Abstract
The invention relates to a seal for a sawing machine (1) for separating electronic components (12), comprising: an elongate form-retaining holder (20,22), a flexible, elongate expandable body (8,9)and a pressure source (24) for a medium, wherein the elongate expandable body (8,9) is provided with a strengthened elongate edge (21) which lies clear of the form-retaining holder (20,22) The invention also relates to a sawing machine (1) for separating electronic components (12) provided with such a seal.
Claims12
A sawing machine for separating electronic components, comprising:
- at least one rotatable saw-blade placed in a housing, and
- a product holder displaceable over an upper part of the saw-blade,
- wherein the housing is provided on an upper side with a slot for admitting at least the part of the product holder holding the electronic components into the housing in displaceable manner, wherein the slot is closable by a seal, and
- further wherein the displaceable product holder is carried on an upper side by a rotatable shaft, wherein said rotatable shaft is provided at the position of the seal, and
- wherein the seal takes a dual form such that the seal comprises two opposite flexible, elongate expandable bodies which are supported by two elongate, form-retaining holders which are placed at a mutual distance such that strengthened elongate edges of the flexible, elongate expandable bodies connect to each other in an expanded state and wherein the product holder is provided with at least two guide elements for limiting the resistance with which the rotatable shaft can be moved along the seal, each of the guide elements abutting against one of the opposite elongate edges.
A sawing machine for separating electronic components, comprising:

- a product holder displaceable over an upper part of the saw-blade,
- wherein the housing is provided on an upper side with a slot for admitting at least the part of the product holder holding the electronic components into the housing in displaceable manner, wherein the slot is closable by a seal, the seal comprising:
- an elongate form-retaining holder,
- a flexible, elongate expandable body connected to the form-retaining holder and sealing a space medium-tightly,
- a pressure source fluidly coupled to the elongate expandable body, and
- wherein the elongate expandable body is provided with a strengthened elongate edge which is spaced from the form-retaining holder,
- wherein the seal takes a dual form such that the seal comprises two opposite flexible, elongate expandable bodies which are supported by two elongate, form-retaining holders which are placed at a mutual distance such that the strengthened elongate edges of the flexible, elongate expandable bodies connect to each other in an expanded state, and
- wherein the product holder is provided with at least two guide elements for limiting the resistance with which a rotatable shaft can be moved along the seal, each of the guide elements abutting against one of the opposite elongate edges.
