Description

Technical Field

[0001] This invention relates to the field of plastic sheet processing and testing equipment, and in particular to an integrated device for conveying and testing plastic sheets. Background Technology

[0002] In current continuous production of plastic sheets, the sampling and testing of compressive strength still largely relies on traditional offline methods, which has become a key bottleneck restricting the intelligent upgrading of production lines. Specifically, the existing testing method first faces the problem of process fragmentation: because traditional pressure testing machines are independent of the production flow, the sheets must be manually removed from the conveyor line and transported to a dedicated testing area during testing. This cumbersome process disrupts the continuity of the production line, resulting in low overall flow efficiency. Secondly, this mode of testing is lagging: offline sampling inspection results in a significant delay in quality data feedback, making it impossible to monitor and trace data for each sheet in the production process in real time. This quality control method makes it difficult to detect minor drifts in production parameters in a timely manner, easily leading to the outflow of batches of defective products, significantly increasing rework and scrap costs. The equipment itself has limitations: traditional presses mostly use hydraulic or large servo loading structures, which are not only bulky and heavy, but also have harsh operating environment requirements, making them unsuitable for high-speed conveyor line layouts and difficult to achieve embedded integration and automated linkage of the equipment.

[0003] In conclusion, traditional testing methods are too cumbersome in terms of physical space, fragmented in terms of process flow, and slow in terms of data feedback, and can no longer meet the urgent needs of modern manufacturing for efficient, accurate, and full-process quality control. Summary of the Invention

Through integrated design, it realizes in-situ compressive strength testing of the sheets during the conveying process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plastic sheet conveying and testing integrated device includes a conveying assembly for conveying the plastic sheet and a testing assembly linked to the conveying assembly for testing the plastic sheet. The testing assembly includes multiple testing units mounted on a testing bracket. The main body of the testing bracket is configured as a mounting top plate. A data acquisition camera for testing the plastic sheet is mounted on one side of the mounting top plate, and a testing mounting plate for mounting the testing units is mounted on the lower surface of the mounting top plate. A laser rangefinder for detecting the thickness of the plastic sheet is mounted at the front end of the testing mounting plate, and a limiting pressure roller for pressing down the plastic sheet is mounted on the lower surface of the testing mounting plate. The main body of the testing unit is configured to connect a threaded cylinder and a pressure test plate, both of which are equipped with resistance strain gauge pressure sensors for detecting load. The detection mounting plate moves the detection unit up and down based on the data detected by the laser rangefinder, so that the limiting pressure roller presses down on the plastic plate conveyed by the conveying assembly, thereby keeping the lower surface of the pressure test plate at the same test distance from the upper surface of the plastic plates of different thicknesses.

[0006] As a preferred embodiment of the present invention: a test connecting plate is fixedly connected to the bottom end of the connecting threaded cylinder, a limiting connecting cylinder is fixedly connected to the upper surface of the pressure test plate, the resistance strain gauge pressure sensor is fixedly installed inside the limiting connecting cylinder, the test connecting plate presses on the top end of the resistance strain gauge pressure sensor, and is fixed inside the limiting connecting cylinder by a limiting pressure ring threaded onto the limiting connecting cylinder.

[0007] Based on the aforementioned scheme: an installation clamping sleeve is provided above the pressure plate of the compressive strength test. A limiting partition is integrally formed in the middle of the inner wall of the installation clamping sleeve. A guide connecting cylinder with an inner cavity that passes through the limiting partition is integrally formed in the middle of the lower surface of the limiting partition. The connecting threaded cylinder is slidably installed inside the guide connecting cylinder through a linear bearing.

[0008] Based on the aforementioned scheme: multiple stabilizing guide cylinders with internal cavities penetrating the limiting partition are equidistantly arranged on the lower surface of the limiting partition. A stabilizing guide rod is slidably installed inside the stabilizing guide cylinder through a linear bearing. The bottom end of the stabilizing guide rod is fixedly installed on the upper surface of the test connection plate.

[0009] Based on the aforementioned scheme: a motor bracket is fixedly installed on the upper surface of the limiting partition, a second servo motor is fixedly installed inside the motor bracket, an adjusting threaded rod is fixedly installed on the output shaft of the second servo motor, and the adjusting threaded rod is threadedly installed inside the connecting threaded cylinder.

