Description

Technical Field

[0001] This invention relates to the field of testing equipment, and in particular to a surface defect testing device and a method for detecting defects in traditional Chinese medicine decoction pieces. Background Technology

[0002] Visual inspection equipment is an automated inspection system based on computer vision technology. It typically consists of an industrial camera, optical lens, light source, image acquisition card, and core image processing and analysis software. Its working principle involves acquiring high-quality images of the target object, then using algorithms to extract, analyze, and judge features within the image, ultimately achieving non-contact, high-precision, and high-efficiency automated inspection. In the field of traditional Chinese medicine (TCM) inspection, visual inspection equipment plays an increasingly important role, with applications covering multiple stages: In the raw material acceptance stage of TCM materials, it can quickly identify the type of medicinal material, detect foreign objects, assess whether the size and shape of the medicinal material meet grading standards, and analyze its color and surface texture to assist in judging freshness or mold; in the production process of TCM decoction pieces, visual inspection equipment can monitor the uniformity of the cut dimensions and the integrity of the shape of the decoction pieces online, identify and remove unqualified products such as black pieces, mushy pieces, and discolored pieces, and check the purity of the decoction pieces.

[0003] Chinese patent application CN115060732A discloses a visual inspection device, comprising: a track assembly for transporting a product to be inspected; a light-shielding assembly disposed on the track assembly, the light-shielding assembly having a clearance notch for the product to be inspected to enter and exit, the clearance notch being located above the track assembly; an image acquisition mechanism disposed within the light-shielding assembly for acquiring appearance information of the product to be inspected from at least three dimensions; and a sealing assembly movably connected to the light-shielding assembly, the sealing assembly having a first state and a second state. In the first state, the sealing assembly abuts against the track assembly to cover the clearance notch; in the second state, the sealing assembly moves away from the track assembly to expose the clearance notch. This effectively solves the technical problem of poor reliability of product appearance inspection results caused by light pollution in traditional visual inspection technologies. Chinese patent application CN111337496A discloses a sorting device and method for Chinese medicinal herbs, including a robotic arm, a camera, a controller, a support, a computer, and a discharge box. The discharge box and camera are mounted on the support. The camera is connected to the USB port on the computer host via a data cable. The network port on the computer host is connected to the network port on the controller via a network cable. The signal output terminal of the controller is connected to the signal input port of the robotic arm via a cable. The device acquires images and uses the computer to identify moldy medicinal herbs to obtain the centroid coordinates of the moldy herbs. The robotic arm, with the centroid coordinates input, then grabs the moldy medicinal herbs and places them into the discharge box to achieve the identification and sorting of moldy medicinal herbs. This method has high work efficiency, saves labor, and avoids the problems of missed and misjudged selection.

[0004] The aforementioned patents and prior art also have the following defects: Some medicinal materials need to be sliced ​​when making medicinal slices. After slicing, they need to be tested and unqualified materials need to be removed. Manual selection is inefficient. When using visual recognition, the sliced ​​materials are easy to overlap, making the materials underneath unable to be identified. The recognition accuracy is low and the adaptability is poor.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Reference Figures 1-11 The surface defect detection device shown includes a vibration transmission component 1, a detection transmission component 2, and a vision detection component 3. The vision detection component 3 includes a CCD optical sensor 31, a supplementary light 32, and a detection controller. The CCD optical sensor 31 is connected to the detection controller. The detection transmission component 2 includes a main transmission unit 21 and a secondary transmission unit 22. The vision detection component 3 is disposed on the main transmission unit 21 and the secondary transmission unit 22. The main transmission unit 21 and the secondary transmission unit 22 are provided with transfer components 4. The vibration transmission component 1 can transmit materials to the main transmission unit 21, and the transfer components 4 can transfer materials stacked on the main transmission unit 21 that are closer to the top to the secondary transmission unit 22.

[0023] Vibration transmission component 1 transmits materials to main transmission unit 21. Transfer component 4 transfers materials near the top of the stacked materials on main transmission unit 21 to secondary transmission unit 22. The CCD optical sensor 31 of vision inspection component 3 works with the detection controller to detect materials on main transmission unit 21 and secondary transmission unit 22. By setting up vibration transmission component 1, detection transmission component 2 and vision inspection component 3, the transmission and detection of materials are integrated. Transfer component 4 can effectively separate stacked materials to prevent the materials below from being unable to be detected due to material stacking, thus ensuring the accuracy of subsequent detection.

