Description

Technical Field

[0001] The invention relates to a detection device, in particular to an integrated detection device and method for the surface and cracks of a marble tile. Background Art

[0002] Marble tile is a kind of tile whose appearance imitates natural marble. It uses advanced printing technology to print the texture, color and texture of marble onto the surface of the tile, with an aesthetic effect similar to natural marble. In order to improve the production efficiency and product quality of marble tiles, it is necessary to inspect the surface of marble tiles during production. In order to control the production quality of marble tiles, an integrated detection device will be used during the inspection to detect the surface and cracks of marble tiles.

[0003] When the current integrated detection device for the surface and cracks of marble tiles is used, in order to achieve comprehensive detection of the front and back sides of the marble tiles at the same workstation, a flipping device is usually equipped. After the detection of one side of the marble tile is completed, the marble tile is flipped over by the flipping device so as to detect the other side. However, during the flipping process, since the flipping device usually clamps or fixes the edge of the marble tile, this edge is often partially blocked by the clamping structure of the flipping device. Due to the coverage of the edge of the marble tile by these fixing devices, the edge area of ​​the marble tile cannot be fully exposed when flipping, so that the edge of the tile cannot be clearly scanned and detected during detection. This blocking problem directly affects the effect of the detection device on the comprehensive scanning of the tile surface, especially when detecting the edge area of ​​the tile, omissions or inaccurate identification may occur, which not only limits the comprehensive and no-dead-angle detection of the front and back sides and the edge of the tile, but also may affect the discovery and judgment of minor defects such as cracks and flaws, thereby affecting the accuracy and reliability of the entire detection.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1~Figure 4In an embodiment of the present invention, a marble tile surface and crack integrated detection device comprises a machine body 1 and a conveyor belt 2 arranged on the machine body 1, wherein two lifting mechanisms are symmetrically arranged on the machine body 1, and a clamping and flipping detection structure is arranged on the machine body 1 above the lifting mechanism; the clamping and flipping detection structure comprises two mounting mechanisms symmetrically mounted on the machine body 1, a clamping and flipping mechanism connected between the two mounting mechanisms, a lifting detection mechanism connected to the clamping and flipping mechanism, and a transmission mechanism connected to the clamping and flipping mechanism and the lifting detection mechanism, wherein the transmission mechanism is mounted on the On the clamping and turning mechanism; when the lifting mechanism is in action, it is used to lift the marble tiles conveyed on the conveyor belt 2 to the position of the clamping and turning mechanism, and the clamping and turning mechanism clamps the edges of the marble tiles on both sides. When the transmission mechanism is in action, it is used to drive the lifting detection mechanism to detect the marble tiles on the clamping and turning mechanism. When the lifting detection mechanism moves to one side of the marble tiles, the transmission mechanism drives the clamping and turning mechanism to turn over 180 degrees between the two installation mechanisms. During the turning process of the clamping and turning mechanism, the lifting detection mechanism is driven to rise and give way and then fall again.

[0021] In this embodiment, the two lifting mechanisms operate synchronously. When the marble tiles are conveyed to the lifting mechanism by the conveyor belt 2 on the machine body 1, the lifting mechanism lifts the marble tiles on the conveyor belt 2 to the clamping and flipping mechanism. The two sides of the marble tiles can be clamped by the clamping and flipping mechanism. At this time, the lifting mechanism is reset, and the transmission mechanism operates, so that the lifting detection mechanism operates, and the marble tiles on the clamping and flipping structure can be inspected and scanned. After the lifting detection mechanism completes the inspection of the marble tiles, it moves to one side of the marble tiles and continues to move. At this time, the transmission mechanism drives the clamping and flipping mechanism to adjust the marble tiles to flip 180 degrees. During the flipping process of the clamping and flipping mechanism, the lifting detection mechanism performs a lifting and giving way movement and then falls and resets. Then, when the lifting detection mechanism moves back and forth for inspection, the marble tiles after flipping can be inspected.

