Description

Technical Field

[0001] The present invention relates to the technical field of tile production size inspection, and specifically to a size inspection system for tile production. Background Art

[0002] In traditional tile production, size inspection mainly relies on manual measurement using measuring tools or simple mechanical tools. Manual measurement is inefficient and is easily affected by the operator's experience and fatigue, resulting in inconsistent results. Although mechanical tools have been improved, they need to directly contact the tiles, which may scratch the surface. In the prior art, although some automated measurement devices have been applied, there are still obvious deficiencies: tiles often shift during transmission, and manual adjustment is time-consuming and laborious, affecting the measurement reliability; most devices are designed for fixed specifications and cannot be flexibly adjusted to adapt to various tile types; the measurement process often requires pausing the transmission, making it difficult to achieve continuous production and restricting the overall efficiency. Summary of the Invention

[0003] To overcome the defects of the above-mentioned prior art, the present invention provides the following technical solution: A size inspection system for tile production, including a support plate, on which a measurement part is fixedly installed overhead through a gantry. The measurement part is used to detect the contour size of the tile; the measurement part includes two symmetrically arranged second laser emitters and two symmetrically arranged first laser emitters. All the second laser emitters and first laser emitters are movably installed on a laser emitter bracket, and the laser emitter bracket is fixedly connected to the gantry; a positioning part is arranged on the side of the measurement part. The positioning part includes two symmetrically arranged push plates, and the two push plates are in contact and cooperation with the edge of the tile to be detected for calibrating the position of the tile; the two push plates can reciprocate relative to each other.

[0004] Preferably, the support plate is fixedly installed on support legs, and two support sliding tables are also fixedly installed on the support plate. The two support sliding tables are used to support two conveyor belts located at the positions of the measurement part and the positioning part. The two conveyor belts are arranged side by side and are used to jointly convey the tiles.

[0005] Preferably, two parallel push plate support sliding rods are fixedly installed on each push plate, and every two push plate support sliding rods are slidably installed on corresponding positioning side plates. The positioning side plates are fixedly installed on the support plate, and a rack sliding support plate is also fixedly installed between the two positioning side plates.

[0006] Preferably, a positioning drive motor is fixedly installed overhead in the middle of the rack sliding support plate. A gear is fixedly installed on the output shaft of the positioning drive motor. Two racks symmetrically located with respect to the origin of the gear are also slidably installed on the upper surface of the rack sliding support plate. Permanent magnets are fixedly installed at one ends of the two racks far away from the positioning drive motor.

[0007] Preferably, a push plate drive magnetic plate is fixedly installed in the middle of each push plate. The push plate drive magnetic plate is in sliding fit with the permanent magnet and in magnetic friction fit with the permanent magnet. The push plate is driven to move by the frictional force between the permanent magnet and the push plate drive magnetic plate.

[0008] Preferably, a first adjustment frame is arranged above the two first laser emitters. The two ends of the first adjustment frame are movably connected to the first laser emitters through two first adjustment connecting rods; a second adjustment frame is arranged above the two second laser emitters. The two ends of the second adjustment frame are movably connected to the two second laser emitters through two second adjustment connecting rods.

[0009] Preferably, a first adjustment frame guide rod and a first adjustment motor are fixedly installed on the laser emitter support. The first adjustment frame is in sliding fit with the first adjustment frame guide rod. A first adjustment screw rod is fixedly installed on the output shaft of the first adjustment motor. The first adjustment screw rod is in threaded drive fit with the first adjustment frame.

[0010] Preferably, a second adjustment motor is also fixedly installed on the laser emitter support. A second adjustment screw rod is fixedly installed on the output shaft of the second adjustment motor. The second adjustment screw rod is in threaded drive fit with the second adjustment frame.

[0011] Preferably, four adjusting electric cylinders arranged perpendicular to each other are fixedly installed at the position below the laser emitter support on the support plate. A light sensor support is fixedly installed at the end of the telescopic rod of each adjusting electric cylinder. A light sensor is fixedly installed on each light sensor support.

[0012] The present invention has the following beneficial effects compared with the prior art: (1) The present invention realizes the precise measurement of the contour size of the ceramic tile through the cooperation of the first laser emitter and the second laser emitter with the light sensor. The laser light irradiates the edge of the ceramic tile, and the change in the light intensity received by the light sensor can reflect the slight deviation of the size. Compared with the traditional method, this non-contact measurement avoids the errors and surface damage caused by contact, and ensures the measurement accuracy by adjusting the laser angle and the position of the light sensor, which is applicable to the production of high-quality ceramic tiles; (2) The positioning part of the present invention adopts a push plate and a positioning drive motor, and drives the push plate to contact the edge of the ceramic tile through a gear and a rack, automatically calibrating the position of the ceramic tile to make its edge parallel to the movement direction of the conveyor belt. This automated design reduces manual operation and ensures measurement consistency. At the same time, during the positioning of the ceramic tile, it does not affect the normal operation of the conveyor belt; (3) The measurement part of the present invention drives the first adjustment screw rod and the second adjustment screw rod respectively through the first adjustment motor and the second adjustment motor to adjust the angle of the laser emitter. This design enables the system to adapt to ceramic tiles of different sizes and shapes, and the cooperation between the adjustment link and the adjustment frame ensures accurate angle adjustment, enhancing the versatility and flexibility of the system; (4) The present invention uses a light sensor to monitor the occlusion of the laser light in real time. If the light intensity is abnormal, it can be judged whether the size of the ceramic tile is qualified or the placement is correct. This self-checking function can detect problems in time, avoid mismeasurement, and improve the reliability of quality control and the stability of the production line; (5) The double conveyor belt design of the present invention ensures the stable transmission of the ceramic tile, and the support sliding table provides stable support, cooperating with the positioning part and the measurement part to realize continuous operation. The ceramic tile is automatically positioned and measured during the transmission process without interrupting production, significantly improving the production efficiency and meeting the high-efficiency requirements of modern production lines.

