Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a scratch-resistant sleeve for robotic arms. Background Technology

[0002] As core equipment in fields such as automated production, logistics transfer, and precision assembly, robotic arms have significantly improved production efficiency and operational safety due to their efficient and precise gripping and handling capabilities. In practical applications, robotic arms often need to grip and transfer items of various materials. However, the gripping parts of traditional robotic arms are mostly made of metal, resulting in hard contact between them and the items being transferred.

[0003] This rigid contact structure has significant drawbacks: on the one hand, for items requiring high surface finish, the mechanical arm is prone to leaving scratches and indentations on the surface of the item due to metal-to-metal friction or pressure concentration, leading to product scrap or quality degradation; on the other hand, for brittle items, rigid clamping may directly cause the item to break, increasing production costs.

[0004] To avoid such situations, some existing robotic arms use simple methods such as wrapping cloth strips or sticking foam to prevent scratches. However, these methods have obvious limitations: First, they have poor fixation, and the cloth strips and foam are easy to fall off during frequent clamping, requiring repeated replacement and affecting the continuity of operation. Second, they have low adaptability, making it difficult to fit the complex shape of the robotic arm's clamping part, and there is still a risk of local hard contact.

[0005] Therefore, a scratch-resistant sleeve for robotic arms is proposed. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] In view of the problems of poor fixation and low adaptability of the existing anti-scratch treatment methods in the prior art, the present invention aims to provide an anti-scratch sleeve for robotic arms to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A scratch-resistant sleeve for a robotic arm includes: a heat-shrink sleeve; A limiting component is disposed at the bottom of the front side of the heat shrink sleeve; A plug-in assembly, wherein the plug-in assembly is disposed on the inner side of the limiting assembly; Two splicing components are respectively disposed on both sides of the inner side of the plug-in component; A clamping assembly disposed on the front side of the plug-in assembly; Two reset components are respectively disposed at the top and bottom of the inner side of the plug-in component.

[0009] As a further embodiment of this utility model: the limiting component includes a limiting frame, a limiting groove and two insertion grooves. The limiting frame is fixedly installed on the front side of the heat shrink sleeve, the limiting groove is opened on the front side of the limiting frame, and the two insertion grooves are respectively opened on both sides of the inner side of the limiting groove.

[0010] As a further embodiment of this utility model: the plug-in assembly includes a mounting frame, two first through slots and two second through slots, the mounting frame is plugged into the inner side of the limiting slot, and the two first through slots and the two second through slots are all opened on both sides of the mounting frame.

[0011] As a further embodiment of this utility model: both splicing components include a movable plate, a plug-in plate, and a pressing plate. The movable plate is disposed on the inner side of the mounting frame. The plug-in plate and the pressing plate are both fixedly installed on one side of the movable plate. The plug-in plate is slidably connected to the inner side of the first through groove. The pressing plate is slidably connected to the inner side of the second through groove. The plug-in plate is snapped into the inner side of the plug-in groove.

[0012] As a further embodiment of this utility model: the clamping assembly includes a connecting block, a fixing plate, a rubber sleeve, and an anti-slip strip. The connecting block is fixedly installed on the front of the mounting frame, the fixing plate is fixedly installed on the front of the connecting block, the rubber sleeve is fixedly installed on the outer side of the fixing plate, and the anti-slip strip is fixedly installed on the front of the rubber sleeve.

[0014] As a further embodiment of this utility model: the movable plate is slidably connected to the outer side of the slide rod, and the movable plate is disposed at one end of the spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a combination of heat shrink tubing, limiting components, plug-in components, splicing components, and clamping components. During use, the heat shrink tubing fits snugly against the gripping area of ​​the robotic arm, allowing for complete installation. The plug-in connection between the limiting components and the plug-in components enables rapid installation and removal of the tubing, improving work efficiency. The splicing components, under the action of the reset components, automatically engage and secure the tubing, ensuring a firm installation and preventing it from falling off. The clamping components' rubber sleeves are made of flexible material, providing flexible gripping when in contact with objects to prevent scratches.

By setting up a reset component, this utility model provides a sliding guide for the moving plate during use. The spring can be compressed and stored when the pressing plate is under force, and the elastic potential energy is released after the external force is removed to push the moving plate to reset, so that the plug-in plate automatically snaps into the plug-in slot. This realizes the quick disassembly and automatic fixation of the plug-in component and the limiting component. This structure solves the problem of easy detachment of the fixing parts in the existing anti-scratch treatment method. Installation and disassembly can be completed without tools, which improves work efficiency. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present utility model. This embodiment provides a scratch-resistant sleeve for a robotic arm, including: a heat-shrink sleeve 1; Limiting component 2 is located at the bottom of the front side of the heat shrink sleeve 1; The plug-in component 3 is disposed on the inner side of the limiting component 2; Two splicing components 4 are respectively disposed on both sides of the inner side of the plug-in component 3; Clamping component 5 is disposed on the front side of plug-in component 3; Two reset components 6 are respectively located at the top and bottom of the inner side of the plug-in component 3.

[0022] For example, the limiting component 2 includes a limiting frame 21, a limiting groove 22 and two insertion grooves 23. The limiting frame 21 is fixedly installed on the front side of the heat shrink sleeve 1, the limiting groove 22 is opened on the front side of the limiting frame 21, and the two insertion grooves 23 are respectively opened on both sides of the inner side of the limiting groove 22.

[0023] Furthermore, the limiting frame 21 is used to provide an installation base for the plug-in component 3, the limiting groove 22 can limit the installation frame 31 to ensure the accurate installation position of the plug-in component 3, and the plug-in groove 23 cooperates with the plug-in plate 42 to realize the snap-fit ​​fixation between the splicing component 4 and the limiting component 2.

