Description

Technical Field

[0001] The present invention relates to the technical field of measurement and detection equipment, and in particular to a tinplate warpage detection device. Background Art

[0002] The warping of tinplate products refers to the unevenness and bending of the iron sheet during the production and processing. Warping is divided into L warping and C warping. Different heights of C warping have different effects on downstream customers. The size of the warping value directly determines the grade of the product, so warping detection is particularly important.

[0003] At present, the method for measuring the warpage of a single tinplate is: make a relatively straight back plate, stick the sample on the back plate after sampling, so that the sample is in a natural drooping state, and use a steel ruler to measure the distance between the raised edge of the sample and the back plate. The measured value is the warpage height; this scheme requires two people to operate at the same time, one person presses the upper end of the sample with his hand to make the sample fit tightly against the back plate, and the other person uses a steel ruler to measure the warpage height. Due to the measurement error of the steel ruler itself and the deviation of the human estimated reading, the final value is not accurate, and the whole process involves multiple steps such as manual taking of the sample, manual sticking, manual positioning, manual measurement, manual reading and manual recording. The whole operation process is relatively cumbersome and complicated, prone to operational deviations and errors, and requires multiple people to operate, which is not conducive to the efficient measurement and testing.

[0004] Therefore, there is a need for a tinplate warpage detection device that is convenient and efficient, has low labor intensity during the detection process, requires a small number of people for detection, and has high accuracy of the results. Summary of the Invention

The shadow lamp 210 is a spotlight with a single light emission direction. It is tilted and shines on the raised part of the sample (near the through groove 140) so that the shadow of the sample is cast on the display film 160. The image shooting component 220 is a camera, which is used to take a picture of the shadow of the sample and then record the data, which is then verified with the measured distance information to avoid errors.

[0025] Preferably, a pin is positioned on the sliding adjustment plate 130 , and a plurality of pin holes matching the pin are positioned on the base carrier plate 100 . After the sliding adjustment plate 130 slides to the target position, it is fixed by the pin.

[0028] Furthermore, the distance measuring component carrier 151 is a hard bracket.

[0029] Preferably, the distance measuring component carrier 151 is a guide rail structure, and the length direction is the same as the width direction of the basic carrier 100; the distance measuring component 150 is slidably positioned on the distance measuring component carrier 151 to achieve multi-point ranging.

[0030] Furthermore, the distance measuring component 150 slides by manual toggling or by being driven by an electrical device (motor, electric telescopic rod).

[0031] Preferably, the display film 160 is removed, and the shadow is directly projected onto the front surface of the base carrier plate 100 .

[0032] Preferably, the display film 160 is removed, and the shadow is directly cast on the front surface of the basic carrier board 100; the area between the through slot 140 on the basic carrier board 100 and the bottom surface of the basic carrier board 100 is provided with a scale.

[0033] Preferably, the color of the developing sheet 160 is white and made of matte material.

[0034] Preferably, the horizontal magnet 110 and the vertical magnet 120 are both located inside the base carrier 100 .

[0040] When using the tinplate warpage detection device in this application: 1. First, adjust the position of the sliding adjustment plate 130 according to the size of the sample being measured, so that the bottom of the sample partially covers the through-slot 140 and blocks the detection head of the distance measurement assembly 150. (If you need to test samples of different specifications, the position of the sliding adjustment plate 130 must be adjusted to ensure that the bottom edge of the sample being measured is consistent with the bottom edge of the sample during the previous measurement to ensure effective and reliable results.) 2. Then place the base carrier plate 100 vertically; 3. Then, the template is positioned on the base carrier 100 by suction, so that it fits on the front of the base carrier 100 and covers part of the through-groove 140 , and ensures that the top of the template is in close contact with the bottom of the sliding adjustment plate 130 ; 4.

At the same time, the shadow lamp 210 is controlled to illuminate the sample at an angle so that its shadow is cast on the developing film 160. The image capturing component 220 is controlled to take a picture, obtain an image of the developing film 160, and record the degree of coverage of the shadow on the developing film 160.