[0010] As a preferred embodiment of the present invention: a plurality of mounting brackets are fixedly mounted on the lower surface of the detection mounting plate, and mounting bracket arms are fixedly mounted on both ends of the mounting brackets. A plurality of connecting shafts for mounting the limiting pressure rollers are rotatably mounted between the mounting bracket arms.

[0011] As a preferred embodiment of the present invention: lifting threaded columns are rotatably mounted on both sides of the mounting top plate, the top of the lifting threaded columns penetrates the mounting top plate and is connected to a servo motor through a gear pair, and a motor base is fixedly mounted on the upper surface of the mounting top plate, with two servo motors symmetrically mounted on the top of the motor base.

[0012] Based on the aforementioned scheme: the bottom end of the lifting threaded column is equipped with an installation base, and the top of both ends of the installation base is fixedly installed with guide slide columns, and the top of the guide slide columns is fixedly connected to the installation top plate.

[0013] Based on the aforementioned scheme: a lifting threaded cylinder is threadedly installed on the outer wall of the lifting threaded column, and a guide cylinder is sleeved on the outer wall of the guide slide column through a linear bearing. Both the guide cylinder and the lifting threaded cylinder are fixedly connected to the adjacent mounting bracket arm.

[0014] Based on the aforementioned scheme: a laser rangefinder II is fixedly installed at the top of the mounting base, and a reflector II is provided at the top of the laser rangefinder II. The reflector II is fixedly installed between the guide slide and the lifting threaded cylinder.

[0015] The beneficial effects of this invention are as follows: 1. This integrated conveying and testing device for plastic sheets effectively solves the problems of fragmented and inefficient traditional plastic sheet compression testing processes by deeply integrating the conveying and testing functions. It replaces the traditional bulky hydraulic press with a lightweight multi-point distributed testing unit, allowing the testing process to be directly embedded in the conveyor line. This enables online full inspection of plastic sheets while they are being conveyed, and the compression performance test can be completed without removing the sheets from the production line. This significantly improves testing efficiency and meets the needs of high-speed assembly line operations.

[0016] 2. This integrated conveying and testing device for plastic sheets breaks through the limitations of traditional offline sampling inspection. It can perform full testing on each produced sheet, monitor product quality in real time, fundamentally eliminate the risk of batch defective products flowing out, and significantly improve the quality consistency of outgoing products. At the same time, by setting a support structure in which the testing arm and the conveying bearing roller are coplanar, combined with a liftable limiting pressure roller, a stable and uniform rigid support and limit is formed on the tested sheet during testing, effectively eliminating the influence of conveying gaps on the accuracy of pressure testing and ensuring the accuracy of test data.

[0017] 3. This integrated plastic sheet conveying and inspection device utilizes laser ranging technology to automatically adapt to sheets of different thicknesses and specifications. Combined with a vision acquisition system, it continuously completes the judgment of multiple indicators at the same workstation. It not only achieves quantitative assessment of the compressive strength of the sheet, but also simultaneously identifies production defects on the sheet surface and irreversible deformation after pressure. Together with the automatic sorting mechanism at the back end, it forms a complete closed loop of inspection and screening, greatly reducing the intensity of manual intervention and improving the automation and intelligence level of the plastic sheet production line.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

During the conveying process of the plastic sheets, basic compressive strength and basic dimensional detection are performed on the plastic sheets to achieve full detection of the plastic sheets on the production line and ensure that the compressive strength and basic dimensions of the plastic sheets meet the processing requirements. The detailed mechanical properties of the plastic sheets need to be specially tested by sampling.

[0023] This device is equipped with a control module, such as an industrial computer, to control the operation of the overall device and to cooperate with the detection components to determine the detection results of the plastic sheet.

[0024] The main body of the conveying assembly 1 is a conveying base 101 fixedly installed on the ground. The conveying base 101 includes a base plate. Multiple supporting square columns are fixedly installed at equal intervals on both sides of the upper surface of the base plate. Mounting arms are fixedly installed at the top of the multiple supporting square columns on the same side. Multiple supporting crossbars are fixedly installed at equal intervals at the bottom between two mounting arms. Multiple conveying shafts 102 are rotatably installed at equal intervals at the top between two mounting arms. Conveying bearing rollers 103 for conveying plastic sheets are fixedly sleeved on the outer wall of the conveying shafts 102.