[0022] See also Figure 1 , Figure 3 As a further solution of the present invention, the two jacking mechanisms are respectively arranged on the machine body 1 between the two adjacent conveyor belts 2; the jacking mechanism includes a jacking plate 3 and a cylinder 5 whose piston rod is fixedly connected to the bottom center of the jacking plate 3; guide columns 4 are fixedly connected on both sides of the jacking plate 3, the guide columns 4 are slidably inserted into the machine body 1, and the cylinder 5 is installed on the machine body 1.

[0023] In this embodiment, two lifting mechanisms are arranged on the machine body 1 between two adjacent conveyor belts 2. When the lifting mechanisms are in lifting motion, the normal transportation operation of the conveyor belts 2 will not be affected, thereby ensuring the use effect. Two guide columns 4 are arranged at both ends of the lifting plate 3, and the two guide columns 4 are plugged into the machine body 1. When the cylinder 5 lifts the lifting plate 3, the lifting plate 3 can be lifted smoothly. The other lifting mechanism is controlled by the same upper device to ensure synchronous lifting and lowering adjustment.

[0024] See also Figure 5 , Figure 6 As a further solution of the present invention, the mounting mechanism includes two brackets 6 symmetrically mounted on the body 1 and a connecting ring 8 arranged on each of the brackets 6; four guide shafts 7 are fixedly connected to a circular array on one side of the connecting ring 8, and the other ends of the four guide shafts 7 are fixedly connected to the bracket 6.

[0025] In this embodiment, two brackets 6 are firmly fixed on the body 1 to form a stable support frame, so that various types of equipment between the brackets 6 can be accurately installed and used on the structure of the body 1. This design not only ensures the stability of the equipment, but also ensures the efficiency and accuracy of the equipment during operation. The guide shaft 7 and the connecting ring 8 meet the connection and use requirements of the clamping and flipping mechanism.

[0026] See also Figure 7~Figure 11 As a further solution of the present invention, the clamping and flipping mechanism includes a flip frame 9, an elliptical disk 10 symmetrically fixedly connected to the center parts of both sides of the flip frame 9, two bidirectional screw rods 11 symmetrically rotatably connected to the flip frame 9, and two alternating receiving components symmetrically arranged on the flip frame 9; one end of one of the bidirectional screw rods 11 is coaxially fixed with the output shaft of the first motor 12 installed on the flip frame 9, the first motor 12 is installed on the flip frame 9, and one end of the two bidirectional screw rods 11 is connected by a transmission belt.

[0027] The alternating bearing assembly includes a moving frame 13 whose two ends are threadedly connected to the two bidirectional screw rods 11, two bearing bosses 15 slidably connected to the moving frame 13, and a sleeve 18 connected to the bearing bosses 15; the moving frame 13 is symmetrically provided with sliding grooves 14, the bearing bosses 15 are slidably connected in the sliding grooves 14, a driving rod 16 is fixedly connected at the center of one side of the bearing bosses 15, and the driving rod 16 is slidably inserted into the flip frame 9; one end of the driving rod 16 is fixedly connected to a resistance block 17, the resistance block 17 is slidably connected to a circular inclined groove 19 provided on the inner wall of the sleeve 18, and the sleeve 18 slides on four guide shafts 7.

[0028] In this embodiment, the sleeve 18 slides on the guide shaft 7. The guide shaft 7 is fixedly installed on the bracket 6, so that the sleeve 18 can only slide horizontally on the guide shaft 7, and the sleeve 18 does not have a rotation effect. When the first motor 12 drives the bidirectional screw rod 11 to rotate, the two moving frames 13 threadedly connected to the bidirectional screw rod 11 will move closer to or farther away from each other. The sliding distance of the moving frame 13 on the flip frame 9 is the length of the driving rod 16, ensuring that when the moving frame 13 slides, the receiving boss 15 and the sleeve 18 can be connected through the driving rod 16 and the abutment block 17. When the flip frame 9 flips, the abutment block 17 slides in the circular bevel groove 19, and the sleeve 18 remains in place. When flipping, the abutment block 17 will abut in the circular bevel groove 19. Through the design of the circular bevel groove 19, when the two abutment blocks 17 are respectively at the top and bottom of the inner wall of the circular bevel groove 19, At this time, the abutment block 17 at the top of the circular bevel groove 19 will abut against the lower side of the circular bevel groove 19, and the abutment block 17 at the bottom of the circular bevel groove 19 will abut against the higher side of the circular bevel groove 19, so that the extension lengths of the two abutment blocks 17 are different, the abutment block 17 at the bottom extends longer, and the abutment block 17 at the top extends shorter. When the flip frame 9 is flipped to ninety degrees, the two abutment blocks 17 are at the same height in the circular bevel groove 19, so the two abutment blocks 17 extend the same distance. By design, when the flip frame 9 is flipped, the two receiving bosses 15 inside the moving frame 13 can be alternately extended to support the bottom of the marble tile. This design can make the upward surface of the marble tile exposed as a whole when the upward surface of the marble tile is detected, and will not block the comprehensive detection, thereby improving the detection effect of the marble tile.

