Description

Technical Field

[0001] This utility model belongs to the technical field of material handling mechanisms, and in particular relates to a rotary material handling mechanism. Background Technology

[0002] In automated equipment or production lines, after a product is placed on a carrier and photographed using an image sensor system (which can be used to detect defects in various products, identify and select objects, or measure dimensions), the product needs to be rotated, reset, and adjusted at an angle for more precise and efficient subsequent processing. Existing technologies include related rotary material handling structures. For example, Chinese Patent Publication No. CN209834996U discloses a novel rotary suction nozzle material handling mechanism where a first cylinder drives the suction nozzle seat to move downwards towards the product and adsorb the product through the suction nozzle, while a second cylinder drives the rotating arm to move horizontally along a chute. The rotating arm pin moves accordingly, and by moving along the guide groove of the swing arm, the swing arm swings horizontally around the nozzle, realizing the rotation of the nozzle along its vertical central axis, thereby rotating the product adsorbed by the nozzle to a certain angle. In this scheme, if there are more than or equal to eight products in each row or column of the material tray, the first cylinder drives eight nozzles to descend simultaneously. This picking mechanism can simultaneously pick up and adjust the angle of eight or fewer products. However, if there are fewer than eight products in each row or column of the material tray, when all eight nozzles descend simultaneously, some nozzles cannot contact the product or the side of the material tray, and the picking action will be interfered with. Therefore, this scheme has poor compatibility.

[0003] Therefore, it is necessary to provide a rotary material handling mechanism to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a rotary material handling mechanism that significantly improves versatility, precision, stability and functionality, and can effectively enhance the flexibility and efficiency of automated production lines.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a rotary material handling mechanism, comprising a mounting frame, a first driving member disposed on the mounting frame, a moving plate driven by the first driving member to move horizontally, and a plurality of adsorption modules spaced apart on the moving plate. The adsorption module comprises a fixed block fixed at one end on the moving plate, a movable shaft movably disposed in a guide hole at the other end of the fixed block, a swing block fixed at one end at the lower end of the movable shaft, a support shaft fixed at the other end of the swing block, and an adsorption assembly disposed at the lower end of the swing block. The upper end of the support shaft is rotatably disposed on the mounting frame. The adsorption assembly comprises an adsorption block for adsorbing products and a second driving member for driving the adsorption block to move up and down.

[0006] Furthermore, the adsorption block is mounted on the second driving member via a first connecting block, the first connecting block is fixed to the output shaft end of the second driving member, the adsorption block is fixed to the lower end of the first connecting block by fasteners, and the adsorption block is provided with adsorption holes.

[0007] Furthermore, one end of the fixing block with the guide hole extends out of the side of the moving plate and cantilevered out of the side of the mounting bracket.

[0008] Furthermore, the guide hole is an oblong hole and extends along the length direction of the fixing block.

[0009] Furthermore, the swing block is located below the mounting bracket and can swing left and right around the axis of the support shaft.

[0010] Furthermore, it also includes a limiting structure for left and right limiting of the movable plate.

[0011] Furthermore, the limiting structure includes a first limiting post and a second limiting post disposed at both ends of the mounting bracket, a first limiting block disposed at both ends of the movable plate that cooperates with the first limiting post, and a second limiting block that cooperates with the second limiting post. The first limiting block, the first limiting post, the second limiting post, and the second limiting block are arranged at intervals from left to right.

[0012] Furthermore, a second connecting block is connected to the end of the first driving member, and the other end of the second connecting block is fixed to the moving plate.

[0013] Furthermore, the mounting bracket is provided with a slide rail, and the movable plate is slidably mounted on the slide rail by a slider, with a plurality of the adsorption modules arranged at intervals along the length direction of the movable plate.

[0014] Furthermore, the upper end of the support shaft is rotatably mounted on the mounting frame via a first bearing, and the lower end is rotatably mounted on the support plate via a second bearing. The support plate is located below the mounting frame via several connecting rods, and the support plate is provided with several clearance notches for the adsorption block to rotate left and right.

