Description

Technical Field

[0001] This invention relates to the technical field of automated processing equipment for automotive parts, specifically to an automated visual inspection device and method for automotive parts. Background Technology

[0002] In the production and processing of round automotive parts, forming and extrusion are critical processes. Traditional production relies heavily on manual feeding, manual alignment, and manual extrusion, resulting in low efficiency, high labor intensity, and poor workpiece placement consistency, leading to misalignment during die insertion and a high scrap rate. Existing simple automated equipment only has basic feeding functions and some simple intelligent sensors for identification. It cannot meet the inspection standards for new materials and new products. Furthermore, existing equipment lacks integrated designs such as front-view posture detection, automatic rejection of defective products, secondary inspection before die insertion, flexible limiting clamping, pressure stabilizing and buffering extrusion, and magnetic directional unloading. The process connections are loose, and the workpieces are easily bumped during transfer and clamping. The extrusion process lacks limiting and buffering structures, resulting in insufficient processing accuracy and operational stability. At the same time, good and defective products cannot be automatically classified and stored, resulting in a low overall level of automation and making it difficult to meet the needs of large-scale continuous high-precision production.

[0013] A visual inspection method for automotive parts includes the following steps: S1. Automatic and orderly feeding: The vibratory feeder outputs round automotive parts in an orderly manner. The parts are guided and conveyed by the guide table. The laser counting sensor detects the incoming material, realizing automatic and continuous feeding of the equipment. S2. Visual inspection of workpiece posture: The alignment inspection camera performs visual photographic inspection of the posture and placement of the conveyed workpiece to determine whether the workpiece posture meets the processing requirements. S3. Automatic rejection of defective workpieces: Visual inspection determines that the workpiece has an unqualified posture. The unloading cylinder drives the joint stop to move, and the workpiece slides down the U-shaped guide chute into the waste collection box, completing the automatic rejection of defective products. S4. Negative pressure transfer of qualified workpieces: Once the workpiece is in the correct posture, it is transported to the transfer platform for positioning. The sliding conveyor mechanism drives the vacuum pump and negative pressure adsorption head to adsorb the workpiece and move it to the clamping position. S5. Precise workpiece clamping and mold placement: The rodless cylinder 2 drives the finger gripping cylinder 1 and the gripping rubber head 1 to clamp and fix the workpiece, and the sliding conveyor mechanism 2 moves the workpiece and places it inside the receiving platform to complete the precise mold entry and positioning. S6. Workpiece re-inspection upon mold placement: The mold entry inspection camera performs a secondary visual inspection of the workpiece position after it enters the mold to confirm that the workpiece is not misaligned and to avoid extrusion deviation. S7. Hydraulic extrusion processing of workpieces: The hydraulic cylinder drives the transmission platform and the extrusion column to move downwards and perform extrusion and shaping operations on the workpiece on the docking platform. The stabilizing column, the pressure reducing head and the pressure reducing spring work together to ensure stable positioning during the extrusion process. S8. Extruding the workpiece by magnetic attraction and moving it to the left for discharge: After the extrusion operation is completed, the sliding conveyor mechanism moves the magnetic column to the left, and moves the finished workpiece that has been adsorbed and fixed to the discharge station on the left side of the receiving platform, aligning it with the inlet end of the open discharge pipe. S9. Pushing and knocking down material, and collecting material from the pipeline: The rodless cylinder five-drive pusher plate slides down rapidly along the outer surface of the magnetic column, knocking the finished workpiece that is magnetically attracted to the magnetic column down. The workpiece falls directly into the feed end of the open discharge pipe, and after being guided and conveyed by the discharge pipe, it finally slides down and is collected in the qualified material collection box, completing a single automated processing flow.

[0014] The beneficial effects of this invention are: 1. This invention sets up a front and rear dual vision detection mechanism. The loading station completes the initial identification of the workpiece posture through the alignment detection camera and automatically rejects the workpiece with a skewed posture. After entering the mold, the position is re-inspected through the mold entry detection camera. The dual detection eliminates the problems of misalignment and misstate extrusion from the source, effectively reduces the product scrap rate, and significantly improves the yield of parts processing.

