Description

Technical Field

[0001] The present invention relates to the technical field of appearance detection, and particularly to an appearance inspection device for an automobile cylinder head. Background Art

[0002] In the process of automobile engine production, as an important component of the engine, the appearance quality of the cylinder head is directly related to the sealing performance, heat dissipation performance and overall operation stability of the engine. Once there are appearance defects on the cylinder head, such as cracks, scratches, air holes, etc., it may cause problems such as air leakage and oil leakage during the operation of the engine, thereby affecting the performance and service life of the engine, and even leading to safety accidents.

[0003] Traditional methods for inspecting the appearance of cylinder heads mainly rely on manual visual inspection. This method not only has low efficiency and is difficult to meet the requirements of large-scale production, but also the inspection results are extremely susceptible to the subjective factors, fatigue degree and experience level of the inspectors, resulting in frequent occurrences of missed inspections and misinspections. With the continuous expansion of the automobile production scale and the increasing requirements for product quality, the method of manual visual inspection can no longer meet the needs of the modern automobile manufacturing industry.

[0004] In recent years, automated inspection equipment using machine vision has emerged. However, in actual applications, some equipment can only perform simple appearance inspections and cannot accurately mark the defects of the cylinder head, which is not conducive to subsequent quality traceability and processing; some equipment lacks an effective classification and recycling mechanism for the inspected cylinder heads, and qualified products and unqualified products are often stored together, increasing the difficulty of subsequent management. Summary of the Invention

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments described herein. Instead, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to those skilled in the art.

[0028] Embodiment 1: As Figures 1-9As shown in the figure, an appearance inspection device for an automobile cylinder head includes a frame 1. There is a detection chamber 101 at the upper part of the frame 1. The left and right ends of the detection chamber 101 communicate with the outside. There is a recovery chamber 102 at the lower part of the frame 1. The front end of the recovery chamber 102 communicates with the outside. A through hole 103 communicating with the recovery chamber 102 is opened at the bottom inside the detection chamber 101. A loading plate 2 is slidably connected inside the detection chamber 101. Electric slide rails 1 3 are arranged on both the front and rear sides inside the detection chamber 101. The front and rear sides of the loading plate 2 are fixedly connected to the output ends of the two electric slide rails 1 3 respectively. Feeding grooves 202 and discharging grooves 203 are respectively arranged on the left and right sides of the loading plate 2. A through hole 201 matching the size of the through hole 103 is opened in the middle of the loading plate 2. A clamping mechanism 4 and a detection mechanism 5 are arranged above the through hole 103 inside the detection chamber 101. The clamping mechanism 4 is used to cooperate with the loading plate 2 to realize the loading and unloading operations of the cylinder head. The detection mechanism 5 includes an electric slide rail 2 501. The electric slide rail 2 501 is installed at the upper part inside the detection chamber 101. The output end of the electric slide rail 2 501 is connected to a multi-axis robotic arm 502. A high-definition camera 503 and a marking pen 504 are arranged at the end of the multi-axis robotic arm 502. The high-definition camera 503 is signal-connected to an external controller. Driven by the electric slide rail 2 501, the multi-axis robotic arm 502 moves back and forth inside the detection chamber 101. At the same time, the position of the high-definition camera 503 is further adjusted through the multi-axis robotic arm 502 to perform appearance inspections at multiple points on the cylinder head. When a defect is found, the marking pen 504 is operated through the multi-axis robotic arm 502 to mark the defective position of the cylinder head. A transfer mechanism 6 is arranged in the middle of the recovery chamber 102. Storage units 7 are arranged on both the left and right sides of the recovery chamber 102 and located on both sides of the transfer mechanism 6. The transfer mechanism 6 is used to receive the cylinder head lowered from the through hole 103 and transfer it to the storage unit 7.

