A clamping plate structure of a clamping jaw

Abstract

The application relates to the technical field of automatic dishwashers, and particularly discloses a clamping plate structure of a clamping jaw, which comprises a first clamping plate, and one or two protrusions with flexibility and / or elasticity are arranged on the first clamping plate. Two larger protrusions are arranged in the application, so that the surfaces of the two protrusions can fully contact with tableware (clamped objects) during clamping, so that the clamping friction and stability are increased; even if the contact positions of the clamped tableware and the two protrusions are curved surfaces or complex curved surfaces, the deformation characteristics of the flexible materials of the two protrusions can make the curved surfaces or complex curved surfaces of the clamped tableware fully contact with the two protrusions, so that the clamping friction and stability are further increased.

Description

Technical Field

[0001] This application relates to the field of automatic dishwasher gripper technology, specifically to a gripper clamping plate structure. Background Technology

[0002] Grippers are typically used to transfer objects. To be suitable for more scenarios, their grippers are usually flat. To increase friction with the object and prevent it from falling, a rubber protective sleeve is usually installed on the gripper, and this protective sleeve is textured (see [reference]). Figure 10 (These typically feature numerous small bumps, grids, or raised strips). In automatic dishwashers, the items being handled include bowls; see [link / reference]. Figure 6 Some bowls are shaped like an inverted frustum, resembling a V-shape when viewed from the side. Therefore, see [reference needed]. Figures 11 to 12 Even though the existing rubber protective sleeve has many raised strips or dots, only a small portion of the raised strips or dots can actually contact the bowl during actual clamping (see the contact area for details). Figure 12 (At point D in the middle), most of the protrusions or dots do not touch the bowl at all, so they cannot play their role. Therefore, when actually clamping, the part of the clamp that comes into contact with the object is very small and the friction between the two is also small. This makes it easy to fall and difficult to clamp the object stably. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this application is to provide a clamping plate structure for a gripper to solve these problems.

[0004] To achieve the above objectives, this application adopts the following technical solution: a clamping plate structure for a gripper, the clamping plate structure including a first clamping plate, the first clamping plate having one or two protrusions with flexibility and / or elasticity.

[0005] Furthermore, the protrusion is directly disposed on the first clamping plate, or the protrusion is disposed on the protective sleeve of the first clamping plate.

[0006] Furthermore, the clamping structure also includes a second clamping plate disposed opposite to the first clamping plate, and the second clamping plate is also provided with one or two protrusions that are flexible and / or elastic.

[0007] Furthermore, the protrusion is textured.

[0008] Furthermore, the first clamp has exactly two of the aforementioned protrusions.

[0009] Furthermore, the side of the protrusion that contacts the object being clamped is a plane.

[0010] Beneficial effects: See below Figures 1 to 9This application features two flexible protrusions on the clamping plate, thus avoiding the impact of curvature on the handling of tableware when gripping it. Figure 11 and Figure 12 In cases where the clamping device only has a very small contact area with the cutlery, this application allows the two raised surfaces to fully contact the cutlery (the object being clamped), thereby increasing the clamping friction and stability; see reference Figure 9 Because the two protrusions are made of a flexible material, when the cutlery being gripped comes into contact with the two protrusions under the action of force, even if the contact area between the cutlery being gripped and the two protrusions is a curved or complex curved surface, the deformation characteristics of the flexible material of the two protrusions can make the curved or complex curved surface of the cutlery being gripped come into complete contact with the two protrusions, which further increases the gripping friction and stability.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] In view of the problems existing in the prior art, this application provides a clamping plate structure for a gripper to solve the problem, which will be described in detail below with reference to the accompanying drawings. It should be explained that... (Refer to...) Figure 2 The gripper of this application includes two sets of gripping fingers, namely a first gripping finger 100 and a second gripping finger 200. The first gripping finger 100 and the second gripping finger 200 each include a first clamping plate 10 and a second clamping plate 20. The first gripping finger 100 and the second gripping finger 200 can grip an object under their combined action. The first clamping plate 10 and the second clamping plate 20 are used to contact the object being gripped during gripping. Optionally, the first gripping finger 100 and the second gripping finger 200 may be provided with multiple clamping plates, for example, see [reference needed]. Figure 3 Set up 4 clamps.

