Description

Technical Field

[0001] This utility model relates to the field of detection devices, and in particular to a clamping mechanism and a detection device. Background Technology

[0002] Existing detection systems primarily identify objects by acquiring multiple images of the object's surface, then using algorithms to determine if defects exist. Typically, after the object is transported to a designated location, an image recognition device acquires images of its surface. A rotating mechanism then drives the object to rotate a certain angle, and another image recognition device acquires images of the surface. However, this approach limits the angle at which the image recognition device can acquire the detection surface, and the discontinuous nature of the detection surface necessitates multiple detections. Furthermore, the transport and detection of the object cannot be synchronized, resulting in long detection times. Utility Model Content

[0039] like Figure 1-2 A clamping mechanism for a detection device includes: a clamping drive unit 51 and a clamping adjustment assembly 53;

[0040] The clamping drive units 51 are arranged in pairs; each clamping drive unit 51 includes: a clamping rotation driver 511, a clamping drive wheel 512, a clamping driven wheel 513, and a clamping timing belt 514.

[0041] The output end of the clamping rotation driver 511 is connected to the clamping drive wheel 512 and is used to drive the clamping drive wheel 512 to rotate; the clamping timing belt 514 connects the clamping drive wheel 512 and the clamping driven wheel 513 to rotate synchronously.

[0042] The clamping adjustment assembly 53 includes: a clamping head 531;

[0043] The clamping synchronous belt 514 is movably limited to the clamping head 531; the clamping head 531 causes a section of the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 to shift outward in the direction of the outer circle, forming an offset section 5140; the offset sections 5140 of two adjacent clamping drive units 51 are close together and form a clamping jaw 510 with clamping function.

[0044] This solution provides a clamping mechanism for a detection device. The clamping head 531 causes the offset section 5140 to shift outward. The clamping timing belt 514 forms a jaw to hold the object to be detected. The clamping timing belt 514 drives the object to rotate a specific number of revolutions during the movement, allowing the object to be detected while rotating. This achieves multi-faceted detection and solves the problems of incomplete, inaccurate, and time-consuming detection caused by the limited or discontinuous rotation angle of the object in existing detection devices.

[0045] Specifically, the clamping drive units 51 are arranged in pairs, each clamping drive unit 51 having a corresponding clamping drive wheel 512 and a clamping driven wheel 513, which are connected by a clamping timing belt 514 to rotate synchronously. The clamping drive wheel 512 and / or the clamping driven wheel 513 can be mounted on a known frame structure, plate structure, etc., such as the detection base 06. The clamping drive wheel 512 of one or both clamping drive units 51 is mounted on the output end of the clamping rotation driver 511. When the clamping rotation driver 511 is started, the output end of the clamping rotation driver 511 drives the clamping drive wheel 512 to rotate, synchronized with the clamping timing belt 514. Under the action of the clamping head 531, the driven wheel 513 is driven to rotate, thereby causing the clamping synchronous belt 514 to rotate, and finally causing a section of the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 to move. At the same time, the section of the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 is limited to the clamping head 531. The clamping head 531 can cause the section of the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 to shift towards the outer ring of the clamping synchronous belt 514, so that the shifted section deviates from the straight line formed by the wheel surfaces of the clamping driving wheel 512 and the clamping driven wheel 513. The clamping head 531 also has a tensioning effect on the clamping synchronous belt 514. When the object to be tested is conveyed to the jaw formed between the two clamping synchronous belts 514, the output end of the clamping rotation driver 511 drives the clamping drive wheel 512 to rotate, which in turn drives the clamping synchronous belts 514 to rotate. Under the action of the rotating clamping synchronous belts 514, the object to be tested moves and rotates, and when a speed difference is formed between the two clamping synchronous belts 514, the object to be tested can rotate one or more times. Specifically, this can be determined by the distance the clamping head 531 deviates the clamping synchronous belts 514 outwards. The speed difference between the clamping synchronous belts 514 can be achieved based on the output parameters of the clamping rotation driver 511 of the corresponding clamping drive unit 51. In this way, the object to be tested can move through the detection device with multiple faces while rotating, and the detection device can identify multiple faces of the object at once. The jaw 510 has both rotational and linear conveying functions, thereby improving detection accuracy and reducing detection waiting time. This solves the problems of incomplete, inaccurate, and time-consuming detection caused by the limited or discontinuous rotation angle of the object to be tested in existing detection devices.

