[0002] Grignard metallic glaze is a glaze with unique metallic texture and rich colors, usually used in ceramic products, building decoration materials and other occasions that require decoration. After glazing the tiles, the bricks need to be tested to avoid uneven glaze distribution.

[0003] To this end, Chinese patent CN217797459U discloses a brick glazing detection device, which separates the tray and the bricks on the tray through a weighing device and measures them separately.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figure 1-Figure 6A continuous quality inspection device for Grignard metal glaze, comprising a frame 1, a detection device 2, a limiting mechanism and a pushing mechanism 4; the frame 1 is provided with a main conveying frame 11 for conveying a workpiece 6; the detection device 2 comprises a mounting platform 21 and a detection platform 22 for measuring the weight of the workpiece 6, the mounting platform 21 is arranged on the frame 1, and the detection platform 22 is arranged on the mounting platform 21; a front stopper 211 and a rear stopper 212 are telescopically arranged on the mounting platform 21, the front stopper 211 and the rear stopper 212 are respectively located on both sides of the detection platform 22, and a first elastic member 211 for controlling the reset of the front stopper 211 is arranged on the mounting platform 21. The first linear drive 213 for driving the rear block 212 to extend and retract is arranged on the mounting platform 21; the pushing mechanism 4 includes a movable rod 41 movably arranged on the mounting platform 21 and a linear driving assembly 42 for controlling the movement of the movable rod 41, and the movable rod 41 is provided with an oblique push block 411 and a fourth elastic member 412, the oblique push block 411 is slidably installed on the movable rod 41, and the two ends of the fourth elastic member 412 are respectively connected to the movable rod 41 and the oblique push block 411; in the working state, when the movable rod 41 is in the reset state, the limiting mechanism 3 limits the contraction of the front block 211.

[0038] The present invention realizes the function of limiting the remaining workpieces 6 from entering the detection platform 22 when there is a workpiece 6 on the detection platform 22 through the frame 1, the detection device 2, the auxiliary control mechanism and the pushing mechanism 4, and controls the workpiece 6 to enter and exit the detection platform 22 through the front block 211 and the rear block 212, and then limits the remaining workpieces 6 from entering the detection platform 22 through the limiting mechanism 3 when there is a workpiece 6 on the detection platform 22, so as to avoid multiple workpieces 6 from contacting the detection platform 22 at the same time and affecting the detection result, and solves the problem that the remaining workpieces 6 contact the detection platform 22 and affect the detection process during the detection of the workpiece 6. A controller for human-computer interaction is provided on the frame 1, and the front block 211 and the rear block 212 are distributed front and back along the conveying direction of the main conveying frame 11. In order to pursue special visual effects and metallic texture, the Grignard metal glaze on the workpiece 6 usually needs to use a thicker glaze layer, which will increase the overall weight of the glaze.The inspection table 22 is provided with a conveyor belt for assisting the movement of the workpiece 6. The main conveyor frame 11 is preferably a roller conveyor driven by a sprocket. The front block 211 is provided with an inclined surface. When the workpiece 6 enters the inspection table 22, the inclined surface of the front block 211 is squeezed, and the front block 211 is pushed to retract by the squeezing force. The first linear drive 213 is preferably a linear cylinder, and the first linear drive 213 is electrically connected to the controller. The limiting mechanism 3 is used to limit the retraction of the front block 211. In the working state, the workpiece 6 is glazed after the main conveyor. The frame 11 moves the workpiece 6 toward the inspection table 22. After the workpiece 6 contacts the front stopper 211 on the mounting table 21, the inclined surface of the front stopper 211 is squeezed. Due to the heavy weight of the workpiece 6, the front stopper 211 is pushed to shrink by the squeezing force. When the workpiece 6 just moves onto the mounting table 21, the workpiece 6 is pushed to move by the conveying action of the main conveying frame 11. After the workpiece 6 contacts the oblique push block 411, the oblique push block 411 is squeezed by the workpiece 6, and then the elastic force of the fourth elastic member 412 is overcome by the squeezing force to push the oblique push block 411. 11 is pressed down, and when the workpiece 6 is completely moved onto the mounting table 21, the workpiece 6 is continuously pushed to move by the conveyor belt. After the workpiece 6 completely passes through the front stopper 211, the front stopper 211 is reset under the elastic force of the first elastic member 214. After the workpiece 6 is completely moved to the detection position, the linear drive assembly 42 controls the movable rod 41 to reset. When the oblique push block 411 is separated from the workpiece 6, the oblique push block 411 is extended under the elastic force of the fourth elastic member 412, and then the movement of the workpiece 6 is restricted by the restriction mechanism 3, and the weight of the workpiece 6 is detected. , compared with the specified value input in advance, only when the difference is within the set range, it is a qualified product. After the detection is completed, the rear block 212 is driven to shrink by the first linear driver 213, and then the movable rod 41 is driven to move by the linear drive component 42, and the movable rod 41 drives the oblique push block 411 to move, and the workpiece 6 is pushed away from the detection table 22 by the pushing action of the oblique push block 411 and the conveyor belt. With the movement of the movable rod 41 and the oblique push block 411, the contraction restriction of the front block 211 by the limiting mechanism 3 is released.

