Description

Technical Field

[0001] The utility model relates to the technical field of ground-mouth glass bottle processing, in particular to a unloading manipulator clamping mechanism for ground-mouth glass bottle processing. Background Art

[0002] Bottles with frosted glass mouths and stoppers are ground-mouth bottles. The stoppers of ground-mouth bottles can only be covered but not tightened, so their seals are not very tight. They are generally not used to hold medical drugs, but can be used to hold chemical reagents (except alkalis, which will react with glass to form sodium metasilicate and cause the bottle mouth to stick). In the process of processing ground-mouth glass bottles, a unloading robot clamping mechanism is usually used to clamp the ground-mouth glass bottles for unloading.

[0003] The unloading robot clamping mechanism for processing ground-mouth glass bottles is usually used in conjunction with a clamping piece through an inflator. The inflator inflates air into the clamping piece, causing the airbag in the clamping piece to swell. The swollen airbag acts on the inner wall of the ground-mouth glass bottle, which can clamp the ground-mouth glass bottle without damaging the ground-mouth glass bottle. After the transfer is completed, the inflation is stopped, so that the clamping piece cancels the positioning of the ground-mouth glass bottle. However, there are many types of ground-mouth glass bottles, and the corresponding clamping pieces are of different sizes. If the clamping piece is not easy to replace, the utilization efficiency of the unloading robot clamping mechanism for processing ground-mouth glass bottles may be reduced. Therefore, in response to the above problem, a unloading robot clamping mechanism for processing ground-mouth glass bottles is proposed. Utility Model Content

[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0024] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
