Definitions
- the present invention relates to a method allowing the adjustment of the component holder supports of a barrel of conveyor of electronic components, as well as a barrel allowing the execution of the method.
- the electronic components During their manufacture, their packaging or before their integration on a printed circuit, the electronic components generally undergo a succession of operations, for example electrical tests, along a production chain often entirely automated. The electronic components are thus transferred from one processing station to another by a conveyor, which may for example be linear or circular.
- a barrel is the central element of a circular conveyor, around which are defined several locations of regularly spaced treatment stations. Each of these locations is generally occupied by a processing station performing one or more operations on the electronic components presented to it. In some cases, a treatment center can occupy several locations. All the processing stations arranged around the barrel thus form a cycle of successive operations, for example electrical or mechanical tests, conditioning operations, etc., to which the electronic components conveyed onto the barrel are subjected.
- the first cycle processing station is generally an entry station, the role of which essentially consists in bringing the electronic components, from a tank or from another conveyor, onto the barrel.
- the cycle can include one or more output stations, thus making it possible to output the components at different stages of the cycle, for example as a function of characteristics measured on a previous test station.
- the barrel 9 is equipped with support for component holders, generally sockets 4, into which are inserted component holders 5 serving to pick up or receive the electronic components from the various processing stations, to maintain them during the movement of the barrel and, if necessary, to present them to the following processing station.
- the sockets 4 are regularly distributed over the barrel 9, on a circle close to its periphery, according to an arrangement corresponding to that of the locations defined around the barrel 9. During a 360 ° rotation around its center, the barrel
- each socket 4 finds itself facing a location for a treatment station.
- the barrel 9 and the treatment stations are generally integral with the same base plate 1, thus guaranteeing the maintenance of their relative positions.
- Barrel 9 is often mounted directly on a rotary motor
- the barrel 9 is rotated around its center by the motor 10 in short and rapid rotational movements followed by stopping moments at each step.
- each component carrier 5 inserted in their supports 4 pick up or receive the component located on the processing station facing them.
- the position of the barrel is then indexed by one step.
- the components removed by the component holders 5 are held by the latter on the barrel 9.
- each component holder 5 is faced with the following location, which is generally equipped with the next cycle processing station.
- the component is then made available to the processing station which performs the operation for which it is designed.
- the barrel is generally immobilized. The steps described above are repeated, the conveyor thus successively transferring each component from one treatment station to the next, until all the components to be treated have been subjected to a cycle of operations.
- the component holders 5 of the barrel comprise a nozzle 51 picking up and holding the electronic components by air vacuum.
- Other systems are however possible, for example mechanical gripping systems, for example pliers, or receptacles on which the components are deposited by each processing station and from which they are removed by the following processing station.
- they are installed on the barrel 9 after the complete manufacture of the latter, generally on component holder supports, for example sockets 4, themselves fixed to the barrel 9 in profiles 91 adapted.
- the sockets are driven into holes machined at the periphery of the barrel.
- the component holders 5 have an elongated cylindrical part 50 which is inserted into the corresponding socket 4.
- a system of ball bearings 41 is slid between the socket 4 and the component holder 5. The position of the component holder 5 in the axis of the socket 4 is adjusted so that the nozzle is at the desired height. A ring 7 is then slid around the cylindrical part 50 of the component holder 5 until it comes into abutment against the bush 4.
- the ring 7 has a rod 71 which is inserted in an auxiliary hole 92, thus avoiding, after tightening, the ring 7 on the cylindrical part 50 of the component holder 5, any undesirable rotation of the component holder 5 in the socket 4.
- the socket 4, the component holder 5, its locking elements 7, 71 and their interaction with the profiles of barrel 91 and 92 are detailed above by way of example. Conveyors of electronic components can use a wide variety of mechanisms to attach the component holders to the barrel 9.
- the profiles intended to receive the component holder supports are machined during the manufacture of the barrel.
- the accuracy of their location and their dimensions will therefore largely depend on the accuracy, in the finished system, of the alignment of the support, and consequently of the component holder, with the locations of the treatment stations defined around the barrel.
- the assembly of the system generally begins by centering and fixing the barrel to the engine, itself previously centered on the base plate, relative to the locations defined around it. The treatment stations are then fixed on the base plate, in a position as precise as possible relative to the position of the barrel.
- Such a system has important limitations with regard to mounting accuracy. Indeed, a slight error in the centering of the barrel can lead to significant inaccuracies in the positioning of the sockets, and therefore of the component holders, relative to the treatment stations.
- the known methods of error calculation teach us in particular that the total error on the position of the sockets with respect to the locations of the processing stations is equal to the addition of the errors at each stage of manufacture or assembly, namely the error on the centering and the dimensions of the profiles intended to receive the component holder supports during the manufacture of the barrel, the error on the centering of the motor on the base plate, the error on the centering of the barrel on the motor , the error on the dimensions of the component holder support and the error on its positioning on the profile intended to receive it.