[0015] 2. This invention adopts a dual-mode material handling structure that combines negative pressure adsorption with flexible cylinder clamping. Combined with vertical positioning of limiting pressure columns, it forms a double limiting clamping method, which can adapt to the shape characteristics of round workpieces and achieve flexible transfer clamping without bumps or scratches. It avoids the defects of traditional rigid clamping that easily damages the surface of the workpiece and ensures the appearance quality and transfer stability of the product.

[0016] 3. The present invention adds a stabilizing column limiter, a pressure reducing spring buffer and a pressure stabilizing support column auxiliary support structure to the extrusion station, which can effectively buffer the instantaneous extrusion force, limit the extrusion downward displacement, reduce equipment operation vibration, make the extrusion operation process stable and controllable, improve the forming and processing accuracy, and extend the service life of the equipment structure.

[0017] 4. The present invention realizes the automatic feeding, counting and conveying, visual inspection, defective rejection, adsorption and temporary storage, limit clamping, precise mold entry, pressure stabilization and extrusion, magnetic material transfer and pipeline unloading of the whole process. No manual intervention is required throughout the process, which greatly reduces the reliance on manual labor, reduces labor intensity, improves the overall processing efficiency of the production line, and is suitable for large-scale continuous industrial production scenarios.

[0018] 5. This invention adopts a magnetic material transfer design combined with an open discharge pipe for directional unloading. Finished workpieces are guided by the pipe to slide into the qualified material collection box, avoiding free fall, collision, deformation, and messy accumulation. At the same time, defective workpieces are automatically guided into the waste collection box, and good and defective products are automatically classified and stored. The equipment has a compact process connection, high integration, safe and reliable operation, and strong versatility and practicality. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1-19As shown, the present invention discloses an automated visual inspection device for automotive parts, comprising: a working environment ground 1; a visual inspection transmission assembly 2 for continuously conveying qualified parts is disposed at the front right of the upper surface of the working environment ground 1; a waste collection box 3 for collecting misaligned parts is disposed at the rear right of the upper surface of the visual inspection transmission assembly 2; a continuous extrusion assembly 4 for continuously extruding parts is fixedly installed at the rear left of the visual inspection transmission assembly 2 and on the upper surface of the working environment ground 1; a support frame 5 is fixedly installed on the left side of the continuous extrusion assembly 4 and on the upper surface of the working environment ground 1; a qualified material collection box 6 is placed on the upper surface of the support frame 5; and a control panel 7 is fixedly installed on the upper surface of the right end of the visual inspection transmission assembly 2.

[0023] The visual inspection transmission component 2 includes an equipment support box 201. The bottom of the equipment support box 201 is placed on the right front of the upper surface of the working environment ground 1. A buffer support platform 202 is fixedly installed at the middle of the upper front surface of the equipment support box 201 by multiple screws and nuts. A vibratory feeder 203 is fixedly installed on the upper front surface of the buffer support platform 202 by multiple bolts. A laser counting sensor 204 is fixedly installed on the upper surface of the discharge channel at the top of the vibratory feeder 203. A standing mounting plate 205 is fixedly connected to the rear of the equipment support box 201. A guide plate 206 with a self-limiting plate is fixedly connected to the upper end of the standing mounting plate 205.

An inclined U-shaped guide trough 209 is fixedly installed on the back of the upper end of the standing mounting plate 205.

[0024] An assembly bracket 210 is fixedly installed between the vibratory feeder 203 and the first standing mounting plate 205 and on the upper surface of the equipment support box 201. A alignment detection camera 211 is fixedly installed on the lower surface of the upper end of the assembly bracket 210 and is positioned directly above the joint stop block 208. A second standing mounting plate 212 is fixedly installed on the left side of the first standing mounting plate 205 and on the upper surface of the equipment support box 201. A transfer platform 213 is fixedly connected to the middle of the upper surface of the second standing mounting plate 212. A second laser counting sensor 214 is fixedly installed on the left side of the transfer platform 213 and on the upper surface of the second standing mounting plate 212.