[0029] See also Fig.14 As a further solution of the present invention, the lifting detection mechanism includes two connecting columns 33 symmetrically fixed to the inner wall of the body 1, a mounting frame 28 slidably connected to the two connecting columns 33 at both ends, and a detector 32 connected to the mounting frame 28; both ends of the bottom of the mounting frame 28 are fixedly connected with a lifting rod 29, the bottom end of the lifting rod 29 abuts against the edge of the elliptical disk 10, a reciprocating screw rod 30 is rotatably connected to the mounting frame 28, a sliding block 31 is connected to the reciprocating screw rod 30, the sliding block 31 is slidably connected to the mounting frame 28, and the detector 32 is installed on the sliding block 31; a lifting groove 34 is opened on one of the connecting columns 33.

[0030] In this embodiment, the detector 32 is an existing publicly available technical means for detecting marble tiles. When the reciprocating screw 30 rotates, the sliding block 31 can slide and adjust on the mounting frame 28, so that the detector 32 can be used to detect the marble tiles. When the flip frame 9 flips, due to the elliptical disk 10 fixedly connected on both sides of the flip frame 9, the elliptical disk 10 abuts against the lifting rod 29. When the flip frame 9 flips 90 degrees, the lifting rod 29 will abut against the two end parts of the elliptical disk 10, so that the lifting rod 29 is lifted, and the mounting frame 28 will slide and rise on the two connecting columns 33. The connecting columns 33 are fixedly connected to the inner wall of the body 1 to meet the installation and use of the lifting detection mechanism. When the detector 32 is about to move to one side of the mounting frame 28, the flip frame 9 is flipped 180 degrees under the transmission of the transmission mechanism. When the detector 32 moves to one side of the mounting frame 28, the flip frame 9 realizes the full flip stroke. When the detector 32 moves back and forth, the marble tiles after flipping can be detected.

[0031] See also Figure 12~Figure 15 As a further solution of the present invention, the transmission mechanism includes a second motor 20, a toothed disc 22 arranged on one side of the second motor 20, a third gear 26 connected to the toothed disc 22, and a transmission assembly connected to the second motor 20; the second motor 20 is installed on one of the brackets 6, a first gear 21 is fixedly connected to the output shaft of the second motor 20, a second gear 23 is fixedly connected to the inner ring of one side of the toothed disc 22, the first gear 21 is meshed with the second gear 23, the toothed disc 22 is rotatably connected to the bracket 6 on the same side of the second motor 20, a tooth groove 25 is fixedly connected to the outer wall of the toothed disc 22, and a contact column 24 is fixedly connected to the toothed disc 22 at one end of the tooth groove 25; the third gear 26 is meshed with the tooth groove 25, an abutment rod 27 is installed on the third gear 26, a rotating shaft on one side of the third gear 26 is rotatably connected to the bracket 6 on the same side of the toothed disc 22, the rotating shaft is fixedly connected to the central axis on one side of the flip frame 9, and the abutment rod 27 abuts against the abutment column 24.

