Definitions

  • the invention relates to a clamping device for gripping, clamping and repeatable positioning of a flat material extending along a material plane.
  • flat materials are understood to mean single or multi-layered layers or films, whereby the layers or films have a significantly greater longitudinal and transverse extent than one thickness.
  • the flat material is designed to be flexible, so that the flat material deviates significantly from a flat shape without support over the longitudinal and transverse extent.
  • the flat material is at least essentially impermeable to gas, so that the flat material can be sucked in.
  • the flat material or its layers are designed to be monolithic.
  • the flat materials can in particular comprise plastic or metal, with metal-coated plastics or plastic-coated metals also being conceivable.
  • the flat material can be designed as a flat material strip section.
  • the flat material can be, for example, a current collecting foil with the dimensions 200 mm x 280 mm, with the foil comprising graphite and being coated with aluminum or copper.
  • the invention is therefore based on the object of providing a clamping device for simple, safe and reproducible gripping and clamping of flat material.
  • the object underlying the invention is achieved by a clamping device with the features of claim 1.
  • the clamping device has at least two pairs of clamping jaws lying opposite one another, the pairs of clamping jaws each having a first clamping jaw extending parallel to a clamping axis and a second clamping jaw extending parallel to the clamping axis.
  • the first clamping jaw is preferably designed in one piece.
  • the second clamping jaw is preferably designed in one piece.
  • the first clamping jaw is preferably arranged above the flat material to be clamped and the second clamping jaw is preferably arranged below the flat material to be clamped or vice versa.
  • the first clamping jaw and/or the second clamping jaw can be pivoted between an open position and a closed position about a clamping rotation axis.
  • a flat material can be made available in the clamping device and removed from the clamping device.
  • the flat material is gripped and secured by the clamping device.
  • the clamping axis and the clamping rotation axis run parallel to the material plane.
  • the clamping rotation axis runs parallel to the clamping axis.
  • the first jaw has a first clamping surface and the second jaw has a second clamping surface.
  • the first clamping surface and the second clamping surface each have at least a first section for gripping the flat material in the material plane in the closed position, at least a second section for deforming the flat material out of the material plane and clamping the flat material in the closed position, and at least a third section for providing a cavity to accommodate distortions of the flat material when clamping in the closed position.
  • the flat material has to travel a longer distance, so that a tensile force occurs between the pairs of clamping jaws. This is further reinforced by the fact that the flat material is clamped in the material plane at the first section and deformed out of the material plane at the second section.
  • the first clamping jaw has, as a second section, a clamping element that protrudes relative to the first section and/or the third section of the first clamping jaw.
  • the clamping element extends along the clamping axis and preferably has a constant cross-section.
  • the second clamping jaw has, as a second section, a clamping element that protrudes relative to the first section of the second
  • the clamping jaw has a clamping recess set back.
  • the clamping recess extends along the clamping axis and preferably has a constant cross-section.
  • the clamping element and/or the clamping recess is preferably formed in one piece with the respective clamping jaw.
  • the clamping recess receives the clamping element or the clamping element engages in the clamping recess so that a flat material provided in the clamping device is gripped and clamped at the same time. Due to the longer path that the flat material has to travel in the area of the clamping element and the clamping recess, gripping the flat material also clamps the flat material at the same time. This ensures that when the flat material is secured in the clamping device, the conditions for safely processing the flat material are already in place, in particular by preventing unwanted distortions or overlaps in the flat material.
  • the pair of clamping jaws has an opening angle of at least 90°, in particular of at least 130°, preferably of at least 150°, and preferably of at least 180°.
  • the clamping device is preferably designed in the shape of a mouth. The movement of the lower jaw, in particular of the second jaw, over at least 45°, preferably over at least 90°, ensures that a flat material provided can be securely gripped.
  • the flat material provided is lifted and one end of the flat material is moved into the engagement area of the clamping device. The larger the opening angle is by pivoting the upper jaw, the easier it is to provide a flat material to the clamping device.
  • the first clamping jaw has a first web section and a second web section as first sections.
  • the first web section and/or the second web section preferably extend parallel to the clamping axis and, in particular, when the flat material is gripped in the clamping device, parallel to the material plane.
  • the clamping element is arranged between the first web section and the second web section.
  • the clamping element preferably also protrudes relative to the first web section and/or the second web section.
  • the first web section preferably has a first web width and/or a first web height.
  • the second web section preferably has a second web width and/or a second web depth.
  • the first clamping jaw has a first groove section and a second groove section as third sections.

It is also advantageous if the clamping element is arranged between the first groove section and the second groove section.
  • the first groove section and/or the second groove section is set back from the clamping element and/or the first web section and/or the second web section. In the closed position, the first groove section and the second groove section each form a cavity that is delimited in particular by the clamping surface, the clamping element and the associated web section.
  • the clamping element and the clamping recess can cause distortions and deformations of the flat material in the area of the clamping element and the clamping recess. If a gripping force is then exerted on this area in addition to the clamping element, the flat material can be damaged and possibly tear.
  • the flat material can extend into the cavity provided by the first groove section and the second groove section without being subjected to stress. The flat material can thus be gripped and clamped particularly gently.
  • the flat material is preferably not contacted by the second clamping jaw.
  • the first groove section and the second groove section are preferably set back from the gripped flat material. If no flat material is clamped, the first clamping jaw and the second clamping jaw do not come into contact in the closed position in the area of the first groove section and/or the second groove section.

  • the first web height and the first groove depth preferably have a ratio between 1:0.5 and 1:2, in particular between 1:0.8 and 1:1.5, preferably between 1:0.9 and 1:1.1.
  • the second web height and the second groove depth have a ratio between 1:0.5 and 1:2, in particular between 1:0.8 and 1:1.5, preferably between 1:0.9 and 1:1.1.
  • first groove section is arranged between the first web section and the clamping element. It is advantageous if the second groove section is arranged between the second web section and the clamping element.
  • the first groove section preferably borders on the one hand on the first web section and on the other hand on the clamping element.