- such a system does not allow the correction of an error on the location or the dimensions of a single profile, occurring for example during the manufacture of the barrel.
- One of the aims of the present invention is therefore to propose an adjustment method making it possible to obtain an increase significant in the alignment accuracy of the barrel component holders with respect to the treatment stations.
- this object is achieved by a method allowing the individual adjustment of each component holder support of the barrel, preferably after the barrel is mounted on the base plate.
- this object is achieved by a method for adjusting the position of the component holder supports of a barrel, said method comprising:
- Figure 1 detailed previously illustrates a circular conveying system comprising a barrel.
- FIG. 2 detailed previously illustrates an example of a component holder.
- Figure 3 shows a barrel and its position relative to the calibration station used in a preferred version of the method.
- FIG. 4 shows the calibration station used in a preferred version of the invention and its interaction with the component holder support to be adjusted.
- FIG. 5 shows a portion of the periphery of a barrel suitable for the execution of another preferred variant of the invention.
- Figure 6 shows a section through one of the fingers of Figure 5.
- the present invention is applied to a barrel 9, the component holder supports of which are sockets 4 fixed in holes 91 distributed regularly over a circle close to the periphery of the barrel 9.
- the barrel 9 is fixed in rotation on a base plate 1. Before its complete fixing, its position is adjusted so that it is as centered as possible relative to at the locations provided on the base plate for treatment stations. At least one of these locations is temporarily occupied by a calibration station 2 defining a reference position for adjusting the position of the sockets 4.
- the calibration station 2 used for the execution of this preferred version of the inventive method is maintained by its base, preferably screwed, on the base plate 1. It comprises a calibrated rod 20 of a diameter close to the inside diameter of the sockets 4.
- the calibrated rod 20 is held upwards by the action of a spring 21, in the axis along which the sockets 4 should be oriented, generally vertically with respect to the base plate 1.
- the reference rod 20 can be pulled down using a pin 22.
- the barrel 9 is oriented so that a first hole 91 is positioned above the reference rod 20, while the latter is held down.
- the reference rod 20 is raised in the hole 91 and a bush 4 is slid along the reference rod 20 inside the hole 91.
- On the reference rod is fixed a ring similar to the rings 7 used to block the component holder 5, thus making it possible to precisely determine the position of the socket 4 to be adjusted on the axis of the reference rod.
- the diameter of the hole 91 is substantially larger than the outside diameter of the sleeve 4 in order to give the latter a certain freedom thus allowing the adjustment of its position.
- the rotation of the barrel 9 can be slightly corrected in order to center as much as possible the hole 91 around the bush 4 held by the reference rod 20.
- the position of the barrel after correction is preferably recorded by the engine control system as position of reference of the indexing system.
- a hardening material for example glue, putty, resin, etc., is then poured into the space between the hole 91 and the sleeve 4 in order, by hardening, to fix the sleeve 4 to the barrel 9.
- the reference rod 20 is again pulled down using the pin 22.
- the motor 10 is activated in order to rotate the barrel 9 a certain number of steps, until a new hole 91 is positioned above the reference rod 20.
- the reference rod 20 is raised and inserted into the hole 91.
- a socket 4 is slid along the reference rod 20 into the hole 91 and liquid hardening material is poured into the space between the hole 91 and the sleeve 4.
- the reference rod 20 is again removed from the socket 4 to allow movement of the barrel 9 until a new hole 91 is presented opposite the calibration station 2.
- the position of each socket 4 is thus individually adjusted with respect to a reference position corresponding to the future position of the receiving and / or output elements of the processing stations which will be installed around the barrel 9
- the possible error on the position of the socket 4 is thus only determined by the possible error when adjusting this position by report to the calibration station 2.
- Such a method thus makes it possible to compensate for, or even totally correct, errors or inaccuracies which have occurred during the preceding steps, for example during centering of the barrel or during the machining of the holes 91 in the barrel 9, etc.
- Each processing station installed around the barrel 9 is then individually precisely positioned so as to align its components receiving and / or output elements with the position of the component carriers 5.
- the alignment accuracy between the component holders 5 and the treatment stations thus only depends on the precision of the adjustment of the sockets 4 and on the precision of the alignment of each treatment station.
- the inventive method is applied to a barrel 9, illustrated by FIGS. 5 and 6, comprising adjustable fingers 8 distributed regularly over its periphery and intended to receive the support for component carriers.
- the component holder supports, in this case the sockets 4, are driven into holes 81, without the possibility of adjusting their position relative to the adjustable finger 8.
