Description

Technical Field

[0001] The present invention relates to the technical field of LED patch detection, and specifically provides an appearance detection device and a usage method for an LED patch bracket. Background Art

[0002] The LED patch lamp is made of an FPC circuit board, an LED lamp, and a high-quality silica gel sleeve; it has waterproof performance, is safe and convenient to use with low-voltage DC power supply, has various luminous colors, and is colorful. The LED patch bracket is used to fix the LED patch. During the production process of the LED patch bracket, its appearance usually needs to be detected to check whether the LED patch bracket is a qualified product.

[0003] When the existing appearance detection device for the LED patch bracket is in use, it needs to be placed under the detection head for detection. However, it can only detect the front side of the LED patch bracket, which is inconvenient for comprehensively detecting the LED patch bracket, and the detection accuracy is not good. At the same time, after the detection is completed, the staff still needs to take it out, which reduces the detection efficiency and increases the working intensity of the operator. In addition, during the detection, the next LED patch bracket cannot be pre-treated and fixed in advance, resulting in low detection efficiency.

[0015] The present invention also provides an appearance detection method for an LED patch bracket, which is detected by using the aforementioned device, and includes the following steps:

[0016] S1: When in use, place the LED patch bracket body to be detected above one of the fixed plates, and then the operation of the hydraulic cylinder B will drive the clamping plates to move relatively to clamp and fix it. After the fixation is completed, the servo motor can be operated. When the servo motor works, it will drive one of the synchronous pulleys to rotate, and then drive the other synchronous pulleys to rotate synchronously under the transmission of the synchronous belt. At this time, the synchronous belt will also rotate accordingly. When the synchronous belt rotates, it will drive the fixed clamping blocks on both sides to move relatively. When the fixed clamping blocks move, they will drive the movable plate A and the movable plate to move relatively, and then drive the fixed plate to move relatively. When the movable plate A moves, it will drive the LED patch bracket body to move closer to the detection head. When the infrared sensor detects the LED patch bracket body, the detection head can be operated to detect it. When moving, the transmission gear will be engaged with the fixed rack plate and deflected, so as to turn over the LED patch bracket body and drive the scroll spring to wind up, which is beneficial to the restoration of the transmission gear when it is away from the fixed rack plate. Similarly, it will also control the operation of the detection head on the other side to detect it under the detection of the infrared sensor;

[0017] S2: When the movable plate moves, it will drive the movable plate B to move together through the sliding rod. When the movable plate B moves, it will drive the sliding shaft to move in the inner cavity of the special-shaped groove through the special-shaped sliding plate, and under its guidance, it will drive the movable plate B to move downward. At the same time, it will make the sliding rod slide on the movable plate, which is conducive to the relative movement exchange between the movable plate A and the movable plate B. When the movable plate A moves to the inside, it will also make the movable plate B move to the outside. Then, the staff can pre-treat and fix the LED patch bracket body above the movable plate B. And with the operation of the servo motor, the movable plate A and the movable plate B will exchange back and forth, which is conducive to the development of the detection work;

[0018] S3: When the movable plate A moves, it will drive the sliding block to move through the straight rod. When the sliding block moves, it will drive the transmission rack plate B to move. At the same time, it will also drive the transmission rack plate A to move through the cross bar. When the transmission rack plate A moves, it will drive the large gear to rotate. The rotation of the large gear will drive the small gear to rotate. The rotation of the small gear will drive the upper moving rack plate to move. The movement of the upper moving rack plate will drive the sliding plate to slide through the L-shaped rod, so as to drive the material receiving plate to move outwards and compress the return spring. The staff can release the fixation of the LED patch bracket body by operating the hydraulic cylinder B inside, which is convenient for the staff to take it;

[0019] S4: When the transmission rack plate A moves away from the large gear, the material receiving plate can be restored under the action of the resilience of the return spring. As the movable plate A moves, the transmission rack plate B will engage with the movable gear and drive it to rotate. When the movable gear rotates, it will drive the upper moving rack plate to move inwards, and drive the material receiving plate to move inwards through the L-shaped rod, so that the return spring extends. This is conducive for the staff to release the fixation of the LED patch bracket body after the detection is completed, so that it falls on the material receiving plate. When it moves away, the material receiving plate can be restored under the action of the resilience of the return spring, which is also convenient for the staff to take it;

[0020] S5: Through the continuous operation of the servo motor, it will drive the movable plate A and the movable plate B to exchange back and forth, and the appearance of a large number of LED patch bracket bodies can be detected;

[0021] S6: Finally, the staff can separately take and collect the qualified and unqualified ones.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Through the mutual cooperation between these components such as the sliding plate, the moving rod, the return spring, the material receiving plate, the L-shaped rod, the moving rack plate, the movable gear, the small gear, the large gear, the transmission rack plate A and the transmission rack plate B, the LED patch brackets on the movable plate A and the movable plate B can be fed and slid to the outside of the n-shaped plate, which is convenient for the staff to take and improves the detection efficiency.

