A tin can warping detection device

Abstract

The application discloses a tin plate warping detection device, and relates to the technical field of measurement and detection equipment. The warping detection device comprises a base carrier plate and a base carrier rod. The application uses a magnet positioned on the base carrier plate to replace manual positioning of a detected sample plate. A sliding adjustment plate is slidably positioned on the base carrier plate to flexibly adjust the placement position of the sample plate, so that the end of different detected sample plates away from the sliding adjustment plate can fall into the detection range of a distance measuring assembly. The distance measuring assembly is used to measure the warping degree. A fixed shadow lamp is used to obliquely irradiate the raised end of the detected sample plate to make the raised end cast a shadow on the base sample plate. An image shooting assembly is used to shoot and record the shadow as a basis for judging the warping degree. The data obtained by the distance measuring assembly and the image shooting assembly are mutually verified to avoid errors. The tin plate warping detection device has the technical effects of convenient and efficient detection, low labor intensity in the detection process, few people required for detection, and high accuracy of the obtained results.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metrological detection equipment, in particular to a tinplate warping detection device. BACKGROUND

[0002] The warping of a tinplate product refers to the unevenness and bending of the tinplate in the production and processing process. The warping is divided into L warping and C warping, and the height of the C warping has different effects on the use of downstream customers. The warping value directly determines the grade of the product, so warping detection is particularly important.

[0003] The current measurement method for the warping of a single tinplate is as follows: a relatively straight back plate is made, the sample plate is attached to the back plate after sampling, so that the sample plate is in a natural state of sagging, and the distance between the edge of the sample plate that is warped and the back plate is measured by using a steel ruler. The measured value is the warping height. This scheme requires two people to operate simultaneously, one person presses the upper end of the sample plate to make the sample plate closely attached to the back plate, and the other person measures the warping height by using a steel ruler. Since there are measurement errors in the steel ruler itself and deviations in the human estimated reading, the final value is not accurate. Moreover, the entire process involves multiple steps such as manually taking the sample plate, manually attaching the plate, manually positioning, manually measuring, manually reading, and manually recording. The entire operation process is relatively complicated and complex, and is prone to operation deviations and errors. Moreover, multiple people are required to operate, which is not conducive to the efficient performance of metrological detection.

[0138] Embodiment 4

[0139] The difference between the embodiment of the present application and the embodiment 3 is as follows:

[0141] Embodiment 5

[0142] Considering that the device of the present application is automatically operated in a production workshop, it will frequently contact different templates. Although the magnets on the device are all electromagnets, it is still inevitable to accumulate iron slag burrs at the position close to the electromagnet due to the residual magnetism of the electromagnet and other reasons after long-term use, which affects the fitting effect of the template and further affects the accuracy of the detection result. Although the above problems can be overcome by manual periodic cleaning, it needs manual participation, has a certain labor intensity, and is difficult to maintain a relatively clean state in real time (continuously). In view of the above problems, the embodiment of the present application adds a blowing nozzle 230 on the basis of embodiment 4 to periodically blow and clean the front surface of the base carrier plate 100, and further optimizes the structure of the contact moving body 690 to realize the function of wiping the base carrier plate 100 in cooperation with the blowing nozzle 230. Specifically:

[0143] As shown in Figure 11 and Figure 12 , the blowing nozzle 230 is in communication with the gas source and is controlled by the control unit to blow, and is positioned on the rod carrier 400. When the front surface of the base carrier plate 100 is upward, it periodically blows and cleans the front surface thereof;

[0144] The contact moving body 690 includes a cleaning sheet body 691 and a pulling rope 693;

[0145] The cleaning sheet body 691 is a belt-shaped sheet body, and the material is preferably cotton. One end is wound and positioned on one of the rope winding rollers 680, and the other end is positioned with the pulling rope 693;

[0146] The pulling rope 693 is a belt-shaped rope body, the number of which is 2 or more. One end is fixed on the cleaning sheet body 691, and the other end is wound and positioned on the other rope winding roller 680. The pulling rope 693 is matched with the rope resting groove 180. The pulling rope 693 plays a role in carrying the template;

[0147] During use, the cleaning sheet body 691 is periodically released to cover the front surface of the base carrier plate 100. During the covering process, the blowing nozzle 230 is kept running to blow air to the cleaning sheet body 691, so that the cleaning sheet body 691 is attached to the base carrier plate 100 and thus realizes the wiping action. During the wiping process, the iron filings, dust impurities, oil stains and the like adhering to the front surface of the base carrier plate 100 are wiped off, so as to avoid affecting the fitting effect of the template and the effect of the taken image.

[0148] Embodiment 6

[0149] In order to further reduce the cost and reduce the participation of the gas source, the structure of the contact moving body 690 is further optimized and improved based on the embodiment 5, the setting of the blowing nozzle 230 is cancelled, and the periodic cleaning of the base carrier plate 100 is realized without the help of the blowing nozzle 230, and the specific is:

[0150] As shown in Figure 13 The cleaning sheet body 691 is a sheet-shaped capsule made of elastic cloth, and the inside is filled with sponge and is in a swollen state under normal circumstances; when the cleaning sheet body 691 is wound on the winding rope roller 680, it is crushed due to extrusion, and when it is moved to adhere to the base carrier plate 100, it is inflated and contacts the base carrier plate 100.

[0151] Preferably, the cleaning sheet body 691 is provided with a long strip-shaped air vent 692; 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 body 691; when the cleaning sheet body 691 is moved to the base carrier plate 100, the air vent 692 faces the front surface of the base carrier plate 100; during the winding process of the cleaning sheet body 691, the air vent 692 blows air towards the front surface of the base carrier plate 100 due to the extrusion of the cleaning sheet body 691, and realizes the blowing instead of the blowing nozzle 230.

[0152] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
