Description

Technical Field

[0001] This disclosure relates to the field of industrial automation, and more specifically, to an end-face defect detection device. Background Technology

[0002] Currently, the end face inspection of small cylindrical products (such as soft magnetic components with a diameter of about 2mm) is generally carried out manually by visual inspection. The types of end face defects that need to be inspected include end face dimensional deviations, end face appearance defects (such as chipped corners, incomplete chamfers, surface dirt, etc.), and foreign objects in the end face internal holes.

[0003] The manual visual inspection method requires operators to observe and subjectively judge the end face of each product with the help of an electron microscope. This method is not only inefficient and difficult to meet the needs of mass production, but also susceptible to human factors (such as visual fatigue), resulting in poor inspection accuracy and the risk of missed detections or misjudgments.

[0025] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0026] Example Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the end-face defect detection device 100 provided in this embodiment.

[0027] The end-face defect detection device 100 provided in this embodiment is used for end-face inspection of small cylindrical soft magnetic components. Specifically, the device includes a base plate 110, a turntable mechanism 120, a feeding mechanism 130, an inspection mechanism 140, and a discharging mechanism 150. The turntable mechanism 120, feeding mechanism 130, inspection mechanism 140, and discharging mechanism 150 are all mounted on the base plate 110. The turntable mechanism 120 can cyclically rotate between the feeding station, the inspection station, and the discharging station. The feeding mechanism 130 is used to feed the product to be inspected to the turntable mechanism 120 at the feeding station. The inspection mechanism 140 is used to inspect the end-face defects of the product to be inspected at the inspection station. The discharging mechanism 150 is used to classify and unload the product to be inspected at the discharging station based on the inspection results of the inspection mechanism 140.

[0028] To further improve detection efficiency, the end face defect detection equipment 100 provided in this embodiment has two turntable mechanisms 120, two feeding mechanisms 130, two detection mechanisms 140 and two unloading mechanisms 150, which are combined in a one-to-one correspondence to form two detection units on the base plate 110. The two detection units can operate simultaneously.

[0029] In this embodiment, for soft magnetic components, the detection results of the detection mechanism 140 include four types: end face dimensional deviation, end face appearance defects, foreign matter in the end face internal hole, and qualified products. The unloading mechanism 150 classifies and unloads the products to be inspected according to the four types of detection results. For example, if the detection mechanism 140 detects that the end face defect of a product to be inspected is an end face appearance defect, the unloading mechanism 150 unloads the product to be inspected at the unloading station into the end face appearance defect category for collection.

[0030] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 2 The diagram shown is a schematic representation of the turntable mechanism 120 from one perspective. Figure 3 The diagram shown is a schematic representation of the turntable mechanism 120 from another perspective. Figure 4 The diagram shown is a structural schematic of the turntable mechanism 120 from another perspective.

[0031] In this embodiment, the turntable mechanism 120 includes a mounting base 121, a driving component 122, and an acupoint turntable 123. The mounting base 121 is erected on the base plate 110. The driving component 122 is mounted on the mounting base 121 and is connected to the acupoint turntable 123 for transmission. The plane of the acupoint turntable 123 is perpendicular to the base plate 110, and multiple acupoint holes 124 for loading products to be inspected are provided through the acupoint turntable 123. The multiple acupoint holes 124 are arranged sequentially at intervals in the circumferential direction of the acupoint turntable 123. The driving component 122 is used to drive the acupoint turntable 123 to rotate so that each acupoint hole 124 passes sequentially through the loading station, the inspection station, and the unloading station.

[0032] Understandably, for small cylindrical products, the ends are prone to deformation or breakage due to their small cross-sectional area and stress concentration under slightly larger forces. In this embodiment, the plane of the acupoint turntable 123 is perpendicular to the base plate 110, and its acupoint holes 124 extend approximately horizontally. When the product to be inspected is loaded into the acupoint holes 124, the intact sidewalls of the product are supported, preventing deformation or breakage at its ends due to stress. Furthermore, the product to be inspected can be fully exposed at both ends in a stable state, ensuring the accuracy of end-face inspection.