[0024] 2. Through the mutual cooperation among components such as the fixing plate, L-shaped plate, turntable, iron suction block A, iron suction block B, hydraulic cylinder B, clamping plate, rotating rod, scroll spring, fixed rod, and transmission gear, the fixation of the LED patch bracket can be achieved. At the same time, in combination with the connecting plate and the fixed rack plate, the turning-over detection of the LED patch bracket can be realized, without the need for staff operation, and the use effect is good.

[0025] 3. Through the mutual cooperation among components such as the side plate, synchronous pulley, synchronous belt, servo motor, fixed clamp block, moving plate A, movable plate, moving plate B, special-shaped sliding plate, guide plate, special-shaped groove, and sliding shaft, the exchange of moving plate A and moving plate B can be realized, which is beneficial to pre-treating the LED patch bracket on moving plate B when detecting the LED patch bracket above moving plate A, achieving its clamping and fixation, and making the detection efficiency better.

[0049] The present invention also provides a method for detecting the appearance of an LED chip bracket, which uses the aforementioned device for detection and includes the following steps:

[0050] S1: During use, place the LED chip bracket body to be detected above one side fixed plate 81, and then the operation of the hydraulic cylinder B84 will drive the clamping plate 85 to move relatively to clamp and fix it. After the fixation is completed, the servo motor 94 can be operated. When the servo motor 94 works, it will drive one of the synchronous wheels 92 to rotate, and then drive other synchronous wheels 92 to rotate synchronously under the transmission of the synchronous belt 93. At this time, the synchronous belt 93 will also rotate accordingly. When the synchronous belt 93 rotates, it will drive the fixed clamping blocks 95 on both sides to move relatively. When the fixed clamping blocks 95 move, they will drive the moving plate A96 and the movable plate 97 to move relatively, and then drive the fixed plate 81 to move relatively. When the moving plate A96 moves, it will drive the LED chip bracket body to move closer to the detection head 5. When the infrared sensor detects the LED chip bracket body, the detection head 5 can be operated to detect it. When moving, the transmission gear 87 will engage and deflect with the fixed rack plate 32, so as to turn over the LED chip bracket body and drive the volute spring 861 to wind up, which is beneficial for the transmission gear 87 to recover when it is away from the fixed rack plate 32. Similarly, under the detection of the infrared sensor, the detection head 5 on the other side will be controlled to operate to detect it;

[0051] S2: When the movable plate 97 moves, it will drive the moving plate B98 to move together through the sliding rod. When the moving plate B98 moves, it will drive the slide shaft 993 to move in the inner cavity of the special-shaped groove 992 through the special-shaped slide plate 99, and under its guidance, it will drive the moving plate B98 to move downward. At the same time, the sliding rod will slide on the movable plate 97, which is beneficial for the relative movement exchange between the moving plate A96 and the moving plate B98. When the moving plate A96 moves to the inside, the moving plate B98 will also move to the outside. Then the staff can pre-treat and fix the LED chip bracket body above the moving plate B98. And with the operation of the servo motor 94, the moving plate A96 and the moving plate B98 will exchange back and forth, which is beneficial for the development of the detection work;

[0052] S3: When the moving plate A96 moves, it will drive the slider to move through the straight rod. When the slider moves, it will drive the transmission rack plate B79 to move. At the same time, it will also drive the transmission rack plate A78 to move through the cross bar. When the transmission rack plate A78 moves, it will drive the large gear 77 to rotate. The rotation of the large gear 77 will drive the small gear 76 to rotate. The rotation of the small gear 76 will drive the upper moving rack plate 74 to move. The movement of the upper moving rack plate 74 will drive the sliding plate 71 to slide through the L-shaped rod 73, so as to drive the receiving plate 72 to move outwards and compress the return spring 712. The staff can release the fixation of the LED patch bracket body by operating the inner hydraulic cylinder B84, which is convenient for the staff to take it.