[0024] Example 2, refer to Figures 1-11 The difference from the above embodiment is that the transfer component 4 includes an electric slide unit 41, an adsorption cylinder 42, and an adsorption plate 43. The adsorption cylinder 42 is mounted on the electric slide unit 41, and the electric slide unit 41 can drive the adsorption cylinder 42 to move between the main transfer unit 21 and the auxiliary transfer unit 22. The adsorption plate 43 is fixedly installed at the output end of the adsorption cylinder 42. An adsorption cavity is opened in the adsorption plate 43, and the adsorption cavity is connected to the adsorption vacuum machine through an adsorption hose. Several adsorption holes are opened at the bottom of the adsorption plate 43.

[0025] When the material moves to the position of the transfer component 4, the adsorption cylinder 42 drives the adsorption plate 43 to descend. The adsorption holes at the bottom of the adsorption plate 43 are connected to the adsorption vacuum machine through the adsorption cavity and adsorption hose to form a negative pressure, adsorbing the material near the top of the stacked material on the main transfer unit 21. Then, the electric slide unit 41 drives the adsorption cylinder 42 and the adsorption plate 43 to move above the secondary transfer unit 22. The adsorption vacuum machine stops working, and the material falls into the secondary transfer unit 22. The material is transferred by adsorption to avoid mechanical damage to the material. The electric slide unit 41 realizes the precise movement of the adsorption cylinder 42 between the main transfer unit 21 and the secondary transfer unit 22.

[0026] The descent distance of the adsorption plate 43 is set to be greater than the thickness of a single herb slice. Since the total thickness of the stacked herbs below exceeds the set descent distance, the adsorption plate 43 contacts the topmost slice of the stacked herbs, and the adsorption holes generate negative pressure to adsorb the slice of herbs, thus separating the stacked herbs.

[0027] Example 3, referring to Figures 1-11The difference from the above embodiment is that the electric slide unit 41 includes a support frame, a drive motor 411, a drive screw 412, a limiting rail 413, and a moving block 414. The drive motor 411 is fixedly mounted on the support frame, the drive screw 412 is rotatably connected to the support frame, the drive screw 412 is fixedly mounted on the output end of the drive motor 411, the limiting rail 413 is fixedly mounted on the support frame, the moving block 414 is sleeved on the drive screw 412 and threadedly connected to the drive screw 412, a limiting groove is formed on the moving block 414, the limiting rail 413 is set in the limiting groove, and the adsorption cylinder 42 is fixedly mounted on the moving block 414.

[0028] The drive motor 411 drives the drive screw 412 to rotate. Since the moving block 414 is threadedly connected to the drive screw 412 and is limited by the limiting slide groove and the limiting track 413, the moving block 414 moves linearly along the limiting track 413, thereby driving the adsorption cylinder 42 fixed on the moving block 414 to move, realizing the smooth movement and precise positioning of the moving block 414. The cooperation of the limiting track 413 and the limiting slide groove ensures the straightness and stability of the movement of the moving block 414, thereby ensuring the smooth and reliable material transfer process driven by the adsorption cylinder 42.

[0029] Example 4, refer to Figures 1-11 The difference from the above embodiment is that the main transmission unit 21 and the auxiliary transmission unit 22 are further provided with a picking assembly 5. The picking assembly 5 includes a flip motor 51, a flip shaft, a flip plate 52, several picking units 53, and a picking transmission unit 54. The picking unit 53 includes a picking cylinder 531, a picking piston rod 532, a return spring 533, and a picking block 534. The flip shaft is fixedly installed at the output end of the flip motor 51, and the flip plate 52 is fixedly installed on the flip shaft. The cylinder 531 is fixedly mounted on the flip plate 52. The picking piston rod 532 is slidably fitted inside the picking cylinder 531. The picking block 534 is fixedly mounted on the picking piston rod 532. One end of the return spring 533 is fixedly mounted on the picking block 534, and the other end of the return spring 533 is fixedly mounted on the picking cylinder 531. The picking block 534 has a picking cavity inside and a picking hole at the bottom. The picking transmission unit 54 is located on one side of the picking block 534.

[0030] When the materials on the main transmission unit 21 and the auxiliary transmission unit 22 move to the position of the picking assembly 5, the picking cylinder 531 drives the picking piston rod 532 to lower the picking block 534. The picking hole at the bottom of the picking block 534 forms a negative pressure through the picking cavity to adsorb unqualified materials. Then the picking cylinder 531 stops driving, and the reset spring 533 pulls the picking piston rod 532 and the picking block 534 to rise. The flipping motor 51 drives the flipping shaft to rotate the flipping plate 52, moving the picking block 534 above the picking transmission unit 54. The negative pressure in the picking hole stops, and the materials fall into the picking transmission unit 54. Several picking units 53 can pick multiple materials at the same time, improving the picking efficiency. The flipping motor 51 drives the flipping plate 52 to rotate to realize the transfer of materials. The picking transmission unit 54 promptly transfers away unqualified materials to ensure the continuous operation of the equipment.