[0020] The present invention provides a size inspection system for tile production, which includes a support plate 102. A measuring part is fixedly installed above the support plate 102 through a gantry 116, and the measuring part is used to detect the contour size of the tile. The measuring part includes two symmetrically arranged second laser emitters 128 and two symmetrically arranged first laser emitters 129. All the second laser emitters 128 and the first laser emitters 129 are movably installed on a laser emitter bracket 117, and the laser emitter bracket 117 is fixedly connected to the gantry 116. A positioning part is arranged on the side of the measuring part. The positioning part includes two symmetrically arranged push plates 109. The two push plates 109 are in contact with the edge of the tile to be detected and are used to calibrate the position of the tile. The two push plates 109 can reciprocate relative to each other. The support plate 102 is fixedly installed on support legs 101. Two support sliding platforms 103 are also fixedly installed on the support plate 102. The two support sliding platforms 103 are used to support two conveyor belts 104 located at the positions of the measuring part and the positioning part. The two conveyor belts 104 are arranged side by side and are used to jointly convey the tiles. Two parallel push plate support slide rods 106 are fixedly installed on each push plate 109. Every two push plate support slide rods 106 are slidably installed on corresponding positioning side plates 105. The positioning side plates 105 are fixedly installed on the support plate 102. A rack sliding support plate 123 is also fixedly installed between the two positioning side plates 105. A positioning drive motor 112 is fixedly installed above the middle of the rack sliding support plate 123. A gear 111 is fixedly installed on the output shaft of the positioning drive motor 112. Two racks 110 that are symmetric about the origin of the gear 111 are also slidably installed on the upper surface of the rack sliding support plate 123. Permanent magnets 108 are fixedly installed at one ends of the two racks 110 away from the positioning drive motor 112. A push plate drive magnetic plate 107 is fixedly installed in the middle of each push plate 109. The push plate drive magnetic plate 107 is slidably matched with the permanent magnet 108, and the push plate drive magnetic plate 107 is in magnetic friction cooperation with the permanent magnet 108. The push plate 109 is driven to move by the frictional force between the permanent magnet 108 and the push plate drive magnetic plate 107. A first adjustment frame 121 is arranged above the two first laser emitters 129. The two ends of the first adjustment frame 121 are movably connected to the first laser emitters 129 through two first adjustment connecting rods 122. A second adjustment frame 124 is arranged above the two second laser emitters 128. The two ends of the second adjustment frame 124 are movably connected to the two second laser emitters 128 through two second adjustment connecting rods 125. A first adjustment frame guide rod 118 and a first adjustment motor 120 are fixedly installed on the laser emitter bracket 117. Among them, the first adjustment frame 121 is slidably matched with the first adjustment frame guide rod 118. A first adjustment lead screw 119 is fixedly installed on the output shaft of the first adjustment motor 120. The first adjustment lead screw 119 is in threaded drive cooperation with the first adjustment frame 121.A second adjustment motor 127 is also fixedly installed on the laser emitter bracket 117. A second adjustment lead screw 126 is fixedly installed on the output shaft of the second adjustment motor 127. The second adjustment lead screw 126 is in threaded driving cooperation with the second adjustment bracket 124. Four adjustment cylinders 113 arranged perpendicular to each other are fixedly installed at a position below the laser emitter bracket 117 on the support plate 102. A light sensor bracket 114 is fixedly installed at the end of the telescopic rod of each adjustment cylinder 113. A light sensor 115 is fixedly installed on each light sensor bracket 114.

