Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of appearance detection, in particular to a processing mold appearance detection equipment. BACKGROUND

[0002] Detecting the appearance of a processing mold is a key link to ensure the high-quality development of the manufacturing industry. Its necessity comes from many core needs. First, as a direct carrier for product forming, the surface defects (such as scratches, pits, and cracks) of the mold will be directly copied to the end product, resulting in poor appearance or even functional failure. Especially in high-precision fields such as automotive covers and semiconductor wafers, micron-level defects can cause batch rejection, causing huge economic losses. Second, traditional manual detection has the disadvantages of low efficiency, poor precision, and data loss, which cannot meet the requirements of modern production lines for second-level detection speed and micron-level precision. Machine vision and optical detection technology can realize accurate detection of full size and high repeatability through non-contact high-speed imaging and AI algorithm analysis, greatly improving detection efficiency and reliability. In addition, appearance detection data is an important basis for optimizing mold manufacturing processes. By analyzing defect types, locations, and fluctuation trends, it is possible to trace problems such as tool wear and thermal deformation in the processing process, providing data support for process parameter adjustment and equipment maintenance, and ultimately extending the service life of the mold and reducing production costs. Therefore, mold appearance detection is not only a key means of quality control, but also a key technical support for promoting intelligent manufacturing towards fine and data-oriented evolution.

[0003] When most of the mold appearance is uneven and the upper end is larger than the lower end in area, and the detection camera is located at the top of the detection box, it will bring many adverse effects. On the imaging, the upper end may block the lower end, making some features of the lower end unable to be captured by the camera. The large number of shadows produced by the uneven surface are easy to be misjudged as defects, and the different distances between the upper and lower ends and the camera will cause imaging perspective distortion. In terms of detection accuracy, feature recognition becomes difficult, size measurement is prone to error, and accurate judgment of mold quality is affected. Therefore, it does not meet the existing needs, and for this purpose, we propose a processing mold appearance detection equipment. SUMMARY

Please refer to Figures 1-7 A mold appearance detection device, comprising a conveying device 110 and a detection box 111 mounted on the shell of the conveying device 110, and a detection camera 112 for detecting the mold, a driving structure 120 for driving the detection camera 112 to rotate is mounted inside the detection box 111, the driving structure 120 comprises a sliding groove 121 opened in the inside of the detection box 111, a sliding block 122 matched with the sliding groove 121, and a driving rack 123 movably mounted on the upper side of the sliding block 122, a driving gear 124 engaged with the driving rack 123 is rotatably mounted in the inside of the detection box 111, a connecting shaft 180 is mounted on the front side of the driving gear 124, a first gear 190 is mounted on the end of the connecting shaft 180, a rotating gear 125 engaged with the first gear 190 is mounted in the inside of the detection box 111, and the detection camera 112 is arranged on the rotating gear 125.

[0029] The driving structure 120 further comprises a transverse groove 130 opened in the inner wall of the detection box 111, one side of the driving rack 123 slides in the inside of the transverse groove 130, and a supporting rod 131 is mounted between the driving rack 123 and the sliding block 122.

[0030] A movable groove 132 is opened in the inside of the detection box 111, the driving gear 124 and the rotating gear 125 are rotatably matched in the movable groove 132, a sliding block 133 is mounted on the side of the driving rack 123, and the sliding block 133 is slidably matched with the transverse groove 130.

[0031] The sliding groove 121 is arranged as an inclined groove, sealing strips 163 for light shielding are respectively mounted at the entrance and the exit of the detection box 111, and the rotating gear 125 is arranged as a half gear.

[0032] In actual implementation, the mold to be detected is placed on the belt of the conveying device 110, and as the conveying device 110 operates, the mold to be detected reaches the detection box 111, and at the same time, the protruding sliding block 122 is abutted in the process of the mold reaching the detection box 111, so that the sliding block 122 moves with the mold. In the process of the movement of the sliding block 122, the sliding block 122 drives the driving gear 124 to move by means of the supporting rod 131. In the process of the movement of the driving rack 123, the driving gear 124 is driven to rotate. In the process of the movement of the driving gear 124, the first gear 190 is driven to rotate by means of the cooperation of the connecting shaft 180. In the process of the rotation of the first gear 190, the rotating gear 125 is driven to rotate, so that the rotating gear 125 can scan the mold at the same time as the mold reaches the detection box 111.

As the belt stably operates, the mold to be detected is accurately conveyed into the detection box 111. In the process of the movement of the mold to the detection box 111, the protruding sliding block 122 on the mold is in contact with the preset abutment structure. Under the action of the abutment force, the sliding block 122 moves synchronously with the mold.

[0034] When the sliding block 122 moves, the driving gear 124 connected thereto is driven to move synchronously by means of the supporting rod 131. In the process of the movement of the driving gear 124, the driving gear 124 is in meshing with the fixed driving rack 123, so as to generate relative movement, and further drive the driving gear 124 to rotate. When the driving gear 124 rotates, the power is transmitted to the first gear 190 by means of the close cooperation of the connecting shaft 180, so as to drive the first gear 190 to rotate.

Even if the mold is in a continuous movement state during the detection process, the detection camera 112 can continuously and stably detect the mold by means of the accurate transmission of the rotating gear 125, so as to ensure that the detection work is uninterrupted and without omission.

