Description

Technical Field

[0001] This invention relates to the technical field of machining material feeding, specifically to a multi-station automatic material handling device. Background Technology

[0002] Existing multi-station gripping products primarily utilize pneumatic grippers, vacuum suction, or magnetic attraction. In actual operation, it's crucial to ensure synchronized pneumatic rotation, vacuum suction, or magnetic attraction at each station. This necessitates a synchronous drive unit. Furthermore, the relatively high manufacturing costs of pneumatic grippers, vacuum suction, and magnetic attraction structures contribute to the overall high cost of the automated material handling device. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a multi-station automatic material handling device that employs a mechanical mechanism. Each individual gripping unit has no actuator, and multiple stations can grip simultaneously, ensuring stable product gripping and reducing manufacturing costs.

[0004] A multi-station automatic material handling device, characterized in that it comprises:

[0005] The material picking disc assembly includes a material picking disc, several sets of gripper mechanisms, and an upper drive frame. The upper drive frame is connected to the upper convex central shaft of the material picking disc via a connecting shaft. Several sets of gripper mechanisms are evenly distributed on the outer ring of the lower surface of the material picking disc.

[0006] frame;

[0007] A feeding disc includes an upper disc and a lower lifting disc. The outer ring of the upper surface of the feeding disc is evenly distributed with several material feeding grooves. Each material feeding groove is used to place corresponding materials, and the upper part of the materials protrudes above the material feeding groove. The lower lifting disc is arranged below the upper disc and is lifted by a lifting mechanism. A servo drive motor is connected to the bottom center of the upper disc, and the servo drive motor drives the upper disc to rotate.

[0008] Feeding track;

[0009] And vibrating discs;

[0010] The frame is provided with a mounting base, the mounting base is provided with a servo drive motor and a lifting mechanism, the mounting base is provided with a feeding disc, and a vibrating plate is also provided on one side of the frame. The output end of the vibrating plate is connected to a discharge trough at a radial position of the upper disc through a feeding rail. In the working state, each set of gripper mechanisms is correspondingly set directly above the discharge trough.

[0011] Each feeding trough of the feeding disc has a notch on both sides. The lower lifting disc has an upward-protruding guide block at the position corresponding to each notch. When the upward-protruding guide block is protruding, the clamping distance of the gripper mechanism is greater than the two sides of the material and cannot be clamped. In the material picking state, the upward-protruding guide block is retracted and the gripper mechanism clamps the two sides of the material. In the feeding state, the upward-protruding guide block is located below the notch, and the upper disc rotates to make the vibrating disc feed the feeding trough.

[0012] Its further features are:

[0013] Each set of gripper mechanisms includes an upper connecting block, N guide posts, and two clamping blocks, where N is a natural number greater than or equal to 2. The upper part of the upper connecting block is fixed to the corresponding position of the outer ring of the material picking disc. N guide posts are installed through the upper connecting block. A clamping block is set on each side of the upper connecting block. The upper part of each clamping block is sleeved on the guide post on the corresponding side. A linear spring is sleeved on each side of each guide post. The outer side of each linear spring is fixed to the end locking head of the guide post. The inner side of each guide post is fixed to the corresponding outer side of the clamping block. The clamping blocks arranged in pairs clamp inward under the action of the linear spring.

[0014] The bottom of the clamping block is a sloping surface set from the outside to the inside upwards, and the upper surface of the convex guide block is a guide slope from top to bottom from near the discharge trough to away from the discharge trough. This ensures that the clamping block gradually clamps or releases, and prevents instantaneous clamping that could damage the material.

[0015] Preferably, N is 2, the two guide posts are arranged vertically and are located at the center of the width direction of the clamping block;

[0016] The lifting mechanism specifically consists of two sets of lifting cylinders, which are arranged on both sides of the same diameter of the lower lifting plate, and the two sets of lifting cylinders operate synchronously.

[0017] With the structure of this invention, in the feeding state, the convex guide block of the lower lifting plate disengages from the notch groove, and the vibrating plate transports the materials one by one into the corresponding feeding slot of the feeding disc via the feeding track. At this time, the servo drive motor drives the feeding disc to rotate stepwise. After all the materials are filled, the lower lifting plate rises under the drive of the lifting mechanism, causing the convex guide block to convex upward. Then, the picking disc assembly is positioned directly above the feeding disc under the drive of the external drive component, and each gripper mechanism corresponds to a set of convex guide blocks and materials directly below. Then each gripper... Driven by the descent of the external drive component, the gripper mechanism opens the gripper mechanism via the upper convex guide block, keeping the gripping components of the gripper mechanism and the two side plates of the material within the overlapping height area. Then, the lifting mechanism drives the upper convex guide block to fall, and the gripping components of the gripper mechanism hold the two sides of the material. Then, under the action of the external drive component, the material picking disc assembly detaches from the feeding disc and places the material at the rear station. It adopts a mechanical mechanism, with no execution unit in a single gripping unit, and multiple stations gripping simultaneously, ensuring stable product gripping and reducing manufacturing costs.