[0025] The system includes a positioning detection camera 211, a discharge cylinder 207, a seam stop 208, and a U-shaped guide chute 209. The posture of the workpiece is detected by visual photography. Unqualified workpieces are released by the discharge cylinder 207 and automatically slide down and collect along the guide chute. This achieves automatic detection of workpiece posture and automatic rejection of defective products, reducing manual sorting and lowering the scrap rate from the source.

[0026] A standing mounting plate 215 is fixedly connected to the rear of the standing mounting plate 205 and to the upper surface of the equipment support box 201. A sliding conveyor mechanism 216 is fixedly installed on the front of the upper end of the standing mounting plate 215. A rodless cylinder 217 is fixedly installed on the right side of the sliding table of the sliding conveyor mechanism 216.

[0027] The system incorporates a sliding conveyor mechanism 216, a negative pressure adsorption head 220, a finger gripping cylinder 223, and a limiting pressure column 226. The sliding conveyor mechanism 216 synchronously drives the adsorption structure and the gripping structure to move in a time-sharing manner, first using negative pressure to temporarily store the material, and then using the limiting pressure column to press down for positioning in conjunction with flexible gripping and transfer. This enables alternating operation of two workstations, simplifies the overall machine drive layout, and improves the efficiency and positioning stability of workpiece conveying and transfer.

[0028] A rodless cylinder 221 is fixedly installed on the left side of the front of the sliding conveyor 216. A transmission frame 222 is fixedly connected to the front of the moving end of the rodless cylinder 221. A finger gripping cylinder 223 is fixedly installed on the bottom surface of the transmission frame 222.

[0029] The device is equipped with a finger gripping cylinder 223, a gripping rubber head 224, a limiting pressure column 226, a finger gripping cylinder 410, a gripping rubber head 411, and a limiting pressure column 413. When the device moves downwards, the limiting pressure column first vertically presses the workpiece to a limit, and then the gripping rubber head flexibly hugs and clamps the circular workpiece. This forms a linkage action of upper pressure limiting and flexible clamping, which avoids workpiece slippage and surface scratches, and is suitable for the need for damage-free transportation of circular parts.

[0030] The continuous extrusion assembly 4 includes an extrusion equipment body 401. The bottom of the extrusion equipment body 401 is fixedly installed at the center of the upper rear surface of the working environment ground 1.

A driven mounting plate 1 409 is fixedly installed on the front of the moving end of the rodless cylinder 3 408. A finger gripping cylinder 2 410 is fixedly installed on the lower surface of the driven mounting plate 1 409.

A limit pressure column 2 413 is fixedly installed in the hole at the left end of the driven mounting plate 2 412.

[0032] The system incorporates a sliding conveyor mechanism 406, a magnetic column 417, a rodless cylinder 418, a pusher plate 419, and an open discharge pipe 432. The magnetic column 417 magnetically attracts and laterally moves the finished workpiece, while the rodless cylinder 418 drives the pusher plate 419 downward to knock the workpiece down. The workpiece is then directed and discharged into the material box through the discharge pipe 432, thus achieving automatic material transfer, collision-free directional unloading, and automatic collection and storage of finished products.

[0033] A synchronous mounting plate 414 is fixedly installed on the left side of the upper surface of the sliding conveyor 406.

A magnetic column 417 is fixedly installed in the hole at the right end of the driven mounting plate 416.

A pusher plate 419 that is stuck on the surface of the magnetic column 417 is fixedly installed on the front of the moving end of the rodless cylinder 418.