[0039] Reference Figure 3 and Figure 4 : A buffer block 2121 and a third elastic member 2122 are provided on the rear block 212, and the two ends of the third elastic member 2122 are respectively connected to the buffer block 2121 and the rear baffle; in the working state, when the buffer block 2121 is in an extended state under the elastic force of the third elastic member 2122, it abuts against the detection platform 22 to limit the contraction of the rear block 212.

[0040] The present invention realizes the function of controlling the opening and closing of the limiting mechanism 3 through the buffer block 2121, the third elastic member 2122 and the pushing mechanism 4, and then cooperates with the limiting mechanism 3 to prevent the workpiece 6 from being affected by other workpieces 6 during the detection process. In the working state, the workpiece 6 is inspected after entering the detection table 22. After the detection is completed, it contacts the buffer block 2121 under the pushing action of the conveyor belt. Then, the pushing action of the workpiece 6 overcomes the elastic force of the third elastic member 2122 and pushes the buffer block 2121, so that the buffer block 2121 contacts the rear baffle. Then, the rear baffle 212 is driven downward by the first linear drive 213. At this time, the buffer block 2121 is reset by limiting the detection table 22, and then the conveyor belt and the oblique push block 411 are used to push the workpiece 6 to continue moving. In this process, the limiting Mechanism 3 continuously limits the contraction of the front stop block 211, hindering the workpiece 6 from entering the inspection table 22. After the workpiece 6 completely passes through the rear baffle, the first linear driver 213 drives the rear stop block 212 to extend. After the buffer block 2121 is separated from the inspection table 22, the buffer block 2121 is reset under the elastic force of the third elastic member 2122. After the rear stop block 212 is extended, the linear drive assembly 42 has not yet controlled the movable rod 41 and the oblique push block 411 to reset. The limiting mechanism 3 no longer limits the contraction of the front stop block 211, so that the workpiece 6 can move smoothly to the inspection table 22.

[0041] Reference Figure 5-Figure 7 : A collar 413 is rotatably provided on the movable rod 41; the linear drive assembly 42 includes a rotary driver 421 and a screw 422, the rotary driver 421 is provided on the mounting table 21, the screw 422 is rotatably provided on the mounting table 21, and the screw 422 is threadedly connected to the collar 413; a connecting mechanism 5 for limiting the rotation of the collar 413 is provided on the movable rod 41.

[0042] The present invention realizes the function of controlling the movement of the movable rod 41 through the collar 413, the rotary driver 421, the screw 422 and the connecting mechanism 5. The rotary driver 421 is preferably a servo motor, which is electrically connected to the controller; and the driving end of the rotary driver 421 and the screw 422 are sleeved with a pulley 423, and a transmission belt 424 is straddled on the pulley 423, and the two pulleys 423 are connected by the transmission belt 424; after the workpiece 6 is controlled to move to the detection position through the conveyor frame and the conveyor belt on the detection table 22, the controller sends a signal to the rotary driver 421, and the rotary driver 421 drives the screw 422 to rotate in the opposite direction after receiving the signal, and limits the rotation of the collar 413 through the connecting mechanism 5, and the screw 4 22 drives the collar 413 threadedly connected thereto to move, and the collar 413 drives the movable rod 41 to move, thereby controlling the movable rod 41 and the oblique push block 411 to reset. After the oblique push block 411 is separated from the workpiece 6, the oblique push block 411 pops up under the elastic force of the fourth elastic member 412, and then drives the screw 422 to rotate forward through the rotary driver 421, and then drives the collar 413 and the movable rod 41 to move through the screw 422, and pushes the workpiece 6 away from the inspection table 22 through the oblique push block 411 on the movable rod 41, and then the workpiece 6 is transported by the main conveying frame 11.