[0041] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The invention solves the technical problems in the prior art of warpage detection of tinplate products, such as the complicated detection steps, the need for multiple people to participate, the proneness of deviations and errors in the results, and the poor accuracy of the results. The invention achieves the technical effects of convenient and efficient detection of tinplate warpage detection, low labor intensity in the detection process, small number of people required for detection, and high accuracy of the results.

[0042] Example 2

[0043] Considering that during the processing and manufacturing of tinplate products, a small number of samples need to be obtained for testing in order to know the quality of the products in this batch, but this process only requires a small number of samples for testing. If non-contact image detection and laser scanning detection are used, the overall cost performance is poor due to the high cost, difficulty in equipment maintenance and high technical threshold. In addition, the installation and commissioning costs of non-contact image detection and laser scanning detection equipment are high, and the flexibility is poor after the arrangement. Especially for small and medium-sized production lines and small and medium-sized batches of products, the use of non-contact image detection and laser scanning detection methods will greatly increase production costs. The use of manual inspection after sampling will increase production costs. Although the method can also meet the requirements, it is less efficient, requires manual participation, and has a low degree of automation. Therefore, in order to solve the above problems, the embodiment of the present application optimizes and improves the structure of the tinplate warpage detection device on the basis of the above embodiment, and integrates it on the conveyor belt 001 for transporting the finished tinplate products (i.e., on the production line), so as to realize non-stop low-cost automatic sampling and detection. On the basis of the above embodiment, the present application adds a plate carrier 300, a rotating column 310, a rod carrier 400, a sheet discharge slide 500 and a sample transfer assembly, and adds a placement groove 170 for carrying and positioning the sample transfer assembly on the base carrier 100. Specifically: like Figures 3 to 6 As shown, the plate carrier 300 is a hard bracket positioned on the ground, and plays the role of bearing and supporting the base carrier plate 100; The rotating column 310 is a horizontally arranged hard column, one end of which is positioned on the plate carrier 300 and is rotatably connected to the plate carrier 300, and rotates around its own axis under the direct or indirect drive of the motor; The side surface of the base carrier plate 100 is fixed to the other end of the rotating column 310, and the fixing point is close to the bottom surface of the base carrier plate 100, and rotates under the drive of the rotating column 310; The horizontal magnet 110 and the vertical magnet 120 are both electromagnets, which are controlled to be powered on and off; The basic carrier rod 200 is suspended and positioned on the plate carrier 300 through the rod carrier 400; the rod carrier 400 is a hard frame that supports the basic carrier rod 200 so that it is higher than the basic carrier plate 100; The base carrier rod 200 is arranged horizontally, and the shadow lamp 210 and the image shooting assembly 220 are both positioned below the base carrier rod 200 and are both arranged tilted to illuminate the base carrier plate 100; The rod carrier 400 is preferably a rod-shaped frame arranged longitudinally; The sheet discharge slide 500 is a hard plate-shaped slide that is tilted and positioned on one side of the conveyor belt 001. The tested samples are separated from the base carrier 100 and then discharged from the sheet discharge slide 500. The placement groove 170 is a through groove, the depth of which is the thickness direction of the base carrier plate 100, and is located near the middle of the base carrier plate 100; like Figure 6 As shown, the template transfer assembly is positioned on the base carrier 100 and is used to drive the template to move in a controlled manner, including a carrier box 610, a rotating base 620, a wheel plate 630, a plate shifting assembly 640 and a column wheel 650; The carrier box 610 is a cylindrical box body with one side open, fixed in the placement groove 170, and does not protrude from the front of the base carrier plate 100; The rotating base 620 is a columnar base, coaxial with the carrier box 610, and is connected to the inner bottom of the carrier box 610 and rotates around its own axis. It has a built-in motor and is controlled to rotate relative to the carrier box 610. The plate shifting assembly 640 is an electric telescopic rod structure that is controlled to extend and retract. It is coaxial with the rotating base 620 and one end is fixed to the end of the rotating base 620 away from the inner bottom of the carrying box 610. The wheel-carrying plate 630 is a hard circular plate, coaxial with the plate shifting assembly 640 and fixed to the other end of the plate shifting assembly 640, and plays the role of carrying the positioning cylindrical wheel 650; The cylindrical wheel 650 is a cylindrical wheel body, and there are multiple of them. The ends are rotatably connected to the wheel carrier plate 630. The axis is perpendicular to the axis of the wheel carrier plate 630 and rotates around its own axis under the drive of the motor. The cylindrical wheel 650 has an internal electromagnet, which is controlled to be powered on and off.