[0034] The top of the extrusion equipment body 401 is fixedly mounted with a main mounting plate 420 by multiple bolts. Inside the extrusion equipment body 401, the guide columns are all fitted with transmission mounting platforms 421. A hydraulic cylinder 422 is fixedly mounted in the middle of the upper surface of the main mounting plate 420. An extrusion head 423 for extruding parts is fixedly mounted in the center of the bottom of the transmission mounting platform 421. A synchronous mounting plate 424 is fixedly mounted on the surface of the middle section of the extrusion head 423 by a sealing plate. A stabilizing column 425 is fixedly mounted in the holes at both the front and rear ends of the synchronous mounting plate 424. Two stabilizing columns 425 are respectively positioned directly below the stabilizing columns 425 on the upper surface of the front and rear ends of the receiving platform 403. The limiting insertion hole 426, the front right side of the upper surface of the receiving platform 403 is fixedly installed with a mold entry detection camera 427 by a mounting bracket, the lower surface of the front and rear ends of the transmission platform 421 is fixedly connected with two positioning sleeves 428 with detachable sealing plates, the inner cavity of the lower end of each positioning sleeve 428 is movably inserted with a pressure reducing head 429, and the side of each pressure reducing head 429 opposite to each positioning sleeve 428 is fixedly connected with a pressure reducing spring 430, the front and rear of the bottom surface of the inner cavity of the extrusion equipment body 401 are fixedly installed with a pressure stabilizing support column 431, and the center of the left end face of the receiving platform 403 is fixedly installed with an open discharge pipe 432.

[0035] The system incorporates a hydraulic cylinder 422, an extrusion head 423, a stabilizing column 425, a pressure-reducing spring 430, and a pressure-stabilizing support column 431. During extrusion, all components move synchronously downwards. The stabilizing column 425 precisely limits and prevents deviation, the pressure-reducing spring 430 buffers instantaneous extrusion force, and the pressure-stabilizing support column 431 provides bottom pressure support. This effectively reduces equipment vibration and workpiece deformation under pressure, improving extrusion shaping accuracy and equipment operational stability.

[0036] Among them, by setting up a positioning detection camera 211, a mold entry detection camera 427, and a receiving platform 403, the workpiece loading posture is initially inspected and the mold entry position is re-inspected. The extrusion process is started only after the workpiece is confirmed to be qualified by dual visual control, so as to prevent the processing defects caused by misalignment when entering the mold and ensure the consistency of product processing and yield rate.

[0037] This device uses the working environment ground 1 as the overall installation base. The control panel 7 controls all mechanisms to achieve continuous cyclical automated detection, screening, conveying, clamping, extrusion, material picking and unloading operations. The equipment adopts a dual-station synchronous linkage alternating operation mode. The negative pressure adsorption structure and the flexible clamping structure are synchronously mounted on the sliding conveyor mechanism 216 and move synchronously with it. Through the combination of dual structure alternating operation, dual vision inspection and verification, dual limit clamping, pressure stabilizing extrusion shaping and pipeline directional unloading, a fully automated integrated processing flow for automotive round parts is realized.