[0043] Reference Figure 4-Figure 8 : The limiting mechanism 3 includes a first limiting component 31, and the first limiting component 31 includes a limiting plate 311, a bracket 312 and a second elastic member 313; the limiting plate 311 is movably arranged on the mounting platform 21, and a first elastic member 214 is arranged on the limiting plate 311, and the two ends of the first elastic member 214 are respectively connected to the limiting plate 311 and the front stopper 211; the bracket 312 is connected to the mounting platform 21 through a rod, and the second elastic member 313 is arranged on the bracket 312, and the second elastic member 313 is connected to the limiting plate 311; the movable rod 41 is provided with an oblique protrusion 414 for squeezing the limiting plate 311.

[0044] The present invention realizes the function of limiting the contraction of the front stopper 211 through the limit plate 311, the bracket 312 and the second elastic member 313. In the working state, when the linear drive assembly 42 controls the movable rod 41 to reset, the rotary driver 421 drives the screw rod 422 to rotate in the opposite direction, the screw rod 422 drives the collar 413 threadedly connected thereto to move, and the collar 413 drives the movable rod 41 to move. When the oblique protrusion 414 on the movable rod 41 contacts the limit plate 311, the limit plate 311 is squeezed. The squeeze force overcomes the elastic force of the second elastic member 313 to push the limit plate 311 downward, and the limit plate 311 releases the movement restriction of the front stopper 211. When the rotary driver 421 drives the screw rod 422 to rotate forward, the screw rod 422 drives the ring 413 threadedly connected thereto to move, and then the movable rod 41 is driven to move through the ring 413. After the oblique protrusion 414 on the movable rod 41 is separated from the limit plate 311, the limit plate 311 is reset under the elastic force of the second elastic member 313, and the limit plate 311 pushes the front stop block 211 to move upward through the first elastic member 214, and limits the front stop block 211 from moving downward after the limit plate 311 abuts against the front stop block 211, thereby achieving the effect of limiting the remaining workpieces 6 from entering the detection table 22.

[0045] Reference Figure 6-Figure 8 : The limiting mechanism 3 includes a second limiting component 32, and the second limiting component 32 includes a limiting frame 321, a first connecting frame 322, a rack 323, a transmission shaft 324 and a rotating gear 325; the limiting frame 321 and the first connecting frame 322 are both movably arranged on the mounting platform 21, and the first connecting frame 322 is connected to the rear baffle; there are two racks 323, and the two racks 323 are respectively arranged on the limiting frame 321 and the first connecting frame 322; the transmission shaft 324 is rotatably arranged on the mounting platform 21; the rotating gear 325 is sleeved on the transmission shaft 324, and the rotating gear 325 is meshed and connected with the two racks 323.

[0046] The present invention realizes the function of limiting the movement of the front block 211 through the limiting frame 321, the first connecting frame 322, the rack 323, the transmission shaft 324 and the rotating gear 325, and through the movement of the rear baffle and the first connecting frame 322, the rear baffle limits the contraction of the front block 211 when it is in the retracted state. After the workpiece 6 is inspected, the workpiece 6 is pushed away from the inspection table 22 by the conveyor belt on the inspection table 22 and the pushing action of the oblique push block 411. During the pushing process, since the oblique push block 411 is no longer in the reset state, the first limiting component 31 no longer limits the contraction of the front block 211. If other workpieces 6 enter the inspection table 22, the workpiece 6 will move excessively under the pushing action of the conveyor belt, causing it to deviate from the inspection position. For this reason, a second limiting component 32 is provided. When the rear block 212 is in the retracted state, the rear block 2 The downward movement of 12 drives the first connecting frame 322 to move, and the first connecting frame 322 drives the rack 323 to move, thereby pushing the rotating gear 325 to rotate, and the rotating gear 325 drives the rack 323 on the limiting frame 321 to move upward, so that the limiting frame 321 abuts against the front block 211, and the front block 211 is limited to move downward by the limiting frame 321 until the rear baffle is reset, and the movement restriction of the front block 211 by the second limiting component 32 is released, so that the subsequent workpiece 6 can pass through the front block 211 and enter the detection table 22 for detection.