[0031] A sorting negative pressure pipe is fixedly installed on the sorting block 534, and the sorting negative pressure pipe is connected to the sorting vacuum machine. A pushing air pipe is fixedly installed on the sorting cylinder 531, and the pushing air pipe is connected to the sorting air compressor. An electromagnetic air valve is installed inside the pushing air pipe.

[0032] The vacuum sorting machine provides negative pressure to the sorting cavity in the sorting block 534 through the sorting negative pressure pipe, so that the sorting hole generates an adsorption force to adsorb the material. The sorting air compressor pushes the air pipe to introduce compressed gas into the sorting cylinder 531. The electromagnetic air valve controls the opening and closing of the gas in the pushing air pipe, thereby controlling the extension and retraction of the sorting piston rod 532.

[0033] Example 5, refer to Figures 1-11 The difference from the above embodiment is that the picking and conveying unit 54 includes a picking and fixing frame 541, a picking and conveying motor 542, a plurality of picking and conveying shafts and a picking and conveying belt 543. The picking and conveying motor 542 is fixedly installed on the picking and fixing frame 541, and the plurality of picking and conveying shafts are rotatably connected inside the picking and fixing frame 541. One of the picking and conveying shafts is fixedly installed on the output end of the picking and conveying motor 542, and the picking and conveying belt 543 is connected to the plurality of picking and conveying shafts.

[0034] The picking conveyor motor 542 drives the picking conveyor shaft connected to it to rotate, which in turn drives other picking conveyor shafts to rotate through the picking conveyor belt 543, causing the picking conveyor belt 543 to move continuously and transport the unqualified materials that fall on it to the designated position.

[0035] Example 6, refer to Figures 1-11The difference from the above embodiment is that the vibration transmission assembly 1 includes a fixed base 11, a vibrator 12, several vibration units 13, and a vibration transmission unit 14. The vibration transmission unit 14 includes a vibration fixing frame 141, a vibration transmission motor 142, several vibration transmission shafts, and a vibration transmission belt 143. The vibration transmission motor 142 is fixedly mounted on the vibration fixing frame 141, and several vibration transmission shafts are rotatably connected inside the vibration fixing frame 141. One of the vibration transmission shafts is fixedly mounted on the output end of the vibration transmission motor 142. The vibration transmission belt 143 is connected to several vibration transmission shafts. The vibration unit 13 includes a connecting rod 131, a lower fixed block, an upper fixed block, and a vibration spring 132. One end of the connecting rod 131 is rotatably connected to the fixed base 11, and the other end of the connecting rod 131 is rotatably connected to the vibration fixing frame 141. The lower fixed block is fixedly mounted on the fixed base 11, the upper fixed block is fixedly mounted on the vibration fixing frame 141, the vibration spring 132 is fixedly mounted between the lower fixed block and the upper fixed block, and the vibrator 12 is fixedly mounted on the vibration fixing frame 141.

[0036] The vibrator 12 drives the vibrating fixed frame 141 to vibrate. The vibrating fixed frame 141 vibrates on the fixed base 11 through the connecting rod 131 of the vibrating unit 13, the lower fixed block, the upper fixed block, and the vibrating spring 132. At the same time, the vibrating transmission motor 142 drives the vibrating transmission shaft to rotate, which moves the vibrating transmission belt 143. The material placed on the vibrating transmission belt 143 is spread out under the combined action of vibration and transmission. The connecting rod 131 and the vibrating spring 132 of the vibrating unit 13 cooperate to make the vibration of the vibrating fixed frame 141 stable and have a certain buffering effect, so as to avoid damage to the material by violent vibration. The vibrating transmission belt 143 transmits while vibrating, which can effectively prevent the material from accumulating and make the material distributed in a horizontal state, which is convenient for subsequent testing.

[0037] Example 7, referring to Figures 1-11 The difference from the above embodiment is that a blocking component 6 is provided on the vibration transmission belt 143. The blocking component 6 includes a blocking plate 61, a connecting block 62, a blocking screw 63, a rotating knob, and a mounting block. The mounting block is fixedly installed on the vibration fixing frame 141, the blocking screw 63 rotates on the mounting block, the rotating knob is fixedly installed on the blocking screw 63, the connecting block 62 is sleeved on the blocking screw 63 and threadedly connected to the blocking screw 63, and the blocking plate 61 is fixedly installed on the connecting block 62. The blocking plate 61 is located above the vibration transmission belt 143.