[0046] The clamping rotation driver 511 is a known mechanism with a drive rotation function, such as a motor.

[0047] Optimally, it also includes: a clamping motion driver 532;

[0048] The output of the clamping motion driver 532 is used to drive the clamping drive unit 51 to move towards or away from each other, thereby moving the offset segment 5140.

[0049] The two offset segments 5140 move relative to each other, either one towards the other or both towards each other. When the two offset segments 5140 move towards each other, they come together to form a clamping jaw 510 with a clamping function. The size of the clamping jaw 510 can be adjusted according to the clamping movement driver 532, thereby adaptively clamping different sizes of objects to be detected.

[0050] Alternatively, the clamping drive unit 51 may further include: a detection base 06;

[0051] The clamping rotation driver 511, the clamping drive wheel 512, and the clamping driven wheel 513 are respectively mounted on the detection base 06; the output end of the clamping movement driver 532 is connected to the detection base 06 or the clamping head 531, and is used to drive the detection base 06 or the clamping head 531 to move, thereby driving the offset segment 5140 to move.

[0052] In one embodiment, the clamping motion driver 532 can drive the detection base 06 to move, thereby causing the clamping rotation driver 511, the clamping drive wheel 512, the clamping driven wheel 513, and the clamping timing belt 514 to move synchronously, causing the offset segment 5140 of the clamping timing belt 514 to move, thereby adjusting the size of the clamping jaw 510. In another embodiment, the clamping motion driver 532 can drive only the clamping head 531 to move, thereby driving the offset segment 5140 to move through the clamping head 531 to adjust the size of the clamping jaw 510.

[0053] Further optimized, the clamping motion driver 532 includes: a clamping drive seat 5321 and a clamping drive screw 5322;

[0054] The clamping drive screw 5322 is rotatably mounted on the clamping drive base 5321; the clamping head 531 or the detection base 06 is threadedly engaged with the clamping drive screw 5322; the rotation of the clamping drive screw 5322 drives the clamping head 531 or the detection base 06 to move.

[0055] The clamping motion driver 532 in this solution can be a known mechanism with driving movement function, such as a mobile trolley, conveyor belt structure, or robotic arm, as long as it can drive the clamping drive unit 51 or the clamping head 531 to move. This solution preferably uses the cooperation between the clamping drive screw 5322 and the clamping drive seat 5321 as the clamping motion driver 532. The clamping drive screw 5322 is rotatably mounted on the clamping drive seat 5321. When the clamping drive screw 5322 is rotated, the threaded structure between the clamping drive screw 5322 and the clamping head 531 (or the detection base 06) moves relative to each other. The movement of the clamping head 531 will drive the offset segment 5140 to move, causing the offset segment 5140 to move relative to the clamping jaw 510 to open or close; or the detection base 06 will drive the entire clamping drive unit 51 to move, thereby driving the offset segment 5140 to move relative to the clamping jaw 510 to open or close.

[0056] Optimally, the clamping drive screw 5322 is provided with a first drive thread section 53221 and a second drive thread section 53222 in opposite directions;

[0057] The first drive thread segment 53221 is threadedly engaged with one of the clamping heads 531 or detection bases 06 of the clamping synchronous belt 514, and the second drive thread segment 53222 is threadedly engaged with the other clamping head 531 or detection base 06 of the clamping synchronous belt 514.

