DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0030] like Figure 1-9A machine vision inspection device shown in the figure includes a wiring base 1, a conveyor belt 11 arranged on the wiring base 1, and a scanning camera 12 arranged above the conveyor belt 11, and also includes a width detection mechanism, which is arranged on the wiring base 1 and is used to detect the width of the product; a height detection mechanism, which is arranged on the wiring base 1 and is used to detect the height of the product; an adjustment mechanism, which is arranged on the height detection mechanism and supports the scanning camera 12, and is used to adjust the relative distance between the scanning camera 12 and the product; when the conveyor belt 11 transports the product, the width detection mechanism and the height detection mechanism synchronously detect the product, and drive the adjustment mechanism to synchronously adjust the scanning camera 12. Since there are packaging and transportation processes of different specifications and batches on the packaging production line, when a single batch of packaging is completed After the information is captured, the packaging and transportation of the next batch of specifications is often carried out. At this time, due to the change in the size of the package, the height position of the scanning camera 12 for scanning and capturing information is still maintained at the optimal scanning distance of the previous batch. , and then it is necessary to debug the height of the scanning camera 12 according to the specifications of the batch of products, so that it can maintain the optimal scanning distance for information capture operations. The conventional debugging method is performed manually. This manual debugging process has certain errors, and it is also necessary to suspend the transportation production line, which is not conducive to improving the operation efficiency. The device is provided with a width detection mechanism, a height detection mechanism and an adjustment mechanism around the conveyor belt 11, which cooperate with the operation of the conveyor belt 11 to implement synchronous operation, and perform width detection and height detection on the product specifications when the conveyor belt 11 transmits the product. At the same time, the adjustment mechanism is driven to adjust the scanning height of the scanning camera 12, and then when the product passes under the scanning camera 12, the scanning camera 12 has been maintained at the optimal scanning height, so that the information capture accuracy is maintained in the best state, and there is no need to suspend the production line, realizing a highly automated operation process and improving the production line efficiency.

[0031] In one embodiment, the height detection mechanism includes a height measuring component arranged above the conveyor belt 11 and a first driving component arranged on the wiring base 1 for supporting the height measuring component and driving the height measuring component to reciprocate up and down. The height measuring component includes a supporting rail frame 2 arranged above the side plates on both sides of the conveyor belt 11, a touch component that slides in a limited position in a limiting track 21 opened in the supporting rail frame 2 and is used to control the opening and closing of the first driving component, and a movable cross bar 22 rotatably connected to the touch component at both ends. The touch component includes a limiting slide plate 23 rotatably connected to the end of the movable cross bar 22, a limiting touch rod 24 arranged on the limiting slide plate 23, and a sliding sleeve on the limiting touch The friction block 25 on the rod 24 and limitedly slides in the limit track 21, the execution box 26 arranged on the friction block 25 and having a signal connection with the first driving component, the spring switch 27 arranged on the execution box 26 and facing the limit contact rod 24, and the return spring 28 sleeved on the limit contact rod 24 and one end of which is arranged on the limit slide plate 23 and the other end of which is arranged on the friction block 25, the first driving component includes a drive control box 3 arranged on the wiring base 1 and located on both sides of the conveyor belt 11, and a first threaded rod 31 rotatably mounted on the drive control box 3; the support rail frame 2 is provided with a first threaded sleeve plate 32 threadedly connected with the first threaded rod 31;A longitudinal limit slide bar 33 is also provided on the wiring base 1, and a limit sleeve 34 slidably connected to the longitudinal limit slide bar 33 is provided on the support rail frame 2. The height detection mechanism is provided to ensure that the scanning camera 12 is always in a position above the product packaging. It adjusts the scanning camera 12 to a minimum height position according to the height of the product, so that the width detection mechanism can adjust the scanning camera 12 for a second time based on this height to maintain it at an optimal scanning height. The operating principle of its height detection is to set a movable cross bar 22 above the conveyor belt 11. The movable cross bar 22 and the scanning camera 12 are at the same height position in the initial state. When the product is transported on the conveyor belt 11, the movable cross bar 22 will block the front of the product and be pushed forward by the movement of the product. When the movable cross bar 22 follows the product forward, the limit slide plates 23 at both ends thereof will slide synchronously in the limit track 21, and at the same time, the friction between the friction block 25 and the limit track 21 The force is large, while the friction between the limit slide plate 23 and the limit track 21 is small. Therefore, when the limit slide plate 23 slides forward, it will first drive the return spring 28 to compress, and then push the limit contact rod 24 to slide in the friction block 25, and then press on the spring switch 27, so that the execution box 26 transmits a signal to the drive control box 3, and then the drive control box 3 starts and drives the first threaded rod 31 to rotate. During the rotation process, the first threaded rod 31 drives the support rail frame 2 to move upward through the first threaded sleeve plate 32, and then drives the scanning camera 12 to move upward synchronously. At this time, the movable cross bar 22 is pushed by the product and moves upward synchronously until the movable cross bar 22 is above the product and separates from it, and then the limit slide plate 23 rebounds under the action of the return spring 28, so that the limit contact rod 24 is separated from the spring switch 27, and then the drive control box 3 stops moving. At this time, the height of the scanning camera 12 is automatically adjusted to a position above the product height. ;