[0036] Embodiment two, this embodiment is intended to facilitate the solution to the camera can follow the movement of the mold for lateral detection, but because the position of the detection camera is fixed, can not be vertical detection of the mold, resulting in detection there is obvious limitation. Transverse detection can only cover a certain level of the appearance or part of the characteristics of the mold, for the mold in the vertical direction of the size specification, structure details and possible defects can not be fully accessible information problem, this embodiment is made on the basis of embodiment one, for details, please refer to Figures 1-7 The driving structure 120 further comprises a connecting cylinder 140 installed on the side of the rotating gear 125, the surface of the connecting cylinder 140 is provided with a first track groove 141, the side of the rotating gear 125 is provided with a support frame 142, a driving rod 143 is movably inserted on the support frame 142, a cross rod 144 is installed at one end of the driving rod 143, a sliding column 145 is installed at the end of the cross rod 144, the sliding column 145 is slidingly fitted in the first track groove 141, a connecting plate 150 is installed at the other end of the driving rod 143, a driving motor 170 is installed in the rotating gear 125, the rotating shaft of the driving motor 170 is connected with the connecting cylinder 140.

[0037] In this embodiment: in the driving structure 120 for mold detection, when the driving motor 170 installed in the rotating gear 125 is started, the rotating shaft of the driving motor 170 is connected with the connecting cylinder 140, and the motor operation will drive the connecting cylinder 140 to start rotating.

[0038] The surface of the connecting cylinder 140 is carefully designed with the first track groove 141, and the unique track shape is the key to control the reciprocating movement of the driving rod.

[0039] With the rotation of the connecting cylinder 140, the first track groove 141 will exert a force on the sliding column 145. When the connecting cylinder 140 rotates to a certain position, the track of the first track groove 141 will push the sliding column 145 to move in a certain direction, thereby driving the cross rod 144 and the driving rod 143 to slide in one direction on the support frame 142; when the connecting cylinder 140 continues to rotate, the track of the first track groove 141 changes, which pulls the sliding column 145 to move in the opposite direction, so that the driving rod 143 slides in the opposite direction. Such a cycle, with the continuous rotation of the connecting cylinder 140, the sliding column 145 changes position in the first track groove 141, thereby driving the driving rod 143 to reciprocate on the support frame 142;

[0040] The other end of the driving rod 143 is installed with a connecting plate 150, which can be connected with the detection camera according to the overall detection logic.

[0041] The other end of the driving rod 143 is installed with a connecting plate 150, which can be connected with the detection camera according to the overall detection logic. Through the reciprocating movement of the driving rod 143, the detection camera can finally be driven to reciprocate in the corresponding direction, such as the vertical direction, to realize comprehensive detection of the mold in the vertical direction, make up for the deficiency that the detection camera cannot be vertically detected due to fixed position, and ensure the accuracy and integrity of the detection.

[0042] Embodiment three, this embodiment aims to promote the solution that although the detection camera can reach the vertical detection of the mold, due to problems, this embodiment is an improvement based on embodiment two, for details, please refer to Figures 1-7 , The front side of the connecting cylinder 140 is installed with a round plate 151, the surface of the round plate 151 is provided with a second track groove 152, the inside of the support frame 142 is rotatably installed with a rotating rod 153, the inside of the rotating rod 153 is inserted and installed with a movable rod 154, the movable rod 154 is movably connected with the connecting plate 150, the detection camera 112 is installed at the end of the movable rod 154, the end of the rotating rod 153 is installed with a connecting block 155, the side of the connecting block 155 is installed with a sliding column 160, and the sliding column 160 is in sliding fit with the second track groove 152.

[0043] The inside of the rotating rod 153 is hollow, and a plurality of convex ribs 161 are installed in the inside of the rotating rod 153. The plurality of convex ribs 161 are arranged in a ring shape on the surface of the rotating rod 153, the surface of the movable rod 154 is provided with a groove 162 matched with the convex ribs 161, and the convex ribs 161 are in sliding fit in the inside of the groove 162.

[0044] In this embodiment: in the driving structure, when the connecting barrel 140 rotates under the driving of the driving motor, not only will the detection camera be driven to move vertically reciprocatingly through the first track groove and other components as described above, but also a new movement will be caused due to the arrangement of the front circular plate 151 of the connecting barrel 140. The second track groove 152 provided on the surface of the circular plate 151 has a unique shape and direction, and the slide column 160 installed on the connecting block 155 at the end of the rotating rod 153 is in sliding fit with the second track groove 152. With the rotation of the circular plate 151 with the connecting barrel 140, the second track groove 152 will exert a force on the slide column 160, so that the slide column 160 moves along a specific track, and in turn drives the rotating rod 153 to rotate inside the support frame 142. When the rotating rod 153 rotates, the movable rod 154 inserted therein will change the angle, and since the movable rod 154 is movably connected with the connecting plate 150, and the detection camera 112 is installed at the end of the movable rod 154, the swinging of the detection camera 112 can be finally realized. The combination of the swinging and the vertical reciprocating movement enables the detection camera to detect the mold from more angles, greatly improves the comprehensiveness and accuracy of the detection, effectively avoids the missed detection problem caused by single detection angle, and provides a more reliable detection means for ensuring the mold quality.