[0021] The working principle of a size inspection system for tile production disclosed in the present invention is as follows: The produced tiles are placed on the conveyor belt 104, and the tiles are conveyed between the two push plates 109 through the two conveyor belts 104. At this time, the positioning drive motor 112 is started, and the output shaft of the positioning drive motor 112 will drive the gear 111 to rotate (the output shaft of the positioning drive motor 112 rotates in a cyclic reciprocating manner, rotating clockwise and then counterclockwise). The gear 111 drives the two racks 110 to move relative to each other, and the two racks 110 drive the corresponding permanent magnets 108 to move relative to each other. The permanent magnet 108 drives 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 tile, making the two push plates 109 contact the edge of the tile, and then pushing the tile to be straightened so that the edge of the tile is parallel to the moving direction of the conveyor belt 104. At this time, since the push plate 109 contacts the tile, the push plate 109 cannot move forward, and the push plate drive magnetic plate 107 cannot move forward either. At this time, relative sliding occurs between the push plate drive magnetic plate 107 and the permanent magnet 108. When the permanent magnet 108 slides to one end position of the push plate drive magnetic plate 107, the gear 111 starts to rotate in the reverse direction, and then the two push plates 109 move away from each other. When the push plate 109 moves to contact the conveyor belt 104, the push plate 109 cannot move forward. At this time, the permanent magnet 108 will also have relative sliding with the push plate drive magnetic plate 107, sliding from one end of the push plate drive magnetic plate 107 to the other end. During the process of the push plate 109 positioning the tile, the tile will have relative sliding with the conveyor belt 104 (depending on the friction between the tile and the conveyor belt 104), but it will not affect the conveyor belt 104 from conveying other tiles.

[0022] When the push plate 109 separates from the ceramic tile, the ceramic tile will continue to move driven by the conveyor belt 104. When the ceramic tile moves directly below the measuring part, it will block the light rays emitted by the first laser emitter 129 and the second laser emitter 128. Before that, it is necessary to adjust the angles of the light rays emitted by the first laser emitter 129 and the second laser emitter 128. Specifically, place a ceramic tile of standard size directly below the laser emitter bracket 117, and then let the light rays emitted by the second laser emitter 128 and the first laser emitter 129 shine on the edge position of the ceramic tile, so that the edge of the ceramic tile blocks generally the light rays emitted by the second laser emitter 128 and the first laser emitter 129. At this time, the light sensor 115 located below is moved to the path of the light rays emitted by the second laser emitter 128 and the first laser emitter 129 to receive the emitted light rays. The light sensor 115 is controlled by the adjustment electric cylinder 113 at the corresponding position, and the telescopic rod of the adjustment electric cylinder 113 drives the light sensor 115 to move. When the ceramic tile to be measured moves past the light rays emitted by the two second laser emitters 128, the ceramic tile will block the light rays of the two second laser emitters 128. If the light sensors 115 corresponding to the two second laser emitters 128 both receive half (half of the light intensity in the ideal state) of the light intensity, it means that the size of the ceramic tile in the direction of the two second laser emitters 128 is qualified. If the light rays emitted by one of the second laser emitters 128 are completely blocked (normally, the light intensities received by the light sensors 115 corresponding to the two second laser emitters 128 are the same. Here, a unilateral example is given), for example, the corresponding light sensor 115 cannot receive the optical signal. At this time, it means that the size of the ceramic tile is too large. If the light intensity received by the light sensor 115 at the corresponding position is too large (the light rays emitted by the second laser emitter 128 are completely received), at this time, it means that the size of the ceramic tile is too small (refining the light intensity received by the light sensor 115 and combining with the width of the light rays of the second laser emitter 128 can make the measurement result more accurate). If the light sensor 115 corresponding to one of the second laser emitters 128 completely receives the light rays and the light sensor 115 corresponding to the other second laser emitter 128 does not receive the light rays, it means that the ceramic tile is not placed correctly (the push plate 109 does not work properly, playing a self-checking function). The principle of measuring the size of the ceramic tile by the two first laser emitters 129 is the same as that of the second laser emitter 128. The directions of measuring the size of the ceramic tile by the two first laser emitters 129 and the two second laser emitters 128 are perpendicular (however, the optical signals detected by the light sensors 115 corresponding to the two first laser emitters 129 will not be simultaneous because the ceramic tile is in a moving state. Therefore, as long as one light sensor 115 receives half of the signal and the other light sensor 115 does not receive the optical signal, or receives a complete optical signal, the size of the ceramic tile is unqualified).The angles at which the two second laser emitters 128 emit light are adjusted by controlling the second adjustment motor 127. The output shaft of the second adjustment motor 127 drives the second adjustment lead screw 126 to rotate. The second adjustment lead screw 126 drives the second adjustment bracket 124 to move along the axial direction of the second adjustment lead screw 126. The second adjustment bracket 124 drives the two second laser emitters 128 to swing on the laser emitter bracket 117 through two second adjustment connecting rods 125, thereby adjusting the angles of the two second laser emitters 128. The angles at which the two first laser emitters 129 emit light are adjusted by controlling the first adjustment motor 120. The output shaft of the first adjustment motor 120 drives the first adjustment lead screw 119 to rotate. The first adjustment lead screw 119 drives the first adjustment bracket 121 to move along the axial direction of the first adjustment lead screw 119. The first adjustment bracket 121 drives the two first laser emitters 129 to swing on the laser emitter bracket 117 through two first adjustment connecting rods 122, thereby adjusting the angles of the two first laser emitters 129.
