Description

Technical Field

[0001] This utility model relates to the field of detection and positioning technology, specifically a device for detecting and locating surface defects in stamped parts. Background Technology

[0002] As fundamental components in machinery manufacturing, automotive industry, and electronic equipment, the surface quality of stamped parts directly affects the assembly accuracy, performance, and service life of end products. During the stamping process, various factors such as raw material properties, die precision, and equipment parameter fluctuations can easily cause defects such as dents, scratches, burrs, and cracks on the surface of stamped parts. If these defects are not detected in time, they may lead to subsequent assembly failures, product scrap, or even safety hazards.

[0003] However, in actual use, most existing stamping surface defect detection devices often cannot adjust the position of the detection head, and most of them use detectors installed on both sides and the top of the machine to detect stamping parts. However, this method cannot be adapted to the detection of smaller stamping parts, and the detection effect is poor for smaller stamping parts. In view of this, we propose a stamping surface defect detection positioning device. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting and locating surface defects in stamped parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping part surface defect detection and positioning device, comprising a support leg and a support plate, wherein a conveyor belt is installed on the inner wall of the support leg, a detection box is fixedly connected to the upper surface of the support plate, a motor box is installed on the upper surface of the detection box, and a detection component is provided on the inner wall of the detection box;

[0006] The detection assembly includes an electric telescopic rod, the upper surface of which is fixedly connected to the upper side of the inner surface of the detection box. A fixed plate is fixedly connected to the lower surface of the output shaft of the electric telescopic rod. Rotating shafts are rotatably connected to both sides of the fixed plate. A swing plate is fixedly connected to the outer wall of the rotating shaft. Receiving boxes are fixedly connected to both sides of the front surface of the fixed plate. Insert blocks are slidably connected to the inner wall of the receiving boxes. A pull rod is fixedly connected to the side of the insert block away from the rotating shaft. A pull plate is fixedly connected to the side of the pull rod away from the insert block. Detectors are installed on the side of the fixed plate and the swing plate facing the conveyor belt. A slot is opened on the front side of the outer wall of the rotating shaft. The outer wall of the insert block is inserted into the inner wall of the slot. A pushing assembly is provided on the left surface of the detection box.

[0007] Preferably, the inner surface of the receiving box is elastically connected to the insert block by a support spring.

[0008] Preferably, the support plates are configured in two sets, and the two sets of support plates are mirror images of each other with the center line of the conveyor belt as the axis of symmetry. A material receiving component is provided on the right surface of the support plate set on the right side of the conveyor belt.

[0009] Preferably, a protective box is fixedly connected to the left surface of the detection box, and electric push rods are installed on both the front and rear sides of the right side of the inner surface of the protective box. A push plate is fixedly connected to the right surface of the output shaft of the electric push rod.

[0010] Preferably, the receiving assembly includes a collecting rack, the left surface of which is fixedly connected to the right surface of the support plate, and an extension baffle is fixedly connected to the upper surface of the collecting rack.

[0011] Preferably, a pull-out base plate is inserted into the lower inner wall of the collection rack. The pull-out base plate is L-shaped, and a handle is fixedly connected to the right surface of the pull-out base plate.

The handle is threadedly connected to the collection rack by fixing bolts.

[0013] Compared with the prior art, this utility model provides a device for detecting and locating surface defects in stamped parts, which has the following advantages:

[0014] 1. This stamping part surface defect detection and positioning device, through the detection component, allows the operator to control the extension and retraction of the electric telescopic rod, and simultaneously insert the insert block into different slots to accurately position the detector. Even when dealing with small stamping parts, the detector can accurately detect both sides of the stamping part by swinging the swing plate, and the telescopic rod can be extended to bring the detector closer to the stamping part, thereby achieving lower detection errors.

[0015] 2. This stamping part surface defect detection and positioning device, through the pushing component and the receiving component, allows the detector to release a signal to the electric push rod when it detects a dent or scratch on the surface of the stamping part. This controls the electric push rod to extend and push the defective material into the receiving component, thereby reducing labor costs. Furthermore, the pull-out bottom plate adopts a detachable design, allowing the operator to remove the entire pull-out bottom plate when picking up the stamping parts inside. At this time, the stamping parts can fall from below, making it convenient for the operator to dump the materials. Attached Figure Description

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a stamping part surface defect detection and positioning device, including a support leg 1 for supporting a conveyor belt 2 and a support plate 3 for supporting a detection box 4. The inner wall of the support leg 1 is equipped with a conveyor belt 2 for conveying stamping parts to the detection box 4 for detection. The upper surface of the support plate 3 is fixedly connected to a detection box 4 for supporting a detection component 8. The upper surface of the detection box 4 is equipped with a motor box 5 for controlling the extension and retraction of an electric push rod 62 and an electric telescopic rod 81. The inner wall of the detection box 4 is provided with a detection component 8 for detecting depressions and other defects on the surface of the material.

[0022] The detection assembly 8 includes an electric telescopic rod 81 for pushing the fixed plate 82 to move up and down. The upper surface of the electric telescopic rod 81 is fixedly connected to the upper side of the inner surface of the detection box 4. The lower surface of the output shaft of the electric telescopic rod 81 is fixedly connected to the fixed plate 82 for supporting the rotating shafts 83 on both sides. The left and right sides of the fixed plate 82 are rotatably connected to the rotating shafts 83 for driving the swing plate 84 to rotate. The outer wall of the rotating shaft 83 is fixedly connected to the swing plate 84 for changing the orientation and angle of the detector 85. The left and right sides of the front surface of the fixed plate 82 are fixedly connected to the receiving box 86 for accommodating the insert 87. The inner wall of the receiving box 86 is slidably connected to the insert. A block 87 is fixed inside the slot 811 to fix the rotating shaft 83. A pull rod 88 is fixedly connected to the side of the block 87 away from the rotating shaft 83 for easy pulling of the block 87. A pull plate 89 is fixedly connected to the side of the pull rod 88 away from the block 87 for easy pulling of the pull rod 88. A detector 85 for inspecting the surface of the stamped part is installed on the side of the fixed plate 82 and the swing plate 84 facing the conveyor belt 2. A slot 811 for accommodating the block 87 is opened on the front side of the outer wall of the rotating shaft 83. The outer wall of the block 87 is inserted into the inner wall of the slot 811. A pusher assembly 6 for pushing unqualified stamped parts to the receiving assembly 7 is provided on the left surface of the inspection box 4.