[0044] The tinplate warpage detection device of the present application includes a control unit, which is used to control the coordinated operation of various components of the tinplate warpage detection device of the present application; the control unit is preferably a programmable logic controller.

[0045] Furthermore, an inductive proximity switch is provided on the top or one side of the conveyor belt 001. The inductive proximity switch is arranged close to the tinplate warpage detection device of the present application and is signal-connected to the control unit of the tinplate warpage detection device of the present application. When it detects that the tinplate product is approaching, it sends a switch signal to notify the tinplate warpage detection device to prepare for sampling (adsorption).

[0046] When the tinplate warpage detection device of the embodiment of the present application is running: 1. In the initial state, the front of the base carrier plate 100 faces the top surface of the conveyor belt 001, the horizontal magnets 110 and the vertical magnets 120 are both de-energized, and the wheel carrier plate 630 is protruding. At this point, the distance between the surface of the wheel carrier plate 630 closest to the conveyor belt 001 and the top surface of the conveyor belt 001 is less than 2 cm. The electromagnet built into the cylindrical wheel 650 on the wheel carrier plate 630 is also de-energized. 2. When the tinplate product to be sampled moves directly under the cylindrical wheel 650 (the proximity switch signal obtained and the speed of the conveyor belt 001 can be used to comprehensively determine whether the tinplate product is in place), the electromagnet built into the cylindrical wheel 650 is energized to attract and fix the sample; the cylindrical wheel 650 is then controlled to rotate to ensure that the sample contacts the sliding adjustment plate 130; the plate shifting assembly 640 is then controlled to operate to retract the wheel carrier plate 630. After the cylindrical wheel 650 is fully retracted into the receiving groove 170, the horizontal magnet 110 and the vertical magnet 120 are controlled to attract and fix the sample; 3. The base carrier 100 is then controlled to rotate 90 degrees, causing the sample positioned thereon to be in a vertical position (i.e., in a state ready for measurement). The distance measuring assembly 150 is then controlled to operate for distance measurement, and the shadowing lamp 210 and the image capturing assembly 220 are controlled to operate to obtain an image of the sample on the developing film 160. 4. After the test, the base carrier plate 100 is controlled to continue rotating 90 degrees so that its front side faces the air; thereafter, the sample transfer assembly is controlled to operate, the carrier wheel plate 630 is controlled to rotate and then rise, and then the sample on the base carrier plate 100 is discharged.

