Abstract
Abstract A parts mounting machine for easily changing the type or number of parts being used within includes a work piece positioning device for positioning a work piece on a movable table thereon, and a plurality of part handling units which can be fixed to and detached from the work piece positioning device. Each of the parts handling units comprises mounting head means for holding a part and transferring it to the work piece, and transfer means for removing the part from a container and transferring the part to the mounting head means. Also contained in each handling unit is a controller for regulating the operation of the mounting head and transfer means. A main controller selectively controls the branch control means so that the parts handling units cooperate with the work piece positioning device as required by a user.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
121 words
A parts mounting machine comprising: a work piece positioning device having a movable table for positioning a work piece at a predetermined location thereon: a plurality of parts handling units detachable fixed to the work piece positioning device, each unit further comprising: mounting head means fixedly attached to the unit, for holding a part and for mounting the part onto the work piece; transfer means fixedly attached to the unit, for transferring the part from a container of parts to the mounting head means; and branch control means, for controlling the mounting head means and transfer means; and a main controller, for selectively controlling the branch control means so that the parts handling units cooperate with the work piece positioning device.
Claim 2
Dependent Claim
121 words
A parts mounting machine comprising: a work piece positioning device having a movable table for positioning a work piece at a predetermined location thereon: a plurality of parts handling units detachable fixed to the work piece positioning device, each unit further comprising: mounting head means fixedly attached to the unit, for holding a part and for mounting the part onto the work piece; transfer means fixedly attached to the unit, for transferring the part from a container of parts to the mounting head means; and branch control means, for controlling the mounting head means and transfer means; and a main controller, for selectively controlling the branch control means so that the parts handling units cooperate with the work piece positioning device.
Claim 3
Dependent Claim
38 words
A parts mounting machine according to claim 1, wherein each of the mounting head means includes a head whose one end surface is a datum point in relation to the mounted part and the work piece positioning device.
Claim 4
Dependent Claim
20 words
A parts mounting machine according to claim 1, wherein the branch controllers are fixed on the respective parts handing units.
Claim 5
Dependent Claim
18 words
A parts mounting machine according to claim 1, wherein the work piece positioning device has an indexing table.
Claim 6
Dependent Claim
33 words
A parts mounting machine according to claim 1, wherein the work piece positioning device has at least three positioning pins against which at least two datum sides of the work piece are pressed.
Claim 7
Dependent Claim
36 words
A parts mounting machine according to claim 1, wherein the branch control means outputs data showing a function performed by the respective parts handling unit to the main controller, and the main controller memorizes said data.
Claim 8
Dependent Claim
140 words
A parts mounting machine according to claim 6, wherein the main controller compares said data with a first mounting operation instruction signal inputted to the main controller, selects one of the parts handling units suitable for mounting a first kind of parts, and generates a mounting operation starting signal indicative thereof to the selected parts handling unit. A parts mounting machine according to claim 6, wherein the selected parts handling unit generates a compensated-positioning data signal which is calculated by the respective branch controller in accordance with distances in the X and Y directions between the datum point of the selected parts handling unit and the datum point of the starting signal including distance data between a datum side of the work piece and a position where a datum point of the part should be mounted on the work piece.
Claim 9
Dependent Claim
86 words
A parts mounting machine according to claim 6, wherein the selected parts-handling-unit outputs a compensated-positioning data which is calculated by the branch controller in accordance with distances in the X and Y directions between the datum point of the selected parts-handling-unit and the datum point of the handled part on the basis of the mounting operation starting signal including distance data between a datum side of the work piece and a position where a datum point of the part should be mounted on the work piece.
Claim 10
Dependent Claim
90 words
A parts mounting machine according to claim 8, wherein the work piece positioning device positions the table at an initialized position and causes the table to move a distance determined by the main controller, said main controller then measures a distance between the datum point of the table and the datum point of the parts handling unit and calculates and memorizes a sum total of the moved distance and the measured distance as an actual distance between the datum point of the parts handling unit and a table reference point.
Claim 11
Dependent Claim
96 words
A parts mounting machine according to claim 9, wherein the main controller calculates a required distance between the table reference point and the datum point of the table in accordance with the distance between the datum point of the table and the datum side of the work piece, and the distance between the datum point of the parts handling unit and the table reference point on the basis of the compensated-positioning data so that a positional relation between the datum side of the work piece and the datum point of the handled part is correctly controlled.
Claim 12
Dependent Claim
121 words
A parts mounting machine comprising: a work piece positioning device having a movable table for positioning a work piece at a predetermined location thereon; a parts handling unit detachably fixed to the work piece positioning device, further comprising: mounting head means fixedly attached to the unit, for holding a part and for mounting the part onto the work piece; transfer means fixedly attached to the unit, for transferring the part from a container of parts to the mounting head means and the transfer means; and branch control means, for controlling the mounting head means and the transfer means; and a main controller, for controlling the branch control means so that the part handling unit cooperates with the work piece positioning device.
Claim 13
Dependent Claim
121 words
A parts mounting machine comprising: a work piece positioning device having a movable table for positioning a work piece at a predetermined location thereon; a parts handling unit detachably fixed to the work piece positioning device, further comprising: mounting head means fixedly attached to the unit, for holding a part and for mounting the part onto the work piece; transfer means fixedly attached to the unit, for transferring the part from a container of parts to the mounting head means and the transfer means; and branch control means, for controlling the mounting head means and the transfer means; and a main controller, for controlling the branch control means so that the part handling unit cooperates with the work piece positioning device.