[0029] As Figure 3 , Figures 7-9 shown in the figure, the clamping mechanism 4 includes a bidirectional lead screw module 401. The bidirectional lead screw module 401 is horizontally installed at the upper part inside the detection chamber 101. Both output ends of the bidirectional lead screw module 401 are connected to two cylinders 402. The telescopic rod ends of the two cylinders 402 on the same side are jointly connected to a flipping assembly. Clamping plates 407 are arranged on the sides of the two flipping assemblies close to each other. Driven by the bidirectional lead screw module 401, the two flipping assemblies approach or move away from each other, so as to realize the clamping or loosening action of the clamping plates 407 on the cylinder head. Furthermore, when the clamping plates 407 clamp the cylinder head, the flipping assembly can perform flipping operations on the cylinder head.

[0030] The flipping assembly includes a fixing frame 403 which is connected to the output end of a cylinder 402. A worm gear 404, a worm 405 and a motor 406 are installed in the fixing frame 403. The worm gear 404 meshes with the worm 405, and the worm 405 is in transmission connection with the motor 406. A clamping plate 407 is arranged outside the fixing frame 403 and is coaxially and fixedly connected to the worm gear 404. By driving the worm 405 to rotate through the motor 406, the worm gear 404 and the clamping plate 407 are driven to flip, so as to realize the flipping operation of the cylinder head.

[0031] As Figure 2 , Figure 3 and Figure 6 shown, the storage unit 7 includes storage cabinets 701. The two storage cabinets 701 are respectively arranged on the left and right sides of the transfer mechanism 6 in the recycling bin 102. A plurality of storage bins 702 are vertically and spaced apart on the side of the two storage cabinets 701 close to each other. Positioning tracks 703 are arranged on the left and right sides of the bottom in the recycling bin 102. The bottoms of the two storage cabinets 701 are respectively slidably connected to the two positioning tracks 703.

[0032] The transfer mechanism 6 includes two vertically arranged and front-back opposite electric slide rails three 601. A two-way forklift 602 is fixedly connected between the output ends of the two electric slide rails three 601. The two-way forklift 602 adopts the prior art and includes a lifting plate 603 that can extend left or right. There are two cushion strips two 604 parallel to the moving direction of the lifting plate 603 at the bottom in each storage bin 702. The cushion strips two 604 are used to support the cylinder head. The distance between the two cushion strips two 604 in the storage bin 702 is set to allow the lifting plate 603 to pass through without losing the support for the cylinder head.

[0033] As Figure 4 shown, lighting lamps 11 are symmetrically installed on the left and right at the top in the inspection bin 101. The lighting lamps 11 are used to provide lighting when the inspection mechanism 5 inspects the appearance of the cylinder head, so as to ensure that the high-definition camera 503 can clearly capture the appearance details of the cylinder head.

[0034] Working process of Embodiment 1: Initially, the material loading plate 2 is located in the middle of the detection bin 101. During use, the material loading plate 2 is driven to move leftward by the first electric slide rail 3, so that the feeding groove 202 of the material loading plate 2 extends out of the left side of the frame 1. Then, the cylinder head to be subjected to appearance inspection is placed in the feeding groove 202 of the material loading plate 2. Subsequently, the material loading plate 2 is driven to move rightward by the first electric slide rail 3 until the cylinder head in the feeding groove 202 is directly below the clamping mechanism 4. At this time, the discharging groove 203 of the material loading plate 2 will extend out of the right side of the frame 1. Then, the telescopic rod ends of the cylinders 402 corresponding to the two flipping assemblies extend until the clamping plates 407 on the two flipping assemblies descend to align with the middle parts of the front and rear sides of the cylinder head to be inspected respectively. Next, the two flipping assemblies are driven to approach each other by the bidirectional lead screw module 401 until the two clamping plates 407 respectively clamp the front and rear sides of the cylinder head to be inspected. Then, the telescopic rod ends of the cylinders 402 corresponding to the two flipping assemblies retract and reset, so that the cylinder head clamped by the two clamping plates 407 rises and moves out of the feeding groove 202 of the material loading plate 2. At this time, the multi-axis robotic arm 502 is driven to move by the second electric slide rail 501, and the moving path of the high-definition camera 503 is adjusted by the multi-axis robotic arm 502 to photograph the appearance of the cylinder head through the high-definition camera 503, and the information obtained by the photographing is transmitted to the external controller for analysis. The external controller analyzes the appearance information of the cylinder head. The lighting lamp 11 can provide sufficient lighting when the detection mechanism 5 inspects the appearance of the cylinder head, ensuring that the high-definition camera 503 can clearly capture the appearance details of the cylinder head, improving the accuracy of the detection. When there are appearance defects on the cylinder head, the moving path of the marking pen 504 is adjusted by the multi-axis robotic arm 502 to mark the cylinder head with appearance defects. When one side of the cylinder head is inspected, the corresponding worm 405 is driven to rotate by the two motors 406. Under the meshing transmission of the worm 405 and the worm gear 404, the two clamping plates 407 and the cylinder head clamped by them are flipped, so as to adjust the inspection surface of the cylinder head. When the four surfaces of the cylinder head are all inspected, the inspection result is determined by the external controller.