[0038] During operation, after the equipment is started, the vibratory feeder 203 continuously and orderly outputs round automotive parts. The parts are stably conveyed along the guide table 206. The laser counting sensor 204 counts the number of conveyed parts in real time. When the first part is accurately conveyed to the inner side of the joint stop 208 and forms a shape matching and alignment with the arc-shaped inner wall of the joint stop 208, the alignment detection camera 211 starts shooting and detection to accurately identify whether the current placement posture and position of the part meet the processing standards. If the workpiece is detected to be skewed or the placement position is offset, the unloading cylinder 207 is immediately started to drive the joint stop 208 to move laterally, releasing the limit block on the workpiece. The unqualified workpiece slides down by itself and is guided and conveyed along the U-shaped guide chute 209, and finally falls into the waste collection box 3 to complete the automatic rejection of defective products. If the workpiece is detected to be aligned and the position is qualified, the workpiece stays in the original position and waits for the subsequent material handling and transfer process. In its initial state, the sliding conveyor mechanism 216 is positioned to the left of the alignment detection camera 211 and is in standby mode. The negative pressure adsorption material handling component and the flexible clamping and transfer component, which are synchronously assembled on its upper part, can move left and right synchronously with the sliding conveyor mechanism 216. After the first workpiece passes inspection and is positioned, the sliding conveyor mechanism 216 drives the vacuum pump 219, the negative pressure adsorption head 220, the finger clamping cylinder 223, the clamping rubber head 224, and the limiting pressure column 226 to move synchronously to the right, so that the negative pressure adsorption head 220 is precisely aligned above the qualified workpiece. Then, the rodless cylinder 217 drives the negative pressure adsorption head 220 to move vertically downward and close to the workpiece surface. The vacuum pump 219 works to generate negative pressure suction, causing the negative pressure adsorption head to move downward. 220 stably adsorbs and fixes the circular workpiece. After adsorption, rodless cylinder 217 drives the workpiece to rise vertically and reset. Sliding conveyor 216 drives the entire assembly to move to the right again, transferring the adsorbed workpiece to the upper part of the transfer platform 213 for standby. During this process, the alignment detection camera 211 can simultaneously perform a new round of posture detection on the workpieces that are subsequently transported to the position, realizing the parallel operation of the transfer and detection processes. After the workpiece is aligned, rodless cylinder 217 drives the negative pressure adsorption head 220 to move down again. Vacuum pump 219 releases the negative pressure state, and the workpiece is stably placed on the upper surface of the transfer platform 213 by its own weight to complete temporary storage. Laser counting sensor 214 simultaneously counts the number of qualified workpieces. The equipment continuously cycles through feeding and posture detection. When the next workpiece passes inspection and is ready for further processing, the sliding conveyor mechanism 216 moves the entire assembly to the left, causing the finger gripping cylinder 223 and its associated structure to move above the inspection station for a secondary posture check. Simultaneously, it precisely aligns with the qualified workpiece temporarily stored on the transfer platform 213. The rodless cylinder 221 then activates, causing the finger gripping cylinder 223, the gripping head 224, and the limiting pressure column 226 to move vertically downwards as a whole. The limiting pressure column 226 preferentially contacts the upper surface of the workpiece to achieve vertical limiting and anti-deviation. Subsequently, the finger gripping cylinder 223 drives the gripping head... The first 224 retracts and firmly clamps the circular workpiece through a flexible bonding method, forming a dual positioning structure of upper pressure limit and circumferential clamping, which greatly improves the clamping stability. After clamping is completed, the structure is vertically reset. At the same time, the negative pressure adsorption component completes a new round of workpiece picking. The sliding conveyor mechanism 216 moves to the right again and places the newly adsorbed workpiece on the transfer platform 213 for temporary storage. At the same time, the firmly clamped workpiece is transferred to the upper end face of the receiving column 405 for positioning and parking. Then, the second sliding conveyor mechanism 404 drives the receiving column 405 and the workpiece to move backward and transport the workpiece to the clamping station inside the extrusion equipment body 401. After the workpiece is conveyed to the designated position, the sliding conveyor mechanism 3 406 drives the finger gripping cylinder 2 410, the gripping head 2 411, and the limiting pressure column 2 413 to move synchronously above the workpiece. The rodless cylinder 3 408 drives the entire clamping structure to move downward, and the limiting pressure column 2 413 vertically limits and presses the workpiece. Then, the gripping head 2 411 flexibly clamps the workpiece to complete a second precise clamping, effectively preventing loosening and deviation during transfer. Subsequently, the sliding conveyor mechanism 2 404 resets, and the sliding conveyor mechanism 3 406 moves the workpiece horizontally to the top of the mold cavity of the receiving platform 403 and lowers the workpiece, allowing it to fall precisely into the workpiece slot of the receiving platform 403. After the workpiece is placed into the mold, the mold inspection camera 427 starts a second visual inspection to confirm that the workpiece position and posture are without deviation. Then, the hydraulic cylinder 422 pushes the transmission platform 421 and the extrusion column head 423 to press vertically downwards to perform extrusion and shaping operations on the workpiece inside the docking table 403. During the extrusion process, the stabilizing column 425 is inserted into the limiting hole 426 to achieve vertical anti-deviation limit. At the same time, the positioning sleeve 428, the pressure reducing head 429, and the pressure reducing spring 430 work together to buffer the instantaneous extrusion force. The pressure stabilizing support column 431 provides bottom support to ensure a smooth and accurate extrusion process. After the extrusion is completed, the hydraulic cylinder 422 drives the extrusion structure to move upwards and reset. After the extrusion process is completed, the sliding conveyor mechanism 3 406 drives the magnetic column 417, the rodless cylinder 5 418 and the pusher plate 419 to move synchronously, so that the magnetic column 417 is close to the extruded finished workpiece and the workpiece is stably attracted by magnetic force. Then, the sliding conveyor mechanism 3 406 drives the magnetic column 417 and the workpiece to move to the left as a whole, and accurately transfers the workpiece to the upper part of the feed end of the open discharge pipe 432 on the left side of the receiving table 403 for alignment. After alignment, the rodless cylinder 5 418 drives the pusher plate 419 to slide down quickly along the outer surface of the magnetic column 417 to impact and force the magnetically attracted finished workpiece to fall off. The workpiece falls accurately into the feed end of the discharge pipe 432, and after being directionally guided and conveyed by the internal channel of the discharge pipe 432, it slides smoothly into the qualified material collection box 6, completing the fully automated processing of a single workpiece. The equipment continuously cycles through all the above processes to realize the continuous automated production of large batches of automotive parts.