[0015] Compared with the prior art, the beneficial effects of the rotary material handling mechanism of this utility model are as follows: (1) High versatility and flexibility: By setting up multiple independently liftable adsorption modules, the material picking mechanism can adapt to different specifications of trays. No matter how many products are in each row or column of the tray, the corresponding number of adsorption components can be selected for picking and placing, which significantly improves the adaptability of the material picking mechanism to various production scenarios. (2) Precise angle adjustment function: The first driving component drives the moving plate to move horizontally, which in turn drives the swing block to swing around the support axis, thereby realizing the angle rotation of the adsorption component and the product, or meeting the requirement of changing the direction of the long side and the short side of the product. It is suitable for precision operation occasions that require directional placement. (3) Stable structure and high motion accuracy: The sliding rail slider guide and the limiting structure (limiting column and limiting block) are used to accurately limit the moving plate, ensuring that the positions of multiple adsorption modules are consistent and reliable during movement and rotation, and avoiding the impact of cumulative error on the picking and placing accuracy; (4) Optimization of spatial layout: The cylinder is arranged horizontally to reduce the overall height; the support shaft is set on the mounting frame and support plate through bearings and reinforced by connecting rods to enhance the rigidity and stability of the adsorption module when rotating. At the same time, the support plate is provided with avoidance gaps to avoid interfering with the movement of the adsorption block. (5) High-efficiency collaborative operation: The material handling mechanism can be installed at the end of the robot or the handling mechanism to realize the integrated operation of material handling, rotation and unloading, improve the efficiency of automated production, and is especially suitable for industries such as electronics and semiconductors that have strict requirements for positioning and orientation; Therefore, this rotary material handling mechanism has significantly improved in terms of versatility, accuracy, stability and functionality, and can effectively enhance the flexibility and efficiency of automated production lines.

Detailed Implementation

[0017] Please refer to Figures 1-3 This embodiment is a rotary material handling mechanism 100, which includes a mounting frame 1, a first driving member 2 mounted on the mounting frame 1, a moving plate 3 driven by the first driving member 2 to move horizontally, and a plurality of adsorption modules 4 spaced apart on the moving plate 3. Each adsorption module 4 includes a fixing block 41 fixed at one end to the moving plate 3, a movable shaft 42 movably disposed in a guide hole 411 at the other end of the fixing block 41, a swing block 43 fixed at one end to the lower end of the movable shaft 42, a support shaft 44 fixed at the other end of the swing block 43, and an adsorption assembly 45 disposed at the lower end of the swing block 43. The upper end of the support shaft 44 is rotatably mounted on the mounting frame 1. The adsorption assembly 45 includes an adsorption block 451 for adsorbing products and a second driving member 452 for driving the adsorption block 451 to move up and down. In this solution, the moving plate 3 is provided with a plurality of adsorption modules 4. Regardless of the number of products placed in each row or column of the tray, each adsorption module 4 can be raised and lowered independently to pick up and place products, allowing for the pick-up and drop of products from the tray as needed, thus improving the versatility of the material handling mechanism. In this embodiment, four adsorption modules 4 are provided, which can simultaneously adsorb four or fewer products. If there are fewer than four products in each row or column of the tray, a relatively large number of adsorption components 45 can descend individually to pick up the products, thus improving the flexibility of the material handling mechanism. In other embodiments, the number of adsorption modules 4 can be set according to actual conditions, and the number of adsorption modules 4 is not limited here.

[0018] The adsorption block 451 is mounted on the second driving member 452 via a first connecting block 453. The first connecting block 453 is fixed to the output shaft end of the second driving member 452. The adsorption block 451 is fixed to the lower end of the first connecting block 453 via a fastener 454. The adsorption block 451 is provided with adsorption holes, through which gas is supplied to achieve adsorption of the product. In this embodiment, the fastener 454 can be selected from screws, bolts, and pins. In other embodiments, the fastener 454 can be set to other structures, which are not limited here.

