Description

Technical Field

[0001] This utility model belongs to the field of shaft inspection technology, specifically relating to a batch visual inspection device for shaft parts. Background Technology

[0002] In modern industrial production, shafts, as key components in mechanical transmission systems, are widely used in various fields such as automobiles, aerospace, and machinery manufacturing. The quality of shafts directly affects the performance, reliability, and service life of the entire mechanical system; therefore, accurate testing of parameters such as dimensional accuracy and surface quality of shafts is crucial.

[0003] Announcement No. CN 212525013U discloses an automatic inspection device for shaft parts based on machine vision. This utility model achieves automatic feeding of shaft parts to be inspected through grooved rollers, automatic surface quality inspection of parts through an automatic inspection module based on a vision system, and automatic sorting of defective and good products through an automatic sorting mechanism, realizing unmanned quality inspection. However, during the inspection process, the shaft parts can be completely stuck in the clamping groove, causing part of the shaft part to be in close contact with the clamping groove wall, and the shaft parts are difficult to rotate smoothly. Even if they can rotate, the rotation effect is not ideal, and multiple rotations are not possible. This makes it impossible for many parts of the part to be fully inspected by the vision system, seriously affecting the comprehensiveness and accuracy of the inspection. In addition, in the automatic sorting mechanism, the sorted shaft parts fall out of the clamping groove and roll down the top surface of the sorting guide plate into the good product cavity or the defective product cavity. This free fall can cause collision damage to the shaft parts, and the cavity is cluttered. Meanwhile, the haphazard stacking of shaft parts inside the cavity makes subsequent sorting and statistics difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a batch visual inspection device for shaft parts. This device achieves all-round inspection of shaft parts by clamping and rotating, and can classify and place them into scrap racks or qualified racks according to the inspection structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a batch visual inspection equipment for shaft parts, including a cabinet, on which a feeding component, a clamping and moving component and an inspection component are provided, a clamping and rotating component is provided below the inspection component, and a scrap rack and a qualified rack are provided on one side of the inspection component;

[0006] The feeding assembly includes a feeding bin, a feeding chute installed below the feeding bin, a guide roller rotatably installed inside the feeding chute, a slot on the guide roller, and a conveyor belt installed below the feeding chute.

[0007] The clamping and moving assembly includes a track, a translation plate slidably mounted on the track, a first cylinder vertically mounted on the translation plate, a connecting plate mounted on the output end of the first cylinder, a second cylinder mounted on the connecting plate, a dual-axis cylinder mounted on the output end of the second cylinder, and chucks mounted on the two output shafts of the dual-axis cylinder, the chucks being capable of linear movement in the lateral, longitudinal and vertical directions.

[0008] The detection component includes a detection head, which can be adjusted at multiple angles within a space;

[0009] The clamping and rotating assembly has two shaft seats, each with a rotating shaft rotatably mounted on it. Clamping plates are mounted on the opposite surfaces of the two rotating shafts. One rotating shaft is connected to an electric cylinder, and the other rotating shaft is connected to a third motor.

[0010] Furthermore, the feeding hopper is funnel-shaped with a rectangular opening at the top. Shaft-type parts are placed inside the feeding hopper. The feeding hopper includes two parallel side plates, with an inclined plate installed between the two side plates. The bottoms of the two inclined plates are close to each other, forming a V-shaped structure. The discharge chute is installed below the two inclined plates.

[0011] Furthermore, rectangular through holes are respectively opened at corresponding positions on the upper and lower parts of the feeding trough, and the upper and lower rectangular through holes are aligned in the vertical direction.

[0012] Furthermore, the two ends of the guide roller extend from the side plates, one end of the guide roller is connected to the first motor, and the slots are distributed in an array along the circumference of the guide roller. Shaft-type parts can be inserted into the slots, and only a single shaft-type part can be inserted.

[0013] Furthermore, the conveyor belt includes two rollers, a transmission belt is installed between the two rollers, the transmission belt is provided with grooves, a main sprocket is installed at one end of the rollers, a driven sprocket is installed at one end of the guide roller, a chain is installed between the main sprocket and the driven sprocket, and a receiving plate is installed at the end of the conveyor belt. The upper surface of the receiving plate is inclined, and its end is an arc-shaped groove.

[0014] Furthermore, the clamping and moving assembly includes a support base, a fixed plate horizontally mounted on the top of the support base, a track horizontally mounted along the length of the fixed plate, a first cylinder vertically mounted on the translation plate, clamping seats at the top of the two output shafts of the dual-axis cylinder, a chuck mounted on the lower end of the clamping seat, and a bayonet provided on the inner side of the chuck.

[0015] Furthermore, a screw is rotatably mounted in the middle of the track, and a matching slider is mounted on the screw. The slider is fixedly connected to the translation plate, and a second motor is connected to one end of the screw.