[0047] Reference Figure 6 , Figure 7 , Fig. 9 and Fig.10 : The connecting mechanism 5 includes a connecting component 51, a control component 52 and a one-way limiting component 53; the connecting component 51 includes a mounting seat 511, a docking block 512 and a fifth elastic member 513, the mounting seat 511 is arranged on the movable rod 41, the docking block 512 is slidably installed on the mounting seat 511, the two ends of the fifth elastic member 513 are respectively connected to the mounting seat 511 and the docking block 512, and a docking groove 4131 matching the docking block 512 is provided on the ring 413; the control component 52 is transmission-connected with the oblique push block 411; the one-way limiting component 53 is arranged on the movable rod 41, and in the working state, when the linear drive component 42 drives the movable rod 41 to reset, the one-way limiting component 53 limits the rotation of the ring 413.

[0048] The present invention realizes the function of limiting the movement of the collar 413 through the connection component 51, the control component 52 and the one-way limiting component 53. The control component 52 is used to control the movement of the collar 413. When the workpiece 6 is moved to the detection position on the detection table 22 through the conveyor belt and the main conveyor frame 11, the controller sends a signal to the rotary driver 421, and the rotary driver 421 drives the screw 422 to rotate in the opposite direction. At this time, the one-way limiting component 53 limits the rotation direction of the collar 413, and the screw 422 drives the collar 413 threadedly connected thereto to rotate, and then drives the movable rod 41 to reset. After the movable rod 41 is reset, the oblique push block 411 is separated from the workpiece 6, and then extends out under the elastic force of the fourth elastic member 412. In this process, the oblique push block 411 drives the control component 52, and the control component 52 controls the collar 41 3 moves toward the mounting seat 511, and then the rotating driver 421 drives the screw rod 422 to rotate. If the docking block 512 is not aligned with the docking groove 4131, the fifth elastic member 513 shrinks under the extrusion of the collar 413, and under the friction and other resistances of the movable rod 41, the screw rod 422 drives the collar 413 to rotate. When the docking groove 4131 on the collar 413 is aligned with the docking block 512, the docking block 512 is engaged with the docking groove 4131 under the elastic force of the fifth elastic member 513, and then the rotation of the collar 413 is restricted by the docking block 512 on the mounting seat 511, and the collar 413 and the movable rod 41 are driven to move by the screw rod 422.

[0049] Reference Figure 6 , Figure 7 , Fig. 9 and Fig.10 : The control component 52 includes a second connecting frame 521 and a third connecting frame 522; the second connecting frame 521 is connected to the oblique push block 411, and the second connecting frame 521 is provided with a first protrusion 5211; the third connecting frame 522 is movably arranged on the movable rod 41, and the third connecting frame 522 is provided with a sixth elastic member 5222 for controlling the third connecting frame 522 to reset, the collar 413 is rotatably connected to the third connecting frame 522, and the third connecting frame 522 is provided with a second protrusion 5221; in the working state, when the oblique push block 411 moves upward under the elastic force of the fourth elastic member 412, the oblique push block 411 drives the second connecting frame 521 to move, and the first protrusion 5211 on the second connecting frame 521 squeezes the third protrusion on the third connecting frame 522.

[0050] The present invention realizes the function of controlling the movement of the collar 413 by moving the oblique push block 411 through the second connecting frame 521 and the third connecting frame 522 . When the movable rod 41 is reset under the driving action of the linear drive assembly 42, the oblique push block 411 is no longer restricted by the workpiece 6 and extends out under the elastic force of the fourth elastic member 412, and then drives the second connecting frame 521 to move upward through the oblique push block 411, and the first protrusion 5211 on the second connecting frame 521 squeezes the second protrusion 5221 on the third connecting frame 522, and then overcomes the elastic force of the sixth elastic member 5222 through the squeezing force to push the ring 413 toward the mounting seat 511. After the workpiece 6 is pushed away from the detection table 22, when the subsequent workpiece 6 squeezes the oblique push block 411 again, the oblique push block 411 drives the second connecting frame 521 to move, and the second connecting frame 521 no longer squeezes the third connecting frame 522. The third connecting frame 522 is separated from the mounting seat 511 and reset under the magnetic force of the magnet. At this time, the rotary driver 421 can only control the movable rod 41 to reset through the screw 422, thereby ensuring the working stability and orderliness of the detection equipment.

[0052] The present invention realizes the function of one-way locking of the collar 413 through the ratchet 531, the mounting ring 532 and the stopping pawl 533, so that when the oblique push block 411 is in the pressed state, the movable rod 41 and the oblique push block 411 can be driven to reset through the screw 422; when the screw 422 rotates in the reverse direction, the ratchet 531 on the collar 413 is restricted by the stopping pawl 533 and cannot rotate in the reverse direction, so the movable rod 41 and the oblique push block 411 can be reset by driving the rotary driver 421.