[0035] When the visual inspection result of the current cylinder head is qualified, the loading plate 2 is driven to move leftward by the electric slide rail 1 until the blanking groove 203 of the loading plate 2 is directly below the cylinder head. At this time, the feeding groove 202 of the loading plate 2 will extend outside the left side of the frame 1. Then, the telescopic ends of the cylinders 402 corresponding to the two flipping assemblies extend, causing the two clamping plates 407 and the cylinder head they hold to descend until the bottom surface of the cylinder head is supported by the inner bottom surface of the blanking groove 203 of the loading plate 2. Subsequently, the two flipping assemblies are driven to move away from each other by the bidirectional lead screw module 401 until the two clamping plates 407 release the clamping of the cylinder head. Then, the telescopic ends of the cylinders 402 corresponding to the two flipping assemblies retract and reset, causing the two clamping plates 407 to move out of the blanking groove 203 of the loading plate 2. At the same time, the next cylinder head to be inspected is placed in the feeding groove 202 of the loading plate 2. Then, the loading plate 2 is driven to move rightward by the electric slide rail 1 until the new cylinder head to be inspected in the feeding groove 202 is directly below the clamping mechanism 4. At this time, the cylinder head with qualified inspection results extends outside the right side of the frame 1 along with the blanking groove 203 of the loading plate 2, facilitating the removal of the cylinder head with qualified inspection results. Subsequently, the above inspection operation of the cylinder head can be repeated to perform a visual inspection on the new cylinder head to be inspected in the feeding groove 202.

[0036] When the visual inspection result of the current cylinder head is unqualified, the loading plate 2 is driven to move leftward by the electric slide rail 13 until the second through hole 201 of the loading plate 2 is vertically aligned with the first through hole 103 of the frame 1. At this time, the telescopic ends of the cylinders 402 corresponding to the two flipping assemblies extend, causing the two clamping plates 407 and the cylinder head clamped by them to descend, and the electric slide rail 3601 drives the double-directional forklift 602 to move upward until the bottom surface of the cylinder head is received by the lifting plate 603 of the double-directional forklift 602. Subsequently, the two flipping assemblies are driven to move away from each other by the double-directional lead screw module 401 until the two clamping plates 407 release the clamping of the cylinder head. Then, the telescopic ends of the cylinders 402 corresponding to the two flipping assemblies retract and reset, causing the two clamping plates 407 to move upward and reset. Next, the electric slide rail 3601 drives the double-directional forklift 602 to descend, causing the cylinder head on the lifting plate 603 to move downward until the bottom surface of the cylinder head is slightly higher than the top surface of the second cushion strip 604 in a storage bin 702 in a storage cabinet 701. Subsequently, the lifting plate 603 of the double-directional forklift 602 extends into the storage bin 702 of the storage cabinet 701, driving the cylinder head into the storage bin 702 until the bottom surface of the cylinder head completely covers the second cushion strip 604 in the storage bin 702. Then, the electric slide rail 3601 drives the double-directional forklift 602 to continue descending a small distance, causing the lifting plate 603 of the double-directional forklift 602 to drive the cylinder head to descend until the bottom surface of the cylinder head is supported by the second cushion strip 604 in the storage bin 702. Subsequently, the lifting plate 603 of the double-directional forklift 602 retracts and resets, preparing for the transfer of the next cylinder head. During the transfer of the unqualified cylinder head by the transfer mechanism 6, the electric slide rail 13 drives the loading plate 2 to continue moving leftward, causing the loading groove 202 of the loading plate 2 to extend outside the left side of the frame 1, repeating the above-mentioned cylinder head loading operation, and entering the inspection process of the next cylinder head to be inspected.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figures 2-5 shown, for an automobile cylinder head visual inspection device, support plates 8 are arranged on both the left and right sides of the upper part of the frame 1. The top surface of the support plate 8 is flush with the inner bottom surface of the inspection chamber 101. The top surface of the support plate 8 has two first cushion strips 801 parallel to the electric slide rail 13. The first cushion strips 801 are used to support the cylinder head. Two avoidance grooves 204 corresponding to the first cushion strips 801 are provided in both the loading groove 202 and the unloading groove 203 of the loading plate 2. The height of the top surface of the first cushion strip 801 is higher than the inner bottom surface height of the loading groove 202 and the unloading groove 203 of the loading plate 2. Two hydraulic cylinders 19 are vertically installed on both the front and rear sides of the frame 1. The telescopic rod ends of the hydraulic cylinders 19 face upward and are fixedly connected to the fixed ends of the electric slide rail 13 on the same side.