- each adjustable finger 8 has only one socket 4.
- the adjustable finger 8 is fixed to the barrel 9 by a screw 86.
- Pins 95 are slid through orifices provided for this purpose on the barrel 9 and one of their ends is slid in a guide 84 formed on the face of the adjustable finger 8 oriented against the barrel 9, thus maintaining the latter in a substantially radial position relative to the center of the barrel 9.
- An additional pin 96 is driven into a hole passing through the barrel 9 and serves to support the radial adjustment screw 87, of which the function is described later.
- the adjustable finger 8 has a notch 850 whose shape defines a rigid profile 83 and two flexible strips 85. The position of the rigid profile is fixed relative to the part of the adjustable finger 8 fixed to the barrel 9.
- the flexible strips 85 allow, on the other hand the movement of the end of the adjustable finger 8 on which the socket 4 with respect to the rigid part 83, under the action of the tangential adjustment screws 88.
- the barrel 9 equipped with its adjustable fingers 8 is preferably fixed in rotation on the motor 10 previously attached to the base plate 1 and is centered on the latter relative to the locations provided for the positions of treatment.
- a calibration station is installed at one of the processing station locations.
- the calibration station is preferably an optical system comprising a camera aiming precisely in the axis on which the sockets 4 must be centered.
- the signal from the camera is displayed on a control screen and is superimposed on a target precisely determining the center of the image.
- the superimposition, on the control screen, of the image of the socket 4 filmed by the camera and of the test pattern thus makes it possible to determine the alignment of the socket 4 relative to the reference axis.
- the calibration station comprises two mechanical comparators oriented perpendicularly to each other and perpendicular to the reference axis on which the sleeve 4 must be centered.
- the comparators are brought, in a reference position, into contact for example with the external surface of the socket 4 to be adjusted or with the external surface of a calibrated pin inserted in the socket 4.
- the deviations of the position of this surface the along the axes of the comparators with respect to a reference position can thus be measured with precision, making it possible to control the perfect fit of the sleeve 4 on the reference axis.
- the position of the sleeve 4 in the direction tangent to the barrel 9 is adjusted by means of the tangential adjustment screws 88 which press on the two opposite faces of the rigid profile 83 at the center of the cutout 850.
- the tangential adjustment screws 88 which press on the two opposite faces of the rigid profile 83 at the center of the cutout 850.
- the motor 10 is activated in order to rotate the barrel 9 by a certain number of steps, until bringing a new adjustable finger 8 to adjust in front of the calibration station. The adjustment steps described above are then repeated until all the adjustable fingers 8 of the barrel 9 have been adjusted.
- the component holders 5 can be fixed on the barrel 9, for example according to the principle described above and illustrated by FIGS. 1 and 2.
- the position of each socket 4 is thus individually adjusted with respect to a reference position corresponding to the future position of the receiving and / or output elements of the processing stations which will be installed around the barrel 9
- the possible error on the position of the socket 4 is thus only determined by the possible error when adjusting this position by report to the calibration station 2.
- Such a method thus makes it possible to compensate for, or even totally correct, errors or inaccuracies which have occurred during the preceding steps, for example during centering of the barrel or during the machining of the holes 81 in the adjustable fingers 8 , etc.
- the means for adjusting the adjustable finger 8 described above are designed for adjusting the position of the sleeve 4 along two axes in a horizontal plane relative to the base plate 1, those skilled in the art will understand that it is perfectly conceivable to complete or modify these adjustment means in order, for example, to also be able to adjust the position of the sleeve in a vertical plane or along any other axis.
- Each treatment station installed around the barrel is then individually positioned precisely so as to align its components receiving and / or output elements with the position of the component holders.
- the precision of the alignment between the component holders and the treatment stations depends only on the precision of the adjustment of the sockets and the precision of the alignment of each treatment station.
- the inventive method makes it possible to compensate, by means of the individual adjustment of each component holder support with respect to a single reference position, of compensate for errors or inaccuracies that occurred in the previous stages of manufacturing or assembling the system, such as, for example, inaccuracies during the machining of the profiles intended to accommodate the component holder supports, errors in centering the barrel in relation to the locations provided for treatment stations, etc.
- the adjustment of each component holder support is done individually
- the skilled person will understand that it is also possible to implement the inventive method in a way to be able to simultaneously adjust the position of several component holder supports, for example by the simultaneous use of several calibration stations, by the use of calibration stations comprising several reference positions corresponding to the positions of several sockets to be adjusted , contiguous or not, etc. If it allows a reduction in the time necessary for the adjustment of all the component holder supports of the barrel, this variant of the inventive method nevertheless presents more possibilities of imprecision in the adjustment, in particular by possible errors. in the relative positions of the different reference positions.