[0033] In fact, the mounting base 121 includes a mounting plate 1211 and two support plates 1212. The mounting plate 1211 is set on the base plate 110, and the two support plates 1212 are spaced apart and opposite to each other on the mounting plate 1211, with a reinforcing rod 1213 connecting the two support plates 1212. A reducer connecting plate 1214 is fixed to the top of the two support plates 1212, and a hollow reducer 1215 is mounted on the reducer connecting plate 1214. The driving component 122 is actually a motor, and its shaft is connected to the input end of the hollow reducer 1215. The output end of the central reducer is connected to the acupoint turntable 123, that is, the driving component 122 is connected to the acupoint turntable 123 through the hollow reducer 1215.

[0034] In practical applications, as the drive unit 122 rotates the acupoint turntable 123, multiple acupoint holes 124 around the acupoint turntable 123 sequentially pass through the loading station, inspection station, and unloading station. For any acupoint hole 124, upon reaching the loading station, the loading mechanism 130 loads the product to be inspected into the acupoint hole 124, i.e., the product to be inspected is loaded into the acupoint hole 124. Subsequently, when the acupoint hole 124 reaches the inspection station, the inspection mechanism 140 performs end face inspection on both ends of the product to be inspected through both ends of the acupoint hole 124 to obtain the inspection results. After the inspection is completed, when the product to be inspected reaches the unloading station, the unloading mechanism 150 sorts and unloads the product to be inspected according to the inspection results of the inspection structure.

[0035] To achieve rapid and reliable loading of products for inspection and to limit the movement of products during transportation, the turntable mechanism 120 provided in this embodiment also includes a back plate 125. The back plate 125 is fixedly mounted on the mounting base 121, and is positioned opposite to one side of the acupoint turntable 123. Specifically, a plurality of mounting posts 1216 protrude from the reducer connecting plate 1214, and the plurality of mounting posts 1216 are fixedly connected to the back plate 125.

[0036] The feeding mechanism 130 is located on the side of the acupoint turntable 123 away from the back plate 125. The back plate 125 is provided with a feeding magnet 126 at the position corresponding to the feeding station. The feeding magnet 126 is used to magnetically attract the product to be inspected output by the feeding mechanism 130 at the feeding station, so that the product to be inspected can be inserted into the acupoint hole 124.

[0037] In practical applications, the product to be inspected output by the feeding mechanism 130 is located at the feeding station, on the side of the acupoint turntable 123 away from the back plate 125. When the acupoint turntable 123 rotates until a certain acupoint hole 124 is axially aligned with the product to be inspected and the feeding magnet 126, the product to be inspected quickly detaches from the feeding mechanism 130 under the magnetic attraction of the feeding magnet 126 and passes through the acupoint hole 124, thus completing the feeding of the product to be inspected. The hole wall of the acupoint hole 124 provides support and circumferential restraint for the product to be inspected, and the back plate 125 provides a stop restraint on the end of the product to be inspected away from the feeding mechanism 130.

[0038] In order to achieve the stop and limit at the other end of the product to be inspected, the turntable mechanism 120 provided in this embodiment also includes a glass guard plate 127. The glass guard plate 127 is slidably disposed on the mounting base 121 and is disposed opposite to the side of the acupoint turntable 123 near the feeding mechanism 130. The distance between the glass guard plate 127 and the acupoint turntable 123 is adjustable, and the glass guard plate 127 is provided with a feeding avoidance part 1271 at the position corresponding to the feeding station to expose the end of the acupoint hole 124 near the feeding mechanism 130.

[0039] Specifically, a support shaft 1217 is also provided on the reducer connecting plate 1214. The support shaft 1217 coaxially passes through the back plate 125 and the acupoint turntable 123. A shaft fixing block 1218 is slidably installed on the support shaft 1217. The glass guard plate 127 is fixedly sleeved on the shaft fixing block 1218.