[0038] Working process of Embodiment 2: Place the cylinder head to be inspected on the first cushion strip 801 of the left support plate 8. Drive the material loading plate 2 to move leftward through the first electric slide rail 3, so that the loading groove 202 of the material loading plate 2 extends onto the left support plate 8. During this process, the first cushion strip 801 on the left support plate 8 enters the avoidance groove 204 of the loading groove 202. Synchronously drive the first electric slide rail 3 to move upward through multiple first hydraulic cylinders 9, so that the bottom surface of the loading groove 202 of the material loading plate 2 moves upward until the bottom surface of the loading groove 202 of the material loading plate 2 supports the cylinder head, and the bottom surface of the cylinder head is separated from the top surface of the first cushion strip 801 on the left support plate 8. Subsequently, drive the material loading plate 2 to move rightward into the inspection chamber 101 through the first electric slide rail 3 to perform the aforementioned appearance inspection operation. At this time, the next cylinder head to be inspected can be placed on the first cushion strip 801 on the left support plate 8. Then, when the unloading groove 203 of the material loading plate 2 extends onto the right support plate 8 with the qualified cylinder head, synchronously drive the first electric slide rail 3 to descend through multiple first hydraulic cylinders 9, so that the bottom surface of the unloading groove 203 of the material loading plate 2 descends until it contacts the top surface of the right support plate 8. During this process, the first cushion strip 801 on the right support plate 8 passes through the avoidance groove 204 of the unloading groove 203, and the qualified cylinder head in the unloading groove 203 of the material loading plate 2 is supported by the first cushion strip 801 on the right support plate 8. Subsequently, drive the material loading plate 2 to move leftward through the first electric slide rail 3, so that the unloading groove 203 moves out of the right support plate 8, and the loading groove 202 comes back to the left support plate 8 again, repeating the above cylinder head loading process. At the same time, the qualified cylinder head on the right support plate 8 can be taken away. In this way, the operator can place and take away the cylinder head on the first cushion strip 801 of the left and right support plates 8 without closely observing the movement of the material loading plate 2, reducing the possibility of mistakes by the operator during the intense operation.

[0039] In order to make the overall device structure more compact, in this Embodiment 2, as Figure 1 and Figure 2 shown, the support plate 8 is rotatably connected to the frame 1. There are two second hydraulic cylinders 10 connected between the lower part of the support plate 8 and the frame 1. The fixed end of the second hydraulic cylinder 10 is rotatably connected to the frame 1, and the telescopic rod end of the second hydraulic cylinder 10 is rotatably connected to the support plate 8. When not in use, the telescopic rod end of the second hydraulic cylinder 10 can be extended to make the support plate 8 rotate upward to close the connection channel between the inspection chamber 101 of the frame 1 and the outside, effectively saving storage space.

[0040] The above front, back, left, right, up, and down are all based on Figure 1 in the attached drawings of the specification. According to the standard of the observer's perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0041] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims described above.
