Description

Technical Field

[0001] This utility model belongs to the field of hemispherical production technology, specifically a surface inspection device for hemispherical production. Background Technology

[0002] A hemisphere typically refers to the industrial process of manufacturing hemispherical workpieces, which is widely used in optics, automotive, aerospace and other fields. Common materials for hemisphere production include glass, metal and plastic, and the processes include stamping, spinning, injection molding, grinding and polishing to ensure precision and surface finish.

[0003] Traditional hemispherical surface inspection equipment often uses continuous motion inspection or fixed angle inspection. In continuous motion, the image captured by the image acquisition instrument is prone to shift and blurring during the movement of the hemispherical workpiece. When fixed, the area of ​​the hemispherical surface obscured by the fixture cannot be exposed in the inspection field of view, which can easily form a blind spot and reduce the accuracy of the inspection data. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a surface inspection device for hemispherical production, which solves the problem that the image captured by the image acquisition instrument is easily shifted and blurred during the continuous movement of the hemispherical workpiece, and that the area of ​​the hemispherical surface that is blocked by the fixture when fixed cannot be exposed in the inspection field of view, which easily forms a blind spot and reduces the accuracy of the inspection data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface inspection device for hemispherical production, comprising a base, a worktable connected above the base, an electric push rod fixedly installed inside the base, a fixed frame connected to the base, an image acquisition device fixedly installed on the fixed frame, three guide grooves symmetrically arranged on the worktable, a clamping plate slidably installed on the worktable through the guide grooves, a groove at the center of the worktable, and a connecting shaft rotatably connected to the groove through a bearing;

[0006] One end of the connecting shaft is connected to a turntable, and the other end of the connecting shaft is connected to an intermittent wheel. The intermittent wheel has an arc-shaped groove on its edge and a push groove on its surface. A rotating rod is rotatably connected to the bottom of the worktable via a bearing. A disc is connected to the rotating rod. A connecting plate is connected to one side of the disc. A push block is connected below the connecting plate. An I-shaped block is connected below the clamping plate. An open plate is connected below the I-shaped block. Connecting grooves are provided on both sides of the open plate.

[0007] As a further embodiment of this utility model: a mounting plate is connected below the workbench, a motor is fixedly mounted on the mounting plate, the motor output shaft is connected to the rotating rod, the push block slides in the push groove, and the disc is in close contact with the arc groove.

[0008] As a further embodiment of this utility model: the turntable is disposed in the groove, the turntable has multiple sliding grooves, and an anti-slip pad is connected above the turntable.

[0009] As a further embodiment of this utility model: the sliding end of the electric push rod is connected to three support plates, and the three support plates are evenly distributed. A connecting rod is connected to the support plate, and the connecting groove is designed with an inclination and the connecting rod slides in the connecting groove.

[0010] As a further embodiment of this utility model: there are twelve sliding grooves distributed at equal intervals and with the same size as the guide grooves, and the narrow part in the middle of the I-shaped block slides in the guide grooves and sliding grooves.

[0011] As a further embodiment of this utility model: one end of the clamping plate is connected to a buffer pad, and both the buffer pad and the anti-slip pad are made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This surface inspection equipment for hemispherical production comprises an electric push rod, a support plate, a connecting rod, an open plate, a connecting groove, an I-shaped block, a guide groove, and a clamping plate. Activating the electric push rod pulls the support plate downwards. As the connecting rod slides within the connecting groove, the downward movement of the support plate causes the connecting rod to push against the open plate through the inclined wall of the connecting groove. This causes the open plate to move the I-shaped block along the guide groove and slide, thereby moving the three clamping plates towards the center of the turntable. This clamps and fixes the hemispherical workpiece. The synchronous movement of the three clamping plates pushes the hemispherical workpiece during clamping, keeping it centered and preventing displacement. This ensures stable surface image acquisition and improves inspection accuracy.

[0014] This surface inspection equipment for hemispherical production uses a motor, disc, connecting plate, pusher, intermittent wheel, arc groove, and push slot. The motor rotates the rotating rod, causing the disc to rotate and the pusher to slide into the push slot, which in turn pushes the intermittent wheel. The intermittent wheel drives the turntable to rotate via the connecting shaft, thus causing the turntable to rotate the hemispherical workpiece 90° intermittently. During this time, the disc slides in the arc groove, causing the turntable to stop intermittently, thus exposing the obscured part to the field of view of the image acquisition instrument. After the area is inspected, the rotation process is repeated, ultimately achieving full surface inspection of the hemispherical workpiece without manual adjustment. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a surface inspection device for hemispherical production, including a base 1, a worktable 2 connected above the base 1, an mounting plate 21 connected below the worktable 2, a motor 22 fixedly mounted on the mounting plate 21, the output shaft of the motor 22 connected to a rotating rod 14, a push block 17 sliding in a push groove 13, and a disc 15 in contact with an arc groove 12. By sliding the push block 17 in the push groove 13, the disc 15 can be rotated to push the intermittent wheel 11 to rotate the disc 10. Then the disc 15 will slide in the arc groove 12, thereby realizing the rotation adjustment and fixation of the hemispherical workpiece to achieve stable detection of the entire surface.