[0024] For example, the plug-in component 3 includes a mounting frame 31, two first through slots 32 and two second through slots 33. The mounting frame 31 is plugged into the inner side of the limiting slot 22, and the two first through slots 32 and the two second through slots 33 are all opened on both sides of the mounting frame 31.

[0025] Furthermore, the mounting frame 31 and the limiting groove 22 are connected and engaged, which enables the quick installation and disassembly of the plug-in component 3 and the limiting component 2. The first through groove 32 provides a channel for the sliding of the plug-in plate 42, and the second through groove 33 provides space for the sliding of the pressing plate 43.

[0026] For example, both splicing components 4 include a movable plate 41, a plug-in plate 42, and a pressing plate 43. The movable plate 41 is disposed on the inner side of the mounting frame 31. The plug-in plate 42 and the pressing plate 43 are both fixedly installed on one side of the movable plate 41. The plug-in plate 42 is slidably connected to the inner side of the first through groove 32, and the pressing plate 43 is slidably connected to the inner side of the second through groove 33. The plug-in plate 42 is snapped into the inner side of the plug-in groove 23.

[0027] Furthermore, when it is necessary to install the plug-in component 3, push the pressing plate 43 to move the moving plate 41 and the plug-in plate 42. After inserting the mounting frame 31 into the limiting groove 22, release the pressing plate 43. Under the action of the reset component 6, the plug-in plate 42 is inserted into the plug-in groove 23 to achieve fixation.

[0028] For example, the clamping assembly 5 includes a connecting block 51, a fixing plate 52, a rubber sleeve 53, and an anti-slip strip 54. The connecting block 51 is fixedly installed on the front of the mounting frame 31, the fixing plate 52 is fixedly installed on the front of the connecting block 51, the rubber sleeve 53 is fixedly installed on the outer side of the fixing plate 52, and the anti-slip strip 54 is fixedly installed on the front of the rubber sleeve 53.

[0029] Furthermore, the connecting block 51 is used to connect the mounting frame 31 and the fixing plate 52. The fixing plate 52 provides a mounting carrier for the rubber sleeve 53. The rubber sleeve 53 is made of flexible material, which can avoid hard contact with the object and prevent scratches. The anti-slip strip 54 can increase the friction during clamping and improve the clamping stability.

[0030] In use, first, the heat shrink sleeve 1 is put on the gripping part of the robotic arm and heated to shrink it tightly; then, the mounting frame 31 of the plug-in component 3 is inserted into the limiting groove 22. Under the action of the reset component 6, the plug plate 42 of the splicing component 4 is automatically inserted into the plug-in groove 23, completing the installation of the sleeve; when the robotic arm grips an item, the rubber sleeve 53 and anti-slip strip 54 of the gripping component 5 come into contact with the item to achieve flexible gripping and prevent scratches.

[0031] In summary, through the coordinated operation of heat shrink tubing 1, limiting component 2, plug-in component 3, splicing component 4, and clamping component 5, the heat shrink tubing 1 can tightly fit the clamping part of the robotic arm during use, thereby installing the entire tubing; the plug-in cooperation between limiting component 2 and plug-in component 3 enables quick installation and removal of the tubing, improving work efficiency; splicing component 4, under the action of reset component 6, can automatically snap and fix, ensuring that the tubing is firmly installed and preventing it from falling off; the rubber sleeve 53 of clamping component 5 is made of flexible material, which can achieve flexible clamping when in contact with objects to prevent scratches, and the anti-slip strip 54 can increase friction and improve clamping stability. This structure solves the problems of poor fixation and low adaptability of existing anti-scratch treatment methods, and improves the continuity and reliability of operations.

[0032] Example 2: Please see Figure 3 This is the second embodiment of the present utility model.

[0033] For example, both reset components 6 include a slide rod 61 and a spring 62. The slide rod 61 is fixedly installed on the inner side of the mounting frame 31, and the spring 62 is sleeved on the outer side of the slide rod 61.

[0034] Furthermore, the slide bar 61 is used to guide the sliding of the movable plate 41. The spring 62 is sleeved on the slide bar 61 and can be compressed when the pressing plate 43 is subjected to force to store elastic potential energy. When the external force is removed, the spring 62 releases the elastic potential energy and pushes the movable plate 41 to reset.

[0035] For example, the movable plate 41 is slidably connected to the outer side of the slide rod 61, and the movable plate 41 is disposed at one end of the spring 62.

[0036] Furthermore, the movable plate 41 can slide on the slide bar 61. When the pressing plate 43 is pressed, the movable plate 41 compresses the spring 62. When the pressing plate 43 is released, the spring 62 pushes the movable plate 41 to reset, causing the plug plate 42 to be inserted into the plug slot 23.

[0037] When in use, if the sleeve needs to be disassembled, press the pressing plate 43, the moving plate 41 slides on the slide rod 61 and compresses the spring 62, which drives the plug plate 42 to disengage from the plug groove 23, so that the plug assembly 3 can be taken out from the limiting groove 22; during installation, insert the plug assembly 3 into the limiting groove 22, the spring 62 pushes the moving plate 41 to reset, so that the plug plate 42 is locked into the plug groove 23, and automatic fixation is achieved.

[0038] In summary, by setting the reset component 6, during use, the slide bar 61 provides a sliding guide for the moving plate 41, and the spring 62 can compress and store energy when the pressing plate 43 is under force. After the external force is removed, the elastic potential energy is released to push the moving plate 41 to reset, so that the plug plate 42 automatically snaps into the plug slot 23, realizing the quick disassembly and automatic fixation of the plug component 3 and the limiting component 2. This structure solves the problem of easy detachment of the fixing parts in the existing anti-scratch treatment method, and can complete the installation and disassembly without tools, thus improving the work efficiency.
