Detailed implementation manners

[0025] Embodiment 1

[0026] Please refer to Figures 1 to 3 , which is a schematic diagram of a coaxial multi-stroke adjustable mechanism and a material-transfer device provided by the present utility model. The coaxial multi-stroke adjustable mechanism includes: a support frame 10, a mounting frame 20 arranged on the support frame 10, a co-directional drive assembly 30 arranged on the mounting frame 20, a guiding assembly 50, and a stroke-limiting assembly 60 connected to the co-directional drive assembly 30. It can be imagined that the coaxial multi-stroke adjustable mechanism further includes other functional components and specific structures, such as an electrical connection component, an AOI control component, a mounting structure, etc., which are all well-known technologies to those skilled in the art, so they will not be elaborated in detail herein one by one.

[0027] The support frame 10 is in a rectangular frame structure and is vertically installed on the ground or an equipment platform, playing the role of component installation and overall counterweight stability.

[0028] The mounting frame 20 is slidably connected to the upper end of the support frame 10 longitudinally along the support frame 10. Specifically, longitudinal tracks are provided at the upper end of the mounting frame 20, and fixed guiding blocks corresponding to the longitudinal tracks and a longitudinal driver capable of driving the entire mounting frame 20 to slide are provided on the support frame 10. In this embodiment, the longitudinal driver is a cylinder. The longitudinal direction of the support frame 10 is the width direction of the mounting frame 20, providing a longitudinal movement direction for subsequent materials.

[0029] The co-directional drive assembly 30 includes a fixed-stroke driver 31 arranged at the upper end of the mounting frame 20, and the fixed-stroke driver 31 is a cylinder. In this embodiment, the single driving stroke of the fixed-stroke driver 31 is a fixed distance and is a short stroke. An adjustable-stroke driver 32 and a material-taking structure 40 are sequentially connected to the output end of the fixed-stroke driver 31. During the driving process, it is set that the fixed-stroke driver 31 and the adjustable-stroke driver 32 cannot be driven simultaneously to avoid driving distance deviation. The fixed-stroke driver 31 can drive the adjustable-stroke driver 32 and the material-taking structure 40 to move synchronously, and the fixed distance is usually applicable to the top-in place of material blanking and loading onto a tray.

[0030] The adjustable stroke driver 32 is a cylinder. In this embodiment, the single - drive stroke of the adjustable stroke driver 32 is variable. Specifically, it can be adjusted according to the material - taking structure 40 fitting on the upper end of the material. And after the material - taking structure 40 abuts against the material and is stressed, the adjustable stroke driver 32 brakes. It has strong versatility and is suitable for feeding materials at different heights of the material stack. Moreover, it cooperates with the AOI component to identify the grasping of the material. A connecting housing 33 is provided on the outer wall of the adjustable stroke driver 32. The cross - section of the connecting housing 33 is in a U - shaped structure. Specifically, the connecting housing 33 is arranged at both ends and the side wall of the adjustable stroke driver 32. The output end of the fixed - stroke driver 31 is arranged on the connecting housing 33. The connecting housing 33 realizes the flatness of the outer contour of the adjustable stroke driver 32, which is convenient for component connection and the axial push of the fixed - stroke driver 31. The fixed - stroke driver 31 and the adjustable stroke driver 32 are suitable for different material loading and unloading environments to meet different conveying distance requirements.

[0031] A material - taking structure 40 is provided at the output end of the adjustable stroke driver 32. The output end of the adjustable stroke driver 32 can pass through the mounting frame 20, and the material - taking structure 40 is located outside the mounting frame 20 to avoid displacement interference between the material - taking structure 40 and the mounting frame 20. Specifically, the material - taking structure 40 includes a lifting plate 41 respectively connected to the output end of the adjustable stroke driver 32 and the guiding assembly 50. The lifting plate 41 serves as a connecting body to realize the combined installation of various components. The output end of the adjustable stroke driver 32 is connected to the lifting plate through a floating joint 34. Through the floating joint 34, the hole - position installation deviation can be eliminated, and the connection reliability between the two can be increased. At least one set of material - taking devices 42 is provided on the lifting plate 41 away from the adjustable stroke driver 32. The material - taking devices 42 are used to grasp and hold the material. The material - taking devices 42 include any one of pneumatic suction cups or pneumatic grippers. In this embodiment, the material - taking devices 42 adopt the form of pneumatic suction cups. The lateral displacer 43 is used to drive the material - taking devices 42 to displace laterally along the lifting plate 41. The lateral direction of the lifting plate 41 is the length direction of the support frame 10, which increases the material - taking range of the material - taking structure 40. Optimally, there are two sets of material - taking devices 42 and they are correspondingly arranged at the bottom of both sides of the lifting plate 41. The symmetrically arranged material - taking devices 42 make the weights on both sides of the lifting plate balanced and the forces evenly distributed after grasping the material. The lateral displacer 43 is arranged in the middle of the lifting plate 41, and the lateral displacer 43 is in a two - way drive mode, respectively driving the two sets of material - taking devices 42 to displace laterally.

[0032] The guiding assembly 50 includes at least two linear bearings 51 spaced apart on the mounting bracket 20. In this embodiment, there are four linear bearings 51, and the linear bearings 51 are linear flange bearings, which increases the mounting stability and guiding accuracy of the linear bearings 51 on the mounting bracket 20. A guiding column 52 is axially inserted into each linear bearing 51 correspondingly. One end of the guiding column 52 is connected to the lifting plate 41 and moves axially following the lifting plate 41. It can be conceived that the fixed-stroke driver 31 and the adjustable-stroke driver 32 are coaxially connected, and share a guiding assembly 50, which reduces the installation occupied space and improves the guiding accuracy.

[0033] The ends of the two guiding columns 52 away from the material taking structure 40 are connected by a connecting rod 53, which makes the structure more compact and prevents the guiding columns 52 from disengaging from the linear bearings 51. An axially arranged buffer 54 is inserted into the connecting rod 53. By setting the buffer 54, the driving speed of the material taking structure 40 can be increased, and the collision degree can be reduced through the buffer 54, playing a role in protecting the structure.

[0034] The stroke limiting assembly 60 includes a limiting guide rail 61 axially arranged on the outside of the adjustable-stroke driver 32 along the axis of the adjustable-stroke driver 32. In this embodiment, the limiting guide rails 61 are all arranged on the connecting housing 33. A sliding groove block 62 for the limiting guide rail 61 to slide and connect is provided on the mounting bracket 20. Through the sliding groove block 62 and the limiting guide rail 61, a fixed fulcrum of the adjustable-stroke driver 32 is formed on the mounting bracket 20, and a moving guide is provided for the adjustable-stroke driver 32.