[0025] One end of the conveying shaft 102 is fixedly equipped with a synchronous wheel, and the outer walls of multiple synchronous wheels are clamped with synchronous belts. The other end of the conveying shaft 102, which is located at the material feeding end of the conveying assembly 1, is connected to a conveying motor through a sprocket and chain drive. With the cooperation of the synchronous belt and the synchronous wheel, multiple conveying shafts 102 drive the conveying bearing roller 103 to rotate at the same speed, so as to stably transmit the plastic sheet.

[0026] A frame base plate fixed to a support crossbar is provided in the middle between the two mounting arms. Multiple detection support arms 104 are integrally formed at equal intervals on the upper surface of the frame base plate. The detection support arms 104 are located between two adjacent conveyor bearing rollers 103. The upper part of both sides is set as an arc shape coaxial with the conveyor bearing roller 103, and the top surface of the detection support arm 104 is in the same plane as the horizontal sectional surface of the topmost point of the conveyor bearing roller 103.

[0027] The detection support arm 104 can be set up in conjunction with the conveyor bearing roller 103 to provide more comprehensive support for the plastic sheet, making it easier for the detection component to perform compressive strength testing on the plastic sheet. The conveyor motor is directly controlled by the industrial computer and operates intermittently. When the conveyor bearing roller 103 has completely conveyed the plastic sheet to the top of the multiple detection support arms 104, the conveyor motor is turned off, and the industrial computer starts the detection component to perform compressive strength testing on the plastic sheet.

[0028] The methods for determining the moving position of the plastic sheet include, but are not limited to, determination by position sensors and determination by conveying speed, which are all existing technologies and will not be described in detail in this application.

[0029] The top center of the detection support arm 104, which is closest to the feeding end of the conveying component 1, has an installation groove, and a reflector 105 is fixedly installed on the bottom wall of the installation groove.

[0030] The detection assembly includes multiple detection units 3 mounted on the detection bracket 2. The main body of the detection bracket 2 is a mounting top plate 201, which is located above multiple detection support arms 104.

[0031] The data acquisition camera 210 collects surface data of the plastic sheet on the conveying assembly 1 that has undergone compressive strength testing, and simultaneously collects the planar dimension information of the plastic sheet. The collected information is transmitted to the industrial computer. The industrial computer determines whether there are obvious defects on the surface of the plastic sheet and whether there are residual traces of the compressive strength test based on the collected image data. If so, it is a defective product; if not, it is a qualified product.

[0032] Lifting threaded columns 204 are rotatably mounted on the middle of both sides of the mounting plate 201. The top of the lifting threaded column 204 passes through the mounting plate 201 and is connected to a servo motor 203 through a gear pair. A motor base 202 is fixedly mounted on the upper surface of the mounting plate 201. Two servo motors 203 are symmetrically mounted on the top of the motor base 202. The servo motors 203 are directly controlled by an industrial computer, and the two servo motors 203 are linked to maintain synchronous output speed.

[0033] Two lifting threaded columns 204 are mounted on both sides of the conveying assembly 1, and the bottom end of the lifting threaded column 204 is rotatably mounted with the mounting base 205 through the bearing. The top of both ends of the mounting base 205 is fixedly mounted with guide slide columns 206, and the top of the guide slide columns 206 is fixedly connected to the mounting top plate 201.

[0034] The outer wall of the lifting threaded column 204 is threaded with a lifting threaded cylinder 212, and the outer wall of the guide slide column 206 is sleeved with a guide slide cylinder 213 through a linear bearing. The lifting threaded cylinder 212 and the guide slide cylinder 213 on the same side of the conveying assembly 1 are fixedly connected to the same mounting arm 214. Multiple connecting shafts 215 are rotatably installed between the two mounting arms 214. The outer wall of the connecting shafts 215 is fixedly installed with a limiting pressure roller 216 for pressing the plastic plate.

[0035] A second laser range finder 207 is fixedly mounted at the top end of the mounting base 205, a second reflector 211 is arranged at the top end of the second laser range finder 207, the second reflector 211 is fixedly mounted between the guide slide cylinder 213 and the lifting threaded cylinder 212, and the two cooperate to quickly measure the height of the mounting frame arms 214; the second laser range finder 207 feeds the measured data back to the industrial computer, and the industrial computer controls the output rotation speed of the two first servo motors 203 according to the measurement data of the two second laser range finders 203, so that the two mounting frame arms 214 are at the same horizontal height, ensuring the extrusion stability of the limit pressure roller 216 to the plastic plate.