[0016] Furthermore, the detection component includes a bracket with a mounting plate on it. A vertical shaft is rotatably mounted on the mounting plate, and a rotating block is mounted below the vertical shaft. A horizontal shaft is rotatably mounted on the rotating block, and a mounting block is rotatably mounted at one end of the horizontal shaft. The detection head is fixedly mounted on the mounting block, and a computer module is mounted on one side of the cabinet. The computer module is connected to the detection head via a wire.

[0017] Furthermore, the clamping and rotating assembly includes a base, which is horizontally fixed on the cabinet, and two bearings are linearly installed along the length of the base with a certain distance between them. Two rotating shafts are installed opposite each other on the two bearings.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: Several shaft parts to be tested are placed in the feeding hopper and slide down the inclined plate into the feeding trough by their own gravity. At this time, the first motor drives the guide roller to rotate, and the shaft parts fall into the slots of the guide roller. As the guide roller rotates, the shaft parts are conveyed to the feeding port and fall into the groove on the transmission belt below. When the guide roller rotates, the conveyor belt can be driven by the chain drive structure. The shaft parts can move with the conveyor belt to its end and then slide onto the receiving plate. At this time, the shaft parts can be clamped and moved to the detection assembly for detection by the clamping and moving assembly. During the detection process, the electric cylinder can drive one rotating shaft to approach another rotating shaft and clamp the shaft parts between the two clamping plates. Then, the third motor drives the rotating shaft to rotate, thereby driving the shaft parts to rotate. The shaft parts are detected from all directions. After the detection is completed, the clamping and moving assembly can classify and place the shaft parts into different placement racks according to the detection results.

[0019] This invention utilizes a clamping and moving assembly to hold shaft-like parts between two clamping plates. A third motor drives a rotating shaft to rotate the shaft-like parts, avoiding the problem of parts getting stuck in the clamping slots and hindering rotation in existing technologies. This ensures that the vision system can fully inspect all parts of the shaft-like parts. After inspection, the clamping and moving assembly removes the shaft-like parts based on the inspection results and classifies them into scrap racks or qualified racks. This replaces the method of parts freely rolling down in existing technologies, avoiding secondary damage caused by falling collisions. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1-2 As shown, this utility model provides a batch visual inspection device for shaft parts, including a cabinet 100. The cabinet 100 is a rectangular frame structure. A feeding assembly is provided at one end of the cabinet 100, a detection assembly is provided on one side of the feeding assembly, and a clamping and moving assembly is provided on one side of the detection assembly. The feeding assembly can provide shaft parts to be inspected. The clamping and moving assembly can clamp and move the shaft parts on the feeding assembly into the detection assembly. The detection assembly inspects the shaft parts, and based on the inspection results, the clamping and moving assembly then classifies and collects the shaft parts.

[0030] See Figure 3-4 As shown, the aforementioned feeding assembly includes a feeding bin, which is funnel-shaped with a rectangular opening at the top. Shaft-type parts are placed inside the feeding bin. The feeding bin includes two parallel side plates 101 fixedly mounted on the cabinet 100. An inclined plate 102 is installed between the two side plates 101, with the bottoms of the two inclined plates 102 close to each other, forming a V-shaped structure. A cylindrical discharge trough 103 is installed below the two inclined plates 102. Rectangular through holes are respectively opened at corresponding positions at the top and bottom of the discharge trough 103. The two rectangular through holes are aligned vertically to form a through rectangular discharge channel. A cylindrical guide roller 105 is rotatably mounted inside the discharge trough 103. Both ends of the guide roller 105 extend from the side plates 101, and one end of the guide roller 105 is connected to a first motor 106.

[0031] The guide roller 105 is provided with several slots 107, the width of which is smaller than the width of the discharge port 104. Shaft-type parts can be inserted into the slots 107, and each slot 107 can only accommodate a single shaft-type part. A conveyor belt is provided below the discharge chute 103. The conveyor belt includes two rollers 108, and a drive belt 109 is installed between the two rollers 108. The drive belt 109 is provided with grooves to hold shaft-type parts in place and prevent them from rolling on the surface of the drive belt 109. A receiving plate 110 is fixedly installed at the end of the conveyor belt. The upper surface of the receiving plate 110 is inclined, and its end is an arc-shaped groove. When shaft-type parts slide down from the end of the conveyor belt to the receiving plate 110, they can slide down the inclined surface of the receiving plate 110 into the arc-shaped groove.

[0032] A main sprocket 111 is installed at one end of the guide roller 105, and a driven sprocket 112 is installed at one end of the roller 108. A chain 113 is installed between the main sprocket 111 and the driven sprocket 112. When the first motor 106 drives the guide roller 105 to rotate, the conveyor belt can be driven to run through the chain 113.

[0033] In addition, two baffles 114 are symmetrically arranged inside the feeding hopper. Each baffle 114 is fixedly connected to a stop post on its outer side. The stop post passes through the side plate 101 and extends outward. The stop post can be moved. By manipulating the extended stop post, the distance between the two baffles 114 can be adjusted to accommodate shaft parts of different lengths.

