[0003] However, in order to meet the needs of automatic picking up by the robot gripper, the product storage method needs to be adjusted, but this adjustment will affect the size and storage capacity of the material frame. If the existing hair cover assembly material frame is to realize automatic picking up by the robot gripper, the product parts need to be arranged and distributed vertically. However, the material frame size required for the vertical arrangement of products is larger, and a single frame can store fewer product parts, which affects the beat of the entire line.

[0010] The material frame limiting block is used to fix the hair cover assembly in the hair cover assembly material frame, so that the hair cover assembly can be grasped by the hair cover assembly gripper;

[0011] When the gripper of the hair cover assembly clamps the workpiece, the telescopic roller device at the gripper extends out and pushes the material frame limit block to flip downward and separate from the workpiece, so that the workpiece is taken out.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] Example

[0030] If the existing hair cover assembly material frame is to realize automatic picking up by the robot gripper, the product parts need to be arranged and distributed in the vertical direction. However, the material frame size required for the vertical arrangement and distribution of the products is larger, and a single frame can store fewer product parts, which affects the rhythm of the entire line.

[0031] This embodiment provides a gripper mechanism for realizing automatic picking up of product racks by grippers, so that the gripper can also realize automatic picking up of product parts when the product parts are arranged horizontally in the material frame, so that a single material frame can hold more complete hair cover assemblies assembled with seals, bolts and other accessories, with a simple structure and easy production.

[0032] Specifically, Figure 1-Figure 4 As shown, the mechanism provided in this embodiment mainly includes: a cover assembly material frame 1, a cover assembly gripper 2, a material frame limit block 3, and a telescopic roller device 4 at the gripper.

[0033] Among them, the cover assembly material frame 1 is as follows Figure 1 As shown, it is used to store and fix the hair cover assembly and provide a stable placement environment. The hair cover assembly is stored in the hair cover assembly material frame 1 to meet the needs of automatic grasping and wait for the robot to grasp it.

[0034] Hair cover assembly gripper 2 Figure 3 As shown, it is used to grip and carry the hair cover assembly. The hair cover assembly gripper 2 is controlled by the robot and goes to the hair cover assembly material frame 1 to position the hair cover assembly. The hair cover assembly gripper 2 clamps the workpiece by mechanical clamping, vacuum adsorption or other means to ensure stable picking. After gripping, subsequent handling or assembly operations are performed.

[0035] Material frame limit block 3 Figure 1 , 2As shown, it is used to fix the hair cover assembly during the storage stage to prevent it from moving or tilting. When the hair cover assembly is stored in the hair cover assembly material frame 1, the material frame limit block 3 can play a restraining role to prevent the workpiece from being affected by the hair cover assembly gripper 2 due to vibration or tilt.

[0036] Furthermore, the hair cover assembly material frame 1 includes a plurality of material frame limit blocks 3, and the material frame limit blocks 3 are symmetrically arranged on both sides of the material frame limit blocks 3. The plurality of limit blocks can evenly distribute the force to ensure that the hair cover assembly is stable during storage and will not tilt or shake due to uneven force on one side. In addition, the material frame limit block 3 is a rotatable nylon block, which can reduce the risk of friction and damage. The low friction coefficient and wear resistance of the nylon material are used to reduce the friction between the workpiece and the block, thereby avoiding scratches on the surface of the hair cover assembly. At the same time, the rotating nylon block can automatically rotate when the workpiece needs to be released, making it easier for the workpiece to be detached than a fixed block, thereby improving the smoothness of the retrieval. The rotating design reduces the problem of workpiece jamming that may be caused by the fixed block, thereby improving the success rate of retrieval.

[0037] The retractable roller device 4 at the gripper is as follows Figure 4 As shown, it is used to push the limit block away from the workpiece so that the workpiece can be taken out smoothly. When the hair cover assembly gripper 2 takes the workpiece, the telescopic roller device 4 at the gripper serves as a release mechanism to separate the limit block from the workpiece, ensuring smooth grasping. Specifically, after the hair cover assembly gripper 2 clamps the workpiece, the telescopic roller device 4 at the gripper will extend and push the material frame limit block 3 at the same time. The material frame limit block 3 flips downward after being subjected to force, so that the workpiece loses its constraint and can be taken out smoothly without being blocked or stuck by the limit block. The telescopic roller device 4 at the gripper can use a standard roller for easy replacement.

[0038] The production process of the mechanism provided in this embodiment is briefly described as follows:

[0039] The hair cover assembly material is stored in the hair cover assembly material frame 1. The hair cover assembly gripper 2 is controlled by the robot to grab the material in the hair cover assembly material frame 1. After clamping the material, the telescopic roller device 4 at the gripper extends out, pushing the material frame limit block 3 to separate from the workpiece and flip downward, and then the hair cover assembly gripper 2 grabs the workpiece and leaves to enter the next process.

[0040] The mechanism provided in this embodiment, through the interactive form of the material frame assembly limit block and the telescopic roller device at the gripper, allows the product parts to be arranged horizontally in the material frame, so that a single material frame can hold more hair cover assemblies, and when the hair cover assemblies are arranged horizontally, the gripper can also automatically grab the product parts, the structure is streamlined, and the production is convenient.

[0041] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