[0038] Rotating the knob drives the blocking screw 63 to rotate. Since the connecting block 62 is threadedly connected to the blocking screw 63 and is limited by the mounting block, the connecting block 62 drives the blocking plate 61 to move up and down, adjusting the distance between the blocking plate 61 and the vibrating conveyor belt 143. The blocking plate 61 blocks excess material on the vibrating conveyor belt 143, allowing the material to continuously vibrate and spread on the vibrating conveyor belt 143 before falling into the main conveying unit 21 through the gap below. The height of the blocking plate 61 can be easily adjusted by rotating the knob to adapt to the conveying needs of materials of different specifications. The blocking plate 61 can effectively control the flow and distribution of materials, allowing the materials sufficient time to vibrate and spread.

[0039] The main transmission unit 21 includes a main transmission fixed frame 211, a main transmission motor 212, several main transmission shafts, and a main transmission belt 213. The main transmission motor 212 is fixedly mounted on the main transmission fixed frame 211, and several main transmission shafts are rotatably connected to the main transmission fixed frame 211. One of the main transmission shafts is fixedly mounted on the output end of the main transmission motor 212. The main transmission belt 213 is connected to several main transmission shafts. A rubber strip 7 is provided between the vibration transmission belt 143 and the main transmission belt 213, and the rubber strip 7 is fixedly mounted on the vibration fixed frame 141.

[0040] The main transmission motor 212 drives the main transmission shaft to rotate, which in turn moves the main transmission belt 213 to transport the material that falls from the vibrating transmission belt 143 through the rubber strip 7 forward. The rubber strip 7 acts as a transition to prevent the material from falling between the vibrating transmission belt 143 and the main transmission belt 213. In addition, the rubber strip 7 has a certain deformation capacity to adapt to the vibration of the vibrating transmission belt 143.

[0041] The secondary transmission unit 22 includes a secondary transmission fixed frame 221, a secondary transmission motor 222, several secondary transmission shafts, and a secondary transmission belt 223. The secondary transmission motor 222 is fixedly mounted on the secondary transmission fixed frame 221, and several secondary transmission shafts are rotatably connected to the secondary transmission fixed frame 221. One of the secondary transmission shafts is fixedly mounted on the output end of the secondary transmission motor 222, and the secondary transmission belt 223 is connected to several secondary transmission shafts.

[0042] The auxiliary transmission motor 222 drives the auxiliary transmission shaft to rotate, which in turn moves the auxiliary transmission belt 223 to receive the material transferred from the transfer component 4 and transport it forward. After the material is inspected by the vision inspection component 3, it enters the picking component 5, enabling the material to be transferred, inspected, and picked in an orderly manner.

[0043] Example 8, referring to Figures 1-11The difference from the above embodiment is that a fixed housing 8 is fixedly installed on the fixed base 11, a support frame is fixedly installed on the fixed housing 8, the supplementary light 32 includes a light box, a light diffuser plate and several LED beads, the LED beads are fixedly installed inside the light box, the light diffuser plate is installed at the bottom of the light box, the light box is fixedly installed on the fixed housing 8, the CCD optical sensor 31 is fixedly installed with a fixed rod, the fixed rod is fixedly installed on the fixed housing 8, the flip motor 51 is fixedly installed on the fixed housing 8, the flip shaft is rotatably connected to the fixed housing 8, and the picking fixed frame 541, the main transmission fixed frame 211 and the auxiliary transmission fixed frame 221 are all fixedly installed on the fixed housing 8.

[0044] As another preferred embodiment, it has multiple picking components 5 and transfer components 4 to improve efficiency.

[0045] A method for detecting defects in traditional Chinese medicine decoction pieces, using the aforementioned surface defect detection equipment, includes the following steps: Place the sliced ​​medicinal materials on the vibration transmission component 1; Vibration transmission component 1 transmits the medicinal materials to main transmission unit 21; The transfer component 4 transfers the medicinal materials stacked on the main transfer unit 21 from the top to the secondary transfer unit 22, thus separating the stacked medicinal materials. The CCD optical sensor 31 of the vision inspection component 3 works in conjunction with the inspection controller to inspect the medicinal materials on the main transmission unit 21 and the secondary transmission unit 22.

