Description

Technical Field

[0001] This utility model relates to the field of metal product technology, specifically to a double-sided inspection device for metal products. Background Technology

[0002] In the production process of metal products, metal pins, as basic and critical components, are widely used in many fields such as machinery manufacturing, automotive industry, and aerospace. Their quality directly affects the performance and safety of the entire product. In the traditional metal pin end inspection process, manual loading is the main method. Workers need to manually place the metal pins one by one on the inspection equipment. This process not only consumes a lot of manpower and time, but is also affected by factors such as worker fatigue and mood, making it difficult to maintain a high degree of consistency in the loading position and posture, resulting in large inspection errors. In terms of inspection methods, traditional methods are relatively simple, usually only able to inspect one end of the metal pin. If the other end needs to be inspected, the metal pin needs to be manually flipped and inspected again. This inspection method is not only inefficient, but also increases the workload of workers. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a double-sided inspection device for metal products, comprising an operating table, on which a rotating table is mounted, and a guide feeding assembly, a lifting and tilting assembly, and two sets of optical inspection devices are mounted around the rotating table. The two sets of optical inspection devices are respectively distributed on the left and right sides of the rotating table, and the guide feeding assembly and the lifting and tilting assembly are respectively distributed on the front and rear sides of the rotating table. Multiple bearing positions are mounted on the rotating table. The lifting and tilting assembly includes a support plate and a frame, and a lifting part is mounted on both the support plate and the frame. A pin and a lifting plate are respectively fixed at the top of the two lifting parts. A rotary electric gripper is mounted on the lifting plate, and the pin can extend into the bearing position.

[0004] Furthermore, the lifting portion on the support plate includes a lifting cylinder mounted on the support plate, and the piston rod of the lifting cylinder is fixed to the bottom of the lifting plate.

[0005] Furthermore, the bottom of the lifting plate can be attached to the top of the support plate.

[0006] Furthermore, the support plate is L-shaped, and a long waist hole is provided on the vertical plate of the support plate. An adjustment plate is fixed to the support plate by screws passing through the waist hole, and the lifting cylinder is installed on the adjustment plate.

[0007] Furthermore, the lifting part on the I-beam frame is an upper lifting cylinder, and the pin is fixed on the piston rod of the upper lifting cylinder.

[0008] Furthermore, an L-shaped guide plate is fixed on one side of the I-beam frame, and the upper lifting cylinder is mounted on the guide plate, with the piston rod of the upper lifting cylinder passing through the guide plate.

[0009] Furthermore, both the support plate and the I-beam frame have waist holes at their bottoms, and both the support plate and the I-beam frame are locked and fixed to the operating table by screws passing through these waist holes.

[0010] Furthermore, the guiding and feeding assembly includes a side plate, on which a guide block is fixed. The guide block has a material channel that can connect with an external feeding assembly and also with the material discharge area of ​​the bearing station. A side-push cylinder is also installed on the side plate. The piston rod of the side-push cylinder is fixed with a movable plate that is slidably connected to the cylinder body. A side-push plate is installed on the movable plate. A sealing plate that is in contact with the bottom of the guide block is fixed on the side of the side-push plate opposite to the guide block.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment of a double-sided inspection device for metal products includes an operating table 1, on which a rotating table 2 is installed. The rotating table 2 can rotate at a constant speed around its own central axis and can be driven by a stepper motor or a servo motor. Multiple sets of bearing stations 3 are installed on the rotating table. Each set of bearing stations 3 is used to place a single metal pin to be inspected, and the shape of the bearing station 3 is adapted to the metal pin to ensure that the metal product is placed stably.

[0020] The operating table 1 is also equipped with a guiding and feeding component 5, which is used to accurately guide the metal pins conveyed by the external feeding component to the bearing station 3 to realize automatic feeding.

[0021] The guiding and feeding assembly 5 includes a side plate 51 fixed on the operating table 1. A guide block 55 is fixed to the side plate 51 by bolts. A vertically penetrating material channel is opened on the guide block 55. The top of the material channel can be connected to an external feeding assembly, which can be a vibrating feeding plate. The other end faces the bearing position 3 of the rotating table 2. The inner diameter of the material channel is adapted to the outer diameter of the metal pin to be tested, ensuring that the metal pin can move smoothly along the material channel.