[0053] S4: When the transmission rack plate A78 moves away from the large gear 77, the receiving plate 72 can be restored under the action of the return spring force of the return spring 712. As the moving plate A96 moves, the transmission rack plate B79 will engage with the movable gear 75 and drive it to rotate. When the movable gear 75 rotates, it will drive the upper moving rack plate 74 to move inwards, and drive the receiving plate 72 to move inwards through the L-shaped rod 73, extending the return spring 712. This is conducive to the staff releasing the fixation of the LED patch bracket body after inspection, so that it falls on the receiving plate 72. When moving away, the receiving plate 72 can be restored under the action of the return spring force of the return spring 712, which is also convenient for the staff to take.

[0054] S5: Through the continuous operation of the servo motor 94, the moving plate A96 and the moving plate B98 will be exchanged back and forth, and the appearance of a large number of LED patch bracket bodies can be detected.

[0055] S6: Finally, the staff can separately take and collect the qualified and unqualified ones.

[0056] Working principle: When in use, place the LED patch bracket body to be detected above the fixed plate 81 on one side. Then, the operation of the hydraulic cylinder B84 will drive the clamping plate 85 to move relatively to clamp and fix it. After the fixation is completed, the servo motor 94 can be operated. When the servo motor 94 works, it will drive one of the synchronous wheels 92 to rotate. Then, under the drive of the synchronous belt 93, other synchronous wheels 92 will rotate synchronously. At this time, the synchronous belt 93 will also rotate accordingly. When the synchronous belt 93 rotates, it will drive the fixed clamping blocks 95 on both sides to move relatively. When the fixed clamping blocks 95 move, they will drive the moving plate A96 and the movable plate 97 to move relatively, thereby driving the fixed plate 81 to move relatively. When the moving plate A96 moves, it will drive the LED patch bracket body to move closer to the detection head 5. When the infrared sensor detects the LED patch bracket body, the detection head 5 can be operated to detect it. As it moves, the transmission gear 87 will mesh with the fixed rack plate 32 and deflect, thereby turning over the LED patch bracket body and driving the scroll spring 861 to wind up, which is beneficial for the transmission gear 87 to recover when it is away from the fixed rack plate 32. Similarly, under the detection of the infrared sensor, the detection head 5 on the other side will be controlled to operate to detect it. When the movable plate 97 moves, it will drive the moving plate B98 to move together through the sliding rod. When the moving plate B98 moves, it will drive the sliding shaft 993 to move in the inner cavity of the special-shaped groove 992 through the special-shaped slide plate 99, and under its guidance, it will drive the moving plate B98 to move downward. At the same time, the sliding rod will slide on the movable plate 97, which is beneficial for the relative movement exchange between the moving plate A96 and the moving plate B98. When the moving plate A96 moves to the inner side, the moving plate B98 will also move to the outer side. Then, the staff can pre-treat and fix the LED patch bracket body above the moving plate B98. And with the operation of the servo motor 94, the moving plate A96 and the moving plate B98 will exchange back and forth, which is beneficial for the development of the detection work. When the moving plate A96 moves, it will drive the sliding block to move through the straight rod. When the sliding block moves, it will drive the transmission rack plate B79 to move through the cross bar. At the same time, it will also drive the transmission rack plate A78 to move through the cross bar. When the transmission rack plate A78 moves, it will drive the large gear 77 to rotate. The rotation of the large gear 77 will drive the small gear 76 to rotate. The rotation of the small gear 76 will drive the upper moving rack plate 74 to move. The movement of the upper moving rack plate 74 will drive the sliding plate 71 to slide through the L-shaped rod 73, thereby driving the material receiving plate 72 to move outwards and compressing the return spring 712. The staff can release the fixation of the LED patch bracket body by operating the hydraulic cylinder B84 on the inner side, which is convenient for the staff to take. When the transmission rack plate A78 is away from the large gear 77, the material receiving plate 72 can be restored under the action of the resilience of the return spring 712. As the moving plate A96 moves, the transmission rack plate B79 will mesh with the movable gear 75 and drive it to rotate. When the movable gear 75 rotates, it will drive the upper moving rack plate 74 to move inwards, and drive the material receiving plate 72 to move inwards through the L-shaped rod 73.The reset spring 712 is extended, which facilitates the staff to release the fixation of the LED patch bracket body after the detection is completed, so that it falls on the material receiving plate 72. When moving away, the material receiving plate 72 can be restored under the action of the resilience of the reset spring 712, which is also convenient for the staff to take. Through the continuous operation of the servo motor 94, the moving plate A 96 and the moving plate B 98 can be driven to exchange back and forth, and the appearance of a large number of LED patch bracket bodies can be detected. Finally, the staff can separately take and collect the qualified and unqualified ones after detection.