[0025] In one embodiment, see Figures 1 to 5 The clamping structure provided in this application includes: a first clamping plate 10, on which one or two flexible and / or elastic protrusions 30 (also called bosses or protrusions) are provided; the clamping structure also includes a second clamping plate 20, on which one or two flexible and / or elastic protrusions 30 are provided. Figure 2 , 3 As shown, in the first clamping plate 10, a protrusion 30 is located at the lower end of the clamping plate. The side of the protrusion 30 that contacts the object being clamped is flat, allowing it to clamp chopsticks and spoons. The clamping plate structure also includes a protective sleeve 11 for the first clamping plate and a protective sleeve 21 for the second clamping plate. It should be explained that the protrusion 30 can be directly provided on the first clamping plate 10 and the second clamping plate 20 (see...). Figure 3Alternatively, protrusions 30 can be provided on the protective sleeve 11 of the first clamping plate and the protective sleeve 21 of the second clamping plate (see reference). Figure 2 The first clamping plate 10 and the second clamping plate 20 are arranged opposite each other and are both rigid bodies, which ensures sufficient clamping force. Therefore, when clamping tableware with a slight curvature, the curvature can be avoided, preventing issues such as... Figure 11 and Figure 12 In the event of an unfavorable situation (when picking up cutlery, only a very small area of ​​the clamp is in contact with the cutlery), this application allows the two raised surfaces to make full contact with the object being picked up (cutlery) (see...). Figure 9 This increases the gripping friction and stability. These protrusions 30 can be made of rubber, latex, silicone, or other flexible or elastic materials (such as EVA or PU). The protective sleeves of the two clamps are also typically made of flexible or elastic materials like rubber. This allows the protrusions to deform upon contact with an object, increasing the contact area and making the object less likely to fall out, resulting in a more stable grip. For details, please refer to [link to relevant documentation]. Figure 9 When the clamped cutlery (object) comes into contact with the two protrusions under the action of force, even if the contact area between the clamped cutlery and the two protrusions is a curved or complex curved surface, the deformation characteristics of the flexible material of the two protrusions can ensure that the curved or complex curved surface of the clamped cutlery comes into complete contact with the two protrusions, further increasing the gripping friction and stability. (See also...) Figure 9 In the sectional view, point C is highlighted with a bold line. Point C represents the contact surface between the clamping structure and the object being clamped. It is clearly visible that the protrusion makes full contact with the surface of the bowl, resulting in a large contact area. The protrusion on the clamping plate supports the object being clamped, meaning it directly applies an upward vertical force to the object, thus offsetting part of its weight. Ultimately, it can be easily clamped without requiring greater pressure, preventing the object from easily falling.

[0026] Further, see Figures 1 to 3 To better grip bowls or other tableware, it is best to have only two protrusions on the first clamping plate 10 and / or the protective sleeve 11 of the first clamping plate; and also to have two protrusions on the corresponding second clamping plate 20 and / or the protective sleeve 21 of the second clamping plate. (See reference...) Figures 6 to 9 ,because Figure 6The bowl in the bowl is curved. If an additional protrusion is added, the extra protrusion may obstruct the contact between the original two protrusions and the bowl, resulting in insufficient contact between the protrusions and the tableware, ultimately reducing the contact area and having a counterproductive effect. Therefore, it is best to only provide two protrusions. Optionally, the protrusions on the first clamping plate 10 and the protrusions on the second clamping plate 20 are staggered, or the protrusions on the protective sleeve 11 of the first clamping plate and the protective sleeve 21 of the second clamping plate are staggered. The protrusions are not arranged one-to-one opposite each other, but are distributed in a staggered manner. This allows the pressure between the clamping plate and the object being clamped to be distributed more evenly during clamping, making the clamping more stable. Preferably, a texture can be provided on the protrusions. The texture can be a raised or recessed texture or multiple grooves, such as "herringbone" grooves R, like the fingerprints of a human finger. This can also increase friction and make the clamping more stable.

[0027] Furthermore, the object being gripped in this application is tableware in an automatic dishwasher or dishwasher robot. The grippers are used to transfer the tableware to be washed from the dirty area to the cleaning area. In this case, the clamps and / or the protective covers on the clamps will inevitably get greasy. Unlike the prior art which has many small protrusions / strips (because the protrusions / strips are small and dense, they are easy to leave stains and are not easy to clean), this application only has one or two protrusions. Therefore, it is easier to clean when it gets greasy and is less likely to leave stains.
