DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-11 The embodiment of the present invention provides a thermal film defect detection device based on machine vision, comprising a bottom plate 1 and a detection plate 2 fixedly arranged on the top of the bottom plate 1, two fixed side plates 3 are fixedly connected to the top of the bottom plate 1, a thermal film 7 is arranged on the top of the detection plate 2, two detection heads 8 are fixedly connected to the tops of the two fixed side plates 3, and a clamping member is slidably arranged in the middle of the two fixed side plates 3, and the clamping member is used to clamp the thermal film 7; A fixing plate 407 is fixedly connected to the top of the bottom plate 1, and a flipping piece is provided on one side of the fixing plate 407 close to the fixing side plate 3, and the flipping piece is used to flip the clamping piece to flip the thermal film 7; Two pushers are symmetrically arranged inside a fixed side plate 3 close to the fixed plate 407 , and the pushers are used to push the thermal film 7 .

[0020] In the above technical solution, the pushing of the thermal film 7 by the pushing member ensures that the detection of the thermal film 7 is not blocked by the transportation device during transportation, thereby ensuring the complete detection of the entire plane of the thermal film 7, avoiding the local defects of the thermal film 7 not being detected, and ensuring the quality rate of the thermal film 7. The flipping action of the flipping member on the clamping member flips the clamped thermal film 7, so that both sides of the thermal film 7 can be detected, ensuring the integrity of the detection of the thermal film 7. At the same time, the flipping member controls the pushing member, so that the detection device can run automatically, simplifying the operating process of the operator and reducing the complexity of the operation of the detection device.

[0021] Specifically, the flip part includes a sliding column 401, which is slidably connected to the middle part of the fixed side plate 3 near the fixed plate 407, and one end of the sliding column 401 near the fixed plate 407 is fixedly connected to a half gear 402, and the top of the base plate 1 is fixedly connected to a caliper plate 403, and the caliper plate 403 is clamped with the half gear 402, and the side of the half gear 402 away from the sliding column 401 is fixedly connected to a rotating connecting block 404, and the other end of the rotating connecting block 404 is rotatably connected to a connecting column 405, and the other end of the connecting column 405 is fixedly connected to a sliding groove column 406.

[0022] In the above technical solution, by the clamping connection between the half gear 402 and the caliper plate 403, it is achieved that the sliding rotating column 401 can reciprocate and rotate at the same time through the sliding connection rotating column 405.

[0023] Specifically, the side of the fixed plate 407 close to the sliding connecting column 410 is fixedly connected to the rotating motor 408, the other end of the rotating motor 408 is fixedly connected to the rotating connecting column 409, the side of the rotating connecting column 409 away from the rotating motor 408 is rotatably connected to the sliding connecting column 410, and the sliding connecting column 410 is slidably connected to the inside of the sliding slot column 406.

[0024] In the above technical solution, by sliding the sliding connecting column 410 inside the sliding slot column 406 , the sliding slot column 406 is driven to reciprocate by the rotation of the rotating motor 408 , thereby realizing the reciprocating motion of the connecting rotating column 405 .

[0025] Specifically, each pushing member includes a pushing slide 501, which is slidably connected to the middle part of the fixed side plate 3, and a pushing angle 502 is fixedly connected to the side of the pushing slide 501 away from the sliding rotating column 401, and a sliding angle 503 is slidably connected to the side of the pushing slide 501 away from the pushing angle 502, and a connecting limit plate 504 is fixedly connected to the side of the sliding angle 503, and a return spring 505 is fixedly connected to one side of the connecting limit plate 504, and the other end of the return spring 505 is fixedly connected to the inside of the pushing slide 501.

[0026] In the above technical solution, the push slide 501 drives the push clamping angle 502 and the sliding clamping angle 503 to move, thereby driving the thermal film 7 to move, while ensuring that a plane of the thermal film 7 is not blocked and can be completely detected by the detection head 8.

[0027] Specifically, one end of the push slide 501 away from the push clamping angle 502 is rotatably connected to the connecting plate 506, and the side of the connecting plate 506 away from the sliding clamping angle 503 is fixedly connected to the reset slide 507, the middle part of the reset slide 507 is rotatably connected to the push rotating plate 508, the reset slide 507 is slidably connected to the inside of the fixed side plate 3, and the bottom of the reset slide 507 is fixedly connected to the push spring 509, and the other end of the push spring 509 is fixedly connected to the inside of the bottom plate 1.

[0028] In the above technical solution, through the mutual movement of the reset slide 507 and the push turn plate 508, and the elastic stretching action of the push spring 509, the movement of the flip clamp 601 can drive the movement of the push slide 501, thereby realizing the reciprocating motion of the push slide 501, and then realizing the automated transportation of the thermal film 7.

