Description

Technical Field

[0001] This invention relates to the field of defect detection technology, specifically to a defect detection device for stamped parts. Background Technology

[0002] As core components in manufacturing industries such as automotive, electronics, home appliances, and aerospace, the surface and structural integrity of stamped parts directly determines the performance, safety, and lifespan of end products. Visual defect detection, a crucial step in the entire stamped parts production process, empowers production from multiple dimensions, including cost control, safety compliance, efficiency improvement, and brand protection. However, existing stamped parts defect detection devices suffer from the following problems in use: For the inspection of stamped parts, a comprehensive circumferential inspection is required. Existing defect detection devices are not convenient for stable inspection of stamped parts of different specifications. In addition to clamping and positioning, circumferential position detection is also involved. How to ensure positioning and circumferential inspection when dealing with stamped parts of different specifications is an important factor affecting the inspection efficiency. At the same time, clamping and positioning involves the obstruction of contact surfaces. Existing stamped part defect detection devices are not convenient for comprehensive inspection of stamped parts. If the obstructed areas are not detected properly, it will seriously affect the quality of the finished product inspection.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0004] The purpose of this invention is to provide a defect detection device for stamped parts to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stamping part defect detection device, comprising a detection base, wherein a toothed roller is installed inside the detection base via a motor, and a toothed disc meshes on the inner side of the toothed roller; It also includes a mounting rod, which is laterally slidably installed in the top cavity of the gear plate via a first elastic telescopic rod. A pushing component is provided between the bottom of the mounting rod and the inside of the detection seat. The top of the mounting rod passes through the detection seat and is fixed with a mounting plate. A positioning plate is connected to the inner side of the mounting plate via a second elastic telescopic rod. A clearance component is provided between the positioning plate and the mounting plate. A placement seat is embedded and slidably installed in the top cavity of the middle part of the detection seat, and a lifting component is provided between the placement seat and the toothed disc; The detection component is located at the top edge of the detection seat and is used to take photographs to inspect the exterior of the stamped part.

[0006] Preferably, the mounting rod slides horizontally within the gear plate and the detection seat, and the mounting rod is distributed at equal angles on the gear plate.

[0007] Preferably, the pushing component includes a pushing seat, which is vertically and slidably embedded in the detection seat via an electric push rod.

[0008] Preferably, the top of the push seat has an annular structure that slides within the annular cavity at the bottom of the toothed disc, and the inner side of the top of the push seat and the outer side of the bottom of the mounting rod are mutually abutting inclined structures.

[0009] Preferably, the clearance component includes a crossbar, which is fixed to the outside of the positioning plate. The crossbar slides horizontally within the cavity in the middle of the mounting plate. A clearance groove is provided inside the crossbar, and a clearance rod is provided in the clearance groove. An abutment block is provided on the movement trajectory of the clearance rod, and the abutment block is fixed to the top of the detection seat.

[0010] Preferably, the outer side of the relief groove is configured as an inclined surface structure, and the relief groove is pushed outward by the relief rod to move the crossbar.

[0011] Preferably, the front cross section of the contact block is designed as a right-angled trapezoid with the inclined surface facing inward, and the side surface of the contact block is designed as an arc shape.

[0012] Preferably, the lifting assembly includes a first screw, which is threaded through the placement seat. A first gear is fixed to the bottom of the first screw. The outer side of the first gear meshes with a gear ring through a second gear. The first gear and the second gear are installed in the detection seat. The gear ring is fixed to the inner side wall of the gear disc.

[0013] Preferably, the detection assembly includes a column fixed to the top edge of the detection base, a second screw installed in the inner cavity of the column, a detection platform threaded onto the second screw, and a detection camera fixed to the inner end of the detection platform.