[0022] An electric push rod 3 is fixedly installed inside the base 1. The sliding end of the electric push rod 3 is connected to three support plates 25, and the three support plates 25 are evenly distributed. A connecting rod 26 is connected to the support plate 25. The connecting groove 20 is designed with an inclination and the connecting rod 26 slides in the connecting groove 20. Due to the inclination design of the connecting groove 20, the connecting rod 26 can push the groove wall of the connecting groove 20 when it moves up and down, causing the opening plate 19 to drive the clamping plate 7 to move. Thus, the clamping plate 7 is used to fix the hemispherical workpiece at multiple points and prevent the hemispherical workpiece from sliding and shifting.

[0023] A fixed frame 4 is connected to the base 1, and an image acquisition device 5 is fixedly installed on the fixed frame 4. Three guide grooves 6 are centrally symmetrically opened on the worktable 2. A clamping plate 7 is slidably installed on the worktable 2 through the guide grooves 6. A buffer pad 27 is connected to one end of the clamping plate 7. Both the buffer pad 27 and the anti-slip pad 24 are made of rubber. When the clamping plate 7 comes into contact with the hemispherical workpiece, the buffer pad 27 will be squeezed, thereby buffering the contact, avoiding bumps and scratches, and increasing friction to prevent slippage.

[0024] A groove 8 is provided at the center of the worktable 2. A connecting shaft 9 is rotatably connected to the groove 8 via a bearing. One end of the connecting shaft 9 is connected to a turntable 10. The turntable 10 is set in the groove 8. Multiple sliding grooves 23 are provided on the turntable 10, and an anti-slip pad 24 is connected above the turntable 10. The anti-slip pad 24 can increase the contact friction between the turntable 10 and the hemispherical workpiece, avoid accidental slippage, and enable the turntable 10 to drive the hemispherical workpiece to rotate and adjust.

[0025] The other end of the connecting shaft 9 is connected to an intermittent wheel 11. The intermittent wheel 11 has an arc-shaped groove 12 on its edge and a push groove 13 on its surface. A rotating rod 14 is rotatably connected to the bottom of the worktable 2 via a bearing. A disc 15 is connected to the rotating rod 14. A connecting plate 16 is connected to one side of the disc 15. A push block 17 is connected below the connecting plate 16. An I-shaped block 18 is connected below the clamping plate 7. An open plate 19 is connected below the I-shaped block 18. Connecting grooves 20 are provided on both sides of the open plate 19. There are twelve sliding grooves 23, which are evenly distributed and have the same size as the guide groove 6. The narrow part of the I-shaped block 18 slides in the guide groove 6 and the sliding grooves 23. Through the twelve equally distributed sliding grooves 23, the turntable 10 can be aligned with the guide groove 6 after completing a 90° intermittent rotation, thus facilitating the sliding of the I-shaped block 18 to achieve clamping and fixing of the clamping plate 7.

[0026] The working principle of this utility model is as follows:

[0027] The hemispherical workpiece is placed on the turntable 10. Then, the electric push rod 3 is activated to pull the support plate 25 downward, causing the connecting rod 26 to slide within the connecting groove 20. This pushes against the inclined wall of the connecting groove 20, causing the opening plate 19 to drive the I-shaped block 18 to slide along the guide groove 6 and the slide groove 23. This allows the three clamping plates 7 to clamp and fix the hemispherical workpiece. The first image is then captured by the image acquisition device 5. Afterward, the support plate 25 is pushed upward, causing the I-shaped block 18 to slide out of the slide groove 23 and into the guide groove 6. Finally, the motor 22 is activated to rotate the turntable 10. 5. The pusher 17 slides into the push groove 13 to push the intermittent wheel 11, which drives the turntable 10 to rotate. This causes the turntable 10 to rotate the hemispherical workpiece 90° intermittently. Then, the disc 15 slides in the arc groove 12, causing the turntable 10 to stop intermittently. This exposes the part that was covered during the first image capture to the field of view of the image acquisition instrument 5. The electric push rod 3 is then started again to clamp and position the hemispherical workpiece with the clamping plate 7. After the area is inspected, the rotation process is repeated to finally achieve full surface inspection of the hemispherical workpiece.
