Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Fig. 4 shows the state diagram of the present invention when the edge contour measuring system for ceramic plate is used in conjunction with the belt conveyer, it can be known that it is used in conjunction with the belt conveyer to detect the contour degree of the edge of the ceramic plate conveyed by the belt conveyer.

In order to facilitate the technical solution disclosed by the present invention to be fully understood by those skilled in the art, the following detailed description is made in combination with the specific embodiments, fig. 1 and fig. 2 respectively show a schematic perspective view and a side view of a rim profile measuring system suitable for a porcelain plate in the present invention, and it can be seen that the system mainly comprises a support frame 1, a laser range finder 2, and a rotation driving unit 3. The support frame 1 spans across the belt conveyor and comprises a front support plate 11, a rear support plate 12 and a transverse bearing plate 13. The front supporting plate 11 and the rear supporting plate 12 are symmetrically arranged at the front side and the rear side of the belt conveyor to support the transverse bearing plate 13. The rotary drive unit 3 is supported by a horizontal bearing plate 13. The laser range finder 2 is arranged right below the transverse bearing plate 13 and performs circular rotary motion under the action of the driving force of the rotary driving unit 3. In the actual measuring process, whether the shape tolerance and the size tolerance of each area of the edge of the ceramic disc meet the requirements or not is sequentially measured in the circular rotating process by the laser range finder 2, and then whether the profile tolerance of the ceramic disc meets the standard or not is judged. The whole detection process is time-saving and labor-saving, and is not influenced by the operation experience and the working state of a detection worker, so that the phenomena of 'missing detection' and 'false detection' are avoided. In addition, the laser range finder 2 rotates around a reference shaft all the time in the measuring process and keeps at the same position height, so that the accuracy of measuring the edge profile of the ceramic disc is ensured.

As a further refinement of the above-described structure of the rim profile measuring system suitable for porcelain plates, the rotary drive unit 3 comprises a hollow rotary platform 31 and a connecting transition piece 32, as shown in fig. 2. The hollow rotary platform 31 is fixed on the transverse bearing plate 13. The connecting transition piece 32 is fixed with the laser range finder 2 into a whole, and the whole body is connected with the hollow rotating platform 31. Therefore, the connection transition pieces with different sizes can be conveniently adapted according to the specific model of the pre-tested ceramic disc, so that the scanning area of the laser range finder 2 can be conveniently and quickly adjusted, and the application range of the disc edge profile measuring system suitable for the ceramic disc is expanded.

As shown in fig. 3, the connecting transition piece 32 is preferably composed of a transverse plate 321, a vertical plate 322 and a coupling screw 323. The transverse plate 321 is detachably fixed to the hollow rotary platform 31. The vertical plate 322 is used directly for mounting the laser rangefinder 2 and is connected angularly to the transverse plate 321 by means of coupling screws 323. The horizontal plate 321 is provided with a connecting through hole 3211 through which the connecting screw 323 freely passes, and a screw hole for screwing the connecting screw 323 extends downward from the top wall of the vertical plate 322. The coupling through-hole 3211 is an elongated kidney-shaped hole and extends in the front-rear direction. Therefore, when the position of the scanning area of the laser distance measuring instrument 2 needs to be adjusted, the laser distance measuring instrument 2 is dragged along the radial direction only by loosening the connecting screw 323 until the scanning area formed by the laser distance measuring instrument 2 completely covers the edge of the ceramic disc, and finally the connecting screw 323 is locked again, so that the whole operation process is convenient and fast, and the connecting transition piece 32 does not need to be replaced integrally.

The stability of support frame 1 self structure has vital influence to the process that laser range finder 2 measured, for example, when support frame 1 when the slope takes place because of the unbalanced stress, laser range finder 2 also follows the slope that takes place, and then has increased the size measurement error at porcelain plate edge, finally influences the judgement of profile tolerance. In view of this, as shown in fig. 1, the disc edge profile measurement system for ceramic discs is further provided with a front auxiliary support seat 4 and a rear auxiliary support seat 5 according to the actual field application scenario. The front auxiliary support seat 4 is arranged right in front of the front support plate 11 and always abuts against the front support plate 11. The rear auxiliary support seat 5 is arranged right behind the rear support plate 12 and always abuts against the rear support plate 12. The mutual cooperation of leading auxiliary supporting seat 4 and rearmounted auxiliary supporting seat 5 is used and can be promoted the structural stability of support frame 1 effectively, ensures that horizontal bearing plate 13 remains in the horizontality throughout, improves a good foreshadowing for the follow-up high accuracy measurement of the radium-shine distancer of laser.

The relative distance between the ceramic disc and the laser range finder 2 has a crucial influence on the profile tolerance measurement result. When the distance is too large, the difference between the dimension measured by the laser distance meter 2 and the theoretical dimension is large, so that the judgment of the edge profile of the ceramic disc is influenced, and therefore, as shown in fig. 1, a jacking unit 6 is additionally arranged in the edge profile measuring system suitable for the ceramic disc. The jacking unit 6 is arranged right below the belt conveying line and is opposite to the laser range finder 2. When the ceramic disc to be detected stops under the laser range finder 2, the jacking unit 6 acts to jack the ceramic disc to perform displacement motion relative to the laser range finder 2 until the ceramic disc keeps a proper distance relative to the laser range finder 2.

It is known that the jacking unit 6 can adopt various designs to realize jacking of the porcelain plate, but an embodiment with a simple design, easy implementation and convenient later maintenance is recommended here, specifically as follows: as shown in fig. 2, the top-supporting unit 6 includes a fixed plate 61, a front bearing plate 62, a rear bearing plate 63, a sliding frame 64, a front slide rail slider assembly 65, a rear slide rail slider assembly 66, a supporting column 67, a top-supporting plate 68, and a linear driving portion 69. The sliding frame 64 is arranged right above the fixed plate 61, and the front and rear sides thereof are symmetrically provided with a front bearing plate 62 and a rear bearing plate 63. The sliding frame 64 is formed by sequentially connecting a front sliding plate 641, a flat base plate 642, and a rear sliding plate 643. The front slide rail slider assembly 65 is connected between the front slide board 641 and the front bearing board 62. The rear slide block assembly 66 is connected between the rear sliding plate 643 and the rear bearing plate 63. The linear driving portion 69 is disposed directly below the flat base plate 642 to drive the sliding frame 64 to perform the sliding movement in the up-down direction. The top tray plate 68 is arranged in parallel directly above the flat base plate 642. The support column 67 is vertically disposed and connected between the flat base plate 642 and the top board 68.

Finally, it should be noted that the linear driving portion 69 can be selected preferentially from an air cylinder, a hydraulic cylinder or a linear motor according to different practical application scenarios.