[0014] Preferably, the bottom of the second screw is connected to the toothed roller, and the detection camera is tilted downwards.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention places a stamped part on a placement plate. The upward movement of the pusher seat pushes the mounting rod to move laterally. The mounting plate and positioning plate circumferentially clamp and position the stamped part. A motor drives the toothed roller to rotate, causing the mounting rod, mounting plate, and positioning plate to rotate, thus rotating the stamped part. Simultaneously, the toothed roller drives the second screw to rotate, causing the downward-sloping inspection camera to gradually move downwards. This, combined with the rotation of the stamped part, allows for comprehensive inspection of its top and sides. Furthermore, the rotation of the toothed disc can also drive the placement plate upwards via the second screw, causing the stamped part to move upwards synchronously, greatly reducing inspection time and improving overall inspection efficiency. During this process, the position of the positioning plate can be adjusted by changing the upward movement distance of the pusher seat according to different specifications of the stamped part, allowing for positioning and clamping of stamped parts of different specifications without affecting the rotation of the stamped part driven by the toothed disc through the mounting rod and positioning plate, greatly increasing the practicality of the device. 2. In this invention, by setting a clearance component, when the positioning plate moves to the detection camera, the bottom vertical protrusion of the clearance rod contacts the arc surface of the abutment block, causing the clearance rod to move upward under force. By contacting the inclined side surface of the clearance groove, it pushes the crossbar and the positioning plate to move outward, exposing the stamping part position in that area. Meanwhile, the positioning plates in other areas still clamp the stamping parts, effectively improving detection efficiency and avoiding omissions. Furthermore, depending on the specifications of the stamping parts, the inner side of the top of the abutment block is inclined. By having the clearance rod contact different height areas of the abutment block, the crossbar and the positioning plate can move different distances. Thus, the clearance space and detection angle can be adjusted according to the specifications of the stamping parts, allowing the detection camera to better detect the bottom area of ​​the stamping parts, increasing practicality and improving detection results.

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

[0019] Please see Figures 1-5 The present invention provides a technical solution: a stamping part defect detection device, including a detection seat 1, a toothed roller 2 installed inside the detection seat 1 via a motor, and a toothed disc 3 meshing on the inner side of the toothed roller 2; a placement seat 11 is embedded and slidably installed in the top cavity in the middle of the detection seat 1, and a lifting component is provided between the placement seat 11 and the toothed disc 3. The mounting rod 5 is horizontally slidably installed in the top cavity of the gear plate 3 via the first elastic telescopic rod 4. A pushing component is provided between the bottom of the mounting rod 5 and the inside of the detection seat 1. The top of the mounting rod 5 passes through the detection seat 1 and is fixed with the mounting plate 7. The inner side of the mounting plate 7 is connected to the positioning plate 9 via the second elastic telescopic rod 8. The mounting rod 5 slides horizontally in the gear plate 3 and the detection seat 1. The mounting rod 5 is evenly distributed on the gear plate 3. The pushing component includes a pushing seat 61, which is vertically and slidably embedded in the detection seat 1 via an electric push rod 62; the top of the pushing seat 61 has a ring-shaped structure and is slidably disposed in the annular cavity at the bottom of the toothed disc 3; the inner side of the top of the pushing seat 61 and the outer side of the bottom of the mounting rod 5 are mutually abutting inclined structures. The stamped part to be tested is placed on the placement tray 12. According to the specifications of the stamped part, the pusher 61 is pushed upward by the electric push rod 62. The top of the ring-shaped pusher 61 contacts the bottom inclined surface of the mounting rod 5, pushing the mounting rod 5 to move inward. The pusher 61 with the ring-shaped top can always maintain contact with the bottom of the mounting rod 5. Multiple mounting rods 5 drive the mounting plate 7 to move. The positioning plate 9 contacts the stamped part to perform the positioning operation. The motor drives the toothed roller 2 to rotate, which drives the toothed disc 3 to rotate. In turn, the mounting rod 5 drives the mounting plate 7 and the positioning plate 9 to rotate, causing the stamped part to rotate. The rotation of the placement tray 12 on the placement seat 11 keeps it stable.

[0020] In one embodiment of the present invention, a detection component is disposed at the top edge of the detection seat 1. The detection component is used to take pictures of the outside of the stamped part for inspection. The detection component includes a column 141, which is fixed at the top edge of the detection seat 1. A second screw 142 is installed in the inner cavity of the column 141. A detection platform 143 is threaded on the second screw 142. A detection camera 144 is fixed at the inner end of the detection platform 143. The bottom of the second screw 142 is connected to the toothed roller 2. The detection camera 144 is tilted downward. The toothed roller 2 drives the second screw 142 to rotate, which in turn drives the inspection table 143 to move downward within the column 141. The downward-sloping inspection camera 144 performs a comprehensive inspection of the top and sides of the rotating stamped part.