[0048] In order to further improve the stability of the tinplate warpage monitoring device of the present application in operation on the production line, improve the smoothness of the process in which the sample is attracted to the sample transfer assembly under the influence of magnetism, reduce the noise generated in the process in which the sample is attracted to the sample transfer assembly under the influence of magnetism, and reduce the probability of iron filings entering the gap between the rotating base 620, the carrier wheel plate 630, the plate shifting assembly 640 and the cylindrical wheel 650 after long-term use of the device, thereby ensuring the service life of the device and reducing the failure rate of the device; on the basis of the above embodiment, the embodiment of the present application cancels the setting of the placement groove 170 on the basic carrier plate 100, and sets a plurality of rope-receiving grooves 180 on the front of the basic carrier plate 100, and optimizes and improves the structure of the sample transfer assembly on the basis of the above embodiment, specifically: like Figures 7 to 9 As shown, the template transfer assembly includes a plate-shaped bracket 660, a connecting and pushing assembly 670, a rope roller 680 and a contact moving body 690; The rope-resting grooves 180 are long straight grooves, the length direction of which is the same as the length direction of the base carrier plate 100, and the number of the grooves 180 is two or more, and is used to accommodate the contact moving body 690; The developing sheet 160 is a plurality of sheets, and is arranged to avoid the rope-receiving groove 180; The plate-shaped bracket 660 is a rectangular plate-shaped rigid frame, parallel to the base carrier plate 100, and is arranged near the back of the base carrier plate 100, and plays the role of supporting the rope roller 680; The rope winding roller 680 is a cylindrical roller body used to reel in and release the contact moving body 690. There are two of them. The two contact moving bodies 690 have the same axial direction and the same width direction as the base carrier plate 100. The two rope winding rollers 680 are respectively close to the top and bottom surfaces of the base carrier plate 100. The connecting and moving assembly 670 is positioned between the back surface of the base carrier 100 and the plate-shaped bracket 660 and is used to control and timely change the distance between the two. It is preferably a telescopic rod structure and an airbag structure, and is controlled by the control unit. The contact moving body 690 is an annular belt-shaped rope body, the number of which is the same as the number of the rope-receiving grooves 180 , which is sleeved on the two rope-winding rollers 680 and is always in a straight state, and normally passes through the rope-receiving grooves 180 .

[0049] The film discharge chute 500 is located at the top of the conveyor belt 001. It is a hard plate body set at an angle. When the base carrier plate 100 is facing upward, the top surface of the base carrier plate 100 is close to the entrance of the film discharge chute 500; the exit of the film discharge chute 500 is located on one side of the conveyor belt 001.

[0050] When the tinplate warpage detection device of the embodiment of the present application is running: 1. In the initial state, the front surface of the base carrier plate 100 faces the top surface of the conveyor belt 001, the horizontal magnets 110 and the vertical magnets 120 are both in the off state, the contact moving body 690 protrudes from the base carrier plate 100 by no more than 1.5 cm, and the distance between the surface of the contact moving body 690 close to the conveyor belt 001 and the top surface of the conveyor belt 001 is less than 0.5 cm; 2. Before the tinplate product to be sampled moves directly under the contact moving body 690, the rope winding roller 680 is controlled to rotate, driving the contact moving body 690 to move at the same speed as the conveyor belt 001 at its bottom, and the horizontal magnet 110 and the vertical magnet 120 are controlled to remain energized; when the tinplate product moves directly under the contact moving body 690, it is attracted by the magnet and contacts the contact moving body 690, and then contacts the sliding adjustment plate 130, causing the movement to be stopped; thereafter, the rope winding roller 680 is controlled to stop rotating and the connecting and pushing assembly 670 is controlled to operate so that the contact moving body 690 enters the rope resting groove 180 and no longer protrudes from the base carrier 100; the sample is attracted and fixed by the horizontal magnet 110 and the vertical magnet 120; 3. The base carrier 100 is then controlled to rotate 90 degrees, causing the sample positioned thereon to be in a vertical position (i.e., in a state ready for measurement). The distance measuring assembly 150 is then controlled to operate for distance measurement, and the shadowing lamp 210 and the image capturing assembly 220 are controlled to operate to obtain an image of the sample on the developing film 160. 4. After the measurement, the base carrier 100 is controlled to continue to rotate 90 degrees so that its front is facing the air; thereafter, the template transfer assembly is controlled to operate, and the distance between the plate-shaped bracket 660 and the base carrier 100 is reduced so that the height of the template is higher than the sliding adjustment plate 130; thereafter, the rope roller 680 is controlled to rotate to discharge the template on the base carrier 100 from the sheet discharge slide 500.

