed ring and a roller shaft, and the screw and the telescopic block are adjusted to ensure that the roller shaft can fit closely to the four sides of the plate, thereby realizing accurate measurement of the plate size, surface roughness and appearance defects. In addition, the rotating ring is driven by a driving motor to rotate, so that the plate can rotate in all directions during the measurement process, ensuring that the measuring sensor can accurately obtain data on each side of the plate, further improving the comprehensiveness and accuracy of the measurement.

[0024] In the present invention, the gantry design in the marking streamline assembly has a high degree of flexibility. By sliding the gantry on the slide rail and connecting the connecting rod, the distribution position of the laser marking machine can be conveniently adjusted to adapt to plates of different lengths and widths. This not only improves the versatility of the equipment, but also reduces the adjustment time and cost when changing production batches.

[0025] In the present invention, each marking streamline assembly is equipped with multiple laser marking machines, which can mark multiple plates at the same time, and the product QR code of each plate can be disassembled into multiple parts and marked by multiple laser marking machines respectively, which significantly shortens the marking time of a single plate and ensures that the running speed of the conveyor belt can keep up with the feeding speed. At the same time, the quality of the finished product is checked by confirming the scanning device to ensure that the QR code is printed clearly and accurately, ensuring the traceability of the product.

[0032] See also Figure 1 and Figure 2 In an embodiment of the present invention, an automatic measuring and marking device in a feeding system includes a feeding area 1, a measuring component 2 is provided on the feeding area 1, a plurality of marking streamline components 6 are arranged beside the feeding area 1, a plurality of laser marking machines 63 are distributed in each of the marking streamline components 6, and a confirmation scanning device 7 is provided at the rear end of each of the marking streamline components 6;

[0033] A transverse guide rail 4 is provided above the loading area 1 and spans across each marking streamline assembly 6, and a manipulator 5 is slidably provided in the transverse guide rail 4;

[0034] A positioning and scanning device 3 is provided between the measuring component 2 and the manipulator 5 .

[0035] When processing long strips of board material, a QR code is placed at the front end of the long strip of board material when sizing. After fine sawing into multiple sections, the sections are placed in the measuring component 2 for measurement in turn, and the robot 5 distributes the measured boards to each marking streamline component 6. The final product QR code is generated in sequence through the collected sizing QR codes and marked by multiple laser marking machines 63 respectively, and bound to the cut boards.

[0036] See also Figure 3 In this embodiment, the marking streamline assembly 6 includes a conveyor belt 61 , a plurality of gantries 62 are distributed on the conveyor belt 61 , and the laser marking machine 63 is respectively arranged in each gantry 62 .

[0037] In this embodiment, slide rails 64 are provided on both sides of the conveyor belt 61 , and each of the gantry frames 62 is slidably disposed on the slide rails 64 .

[0038] The distribution position of the laser marking machine 63 can be changed by sliding the gantry 62 to adapt to panels of different specifications.

[0039] In this embodiment, two connecting rods 65 distributed in an X shape are hinged on both sides of each gantry 62, and the ends of adjacent connecting rods 65 are also hinged together.

[0040] That is to say, two adjacent gantries 62 are hinged together through two connecting rods 65, so that the distance between the two adjacent gantries 62 is always kept consistent, ensuring that each marking streamline assembly 6 can mark panels of the same specification.

[0041] In this embodiment, racks 66 are fixed on both sides of the conveyor belt 61 , gear driving devices 67 are provided on both sides of a gantry 62 at the front end, and a gantry 62 at the rear end is fixed in a slide rail 64 .

[0042] The frontmost gantry 62 can be driven to slide along the rack 66 through the gear drive device 67, and under the action of the connecting rod 65, the spacing between each gantry 62 is changed synchronously, so as to adapt to plates of different lengths and ensure that the laser marking machine 63 can mark the specified position of plates of different lengths.

[0043] See also Figure 4 In this embodiment, the measuring assembly 2 includes a fixed ring 21, and four sliders 22 are distributed at both ends of the fixed ring 21. A roller 23 is provided at one end of each slider 22 close to the center of the circle;

[0044] The inner wall of the fixing ring 21 is provided with measuring sensors, including but not limited to a surface roughness sensor, a distance measuring sensor, and a visual defect sensor.