8. A method for detecting the appearance of an LED patch bracket, characterized in that: Using the LED patch bracket appearance detection device according to claim 7, the detection method comprises the following steps: S1: When in use, the LED patch bracket body to be tested is placed above the fixed plate (81) on one side, and then the operation of the hydraulic cylinder B (84) drives the clamping plate (85) to move relatively to achieve clamping and fixing. After the fixing is completed, the servo motor (94) can be operated. When the servo motor (94) is working, it will drive one of the synchronous wheels (92) to rotate, and then drive the other synchronous wheels (92) to rotate synchronously under the transmission of the synchronous belt (93). At this time, the synchronous belt (93) will also rotate accordingly. When the synchronous belt (93) rotates, it will drive the fixed clamps (95) on both sides to move relatively. When the fixed clamps (95) move, they will drive the movable plate A (96). The movable plate (97) moves relative to the fixed plate (81), and the movable plate (96) moves to drive the LED patch bracket body to move closer to the detection head (5). When the infrared sensor detects the LED patch bracket body, the detection head (5) can be operated to detect it. As the movement occurs, the transmission gear (87) and the fixed rack plate (32) are meshed and deflected, so that the LED patch bracket body can be turned over, and the spiral spring (861) can be rolled up, which is conducive to the transmission gear (87) to be restored when it is away from the fixed rack plate (32). Similarly, under the detection of the infrared sensor, the detection head (5) on the other side can be controlled to operate to detect it. S2: When the movable plate (97) moves, the movable plate B (98) is driven to move through the sliding rod. When the movable plate B (98) moves, the sliding shaft (993) is driven to move in the inner cavity of the special-shaped groove (992) through the special-shaped slide plate (99). Under the guidance of the special-shaped slide plate (99), the movable plate B (98) is driven to move downward. At the same time, the sliding rod is caused to slide on the movable plate (97), which is conducive to the relative movement exchange between the movable plate A (96) and the movable plate B (98). When the movable plate A (96) moves to the inside, the movable plate B (98) is also moved to the outside. Then, the staff can pre-process and fix the LED patch bracket body above the movable plate B (98). With the operation of the servo motor (94), the movable plate A (96) and the movable plate B (98) are exchanged back and forth, which is conducive to the development of the detection work. S3: When the movable plate A (96) moves, it drives the sliding block to move through the straight rod. When the sliding block moves, it drives the transmission rack plate B (79) to move. At the same time, it drives the transmission rack plate A (78) to move through the cross rod. When the transmission rack plate A (78) moves, it drives the large gear (77) to rotate. The rotation of the large gear (77) drives the small gear (76) to rotate. The rotation of the small gear (76) drives the upper movable rack plate (74) to move. The movement of the upper movable rack plate (74) drives the sliding plate (71) to slide through the L-shaped rod (73), thereby driving the receiving plate (72) to move outward and compressing the reset spring (712). The staff can release the fixation of the LED patch bracket body by operating the inner hydraulic cylinder B (84), so that the staff can take it conveniently. S4: When the transmission rack plate A (78) is away from the large gear (77), the receiving plate (72) can be restored under the action of the rebound force of the return spring (712). As the movable plate A (96) moves, the transmission rack plate B (79) will mesh with the movable gear (75) and drive it to rotate. When the movable gear (75) rotates, it will drive the upper movable rack plate (74) to move inward, and drive the receiving plate (72) to move inward through the L-shaped rod (73), so that the return spring (712) extends, which is convenient for the staff to release the fixation of the LED patch bracket body after the inspection is completed, so that it falls on the receiving plate (72). When it is away, the receiving plate (72) can be restored under the action of the rebound force of the return spring (712), which is also convenient for the staff to take it; S5: The continuous operation of the servo motor (94) drives the movable plate A (96) and the movable plate B (98) to be exchanged back and forth, so that a large number of LED patch bracket bodies can be inspected for appearance; S6: Finally, the staff will collect the qualified and unqualified samples separately.