[0034] Several shaft parts to be inspected are placed in the feeding hopper and slide down the inclined plate 102 into the discharge chute 103 under their own weight. At this time, the first motor 106 drives the guide roller 105 to rotate, and the shaft parts fall into the slot 107 of the guide roller 105. As the guide roller 105 rotates, the shaft parts are conveyed to the discharge port 104 and slide down into the groove on the transmission belt 109 below. When the guide roller 105 rotates, it drives the conveyor belt through the chain drive structure. The shaft parts can move with the conveyor belt to its end and then slide onto the receiving plate 110. At this time, the shaft parts can be clamped and moved to the inspection assembly for inspection by the clamping and moving assembly. It should be noted that the receiving plate 110 receives one shaft part at a time.

[0035] See Figure 5 As shown, the clamping and moving assembly includes a support base 201. A fixing plate 202 is horizontally fixedly mounted on the top of the support base 201. A track 203 is horizontally mounted along the length of the fixing plate 202. A translation plate 204 is slidably mounted on the track 203. A first cylinder 205 is vertically fixedly mounted on the translation plate 204. A connecting plate 206 is fixedly mounted on the output end of the first cylinder 205. A second cylinder 207 is fixedly mounted on the connecting plate 206. The output end of the second cylinder 207 points vertically downward. A dual-axis cylinder 208 is mounted on the output end of the second cylinder 207. Clamping seats 209 are connected to the top ends of the two output shafts of the dual-axis cylinder 208. A chuck 210 is horizontally mounted on the lower end of each clamping seat 209. A bayonet is provided on the inner side of the chuck 210, which can be used to clamp shaft-like parts.

[0036] The aforementioned translation plate 204 can move horizontally on the track 203. Specifically, a screw 211 is rotatably mounted in the middle of the track 203, and a matching slider 212 is mounted on the screw 211. The slider 212 is fixedly connected to the translation plate 204. One end of the screw 211 is connected to a second motor 213, which, when rotated, can drive the translation plate 204 to move horizontally on the track 203.

[0037] The chuck 210 can move linearly in the lateral, longitudinal and vertical directions.

[0038] See Figure 6 As shown, the inspection assembly includes a bracket 301. An L-shaped mounting plate 302 is horizontally fixed to the top of the bracket 301. A vertical shaft 303 is rotatably mounted on the mounting plate 302. A rotating block 304 is mounted below the vertical shaft 303. A horizontal shaft 305 is horizontally rotatably mounted on the rotating block 304. A mounting block 306 is rotatably mounted to one end of the horizontal shaft 305. Positioning pins are provided on both the rotating block 304 and the mounting block 306, which can lock the vertical shaft 303 and the horizontal shaft 305 onto the rotating block 304 and the mounting block respectively. An inspection head 307 is fixedly mounted on the mounting block 306. Through the vertical shaft 303, the horizontal shaft 305, the rotating block 304, and the mounting block 306, the inspection head 307 can be adjusted at multiple angles within space. The inspection head 307 can use visual inspection technology to inspect various parameters of shaft parts and determine whether the parts are qualified. A computer module 308 is installed on one side of the cabinet 100. The computer module 308 is connected to the detection head 307 via a wire. The computer module 308 can display the detection results and is used to control the entire detection process.

[0039] A clamping and rotating assembly is provided below the detection head 307. The clamping and rotating assembly includes a base 401, which is horizontally fixedly mounted on the cabinet 100. Two bearing seats 402 are linearly mounted along the length of the base 401, with a certain distance between them. A rotating shaft 403 is horizontally rotatably mounted on each bearing seat 402. The two rotating shafts 403 are mounted opposite each other, and a disc-shaped clamping plate 404 is mounted on the opposite surface of the two rotating shafts 403.

[0040] An electric cylinder 405 is installed at one end of the base 401. The output end of the electric cylinder 405 is connected to one of the rotating shafts 403, and a third motor 406 is connected to the end of the other rotating shaft 403. Before testing, the shaft-like part is moved between the two clamping plates 404 by the chuck 210. Then, the electric cylinder 405 can drive one of the rotating shafts 403 to move closer to the other rotating shaft 403, clamping the shaft-like part between the two clamping plates 404. Finally, the third motor 406 drives the rotating shaft 403 to rotate, thereby rotating the shaft-like part, making the testing more comprehensive and accurate.

[0041] See Figure 1-2 As shown, a placement rack is provided on one side of the testing assembly. The placement rack is located within the horizontal stroke range of the track 203 and within the stroke range of the first cylinder 205. The placement rack is divided into a scrap rack 407 and a qualified rack 408. Both the scrap rack 407 and the qualified rack 408 are provided with several U-shaped grooves for placing the shaft parts that have completed testing. The clamping and moving assembly can classify and place the shaft parts into the scrap rack 407 or the qualified rack 408 according to the testing results.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
