Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conveying technology, and in particular relates to a visual alignment and bonding mechanism. Background Technology
[0002] Traditional bonding mechanisms use mechanical devices with two opposite edges to limit the workpiece's position. However, this mechanical positioning requires manual intervention, which is not only inefficient but also prone to errors.
[0003] In related technologies, a single vision module is used for positioning. However, this method relies on only one camera. After importing an image into the computer software, the vision module first captures the initial position, then, based on the image's pattern, captures the diagonal position of the initial position to confirm the center position, and finally returns to the starting point. However, this single vision module is inefficient and takes a long time to locate.
[0004] Therefore, how to solve the problem of long positioning time for a single vision module is a technical problem that urgently needs to be solved in this field.

[0054] Research revealed the following drawbacks of existing technologies: While related technologies employ a single vision module for positioning, this method relies on only one camera. After importing the cropping graphic into the computer cropping software, the vision module first captures the initial position, then, based on the graphic's pattern, captures the diagonal positions of that initial position to confirm the center position. Once the vision module returns to the starting point, the cropping device begins cropping. However, this single vision module is inefficient and requires a long positioning time.
[0055] Therefore, how to solve the problem of long positioning time for a single vision module is a technical problem that urgently needs to be solved in this field.
[0056] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

A conveying mechanism 2 is disposed on the frame 1, the conveying mechanism 2 being adapted to drive the workpiece to move horizontally; after the workpiece is placed on the conveying mechanism 2, the conveying mechanism 2 is adapted to drive the workpiece to move horizontally between two vision modules 3, the two vision modules 3 being pre-adjusted according to the specifications and dimensions of the workpiece. The two vision modules 3 are diagonally disposed on the upper end of the frame 1; the conveying mechanism 2 includes an adjustment platform 20, the adjustment platform 20 being adapted to move relative to the frame 1;
[0060] The control module is electrically connected to the conveying mechanism 2 and the two vision modules 3, respectively. It is configured to, after the conveying mechanism 2 drives the workpiece to move below the vision modules 3, control the two vision modules 3 to position the workpiece from two opposite diagonal directions, and activate the adjustment platform 20 to adjust the position of the workpiece relative to the vision modules 3. Specifically, after the conveying mechanism 2 drives the workpiece to move below the vision modules 3, the two vision modules 3 position the workpiece from two opposite diagonal directions. After positioning, the adjustment platform 20 is adapted to adjust the position of the workpiece relative to the vision modules 3. Through the cooperation of the vision modules 3 and the conveying mechanism 2, after the workpiece moves below the vision modules 3, the vision modules 3 take pictures of the two opposite diagonals of the workpiece for positioning. The adjustment platform 20 adjusts the position of the workpiece relative to the vision modules 3 according to the signals transmitted by the vision modules 3, quickly and efficiently completing the visual alignment and bonding work of sheet products. The relative position of the two vision sensors 34 can be adjusted according to the product specifications and dimensions, solving the problems of traditional single-product and complex debugging, and improving work efficiency.
[0061] Reference Appendix Figure 2The conveying mechanism 2 includes: a lead screw module 21, which is disposed on the upper end of the frame 1; the lead screw module 21 extends along the moving direction of the workpiece, and a servo motor is provided inside the lead screw module 21. The servo motor is electrically connected to the control module, and the workpiece movement position can be accurately positioned by the servo motor. The lead screw module 21 is adapted to drive the adjustment platform 20 to move horizontally. When the workpiece is placed on the lower suction plate 23, the lower suction plate 23 uses negative pressure to adsorb and limit the workpiece, and the lead screw module 21 drives the adjustment platform 20 to move horizontally synchronously with the lower suction plate 23. The adjustment platform 20 is disposed on the slider of the lead screw module 21; two lifting cylinders 22 are respectively vertically disposed on both sides of the adjustment platform 20; the lower suction plate 23 is disposed at the movable end of the lifting cylinder 22 and is parallel to the adjustment platform 20. The control module is electrically connected to the lead screw module 21, the adjustment platform 20, and the two lifting cylinders 22, and is also configured to activate the adjustment platform 20 to adjust the position of the workpiece relative to the vision module 3 after the workpiece is positioned on the lower suction plate 23. The lower suction plate 23 has a matrix of negative pressure holes connected to a negative pressure pump, which is electrically connected to the control module. When the workpiece is placed on the lower suction plate 23, the negative pressure pump is adapted to perform negative pressure suction to limit the workpiece. The lifting cylinders 22 are adapted to drive the lower suction plate 23 to move vertically up and down. The adjustment platform 20 is a UVW alignment platform and is electrically connected to the two vision modules 3. The adjustment platform 20 can adjust the position of the workpiece on the lower suction plate 23 according to the signals transmitted by the two vision modules 3. Here, "position" refers to the relative position of the workpiece located at the upper end of the lower suction plate 23 to the two vision modules 3. The UVW alignment platform, also known as the XXY / XYR alignment platform, is a three-axis parallel motion mechanism. It achieves linear motion along the X and Y axes and rotational motion along the θz axis through the parallel movement of three linear translation axes. The UVW alignment platform is a device capable of rotational motion around any point on a plane and translational motion in any direction. The UVW platform and vision module 3 are electrically connected, enabling rapid and high-precision alignment correction with high repeatability.

The X-axis module 33 is adapted to drive the vision sensor 34 to slide back and forth along the X-axis direction in the horizontal direction. The cooperation between the Y-axis module 32 and the X-axis module 33 is adapted to adjust the position of the vision sensor 34 so that the distance between the two vision sensors 34 is equal to the distance between the two opposite corners of the workpiece.
[0063] Furthermore, a first driver 35 is provided at one end of the Y-axis module 32, which is adapted to drive the X-axis module 33 to move horizontally; a second driver 36 is provided at one end of the X-axis module 33, which is adapted to drive the vision sensor 34 to move horizontally.