[0051] Preferably, a brush is provided on the side wall of the placement groove 170 to brush off debris such as iron filings adhering to the movable body 690 when the movable body 690 moves in and out.

[0052] Preferably, the outlet of the sheet discharge slide 500 is located directly above the conveyor belt 001, and the discharged samples return to the conveyor belt 001.

[0053] Example 4

[0054] The difference between this embodiment and embodiment 3 is that: like Figure 10 As shown, the contact moving body 690 is a belt-shaped rope body, the number of which is the same as the number of the rope-receiving grooves 180. Both ends of each rope body are respectively wound and positioned on two rope rollers 680 and are always in a straight state. Under normal circumstances, it passes through the rope-receiving grooves 180.

[0055] Example 5

[0056] Considering that the device of the present application is automatically operated in the production workshop and frequently contacts different samples, although the magnets on the device are all electromagnets, it is inevitable that iron slag and burrs will accumulate near the electromagnets due to reasons such as the residual magnetism of the electromagnets after long-term use, affecting the fitting effect of the sample and thus affecting the accuracy of the detection results; although the use of manual regular cleaning can overcome the above problems, it requires manual participation, has a certain labor intensity and is difficult to maintain a relatively clean state in real time (continuously); to address the above problems, the embodiment of the present application adds an air blowing nozzle 230 on the basis of embodiment 4, regularly blows air to clean the front of the base carrier 100, and further optimizes the structure of the contact moving body 690 so that it cooperates with the air blowing nozzle 230 to achieve the function of wiping the base carrier 100; specifically: like Figure 11 and Figure 12 As shown, the air blowing nozzle 230 is connected to the air source, is controlled by the control unit to blow air, is positioned on the rod carrier 400, and regularly blows air to clean the front surface of the base carrier 100 when the front surface is facing upward; The contact moving body 690 includes a cleaning sheet 691 and a pulling rope 693; The cleaning sheet 691 is a strip-shaped sheet, preferably made of cotton, one end of which is wound around one of the rope rollers 680 and the other end of which is provided with a pulling rope 693; The pulling rope 693 is a belt-shaped rope body, and the number is two or more. One end is fixed to the cleaning sheet 691, and the other end is wound and positioned on another rope roller 680. The pulling rope 693 is adapted to the rope storage groove 180. The pulling rope 693 serves to carry the sample. During use, the cleaning sheet 691 is released regularly to cover the front of the base carrier 100. During the covering process, the air nozzle 230 is kept running to spray air toward the cleaning sheet 691, so that the cleaning sheet 691 adheres to the base carrier 100 and thus performs a wiping action. During the wiping process, iron filings, dust impurities and oil stains adhering to the front of the base carrier 100 will be wiped off to avoid affecting the fitting effect of the sample and the effect of the image taken.

[0057] Example 6

[0058] In order to further reduce costs and reduce the involvement of air sources, the embodiment of the present application further optimizes and improves the structure of the contact moving body 690 based on Example 5, eliminates the provision of the air blowing nozzle 230, and achieves regular cleaning of the base carrier 100 without the aid of the air blowing nozzle 230. Specifically, like Figure 13 As shown, the cleaning sheet 691 is a sheet-like capsule made of elastic fabric and filled with sponge. It is in an inflated state under normal circumstances. When the cleaning sheet 691 is wound on the rope roller 680, it is squeezed and flattened. When it moves to fit the base carrier plate 100, it bulges and contacts the base carrier plate 100.

[0059] Preferably, a long strip-shaped air vent 692 is provided on the cleaning sheet 691; the air vent 692 is arranged close to the pulling rope 693, and the length direction is the same as the width direction of the cleaning sheet 691; when the cleaning sheet 691 moves onto the base carrier 100, the air vent 692 faces the front of the base carrier 100; in the process of the cleaning sheet 691 being rolled up, the air vent 692 blows air toward the front of the base carrier 100 due to the squeezing of the cleaning sheet 691, replacing the blowing nozzle 230 to achieve cleaning.