[0021] In one embodiment of the present invention, a clearance component is provided between the positioning plate 9 and the mounting plate 7; the clearance component includes a crossbar 101, which is fixed to the outside of the positioning plate 9 and slides horizontally in the cavity in the middle of the mounting plate 7, so that the crossbar 101 can slide vertically in the cavity inside the mounting plate 7 under subsequent force; a clearance groove 102 is provided inside the crossbar 101, and a clearance rod 103 is provided in the clearance groove 102; an abutment block 104 is provided on the movement trajectory of the clearance rod 103, and the abutment block 104 is fixed to the top of the detection seat 1; the outside of the clearance groove 102 is set as a sloping structure, and the clearance groove 102 is pushed by the clearance rod 103 to move the crossbar 101 outward; the cross section of the abutment block 104 is designed as a right trapezoidal structure with the sloping surface facing inward, and the side of the abutment block 104 is designed as an arc structure; When the mounting plate 7 and the positioning plate 9 move to the area corresponding to the detection camera 144, the clearance rod 103 contacts the arc surface of the abutment block 104 located at the position of the detection camera 144. Under the force, the clearance rod 103 moves upward, and the top of the clearance rod 103 abuts against the inclined surface of the clearance groove 102, causing the crossbar 101 to move inward, so that the positioning plate 9 at this position separates from the stamping part, while the positioning plates 9 in other areas still maintain the clamping and positioning of the stamping part. Through the separation of the positioning plates 9, the detection camera 144 can take pictures and detect the stamping part in this area, avoiding the omission of detection.

[0022] As one embodiment of the present invention, the lifting assembly includes a first screw 131, which is threaded through the placement seat 11. A first gear 132 is fixed at the bottom of the first screw 131. The outer side of the first gear 132 meshes with a gear ring 134 through a second gear 133. The first gear 132 and the second gear 133 are installed in the detection seat 1. The gear ring 134 is fixed on the inner side wall of the gear disk 3. The rotation of the gear disk 3 can also drive the first screw 131 to rotate through the second gear 133 and the first gear 132, thereby driving the placement seat 11 to move upward synchronously, pushing the stamping part upward, and shortening the inspection time.

[0023] Working principle: First, the stamping part to be tested is placed on the placement plate 12. According to the specifications of the stamping part, the pusher 61 is pushed upward by the electric push rod 62. The top of the pusher 61 contacts the bottom inclined surface of the mounting rod 5, pushing the mounting rod 5 to move inward. Multiple mounting rods 5 drive the mounting plate 7 to move. The positioning plate 9 contacts the stamping part to perform the positioning operation. Then, the motor drives the toothed roller 2 to rotate, which drives the toothed disc 3 to rotate. In turn, the mounting rod 5 drives the mounting plate 7 and the positioning plate 9 to rotate, causing the stamping part to rotate. The rotation of the placement plate 12 on the placement seat 11 keeps it stable. Simultaneously, the toothed roller 2 drives the second screw 142 to rotate, causing the inspection table 143 to move downward within the column 141. The downward-tilting inspection camera 144 performs a comprehensive inspection of the top and sides of the rotating stamping. During this process, when the mounting plate 7 and the positioning plate 9 move to the area corresponding to the inspection camera 144, the clearance rod 103 contacts the arc surface of the contact block 104 located at the position of the inspection camera 144. Under the force, the clearance rod 103 moves upward, and the top of the clearance rod 103 contacts the inclined surface of the clearance groove 102, causing the crossbar 101 to move inward, so that the positioning plate 9 at this position separates from the stamping. The positioning plates 9 in other areas still maintain the clamping and positioning of the stamping. Through the separation of the positioning plates 9, the inspection camera 144 can take pictures and inspect the stamping in this area to avoid omissions in the inspection. Due to the influence of the arc height of the clearance rod 103, the separation distance of the positioning plate 9 can be adjusted according to the specifications of the stamping, so that the inspection camera 144 has a good inspection angle for stampings of different specifications. Furthermore, the rotation of the gear disk 3 can also drive the first screw 131 to rotate through the second gear 133 and the first gear 132, thereby driving the placement seat 11 to move upward synchronously, pushing the stamped part upward, and shortening the inspection time.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