[0037] A mounting base cylinder 219 is fixedly mounted on the upper surface of the front end of the detection mounting plate 218, a first laser range finder 220 is fixedly mounted inside the mounting base cylinder 219, and the first laser range finder 220 cooperates with the first reflector 105 to quickly measure the thickness of the plastic plate on the conveying assembly 1, and feed the detection data back to the industrial computer.

[0038] The distance from the upper surface of the first reflector 105 to the upper surface of the detection support arm 104 is fixed, the distance between the first laser range finder 220 and the first reflector 105 can be measured in real time, and the distance from the first laser range finder 220 to the upper surface of the plastic plate can be measured in real time. Through mathematical calculation, the industrial computer can quickly calculate the thickness of the plastic plate; at the same time, the distance from the first laser range finder 220 to the lowermost end of the limit pressure roller 216 is fixed, and the industrial computer can quickly calculate the displacement length of the limit pressure roller 216, so as to ensure the fixing effect of the limit pressure roller 216 on the plastic plate.

[0039] The main body of the detection unit 3 is provided with a connecting threaded cylinder 308 and a compression resistance test pressure plate 304, which are provided with a resistance strain type pressure sensor 313 for detecting load; the compression resistance test is performed on the upper surface of the plastic plate by using the compression resistance test pressure plate 304, and the force borne by the plastic plate during the compression resistance test process is measured by using the resistance strain type pressure sensor 313. When the industrial computer detects that the applied external force detected by the resistance strain type pressure sensor 313 reaches a specified value, the industrial computer stops the detection unit 3 from continuing to load the plastic plate and ends the current test, then the data acquisition camera 210 performs image data acquisition on the compression resistance test surface of the plastic plate, and then the industrial computer judges the compression resistance test result of the plastic plate to determine the quality of the plastic plate.

[0040] A test connecting plate 312 is fixedly connected to the bottom end of the connecting threaded cylinder 308. A limit connecting cylinder 303 is fixedly connected to the upper surface of the pressure test plate 304.

The test connecting plate 312 presses on the top of the resistance strain gauge pressure sensor 313 and is fixed inside the limit connecting cylinder 303 by a limit pressure ring that is threadedly installed on the limit connecting cylinder 303.

[0041] A mounting sleeve 301 is provided above the pressure plate 304 for the compression test. The mounting sleeve 301 is inserted into the positioning through groove. A limiting ring 302 is integrally formed in the middle of the outer wall of the mounting sleeve 301. Multiple inserts that are inserted into the upper surface of the test mounting plate 218 are integrally formed at equal intervals at the bottom end of the limiting ring 302. The inserts are fixed to the test mounting plate 218 by bolts.

[0042] A limiting partition is integrally formed in the middle of the inner wall of the mounting sleeve 301. A guide connecting sleeve 309 is integrally formed in the middle of the lower surface of the limiting partition. The inner cavity of the guide connecting sleeve 309 passes through the limiting partition, and the axis of the guide connecting sleeve 309 is collinear with the axis of the mounting sleeve 301. The connecting threaded sleeve 308 is slidably installed inside the guide connecting sleeve 309 through a linear bearing to ensure that the connecting threaded sleeve 308 can drive the pressure test plate 304 to move up and down stably.

[0043] Multiple stabilizing guide cylinders 310 are welded at equal intervals on the lower surface of the limiting partition. The inner cavity of the stabilizing guide cylinder 310 passes through the limiting partition, and a reinforcing rib is welded between the outer wall of the stabilizing guide cylinder 310 and the inner wall of the mounting sleeve 301.

[0044] The stable guide cylinder 310 has a stable guide rod 311 slidably installed inside via a linear bearing. The bottom end of the stable guide rod 311 is fixedly installed on the upper surface of the test connecting plate 312 and cooperates with the connecting threaded cylinder 308 to further enhance the stability of the pressure test plate 304.