[0046] Working principle of the invention: The sliced ​​medicinal materials are placed on the vibrating conveyor belt 143. The vibrator 12 drives the vibrating fixing frame 141 to vibrate, which in turn drives the vibrating conveyor belt 143 to vibrate. The vibrating conveyor belt 143 then vibrates the medicinal materials, spreading them out on the belt to prevent accumulation and ensuring the sliced ​​materials are horizontal for easy subsequent inspection. The vibrating conveyor motor 142 drives the vibrating conveyor shaft to rotate, which in turn moves the vibrating conveyor belt 143, which in turn moves the medicinal materials. The materials fall through the gap below the baffle plate 61 onto the main conveyor belt 213. The baffle plate 61 blocks most of the materials, allowing them to continuously vibrate and spread out on the vibrating conveyor belt 143. This process can be repeated when different sizes of the sliced ​​medicinal materials require different handling methods. When adjusting the distance between the baffle plate 61 and the vibrating transmission belt 143, operate the rotary knob. Rotating the knob drives the baffle screw 63 to rotate, and the connecting block 62 moves on the baffle screw 63. The connecting block 62 drives the baffle plate 61 to move, thereby adjusting the distance between the baffle plate 61 and the vibrating transmission belt 143. The main transmission motor 212 drives the main transmission shaft to rotate, and the main transmission shaft drives the main transmission belt 213 to move. The main transmission belt 213 drives the medicinal materials to move. When the medicinal materials move to the position of the transfer component 4, the adsorption cylinder 42 drives the adsorption plate 43 to descend a specified distance. Since the thickness of the medicinal material slices is uniform, while the thickness of the stacked medicinal materials is thicker, the adsorption plate 43 abuts against the medicinal materials near the top of the stacked medicinal materials. The adsorption holes adsorb the medicinal materials. The adsorption cylinder 42 drives the adsorption plate 43 to descend. As the medicinal materials rise, the drive motor 411 drives the drive screw 412 to rotate, and the moving block 414 moves on the drive screw 412. The moving block 414 drives the adsorption cylinder 42 and the medicinal materials to move. When the medicinal materials are moved above the secondary conveyor belt 223, the adsorption cylinder 42 drives the adsorption plate 43 and the medicinal materials to descend, stopping the negative pressure in the adsorption holes. The medicinal materials fall onto the secondary conveyor belt 223, and the secondary conveyor motor 222 drives the secondary conveyor shaft to rotate. The secondary conveyor shaft drives the secondary conveyor belt 223 to move, and the secondary conveyor belt 223 drives the medicinal materials to move. The supplementary light 32 provides supplementary light to the medicinal materials on the main conveyor belt 213 and the secondary conveyor belt 223. The CCD optical sensor 31 detects the medicinal materials. The main conveyor belt 213 and the secondary conveyor belt 223 continue to drive the medicinal materials to move. When they move to the position of the picking component 5... When the non-conforming medicinal material is in contact with the picking cylinder 531, compressed gas is introduced into it. The picking piston rod 532 moves downward, causing the picking block 534 to move downward. The picking block 534 comes into contact with the non-conforming medicinal material, creating a negative pressure in the picking hole to adsorb the non-conforming medicinal material. Afterward, the supply of compressed gas to the picking cylinder 531 is stopped, and the return spring 533 causes the picking piston rod 532 and the picking block 534 to rise. The flipping motor 51 drives the flipping shaft to rotate, which in turn drives the flipping plate 52 to rotate. The flipping plate 52 causes the picking cylinder 531, the picking piston rod 532, the picking block 534, and the non-conforming medicinal material to move in a circular motion. When the medicinal material moves above the picking conveyor belt 543, the negative pressure in the picking hole disappears, and the medicinal material falls onto the picking conveyor belt 543.The picking and conveying motor 542 drives the picking and conveying shaft to rotate, which in turn drives the picking and conveying belt 543 to move. The picking and conveying belt 543 then transports and discharges the substandard medicinal materials.

[0047] The vibration transmission component 1 achieves uniform spreading of medicinal materials, and with the adjustable blocking component 6, it can adapt to the processing needs of medicinal materials of different specifications, improving the stability and adaptability of material transmission; the transfer component 4 uses adsorption and electric sliding table unit 41 to achieve precise material transfer, prevent medicinal materials from overlapping, and improve the detection effect; the picking component 5 realizes automatic picking and transmission of unqualified medicinal materials through picking unit 53 and picking transmission unit 54, reducing manual intervention and improving picking efficiency.