[0032] The transmission assembly includes a transmission shaft 35, a first connecting plate 37 rotatably connected to the transmission shaft 35, and a second connecting plate 40 rotatably connected to the first connecting plate 37, the transmission shaft 35 is movably connected in the jacking groove 34; the transmission shaft 35 is fixedly connected to one end of the reciprocating screw rod 30, a second transmission wheel 36 is fixedly connected to the transmission shaft 35, a third transmission wheel 39 is rotatably provided at the rotationally connected portion between the first connecting plate 37 and the second connecting plate 40, and the third transmission wheel 39 consists of two transmission wheels; one of the third transmission wheels 39 is transmission-connected to the second transmission wheel 36 through a second belt 38, and the other transmission wheel of the third transmission wheel 39 is connected to a fourth transmission wheel 42 through a third belt 41, the fourth transmission wheel 42 is fixedly connected to the output shaft of the second motor 20, and the second connecting plate 40 is located at one end of the fourth transmission wheel 42 and is rotatably connected to the output shaft of the second motor 20.

[0033] In this embodiment, the transmission mechanism is arranged on the bracket 6, which can reduce the overall weight of the lifting detection mechanism, so that the lifting detection mechanism is more convenient for lifting operation under the resistance of the elliptical disk 10. When the second motor 20 is in action, it will drive the first gear 21 to rotate. Since the output shaft of the second motor 20 is connected to one end of the reciprocating screw rod 30 through a transmission assembly, when the second motor 20 moves, the reciprocating screw rod 30 can be rotated, so that the sliding block 31 can slide and adjust on the mounting frame 28, and the first gear 21 is meshed with the second gear 23. Since the gear ratios of the first gear 21 and the second gear 23 are different, the second gear 23 rotates one circle only after the first gear 21 rotates multiple circles. When the second gear 23 rotates one circle, the resistance column 24 will resist the end of the abutment rod 27, so that the tooth groove 25 is meshed with the third gear 26. The third gear 26 is set with tooth openings on both sides. When the tooth groove 25 is not engaged with the third gear 26, the gap will abut against the edge of the toothed disk 22 to prevent the third gear 26 from rotating when it is not engaged. When the tooth groove 25 is engaged with the third gear 26, the third gear 26 will be driven to rotate 180 degrees and then the gap will abut against the edge of the toothed disk 22 again to prevent the third gear 26 from rotating. When the tooth groove 25 is disengaged from the third gear 26, the reciprocating screw rod 30 rotates to make the sliding block 31 reciprocate on the mounting frame 28 for one cycle. By continuously performing the above-mentioned movement stroke by the second motor 20, the subsequent flipping detection of different marble tiles can be realized. When the third gear 26 is driven to rotate 180 degrees, since the third gear 26 is fixedly connected to the central axis of the flip frame 9, the flip frame 9 will be flipped and adjusted 180 degrees to meet the flipping of the marble tiles on the flip frame 9.

[0034] The method for detecting the surface and cracks of marble tiles using the integrated detection device as described above comprises the following steps: Step 1: Place the marble tiles on the conveyor belt 2 and transfer them to the machine body 1. When the marble tiles move to the position of the lifting plate 3, the piston rod of the cylinder 5 extends, and the lifting plate 3 lifts the marble tiles to the position of the turning frame 9; Step 2: The first motor 12 is actuated to rotate the bidirectional screw rod 11, and the two movable frames 13 threadedly connected to the bidirectional screw rod 11 move in a centering manner to clamp the two sides of the marble tile, and the lifting plate 3 is reset at this time; Step 3: The second motor 20 is activated to drive the detector 32 to move on the mounting frame 28, and the detector 32 scans and detects the marble tiles; Step 4: When the detector 32 moves to one side of the marble tile and continues to move, the abutment column 24 abuts against the abutment rod 27, and the tooth groove 25 meshes with the third gear 26. The toothed disc 22 rotates the third gear 26, causing the flip frame 9 to flip 180 degrees. Step 5: When the detector 32 moves back and forth for scanning and detection, the marble tiles after turning over are scanned and detected. After the detection is completed, the marble tiles are placed on the conveyor belt 2 for transmission through the lifting plate 3.

[0035] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