[0022] The side plate 51 has a side-push cylinder 52 fixed to its front side. The piston rod of the side-push cylinder 52 extends horizontally, and a moving plate 56 is fixed to the end of the piston rod. The moving plate 56 is slidably connected to the cylinder body of the side-push cylinder 52 to ensure stable horizontal movement of the moving plate 56. A side-push plate 53 is fixed to the side of the moving plate 56 near the guide block 55. A sealing plate 54 is fixed to the side of the side-push plate 53 opposite to the guide block 55. The sealing plate 54 is stepped, with its top abutting against the bottom of the guide block 55, and can block or open the bottom of the material channel of the guide block 55. A feeding hole is provided on the sealing plate 54. When the feeding hole is aligned with the material channel of the guide block 55, the material channel... The metal pins inside can fall into the bearing station 3 below through the feeding hole. When the sealing plate 54 moves to the point where the feeding hole and the material channel are misaligned, the bottom of the material channel is blocked, and the metal pins are temporarily stored in the material channel, realizing single-material feeding at a time and avoiding multiple materials falling into the bearing station 3 at the same time. The step of the sealing plate can play a limiting role when it contacts the guide block. Therefore, when the guide block is connected to the external feeding component, the external feeding component also feeds single materials and guides them into the guide block. Supported by the sealing plate, the material channel moves to the bottom of the guide block, and then the sealing plate is moved to make the feeding hole and the material channel of the guide block aligned to complete the feeding. After the feeding is completed, the sealing plate is misaligned again, and the external feeding component feeds the material into the guide block again. The cycle operation is completed to complete the feeding.

[0023] In addition, to limit the travel of the moving plate 56, a stop block 58 is fixed to the top of the side thrust cylinder 52. A screw 59 is threaded onto the stop block 58 in the horizontal direction. A top block 57 is fixed to the top of the moving plate 56, and the top block 57 is coaxial with the screw 59. By rotating the screw 59, the extension length of the screw 59 can be adjusted, thereby limiting the maximum travel distance of the moving plate 56. The moving plate 56 stops when the top block 57 contacts the screw 59.

[0024] like Figure 1 The operating table 1 is also equipped with optical inspection devices 4 distributed on the left and right sides of the rotating table 2. Each set of optical inspection devices 4 includes an industrial camera, a light source and an image analysis module, which can collect images of the top of the metal pin to complete the diameter detection. The right optical inspection device 4 is used to detect the top of the metal pin, and the left optical inspection device 4 is used to detect the bottom of the metal pin.

[0025] like Figure 3 The operating table 1 is equipped with a lifting and flipping component 6 that is distributed opposite to the guiding and feeding component 5. It is used to lift and flip the metal pins that have passed the first inspection in preparation for the second inspection.

[0026] The lifting and flipping assembly 6 includes a support plate 61 and a frame 66 fixed on the operating table 1. The support plate 61 is L-shaped, with a long, narrow hole along the vertical direction on its upright plate. An adjusting plate 62 is fixed to the upright plate of the support plate by screws passing through the long, narrow hole. The height of the adjusting plate 62 can be adjusted by loosening the screws and moving the adjusting plate 62 up and down. A lifting cylinder 63 is fixed on the adjusting plate 62. The piston rod of the lifting cylinder 63 extends vertically, and a lifting plate 64 is fixed to the top of the piston rod. A rotary electric gripper 65 is fixed to the top of the lifting plate 64. The gripper of the rotary electric gripper 65 can open and close horizontally to hold a metal pin. The rotary electric gripper 65 can drive the metal pin to rotate 180° around the vertical axis to switch between the front and back sides. When the piston rod of the lifting cylinder 63 is fully retracted, the bottom of the lifting plate 64 is in contact with the top of the support plate 61, ensuring that the initial position of the lifting plate 64 is stable.

[0027] Additionally, an L-shaped guide plate 69 is fixed to the back of the I-beam frame 66. An upper-lifting cylinder 67 is fixed on the guide plate 69. The piston rod of the upper-lifting cylinder 67 extends vertically and passes through the guide plate 69. The guide plate 69 guides the piston rod to prevent it from tilting. A pin 68 is fixed to the top of the piston rod. The axis of the pin 68 is aligned with the center of the bearing station 3. The diameter of the pin 68 is smaller than the inner diameter of the metal pin, ensuring that the pin 68 can stably lift the metal pin. When the bearing station moves the rotating metal pin above the pin, the upper-lifting cylinder first drives the pin to lift the metal pin. At this time, the metal pin is located between the jaws of the rotary electric gripper and is clamped and fixed. Then, the lifting cylinder lifts it to a certain height and separates it from the bearing station. Then, the rotary electric gripper rotates 180 degrees to complete the flip. At this time, the lifting cylinder and the upper-lifting cylinder retract.