[0045] In this embodiment, a rotating ring 27 is rotatably provided on the front and rear end surfaces of the fixing ring 21 , and the sliding block 22 is slidably provided in the rotating ring 27 along the fixing ring 21 .

[0046] An adjusting screw 26 is rotatably disposed in a rotating ring 27 on the back of the slider 22 , and the adjusting screw 26 is threadedly connected to the slider 22 .

[0047] The sliding position of the slider 22 can be changed by rotating the adjusting screw 26, so that the roller 23 can fit the four sides around the plate.

[0048] In this embodiment, a telescopic block 24 is slidably disposed in the slider 22 , the roller shaft 23 is disposed at the end of the telescopic block 24 , and a spring 25 is disposed between the slider 22 and the telescopic block 24 .

[0049] The roller shaft 23 can be elastically fitted to the four sides around the plate by means of the telescopic block 24 and the spring 25 .

[0050] In this embodiment, the roller shaft 23 located at the bottom is connected to a servo motor 28 .

[0051] The servo motor 28 can drive the roller shaft 23 below to rotate, thereby driving the plate attached thereto to slide forward and backward.

[0052] See also Figure 5 In this embodiment, a tooth groove is provided on the outer wall of the rotating ring 27 , and a worm 29 is rotatably provided below the fixed ring 21 . The worm 29 is connected to the driving motor 210 , and the worm 29 meshes with the tooth groove on the outer wall of the rotating ring 27 .

[0053] By driving the worm 29 to rotate through the driving motor 210, the rotating ring 27 can be rotated, thereby rotating the plate clamped between the rollers 23, to ensure that the measuring sensors distributed on the inner wall of the fixed ring 21 can accurately measure the distance of each side of the plate, and can turn over the plate with the fixed-size QR code on the back to ensure that the fixed-size QR code is on the front.

[0054] In the specific implementation, a fixed-size QR code is pasted on the front end of the long strip of board, and after fine sawing, it is placed in the loading area in order to prepare for measurement and marking, which specifically includes the following steps:

[0055] By adjusting the screw 26, the roller 23 can fit the four sides of the plate to ensure that the plate is stable and centered;

[0056] The operator places the cut plates one by one in the fixing ring 21 of the measuring assembly 2;

[0057] The servo motor 28 drives the lower roller 23 to rotate, driving the plate to slide back and forth in the fixed ring 21. At the same time, the measuring sensor on the inner wall of the fixed ring 21 starts to work, comprehensively inspecting the surface roughness, size, appearance defects, etc. of the plate, and transmitting the data to the control system;

[0058] During the measurement process, the rotating ring 27 and the internal roller 23 are driven to rotate by the driving motor 210, so that the clamped plate also rotates, ensuring that the measuring sensors distributed on the inner wall of the fixed ring can accurately measure the distance of each side of the plate. If the fixed-size QR code is on the back of the plate, it can be turned to the front by rotating it, which is convenient for subsequent code scanning operations;

[0059] When the plate passes through the measuring component 2, the positioning and scanning device 3 automatically scans the fixed-size QR code on the front end of the plate, reads and saves the relevant size information, and prepares for subsequent marking;

[0060] According to the control system instruction, the manipulator 5 grabs the measured plate from the measuring component 2 and accurately distributes it to the corresponding marking streamline component 6;

[0061] Each marking streamline assembly 6 is pre-set according to the plate size and processing requirements, and the gantry 62 can adjust the spacing synchronously through the gear drive device 67 and the connecting rod 65 according to the length of the plate to ensure the accuracy of the marking position;

[0062] After the plate enters the marking streamline assembly 6, it is driven forward by the conveyor belt 61, and the laser marking machine 63 generates the final product QR code in sequence according to the collected fixed-size QR code information, and marks the plate through the laser marking machine 63 in the gantry 62;

[0063] The final product QR code is decomposed into multiple parts, which are marked separately by multiple laser marking machines 63 of the same marking streamline assembly 6, thereby reducing the residence time of the plate and increasing the running speed of the conveyor belt 61;

[0064] After the marking is completed, the scanning device 7 performs a quality check on the finished product to confirm that the two-dimensional code printing can be read clearly and accurately.

[0065] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