Detailed Implementation

[0023] A multi-station automatic material handling device, see Figures 1-3 It includes a material handling disc assembly 10, a frame 20, a feeding disc 30, a feeding track 40, and a vibrating plate 50;

[0024] The material handling disc assembly 10 includes a material handling disc 11, several sets of gripper mechanisms 12, and an upper drive frame 13. The upper drive frame 13 is connected to the upper convex central shaft of the material handling disc 11 via a connecting shaft. Several sets of gripper mechanisms 12 are evenly distributed on the outer ring of the lower surface of the material handling disc 11. Each set of gripper mechanisms 12 includes an upper connecting block 1, N guide posts 2, and two clamping blocks 3, where N is a natural number greater than or equal to 2. The upper part of the upper connecting block 1 is fixedly connected to the corresponding position of the outer ring of the material handling disc 11. The upper connecting block 1 is equipped with N guide posts 2. A clamping block 3 is set on each side of the upper connecting block 1. The upper part of the clamping block 3 is sleeved on the guide post 2 on the corresponding side. A linear spring 4 is sleeved on each side of each guide post 2. The outer side of each linear spring 4 is fixed to the end locking head 5 of the guide post 2. The inner side of each guide post 2 is fixed to the corresponding outer side of the clamping block 3. The clamping blocks 3 arranged in pairs are clamped inward under the action of the linear spring 4.

[0025] The feeding disc 30 includes an upper disc 31 and a lower lifting disc 32. The outer ring of the upper surface of the feeding disc 31 is evenly distributed with a number of material feeding grooves 311. Each material feeding groove 311 is used to place the corresponding material 60, and the upper part of the material 60 protrudes above the material feeding groove 311. The lower lifting disc 32 is arranged below the upper disc 31. The lower lifting disc 32 is lifted by a lifting mechanism. A servo drive motor 33 is connected to the bottom center of the upper disc 31. The servo drive motor 33 drives the upper disc 31 to rotate.

[0026] A mounting base 21 is provided on the frame 20. A servo drive motor 33 and a lifting mechanism are provided on the mounting base 21. A feeding disc 30 is provided on the mounting base 21. A vibrating plate 50 is also provided on one side of the frame 20. The output end of the vibrating plate 50 is connected to a feeding trough at a radial position of the upper disc 31 through a feeding rail 40 (this is the feeding station. After the upper disc 31 rotates, the feeding rail 40 feeds the material one by one). In the working state, each set of gripper mechanisms 12 is correspondingly set directly above the feeding trough 311.

[0027] Each feeding trough 311 of the upper disc 31 has a notch 312 on both sides. The lower lifting disc 32 has an upward guide block 35 corresponding to the position of each notch 312. When the upward guide block 35 is upward, the clamping distance of the gripper mechanism 12 is greater than the two sides of the material 60 and cannot be clamped. In the material picking state, the upward guide block 35 is retracted and the gripper mechanism 12 clamps the two sides of the material 60. In the material feeding state, the upward guide block 35 is located below the notch 312, and the upper disc 31 rotates so that the vibrating disc 50 performs the feeding operation on the feeding trough 311.

[0028] In practice:

[0029] The upper convex guide blocks 35 on both sides of each material 60 are in a group structure. The group structure of the upper convex guide blocks 35 is connected into an integral structure through the bottom horizontal plate 36. The bottom horizontal plate of the integral structure is fixed to the corresponding position on the upper surface of the lower lifting plate 32 through fasteners.

[0030] The bottom of the clamping block 3 is a sloping surface 301 that is set from the outside to the inside upwards, and the upper surface of the convex guide block 35 is a guide slope 351 that is set from the top to the bottom of the discharge trough. The slopes of the sloping surface 301 and the guide slope 351 are the same, which ensures that the clamping block 3 gradually clamps or releases, and ensures that the material will not be damaged by instantaneous clamping.

[0031] In practice, N is 2, the two guide posts 2 are arranged vertically and are located at the center of the width direction of the clamping block 3.

[0032] The lifting mechanism consists of two sets of lifting cylinders 34, which are arranged on both sides of the same diameter of the lower lifting plate 32, and the two sets of lifting cylinders operate synchronously.

[0033] Its working principle is as follows: In the feeding state, the upper convex guide block of the lower lifting plate disengages from the notch slot, and the vibrating plate conveys the materials one by one into the corresponding feeding slot of the feeding disc through the feeding track. At this time, the servo drive motor drives the feeding disc to rotate step by step. After all the materials are filled, the lower lifting plate rises under the drive of the lifting mechanism, causing the upper convex guide block to convex. Then, the picking disc assembly is positioned directly above the feeding disc under the drive of the external drive component, and each gripper mechanism corresponds to a set of upper convex guide blocks and materials directly below. Then, each gripper mechanism is lowered by the external drive component. The lifting mechanism lowers the upper guide block to open the clamping block, keeping the two clamping blocks and the two side plates of the material within the overlapping height area. Then, the lifting mechanism drives the upper guide block to fall, and the two clamping blocks of the gripper mechanism clamp the two sides of the material under the elastic force of the linear spring. Then, under the action of the external drive, the material picking disc assembly is completely separated from the feeding disc and the material is placed in the rear station. It adopts a mechanical mechanism, with no execution unit in a single gripping unit, and multiple stations gripping simultaneously. The linear spring is used to provide clamping force, ensuring stable product gripping and reducing manufacturing costs.