[0045] A motor bracket 305 is fixedly installed on the upper surface of the limiting partition. A servo motor 306 is fixedly installed inside the motor bracket 305. An adjusting threaded rod 307 is fixedly installed on the output shaft of the servo motor 306. The adjusting threaded rod 307 is threaded inside the connecting threaded cylinder 308 to stably control the lifting and lowering of the connecting threaded cylinder 308. The servo motor 306 is directly controlled by an industrial computer. Multiple detection units 3 are linked together to synchronously perform the compression test on the plastic sheet, and the same load is applied to the plastic sheet. The lower surface of the compression test plate 304 and the upper surface of plastic sheets of different thicknesses are kept at the same test distance.

[0046] Example 1: Taking a conventional PVC rigid sheet with a thickness of 5 to 20 mm as an example, the PVC rigid sheet enters from the feed end of the conveying assembly 1. The industrial computer controls the conveying motor to drive the conveying bearing roller 103, transferring the PVC rigid sheet above the detection support arm 104. When the PVC rigid sheet covers the reflective sheet 105, the industrial computer quickly calculates the thickness of the PVC rigid sheet based on the data fed back by the laser rangefinder 220, and simultaneously determines the descent height of the detection mounting plate 218. It then drives two servo motors 203, and under the meshing transmission of the gear pair, the two lifting threaded cylinders 204 rotate synchronously, driving the two lifting threaded cylinders 212 to descend synchronously. With the cooperation of laser rangefinder 207 and reflector 211, the industrial computer accurately controls the descent height of the testing mounting plate 218, while ensuring that the limiting pressure roller 216 can stably press on the upper surface of the PVC rigid plate. With the cooperation of the limiting pressure roller 216, the conveying bearing roller 103 stably transfers the PVC rigid plate to the top of the testing support arm 104. Then, the industrial computer shuts down the conveying motor and simultaneously starts multiple testing units 3 on the testing mounting plate 218. The servo motor 306 drives the adjusting threaded rod 307 to rotate according to the parameters preset by the industrial computer. The adjusting threaded rod 307 drives the connecting threaded cylinder 308 to move the pressure test plate. 304 moves steadily downwards to apply load to the PVC rigid board. When the industrial computer detects that the applied load measured by the resistance strain gauge pressure sensor 313 has reached the preset value, it controls the servo motor 306 to stop loading and rotate in the reverse direction, retracting the pressure test plate 304 and maintaining the current height of the detection mounting plate 218. The conveyor motor is then restarted until the PVC rigid board leaves the range of the detection support arm 104. The industrial computer controls the detection mounting plate 218 to rise three to five millimeters to facilitate the entry of the next PVC rigid board into the detection range of the detection unit 3. The detection support arm 104, now outside its range, moves to the mounting cover. Below cylinder 209, an industrial computer controls a data acquisition camera 210 to acquire image data of the upper surface of the plastic sheet. Based on the image data, the industrial computer determines whether the test area of ​​the pressure test plate 304 has experienced irreversible deformation or damage. If so, the PVC rigid sheet is a defective product. Simultaneously, it checks whether there are any defects on the surface of the PVC rigid sheet that should not exist during the production process. If so, the PVC rigid sheet is a defective product. The two steps of judgment are parallel, and only products that meet the standards at the same time are qualified. When judging whether the PVC rigid sheet is qualified, the industrial computer simultaneously measures the horizontal dimensions of the PVC rigid sheet, that is, its length and width.

[0047] Example 2: Based on Example 1, since the data acquisition camera 210 can only collect data from the upper surface of the PVC rigid board, a camera that can only collect surface traces from the lower surface of the PVC rigid board can be added to the conveyor base 101 directly below the data acquisition camera 210 to further determine the surface quality of the PVC rigid board. Based on Example 1, if the lower surface of the PVC rigid board has defects that should not exist during the production process, then the PVC rigid board is a defective product. This step of judgment is parallel to the two steps of judgment in Example 1.

[0048] Example 3: Based on Examples 1 and 2, a sorting industrial robot directly controlled by an industrial computer is installed at the unloading end of the conveying component 1. The sorting industrial robot sorts qualified and unqualified PVC rigid sheets in a timely manner, which facilitates the assembly line inspection and screening of PVC rigid sheets, realizes full quantity inspection of PVC rigid sheets, and improves the quality of PVC rigid sheets leaving the factory.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