[0039] A visual inspection method for automotive parts includes the following steps: S1. Automatic and orderly feeding: Vibratory feeder 203 outputs round automotive parts in an orderly manner. The parts are guided and conveyed by guide table 206. Laser counting sensor 204 senses the incoming material and realizes automatic continuous feeding of the equipment. S2. Visual inspection of workpiece posture: The alignment inspection camera 211 performs visual photographic inspection of the posture and placement of the conveyed workpiece to determine whether the workpiece posture meets the processing requirements. S3. Automatic rejection of defective workpieces: Visual inspection determines that the workpiece has an unqualified posture. The unloading cylinder 207 drives the joint stop 208 to move, and the workpiece slides down the U-shaped guide chute 209 into the waste collection box 3, completing the automatic rejection of defective products. S4. Negative pressure transfer of qualified workpieces: The workpiece with the correct posture is transported to the transfer platform 213 for positioning. The sliding conveyor mechanism 216 drives the vacuum pump 219 and the negative pressure adsorption head 220 to adsorb the workpiece and transfer it to the clamping position. S5. Precise workpiece clamping and mold placement: The rodless cylinder 221 drives the finger gripping cylinder 223 and the gripping rubber head 224 to clamp and fix the workpiece. The sliding conveyor mechanism 404 transfers the workpiece and places it inside the receiving table 403 to complete the precise mold entry positioning. S6. Workpiece re-inspection upon mold placement: The mold entry inspection camera 427 performs secondary visual inspection on the position and status of the workpiece after it enters the mold to confirm that the workpiece is not misaligned and to avoid extrusion deviation. S7. Hydraulic extrusion processing of workpieces: Hydraulic cylinder 422 drives transmission platform 421 and extrusion head 423 to move downwards, and performs extrusion and shaping operations on workpieces on material table 403. Stabilizing column 425, pressure reducing head 429 and pressure reducing spring 430 work together to ensure stable positioning during the extrusion process. S8. Extruding the workpiece by magnetic attraction and moving it to the left for discharge: After the extrusion operation is completed, the sliding conveyor 406 drives the magnetic column 417 to move to the left, and moves the finished workpiece that has been adsorbed and fixed to the discharge station on the left side of the receiving platform 403, aligning it with the inlet end of the open discharge pipe 432. S9. Pushing and knocking down material, and collecting material from the pipeline: The rodless cylinder 418 drives the pusher plate 419 to slide downward along the outer surface of the magnetic column 417, knocking the finished workpiece that is magnetically attracted to the magnetic column 417 downward. The workpiece falls directly into the feed end of the open discharge pipe 432. After being guided and conveyed by the discharge pipe 432, it finally slides down and is collected in the qualified material collection box 6, completing a single automated processing flow.