[0029] Specifically, the clamping member includes a flip clamp 601, which is fixedly connected to one end of the sliding column 401 away from the half gear 402, and a side of the flip clamp 601 away from the sliding column 401 is fixedly connected to a limiting slide 605, and the limiting slide 605 is slidably connected to the middle part of a fixed side plate 3 away from the fixed plate 407.

[0030] In the above technical solution, the sliding restriction of the limit slide post 605 ensures the reciprocating motion and rotation of the flip clamp 601, thereby realizing the transportation of the thermal film 7.

[0031] Specifically, two connecting clamp columns 602 are fixedly connected to the top of the flip clamp 601, and the middle parts of the two connecting clamp columns 602 are rotatably connected to the clamp rotating plate 603. Both sides of the clamp rotating plate 603 are fixedly connected to the torsion spring 604, and the other end of the torsion spring 604 is fixedly connected to the middle part of the flip clamp 601.

[0032] In the above technical solution, the clamping plate 603 can contact the side of the thermal film 7 under the elastic torsion action of the torsion spring 604, thereby clamping the thermal film 7.

[0033] Specifically, a sliding limit column 411 is fixedly connected to one side of the sliding slot column 406 away from the rotating connecting column 409 , and the sliding limit column 411 is slidably connected to the middle part of the fixed side plate 3 .

[0034] In the above technical solution, the sliding limit column 411 slides inside the fixed side plate 3, so that the sliding slot column 406 cannot rotate, thereby ensuring the reciprocating rotation of the sliding slot column 406 and the transmission of the flip member.

[0035] Specifically, the working principle and operation method of the present invention are as follows: When not in use, the half gear 402 is engaged with the caliper plate 403, the sliding rotating column 401 is located in the middle of the fixed side plate 3, the sliding connecting column 410 is slidably connected to the top of the sliding slot column 406, and the sliding clamping angle 503 is in contact with the side of the fixed side plate 3, thereby putting the reset spring 505 in a stretched state, and the clip rotating plate 603 tilts toward the inside of the flip clamp 601.

[0036] When in use, the operator puts the thermal film 7 between the push clamping angle 502 and the sliding clamping angle 503, and starts the rotating motor 408. The rotating motor 408 drives the rotating connecting column 409 to rotate, and then drives the sliding connecting column 410 to make a circular motion around the rotating motor 408. At this time, the sliding groove column 406 can only move linearly in the direction close to and away from the thermal film 7 under the restriction of the sliding limit column 411. Therefore, as the rotating connecting column 409 rotates in the direction close to the thermal film 7, the sliding connecting column 410 makes a circular motion in the direction close to the thermal film 7. The sliding groove column 406 moves in a circle, thereby driving the sliding groove column 406 to move toward the direction close to the thermal film 7. At the same time, the sliding connecting column 410 slides from the top of the sliding groove column 406 to the bottom of the sliding groove column 406. The sliding groove column 406 drives the connecting rotating column 405 to move toward the direction close to the thermal film 7, and then drives the half gear 402 to move toward the direction close to the thermal film 7 by rotating the connecting block 404. The half gear 402 drives the sliding rotating column 401 to move toward the direction close to the thermal film 7, and then drives the flip clamp 601 to move toward the direction close to the thermal film 7.

[0037] At the same time, since the half gear 402 is engaged with the caliper plate 403, as the half gear 402 moves toward the direction approaching the thermal film 7, the half gear 402 will rotate at the same time, and then drive the flip clamp 601 to rotate toward the direction approaching the thermal film 7 through the sliding rotating column 401, and the flip clamp 601 drives the clamp rotating plate 603 to rotate toward the direction approaching the thermal film 7 through the connecting clamp column 602. As the half gear 402 further moves toward the direction of the thermal film 7, the half gear 402 and the caliper plate 403 are no longer engaged, and the half gear 402 stops rotating. At this time, the flip clamp 601 maintains a horizontal state and further moves toward the direction approaching the thermal film 7.

[0038] At this time, as the sliding rotating post 401 moves toward the direction approaching the thermal film 7, the sliding rotating post 401 contacts the end of the pushing rotating plate 508 away from the reset sliding post 507, thereby pushing the pushing rotating plate 508 to move toward the reset sliding post 507. Since the other end of the pushing rotating plate 508 is rotatably connected to the reset sliding post 507, the reset sliding post 507 is slidably connected to the inside of the fixed side plate 3 and is restricted to slide only upward or downward. Therefore, as the pushing rotating plate 508 moves away from one end of the reset sliding post 507, the other end of the pushing rotating plate 508 moves downward, thereby driving the reset sliding post 507 to move downward and compressing the pushing spring 509. The reset sliding post 507 drives the end of the connecting plate 506 close to the reset sliding post 507 to move downward.