[0032] In one embodiment, the width detection mechanism includes a width measuring component arranged on both sides of the conveyor belt 11 and used to clamp both sides of the product transported on the conveyor belt 11, and a second driving component arranged on the wiring base 1 for driving the width measuring component. The width measuring component includes a movable sleeve frame 4 arranged between the side plates on both sides of the conveyor belt 11 and the supporting rail frame 2, a guide rail frame 41 movably sleeved in the movable sleeve frame 4, guide wheels 42 rotatably arranged in the guide rail frame 41 and equidistantly arranged, and a movable bracket 43 arranged on the movable sleeve frame 4; a pressure sensor with signal communication with the second driving component is arranged between the guide rail frame 41 and the movable sleeve frame 4, and the second driving component includes a second driving component arranged on the wiring base 1. A driving motor 5, a bidirectional threaded screw 51 rotatably mounted on the first driving motor 5 and threadedly connected to the movable bracket 43, and a transverse limit slide 52 whose two ends are rotatably arranged on the wiring base 1 through a bearing frame and slidably connected to the movable bracket 43. The width detection mechanism is to ensure that the scanning camera 12 can always be located at the optimal grasping height position according to the width of different products, so as to facilitate the scanning camera 12 to scan the entire range information of the upper surface of the scanning camera 12. It needs to cooperate with the adjustment mechanism to adjust the height of the scanning camera 12, and it is used to detect the width of the product, and drive the adjustment mechanism through the action process of detecting the width, so as to achieve synchronous detection and adjustment. The main working principle is that when the product is transported on the conveyor belt 11, the first driving motor 5 drives the bidirectional threaded screw 51 to rotate, thereby making the two sets of movable brackets 43 relatively movable, so that the movable sleeve 4 drives the guide rail frame 41 to move to both sides of the product, so that the product gradually moves horizontally to the center position of the conveyor belt 11 under the action of thrust. At this time, the guide wheel 42 on the guide rail frame 41 will fit the surface of the product, and the guide rail frame 41 cannot move inward. Then, the guide rail frame 41 is subjected to the reaction force of the product to apply pressure to the pressure sensor arranged in the movable sleeve frame 4, and the pressure signal is fed back to the first driving motor 5, so that the first The driving motor 5 stops moving, and at this time the distance between the guide rails 41 is the width of the product. Since the width detection of the guide rails 41 is performed by clamping the product, in order not to affect the transportation of the product on the conveyor belt 11, the guide wheels 42 are used to reduce friction, so as to facilitate the normal movement of the product between the guide rails 41. Since the guide rails 41 remain different after moving to the two sides of the product, in order to facilitate subsequent product transportation, a guide plate 8 can also be set on the movable sleeve 4, and the guide plate 8 is used to guide the product to move to the position between the guide rails 41. The transportation trajectory of the product can also be corrected so that it is in the center position to be scanned by the scanning camera 12, further improving the accuracy of information capture.

[0033] In one embodiment, the adjusting mechanism includes a driven gear 6 which is arranged on the supporting rail frame 2 through the rotation of the bearing frame, a second threaded rod 61 which is arranged at the bottom end of the driven gear 6, a limiting slide rail 62 which is arranged on the supporting rail frame 2, a driving plate 64 which is limitedly slidable forward and backward along the traveling direction of the conveyor belt 11 on the limiting slide rail 62 and has a track groove 63 at the upper end, and a track rod 65 which is arranged on the movable bracket 43 and is slidably sleeved with the track groove 63; second threaded sleeve plates 66 which are threadedly connected with the driven gear 6 are arranged on both sides of the scanning camera 12, and a tooth surface which meshes with the second threaded rod 61 is arranged on the side of the driving plate 64 which is opposite to the driven gear 6. While the width detection mechanism detects the width of the product, the adjusting mechanism The scanning camera 12 is adjusted synchronously by the structure, so as to improve the debugging efficiency to the greatest extent. The specific principle is that when the first driving motor 5 drives the movable bracket 43 to move relatively, the track rod 65 on the movable bracket 43 will move synchronously toward the conveyor belt 11 side, so that the track rod 65 is abutted against the inner wall of the track groove 63 on the driving plate 64, and the driving plate 64 is pushed to move along the orthogonal direction of the movement trajectory of the track rod 65, and then the tooth surface on the driving plate 64 drives the second threaded rod 61 to rotate, so that the driven gear 6 rotates and controls the second threaded sleeve plate 66 to move upward on the driven gear 6, thereby driving the scanning camera 12 to move upward, thereby achieving the operation process of synchronously adjusting the height of the scanning camera 12.

[0034] In one embodiment, the support rail 2 is further provided with a second drive motor 7, on which a winding drum 71 is rotatably mounted, on which a connecting rope 72 is wound, and an outwardly extending slide 73 is provided on the side of the limiting slide 23 away from the movable cross bar 22. A limiting slot 74 for the outwardly extending slide 73 to limit the sliding of the outwardly extending slide 73 is provided on the support rail 2, and a pull ring 75 is provided on the outwardly extending slide 73. One end of the winding drum 71 away from the connecting rope 72 is buckled on the pull ring 75. Since multiple batches of products of different specifications need to be transported on the conveyor belt 11, when batches of products of different specifications enter the production line, it is necessary to perform a height adjustment action of the scanning camera 12, and before the next batch of products enters the production line, the detection mechanism and the adjustment mechanism need to be reset to realize the next detection and adjustment work, through the movable bracket 43 The structure driven by the drive control box 3 and having relevant transmission connection can be reset by the reverse operation of the first drive motor 5 and the drive control box 3. Since the touch control component and the movable cross bar 22 are driven by the product to move passively, they cannot be reset under normal conditions. Therefore, a connecting rope 72 is provided. When the movable cross bar 22 drives the limiting slide 23 to slide, the limiting slide 23 pulls the connecting rope 72 through the extending slide 73, so that the winding drum 71 rotates to release the connecting rope 72. When it is necessary to reset the movable cross bar 22 and the touch control component, the second drive motor 7 drives the winding drum 71 to rotate, thereby driving the connecting rope 72 to reel in, and then pulling the extending slide 73 back, so that the touch control component and the movable cross bar 22 are reset to their original state, so that the next batch of automatic debugging work can be carried out.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