[0040] Because the glass guard plate 127 is provided with a feeding clearance part 1271 at the position corresponding to the feeding station, the product to be inspected output by the feeding mechanism 130 can smoothly enter the cavity hole 124 through the feeding clearance part 1271. As the cavity turntable 123 continues to rotate after feeding, the cavity hole 124 carries the product to be inspected away from the feeding station and moves towards the inspection station. After leaving the feeding station, the product to be inspected enters the cavity formed between the back plate 125 and the glass guard plate 127, and the glass guard plate 127 stops and limits the end of the product to be inspected that is away from the back plate 125.

[0041] In practical applications, the position of the shaft fixing block 1218 on the support shaft 1217 is adjusted according to the model of the product to be inspected, that is, the distance between the glass guard plate 127 and the acupoint turntable 123 is adjusted to accommodate the length dimensions of products to be inspected of different specifications.

[0042] Furthermore, to avoid the detection mechanism 140, the back plate 125 and the glass protective plate 127 in this embodiment are each provided with a detection avoidance part 1272 at the position corresponding to the detection station, so that the opposite ends of the acupoint hole 124 are exposed at the detection station. Similarly, to avoid the unloading mechanism 150, the back plate 125 and the glass protective plate 127 in this embodiment are each provided with a unloading avoidance part 1273 at the position corresponding to the unloading station, so that the opposite ends of the acupoint hole 124 are exposed at the unloading station.

[0043] Understandably, when the product to be inspected is in a position other than the loading station, inspection station, and unloading station, both ends of the product are stopped by the back plate 125 and the glass guard plate 127 respectively, so as to ensure the stability of the product to be inspected during transportation and prevent the product to be inspected from accidentally falling out of the cavity hole 124.

[0044] Please refer to the following: Figure 5 , Figure 5 As shown Figure 1 An enlarged schematic diagram of region A in the middle.

[0045] The feeding mechanism 130 provided in this embodiment includes a vibrating feeding plate 131 and a feeding transition mechanism 132. The feeding transition mechanism 132 includes a track block 1321 and an adjustment component. The adjustment component is disposed on the base plate 110, and the track block 1321 is connected to the adjustment component. The adjustment component is configured to adjust the position of the track block 1321 in space. At least one feeding groove 1322 is provided on the track block 1321, and the feeding groove 1322 is used to guide the product to be inspected output by the vibrating feeding plate 131 into the cavity hole 124.

[0046] In practical applications, the position of the track block 1321 is adjusted by adjusting the components so that the output end of the vibrating feed plate 131 is aligned with one end of a feed trough 1322 on the track block 1321. During the operation of the vibrating feed plate 131, multiple products to be inspected are continuously and directionally conveyed into the feed trough 1322, with the other end of the feed trough 1322 positioned at the loading station. It can be understood that as the vibrating feed plate 131 continues to operate, the products to be inspected at the rear in the feed trough 1322 push the products to be inspected at the front, gradually approaching the acupoint turntable 123.

[0047] When the acupoint turntable 123 rotates to a certain acupoint hole 124 aligns with the feeding trough 1322 at the feeding station, the product to be inspected at the end of the feeding trough 1322 away from the vibrating feeding plate 131 is quickly removed from the feeding trough 1322 by the magnetic attraction of the feeding magnet 126 and passes into the acupoint hole 124, thus completing the feeding.

[0048] Please refer to the following: Figure 6 , Figure 6 The diagram shown is a schematic diagram of the feeding transition mechanism 132.

[0049] In this embodiment, the adjustment assembly includes a sliding base 1323, a lifting block 1324, and a transition plate 1325. The sliding base 1323 is slidably disposed on the base plate 110 and can slide relative to the base plate 110 in a first horizontal direction. The lifting block 1324 is slidably disposed on the sliding base 1323 and can move relative to the sliding base 1323 in a vertical direction. The transition plate 1325 is connected to the lifting block 1324, and a track block 1321 is slidably disposed on the transition plate 1325 and can slide relative to the transition plate 1325 in a second horizontal direction, the second horizontal direction forming an angle with the first horizontal direction.