[0039] Since the other end of the connecting plate 506 is rotatably connected to one end of the push slide 501, the push slide 501 is restricted by the fixed side plate 3 and can only slide in a straight line. Therefore, as the connecting plate 506 moves downward close to one end of the reset slide 507, the connecting plate 506 drives the push slide 501 to slide in the direction close to the sliding rotation column 401. The push slide 501 drives the thermal film 7 to move in the direction close to the sliding rotation column 401 through the pushing clamping angle 502 and the sliding clamping angle 503, thereby moving the thermal film 7 to the bottom of the detection head 8 to complete the detection of one side.

[0040] At this time, the push slide post 501 slides in the direction close to the sliding rotation post 401, thereby driving the sliding clamping angle 503 to move in the direction close to the sliding rotation post 401, and finally the sliding clamping angle 503 no longer conflicts with the fixed side plate 3. Under the elastic extension action of the return spring 505, the connecting limit plate 504 moves in the direction close to the fixed side plate 3, and the connecting limit plate 504 drives the sliding clamping angle 503 to move in the direction close to the fixed side plate 3, so that the thermal film 7 and the sliding clamping angle 503 no longer conflict. At the same time, the thermal film 7 and the flip clamping plate 601 approach each other, and the thermal film 7 conflicts with the two clip rotating plates 603, thereby causing the two clip rotating plates 603 to rotate outward and twist the torsion spring 604. Under the elastic torsion action of the torsion spring 604, the thermal film 7 conflicts with the clip rotating plate 603, thereby causing the thermal film 7 to be clamped inside the flip clamping plate 601.

[0041] At this time, with the further rotation of the rotating connecting column 409, the sliding connecting column 410 rotates toward the direction close to the rotating motor 408, thereby driving the sliding slot column 406 to move toward the direction close to the rotating motor 408. The sliding slot column 406 drives the rotating connecting block 404 to move toward the direction close to the rotating motor 408 through the connecting rotating column 405, thereby driving the half gear 402 to move toward the direction close to the rotating motor 408. The half gear 402 drives the flipping clamping plate 601 to move toward the direction close to the rotating motor 408 through the sliding rotating column 401, thereby driving the clamped thermal film 7 to move toward the other detection head 8. At the same time, the half gear 402 is re-engaged with the caliper plate 403, thereby driving the half gear 402 to rotate. The half gear 402 drives the flipping clamping plate 601 to rotate through the sliding rotating column 401, thereby realizing the flipping of the thermal film 7.

[0042] At the same time, with the movement of the sliding column 401, the sliding column 401 and the pushing rotating plate 508 are no longer engaged. At this time, under the elastic stretching action of the pushing spring 509, the reset sliding column 507 moves upward, thereby driving the connecting plate 506 and the end of the pushing rotating plate 508 close to the fixed plate 407 to move upward, and the connecting plate 506 drives the push sliding column 501 to move in the direction away from the sliding column 401, thereby making the push sliding column 501 return to its original position. At this time, the sliding clamping angle 503 moves in the direction away from the fixed side plate 3 under the push of the fixed side plate 3, thereby driving the connecting limit plate 504 to move in the direction away from the fixed side plate 3 and stretching the reset spring 505.

[0043] As the rotating connecting column 409 further rotates, the sliding groove column 406 moves toward the direction close to the other detection head 8, and then drives the thermal film 7 to move toward the direction close to the other detection head 8 through the flip clamp 601. At the same time, the sliding rotating column 401 abuts against the other pushing rotating plate 508, and then drives the other pushing sliding column 501 to move toward the direction close to the rotating motor 408. At this time, the other sliding clamping angle 503 no longer abuts against the fixed side plate 3, and then moves toward the direction close to the fixed side plate 3 under the elastic stretching action of the reset spring 505, so that the thermal film 7 can continue to move and abut against the other pushing clamping angle 502.

[0044] At this time, as the rotating connecting column 409 further rotates the sliding slot column 406 to move away from the other detection head 8, it no longer conflicts with the other pushing rotating plate 508. Under the elastic stretching action of the pushing spring 509, the other pushing sliding column 501 moves in the direction away from the rotating motor 408, so that the sliding clamping angle 503 conflicts with the side of the fixed side plate 3, and the sliding clamping angle 503 moves in the direction away from the fixed side plate 3 and stretches the reset spring 505. The sliding clamping angle 503 conflicts with the thermal film 7, and then drives the thermal film 7 to move in the direction away from the flip clamp 601, so that the flip clamp 601 no longer clamps the thermal film 7, and the clamp rotating plate 603 tilts toward the inside of the flip clamp 601 again under the elastic torsion action of the torsion spring 604.

[0045] At this time, the thermal film 7 moves away from the flip clamp 601 under the push of the sliding clamping angle 503, and completes the detection of another plane.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
