[0021] The working principle of the size inspection system for ceramic tile production is as follows: the produced ceramic tile is placed on the conveying belt 104, the ceramic tile is conveyed between the two push plates 109 through the two conveying belts 104, the positioning drive motor 112 is started at this time, the output shaft of the positioning drive motor 112 drives the gear 111 to rotate (the output shaft of the positioning drive motor 112 rotates cyclically and reciprocally, rotates clockwise and then counterclockwise), the gear 111 drives the two racks 110 to move relatively, the two racks 110 drive the corresponding permanent magnets 108 to move relatively, the permanent magnets 108 drive the push plate drive magnetic plate 107 to move synchronously through friction (the normal pressure of the friction comes from the magnetic force between the two), the push plate drive magnetic plate 107 drives the push plate 109 to move towards the ceramic tile, so that the two push plates 109 contact the edges of the ceramic tile, and then the ceramic tile is pushed to be aligned, so that the edges of the ceramic tile are parallel to the movement direction of the conveying belt 104, at this time, since the push plate 109 contacts the ceramic tile, the push plate 109 cannot continue to move, and the push plate drive magnetic plate 107 cannot continue to move, at this time, the push plate drive magnetic plate 107 and the permanent magnet 108 slide relatively, when the permanent magnet 108 slides to the position of one end of the push plate drive magnetic plate 107, the gear 111 starts to rotate reversely, then the two push plates 109 move away from each other, when the push plate 109 moves to contact the positioning side plate 105, the push plate 109 cannot continue to move, at this time, the permanent magnet 108 slides relatively to the push plate drive magnetic plate 107 from one end to the other end of the push plate drive magnetic plate 107. During the positioning of the ceramic tile by the push plate 109, the ceramic tile slides relatively to the conveying belt 104 (depending on the friction between the ceramic tile and the conveying belt 104), but does not affect the conveying of other ceramic tiles by the conveying belt 104.
[0022] When the push plate 109 is separated from the tile, the tile will continue to move under the drive of the conveyor belt 104, and when the tile moves directly below the measuring part, it will block the light emitted by the first laser emitter 129 and the second laser emitter 128. Before that, the angle of the light emitted by the first laser emitter 129 and the second laser emitter 128 needs to be adjusted. Specifically, a standard size tile is placed directly below the laser emitter bracket 117, and then the light emitted by the second laser emitter 128 and the first laser emitter 129 is allowed to shine on the edge of the tile, so that the edge of the tile blocks the light emitted by the second laser emitter 128 and the first laser emitter 129. At this time, the light sensor 115 located below moves to the path of the light emitted by the second laser emitter 128 and the first laser emitter 129 for receiving the emitted light. The light sensor 115 is controlled by the adjusting cylinder 113 at the corresponding position, and the adjusting cylinder 113 drives the light sensor 115 to move through the telescopic rod. When the tile to be measured moves through the light emitted by the two second laser emitters 128, the tile will block the light of the two second laser emitters 128, and if the corresponding light sensor 115 of the two second laser emitters 128 receives half (ideally half of the light intensity) of the light intensity, it means that the size of the tile in the direction of the two second laser emitters 128 is qualified. If the light emitted by one of the second laser emitters 128 is completely blocked (normally, the light intensity received by the corresponding light sensor 115 of the two second laser emitters 128 is the same, and here only one side is taken as an example), for example, the corresponding light sensor 115 cannot receive the light signal, which means that the size of the tile is too large. If the light intensity received by the corresponding light sensor 115 is too large (the light emitted by the second laser emitter 128 is completely received), it means that the size of the tile is too small (the intensity of the light received by the light sensor 115 is refined, and combined with the width of the light emitted by the second laser emitter 128, the measurement result can be more accurate). If the corresponding light sensor 115 of one of the second laser emitters 128 completely receives the light, and the corresponding light sensor 115 of the other second laser emitter 128 does not receive the light, it means that the tile is not properly positioned (the push plate 109 does not work properly, and functions as a self-checking function). The principle of the size of the tile detected by the two first laser emitters 129 is the same as that of the second laser emitters 128, and the directions of the sizes of the tile detected by the two first laser emitters 129 and the two second laser emitters 128 are perpendicular (but the light signals detected by the corresponding light sensors 115 of the two first laser emitters 129 will not be received at the same time, because the tile is in a moving state, so only one light sensor 115 receives half of the signal, and the other light sensor 115 does not receive the light signal or receives the complete light signal, and the size of the tile is not qualified).The angle of the light emitted by the two second laser emitters 128 is adjusted by controlling the second adjusting motor 127, the output shaft of the second adjusting motor 127 drives the second adjusting screw 126 to rotate, the second adjusting screw 126 drives the second adjusting frame 124 to move along the axial direction of the second adjusting screw 126, the second adjusting frame 124 drives the two second laser emitters 128 to swing on the laser emitter support 117 through the two second adjusting connecting rods 125, so as to adjust the angle of the two second laser emitters 128, the angle of the light emitted by the two first laser emitters 129 is adjusted by controlling the first adjusting motor 120, the output shaft of the first adjusting motor 120 drives the first adjusting screw 119 to rotate, the first adjusting screw 119 drives the first adjusting frame 121 to move along the axial direction of the first adjusting screw 119, the first adjusting frame 121 drives the two first laser emitters 129 to swing on the laser emitter support 117 through the two first adjusting connecting rods 122, so as to adjust the angle of the two first laser emitters 129.