[0019] Mounting bracket 1 is installed at the moving end of the handling mechanism or the robot arm. In this embodiment, the first driving component 2 is a cylinder. The cylinder is horizontally mounted on the mounting bracket 1, which can reduce the overall height of the rotating material handling mechanism 100. The output shaft 21 of the cylinder is connected to a second connecting block 22. The other end of the second connecting block 22 is fixed on the moving plate 3. The output shaft 21 of the cylinder extends or retracts horizontally, which can drive the moving plate 3 to move horizontally left and right.

[0020] One end of the fixing block 41 is fixed to the moving plate 3, and the other end extends out of the side of the moving plate 3 and cantilevered out of the side of the mounting frame 1. A guide hole 411 is provided on the end of the fixing block 41 that cantilevered out of the side of the mounting frame 1. That is, the end of the fixing block 41 with the guide hole 411 extends out of the side of the moving plate 3 and cantilevered out of the side of the mounting frame 1, so that the movable shaft 42 can move horizontally within the guide hole 411. In this embodiment, the guide hole 411 is an oblong hole and the oblong hole extends along the length direction of the fixing block 41, and the length direction of the fixing block 41 is perpendicular to the length direction of the moving plate 3.

[0021] The swing block 43 is positioned below the mounting bracket 1. When the moving plate 3 moves the fixed block 41 left and right, it can drive the movable shaft 42 to move horizontally within the guide hole 411. The swing block 43 is fixed to the lower end of the movable shaft 42 and can swing left and right around the axis of the support shaft 44. An adsorption component 45 is fixed below the swing block 43. When the moving plate 3 moves left and right, it causes the swing block 43 to swing left and right, thereby driving the adsorption component 45 to rotate left and right, thus achieving the rotation of the product angle. In this embodiment, the swing angle of the swing block 43 is 90°. Therefore, the adsorption component 45 can drive the product to rotate 90°, achieving the adjustment of the product angle. The 90° rotation can achieve the reversal of the long side and short side of the product. In other embodiments, the swing angle of the swing block 43 can be set according to the actual situation and is not limited here. For example, it can rotate at angles of 30°, 45°, 60°, etc.

[0022] Therefore, when the moving plate 3 moves left and right, several adsorption modules 4 can swing left and right. Generally, the size of the products is very small, and the position of several adsorption modules 4 needs to be very precise when picking up materials. Therefore, it is necessary to limit the position of several adsorption modules 4. Since the adsorption modules 4 are fixed on the moving plate 3, limiting the moving plate 3 can achieve the limitation of several adsorption modules 4. A rotating material picking mechanism 100 also includes a limiting structure 5 for limiting the left and right position of the moving plate 3. The limiting structure 5 includes a first limiting post 51 and a second limiting post 52 set at both ends of the mounting frame 1, a first limiting block 53 correspondingly set at both ends of the moving plate 3 to cooperate with the first limiting post 51, and a second limiting block 54 to cooperate with the second limiting post 52. The first limiting block 53, the first limiting post 51, the second limiting post 52, and the second limiting block 54 are arranged at intervals from left to right. When the first driving member 2 drives the moving plate 3 to move to the left, the second limiting block 54 abuts against the second limiting post 52 to limit the final position on the left. When the first driving member 2 drives the moving plate 3 to move to the right, the first limiting block 53 abuts against the first limiting post 51 to limit the final position on the right.

[0023] The mounting bracket 1 is equipped with a slide rail 11, and the movable plate 3 is slidably mounted on the slide rail 11 via a slider 12. Several adsorption modules 4 are arranged at intervals along the length of the movable plate 3.

[0024] The upper end of the support shaft 44 is rotatably mounted on the mounting frame 1 via the first bearing 6, and the lower end is rotatably mounted on the support plate 8 via the second bearing 7. The support plate 8 is positioned below the mounting frame 1 via several connecting rods 9, and has several clearance notches 81 on it to allow the adsorption block 451 to rotate left and right. The support shaft 44, connecting rods 9, and support plate 8 are all designed to ensure the stability of the adsorption assembly 45 during rotation.

[0025] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