[0023] In one embodiment of this utility model, the inner surface of the receiving box 86 and the insert block 87 are elastically connected by a support spring 810 for driving the insert block 87 to reset. The support plate 3 is set in two sets, and the two sets of support plates 3 are mirror images of each other with the center line of the conveyor belt 2 as the axis of symmetry. The right surface of the support plate 3 on the right side of the conveyor belt 2 is provided with a receiving component 7 for collecting defective stamping parts. The left surface of the detection box 4 is fixedly connected with a protective box 61 for protecting the electric push rod 62 inside. Electric push rods 62 for driving the push plate 63 to move are installed on both the front and rear sides of the right side of the inner surface of the protective box 61. The right surface of the output shaft of the electric push rod 62 is fixedly connected with a push plate 63 for pushing defective materials to the receiving component 7.

[0024] In an embodiment of this utility model, the material receiving assembly 7 includes a collecting rack 71 for preventing stamped parts from falling out from all sides. The left surface of the collecting rack 71 is fixedly connected to the right surface of the support plate 3. An extension baffle 72 for extending the length to prevent materials from falling out from both sides is fixedly connected to the upper surface of the collecting rack 71. A pull-out bottom plate 73 for convenient handling of unqualified materials is inserted into the lower side of the inner wall of the collecting rack 71. The pull-out bottom plate 73 is L-shaped. A handle 74 for convenient handling of the pull-out bottom plate 73 is fixedly connected to the right surface of the pull-out bottom plate 73. Reinforcing plates 76 for strengthening the connection between the collecting rack 71 and the support plate 3 are fixedly connected to both the front and rear sides of the collecting rack 71. The opposite side of the reinforcing plate 76 and the position near the left side are fixedly connected to the outer wall of the support plate 3. The handle 74 and the collecting rack 71 are threadedly connected by fixing bolts 75 for fixing the collecting rack 71 and the pull-out bottom plate 73 together.

[0025] In this invention, during use, the operator places the stamped parts to be inspected in an orderly manner on the continuously running conveyor belt 2. The conveyor belt 2 is stably supported by the support legs 1, and its uniform movement sends the stamped parts sequentially into the inspection station directly below the inspection box 4 supported by the support plate 3. When the stamped parts move with the conveyor belt 2 to directly below the detector 85, they enter the pre-inspection state. Before or after the stamped parts are in place, the operator can adjust the irradiation angle of the detector 85 in the inspection assembly 8 in advance according to the specific shape of the stamped parts to be inspected and the surface areas that need to be focused on. During adjustment, by pulling the pull plate 89 outward, the pull rod 88 drives the insert block 87 to compress the support spring 810 and disengage it from the slot 811 on the rotating shaft 83, thereby releasing the lock on the rotating shaft 83. At this time, the operator can manually rotate the swing plate 84 to make it drive the detector 85 at the front end to rotate around the rotating shaft 83 to the optimal inspection angle. Once the angle is determined, the pull plate 89 is released, and the rebound force of the support spring 810 will push the insert 87 back into the corresponding slot 811 on the rotating shaft 83, thus reliably fixing the swing plate 84 and the detector 85. This design allows for independent asymmetrical adjustment of the detectors 85 on both sides of the fixed plate 82 to meet the detection needs of complex workpieces.

[0026] After the angle is adjusted and locked, the control center, located inside the motor housing 5, initiates the detection program. Upon receiving the signal, the electric telescopic rod 81 extends its push rod, pushing the fixed plate 82 and its entire detection mechanism—including the angled swing plate 84 and detector 85—downward until the detector 85 reaches the preset optimal working height from the stamped part surface. At this point, the detector 85, which may contain a vision camera, laser displacement sensor, or similar device, begins to operate, rapidly scanning and acquiring data from the surface of the stamped part stationary at the detection station. The acquired data is transmitted in real-time to the processing system and compared with preset standard parameters to accurately determine whether defects exist on the workpiece surface and their location.

[0027] After the inspection is completed, if the stamped part is deemed qualified, the conveyor belt 2 will restart and send it to the next process. If it is deemed unqualified, the control system will issue a command, and the electric push rod 62 located in the protective box 61 will move quickly. Its output shaft will extend to the right, driving the push plate 63 to move laterally. The push plate 63 will smoothly push the unqualified stamped part that is stuck at the inspection station off the conveyor belt 2 and make it fall into the receiving assembly 7 on the right. The unqualified stamped part pushed into the receiving assembly 7 falls into the collection area surrounded by the collection rack 71 and the extension baffle 72, and is temporarily stored on the L-shaped pull-out bottom plate 73. The reinforcing plate 76 ensures the stability of the connection between the collection rack 71 and the support plate 3. When cleaning is required, the operator only needs to loosen the fixing bolt 75 and pull the pull-out bottom plate 73 along with the waste material out of the collection rack 71 through the handle 74 for centralized processing. After completion, push it back and tighten the fixing bolt 75. The operation is very convenient.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