[0050] In fact, Figure 6 The direction indicated by the X arrow is the first horizontal direction, which is actually the direction that is closer to or farther from the acupoint turntable 123. In this embodiment, the feed trough 1322 extends in the first horizontal direction. Figure 6 The direction indicated by the Y-arrow in the figure is the second horizontal direction, which is perpendicular to the first horizontal direction. In this embodiment, there are two feed troughs 1322, and the two feed troughs 1322 are arranged at intervals in the second horizontal direction. Figure 6 The direction indicated by the Z-arrow is the vertical direction, perpendicular to the base plate 110.

[0051] In practical applications, by adjusting the position of the sliding base 1323 on the base plate 110 in the first horizontal direction, adjusting the height of the lifting block 1324 on the sliding base 1323, and adjusting the position of the track block 1321 on the transition plate 1325 in the second horizontal direction, the position of the track block 1321 in space can be adjusted to ensure that one end of the feed trough 1322 is aligned with the output end of the vibrating feed plate 131, and the other end is located on the movement path of multiple acupoint holes 124 at the feeding station.

[0052] Understandably, one of the two feed troughs 1322 conveys the product to be inspected between the vibrating feed plate 131 and the acupoint hole 124, while the other feed trough 1322 serves as a backup. If the current feed trough 1322 conveying the product to be inspected suffers surface damage, the position of the track block 1321 on the transition plate 1325 is adjusted so that the backup feed trough 1322 aligns with the output end of the vibrating feed plate 131, replacing the feed trough 1322 with surface damage. This ensures normal feeding of the product to be inspected and prevents damage to the product.

[0053] The feeding mechanism 130 provided in this embodiment also includes a dust removal device 133, an origin detection device 134, a material shortage detection device 135, and a positioning detection device 136. The dust removal device 133 is used to blow air into the feeding trough 1322 to remove dust adhering to the surface of the product to be inspected. The origin detection device 134 is installed on one side of the sliding base 1323 and can be height adjusted to detect the alignment status of the feeding trough 1322 with any acupoint hole 124. The material shortage detection device 135 is installed on one side of the transition plate 1325 to detect whether there is a product to be inspected in the feeding trough 1322. The positioning detection device 136 is installed on one side of the lifting block 1324 to detect whether the product to be inspected has entered the acupoint hole 124 to the preset loading position.

[0054] In fact, the end-face defect detection device 100 provided in this embodiment also includes a controller, which is communicatively connected to at least the drive unit 122, the origin detection device 134, the material shortage detection device 135, and the positioning detection device 136. In practical applications, the controller controls the drive unit 122 to operate based on the detection result of the origin detection device 134, so as to achieve rapid reset of the acupoint turntable 123, improve the alignment efficiency of the acupoint hole 124 and the feed groove 1322, and thus improve the detection efficiency.

[0055] When the material shortage detection device 135 detects that there is no product to be inspected in the feed trough 1322, the controller sends a replenishment signal to remind the operator to add the product to be inspected to the vibrating feed plate 131. When the arrival detection device 136 detects that the product to be inspected has not reached the preset loading position, the controller sends a fault signal to remind the operator to troubleshoot the fault. In this embodiment, the product to be inspected is set to reach the loading position when it passes through the acupoint hole 124 and contacts the back plate 125.

[0056] Please refer to the following: Figure 7 , Figure 7 The diagram shown is a structural schematic of the detection mechanism 140.

[0057] The testing mechanism 140 provided in this embodiment includes two cameras 141, which are used to photograph the product to be tested at both ends of the acupoint hole 124.

[0058] Specifically, the detection structure also includes a camera bracket 142, which is erected on the base plate 110 and its height is adjustable. The camera bracket 142 is provided with two dovetail groove guide rails 143, which are spaced apart vertically, and the extension direction of both dovetail groove guide rails 143 is perpendicular to the acupoint turntable 123. Two cameras 141 are slidably mounted on the two dovetail groove guide rails 143 respectively.