[0058] This solution can drive two clamping heads 531 (or detection base 06) to move relative to each other through a single clamping drive screw 5322, thereby driving the clamping jaws 510 formed by the two clamping timing belts 514 to open or close through a single drive source. The rotation of the clamping drive screw 5322 can be adjusted manually or automatically (e.g., by using a motor drive). The rotation of the clamping drive screw 5322 drives the first drive thread segment 53221 and the second drive thread segment 53222 to rotate. Since the first drive thread segment 53221 and the second drive thread segment 53222 are in opposite directions, one is a right-hand thread and the other is a left-hand thread, the clamping drive screw 5322 can rotate clockwise to move the two clamping heads 531 (or the detection base 06) towards each other, thereby moving the clamping timing belt 514 towards each other until the clamping jaw 510 contracts. When the clamping drive screw 5322 rotates counterclockwise, the two clamping heads 531 (or the detection base 06) can rotate away from each other, thereby moving the clamping timing belt 514 towards each other until the clamping jaw 510 opens.

[0059] Alternatively, the clamping adjustment assembly 53 may further include: a clamping guide rod 533;

[0060] The two ends of the clamping guide rod 533 are respectively movably mounted on the clamping head 531 that connects to different clamping timing belts 514, and the clamping head 531 moves along the length direction of the clamping guide rod 533.

[0061] One end of the clamping guide rod 533 is movably connected to one of the clamping heads 531, and the other end of the clamping guide rod 533 is movably connected to the other clamping head 531. Thus, when the two clamping heads 531 (or the detection base 06) move toward or away from each other, the clamping head 531 (or the detection base 06) can drive the offset section 5140 to move along the length direction of the clamping guide rod 533, thereby making the clamping timing belts 514 of the two clamping drive units 51 move on the same plane, so that the clamping jaw 510 can be fixed in a specific position and maintain clamping stability.

[0062] Alternatively, the clamping motion driver 532 may further include: a screw handle 5323;

[0063] The screw handle 5323 is mounted on the clamping drive screw 5322 and is used to drive the clamping drive screw 5322 to rotate.

[0064] This solution allows manual adjustment of the clamping drive screw 5322 using the screw handle 5323, thereby controlling the opening and closing of the clamp.

[0065] Alternatively, the clamping head 531 may be provided with a clamping limiting groove 5311; the offset segment 5140 may be relatively movably limited within the clamping limiting groove 5311.

[0066] The clamping limiting groove 5311 can limit the movement of a section of the clamping synchronous belt 514, thereby ensuring that when the clamping synchronous belt 514 rotates, the section between the clamping driving wheel 512 and the clamping driven wheel 513 can move along the length direction of the clamping limiting groove 5311. This provides guidance for the movement of this section of the clamping synchronous belt 514, ensuring that the object to be detected moves along the length direction of the clamping limiting groove 5311 while being clamped, thus improving movement stability. At the same time, when the clamping head 531 moves, it can drive the offset section 5140 to move towards the object to be detected through the clamping limiting groove 5311, thereby reducing the clamping opening 510 formed by the clamping synchronous belt 514. This ensures that the clamping synchronous belt 514 is always confined within the clamping limiting groove 5311 and is not easily dislodged.

[0067] A detection device is provided with the clamping mechanism of the detection device described above.

[0068] Optimally, it also includes: an image acquisition device 54;

[0069] The image acquisition device 54 is disposed between the clamping drive wheel 512 and the clamping driven wheel 513, and the lens of the image acquisition device 54 is oriented toward the offset segment 5140.

[0070] The image acquisition device 54 is a known image acquisition mechanism, such as an industrial camera, a regular camera, or a video recorder. The image acquisition device 54 is positioned between the clamping drive wheel 512 and the clamping driven wheel 513, and can acquire images of the object being inspected as it passes through the offset section 5140. The object being inspected moves through the image acquisition device 54 in a rotating state under the clamping action of the clamp 510, thus facilitating the image acquisition device 54 to determine whether there is a defect based on the continuous inspection images of the object being inspected in one go. This solves the problem of incomplete, inaccurate, and time-consuming inspections caused by the limited or discontinuous rotation angle of the object being inspected in existing inspection devices.