[0028] Meanwhile, the bottom of both the support plate 61 and the I-beam frame 66 is provided with waist holes. Both are locked and fixed to the operating table 1 by screws passing through the corresponding waist holes. After loosening the screws, the position of the support plate 61 and the I-beam frame 66 can be adjusted along the direction of the waist holes, thereby adjusting the relative position of the rotating electric gripper 65 and the pin 68 to ensure accurate positioning.

[0029] The working principle of the above embodiments is as follows:

[0030] After the equipment starts, the external vibrating feeder orderly conveys the metal pins to be tested to the guide block of the feeding assembly. The metal pins slide down the vertically penetrating channel on the guide block. At this time, the sealing plate is in the bottom sealing state of the channel, and the metal pins are temporarily stored in the channel. When the rotary table, driven by the stepper motor or servo motor, drives a set of unloaded bearing positions to rotate directly below the guide block, the side push cylinder is activated. Its piston rod pushes the moving plate to move the guide block horizontally. The moving plate drives the side push plate and the sealing plate to move synchronously. When the discharge hole on the sealing plate is aligned with the channel of the guide block, the metal pins in the channel fall accurately into the bearing position below through the discharge hole, realizing single-piece feeding and avoiding multiple pieces falling in at the same time. After the feeding is completed, the piston rod of the side push cylinder retracts, driving the sealing plate to reset, and the feeding is completed. The hole and the material channel are misaligned, and the bottom of the material channel is resealed, awaiting the next feeding. During this process, the extension length can be adjusted by rotating the screw on the stop block. When the top block of the moving plate abuts against the screw, the moving plate stops moving, thus precisely limiting the maximum moving distance of the moving plate and ensuring the alignment accuracy between the feeding hole and the bearing station. The bearing station, which completes the feeding, rotates at a constant speed with the rotary table. When it moves to the optical detection device on the right side of the operating table, the rotary table stops rotating, and the light source of the optical detection device on the right side is activated, providing sufficient and uniform illumination to the tip of the metal pin. The industrial camera acquires an image of the tip of the metal pin, and the acquired image is transmitted to the image analysis module. The module calculates the diameter of the tip of the metal pin using image algorithms, completing the first inspection and recording the inspection data. After the first inspection, the rotary table restarts, rotating the bearing station and metal pin to the lifting and tilting assembly. At this point, the bearing station is directly above the pin. First, the upper lifting cylinder activates, its piston rod extending vertically upwards, causing the pin to rise synchronously. The pin passes through the gap in the bearing station, lifting the metal pin so that the top of the pin protrudes from the bearing station and is positioned precisely between the jaws of the rotary electric gripper. Then, the jaws of the rotary electric gripper close horizontally, stably holding the metal pin. Next, the lifting cylinder activates, its piston rod extending upwards, causing the lifting plate and rotary electric gripper to rise synchronously, completely removing the metal pin from the bearing station. Once the metal pin reaches a safe height, the rotary electric gripper activates, rotating the metal pin 180 degrees around its vertical axis. The metal pin is switched between its front and back sides at a certain angle to prepare for the second inspection. After flipping, the piston rod of the lifting cylinder retracts, causing the metal pin to descend until it falls back into the bearing position. The rotary electric gripper opens and resets, while the piston rod of the upper cylinder retracts, causing the pin to descend and reset. If it is necessary to adjust the height or horizontal position of the rotary electric gripper and the pin, the screws on the support plate can be loosened, and the adjusting plate can be moved up and down to adjust the height of the lifting cylinder and the rotary electric gripper. Alternatively, the screws on the support plate and the bottom of the I-beam can be loosened, and the two can be moved along the direction of the waist hole to ensure the precise relative position of the rotary electric gripper and the pin. The flipped metal pin continues to rotate with the rotating table along with the bearing position. When it moves to the optical inspection device on the left side of the operating table, the rotating table stops rotating.The optical inspection device on the left repeats the inspection action on the right. The light source is activated, and the industrial camera acquires an image of the bottom of the metal pin. The image analysis module calculates the diameter of the bottom of the metal pin, completing the second inspection and recording the inspection data. After both inspections are completed, the rotary table continues to rotate, conveying the inspected metal pin to the subsequent sorting or unloading station. Simultaneously, a new empty loading station moves to the loading position, and the equipment enters the next inspection cycle, achieving continuous automated inspection.