[0059] Each camera 141 consists of a camera body 1411, a coaxial light source 1412, and a backlight 1413. The camera body 1411, coaxial light source 1412, and backlight 1413 are arranged sequentially on corresponding dovetail groove guide rails 143 and slide in cooperation with the dovetail groove guide rails 143 respectively. In practical applications, the movement path of the multiple acupoint holes 124 on the acupoint turntable 123 passes between the coaxial light source 1412 and the backlight 1413 of the two cameras 141. The camera body 1411 of one camera 141 takes a picture of the product to be inspected from one end of the acupoint hole 124 entering the inspection station, obtaining image information of one end of the product to be inspected. The camera body 1411 of the other camera 141 takes a picture of the product to be inspected from the other end of the acupoint hole 124, obtaining image information of the other end of the product to be inspected.

[0060] The controller is communicatively connected to two camera bodies 1411 and the unloading mechanism 150. Based on the image information captured by the two camera bodies, the controller determines the defect type of the product to be inspected and obtains the detection results for end face dimensional deviation, end face appearance defects, foreign objects in the end face inner hole, or qualified products. When the product to be inspected arrives at the unloading station, the controller controls the unloading mechanism 150 to classify and unload the product according to the detection results.

[0061] In order to track the specific location of the product to be inspected in real time, the end face defect detection device 100 provided in this embodiment also includes a product tracking device 160. In the circumferential direction of the acupoint turntable 123, the product tracking device 160 is located between the loading station and the inspection station and is configured to be triggered when the product to be inspected passes by, and to send out a positioning signal.

[0062] The controller is communicatively connected to the product tracking device 160. Parameters such as the spacing between adjacent acupoints 124, the specific number of acupoints 124, and the specific locations of the detection station and the unloading station are all preset internally. Whenever the product tracking device 160 is triggered, the controller can accurately bind the detection result of the product to be inspected to its specific location based on these preset parameters, and ensure the accuracy of the unloading mechanism 150 in classifying and unloading materials.

[0063] Please refer to the following: Figure 8 , Figure 8 As shown Figure 1 A magnified view of region B in the middle.

[0064] The feeding mechanism 150 provided in this embodiment includes an air blowing device 151, a plurality of guide tubes 152 and a plurality of receiving boxes 153. The air blowing device 151 is provided with a plurality of air blowing needles 1511, and the plurality of air blowing needles 1511 are arranged one-to-one with one end of a plurality of acupoint holes 124. One end of the plurality of guide tubes 152 is arranged one-to-one with one end of the plurality of acupoint holes 124 away from the air blowing needles 1511, and the other end of the plurality of guide tubes 152 extends to the plurality of receiving boxes 153 respectively.

[0065] In this embodiment, there are four air-blowing needles 1511, four guide tubes 152, and four receiving boxes 153. These are combined in a one-to-one correspondence to form four unloading modules. Each of the four unloading modules corresponds one-to-one with one of the four acupoints 124 at the unloading station, enabling the classification and unloading of products based on four types of inspection results: end-face dimensional deviation, end-face appearance defects, foreign matter in the end-face inner hole, and qualified products. In other words, the four receiving boxes 153 respectively store products with end-face dimensional deviation, products with end-face appearance defects, products with foreign matter in the end-face inner hole, and products with qualified products.

[0066] In practice, the air blowing device 151 is equipped with four control valves 154 corresponding to the four air blowing needles 1511, and all four control valves 154 are communicatively connected to the controller. In actual application, after the controller obtains the detection result of a product to be inspected, and the controller determines that the product has entered the unloading station based on the arrival signal sent by the product tracking device 160 and the preset parameters, and when the product is aligned with the air blowing needle 1511 and the guide tube 152 of the unloading module corresponding to the detection result, the controller controls the control valve 154 corresponding to the air blowing needle 1511 to open, so that the air blowing needle 1511 blows the product to be inspected into the corresponding guide tube 152, and falls into the corresponding receiving box 153 along the guide tube 152, completing the sorting and unloading.

[0067] In summary, the end-face defect detection device 100 provided in this embodiment has the characteristics of higher detection efficiency and more accurate detection results.

[0068] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
