DISPOSITIF DE DEROULEMENT AUTO-AJUSTABLE D'UN FILM PLASTIQUE
La présente invention a pour objet un dispositif de déroulement d'un film ou bande de matière plastique destiné en particulier, mais non exclusivement, aux films déroulés à partir de robots de pose de composants électroniques. SELF-ADJUSTING DEVICE FOR A PLASTIC FILM
The present invention relates to a device for unwinding a plastic film or strip intended in particular, but not exclusively, for films unwound from robots for installing electronic components.
On sait que, pour monter rapidement des composants sur une carte, il est connu de faire appel à un robot qui prélève un composant, disposé dans une bande distributrice protégée par un film plastique protecteur, et le transporte à l'endroit approprié d'une carte. Le film à une épaisseur allant de 0,05 à 0,15 mm. Le pas de déroulement du film dans ce type de machine est compris pratiquement entre quatre et vingt quatre millimètres. La force de décollage du film protecteur est variable. We know that, to quickly mount components on a card, it is known to call on a robot which takes a component, placed in a dispensing strip protected by a protective plastic film, and transports it to the appropriate place of a menu. The film has a thickness ranging from 0.05 to 0.15 mm. The pitch of unwinding of the film in this type of machine is practically between four and twenty four millimeters. The release force of the protective film is variable.
La présente invention concerne le film après prélèvement du composant. The present invention relates to the film after removal of the component.
Il convient en effet d'évacuer le film hors de la machine, de le stocker et enfin de le jeter. It is indeed advisable to evacuate the film out of the machine, to store it and finally to throw it.
Traditionnellement, le film est enroulé autour d'un mandrin d'une bobine entraînée en rotation. Si la bobine tourne à vitesse constante, le mouvement d'enroulement du film est irrégulier en fonction du degré du remplissage de la bobine. Par suite, la traction qui lui est appliquée est variable et l'on observe, soit de nombreuses casses de film, soit un manque d'entraînement du film protecteur car la force de collage est trop importante et le mandrin trop lourd, ce qui conduit dans les deux cas à un arrêt de la machine. Traditionally, the film is wound around a mandrel of a spool driven in rotation. If the reel rotates at constant speed, the film winding movement is irregular depending on the degree of filling of the reel. As a result, the traction applied to it is variable and we observe either numerous film breaks or a lack of training of the protective film because the bonding force is too great and the mandrel too heavy, which leads in both cases when the machine stops.
Il a déjà été proposé, en vue d'y remédier à cet inconvénient de faire passer le film entre deux roues moletées dont les périphéries viennent en contact, puis de les stocker derrière les roues dans un compartiment approprié. It has already been proposed, in order to remedy this drawback, to pass the film between two knurled wheels whose peripheries come into contact, then to store them behind the wheels in an appropriate compartment.
Le film a tendance de s'enrouler autour des roues moletées, entraînant le besoin un guidage derrière le système. De plus, ce système, figée, nécessite un entraînement particulier réalisé à l'aide d'un moteur a courant continu, ce qui est très coûteux. The film tends to wrap around the knurled wheels, causing the need for guidance behind the system. In addition, this system, frozen, requires a special drive carried out using a DC motor, which is very expensive.
Il a déjà été proposé également de faire passer le film entre deux roues moletées dont les périphéries viennent en contact, animés d'un mouvement alternatif, mais la variation de l'épaisseur du film entraîne un écrasement trop important du film entre les pignons, ce qui bloque le mouvement alternatif et donc le système. It has also already been proposed to pass the film between two knurled wheels whose peripheries come into contact, driven by a reciprocating movement, but the variation in the thickness of the film causes the film to be crushed too much between the pinions, which blocks the reciprocating movement and therefore the system.
La présente invention a pour objet de pallier les inconvénients des systèmes connus et de proposer un système, simple, fiable et universel aux différents films à dérouler. The object of the present invention is to overcome the drawbacks of known systems and to propose a simple, reliable and universal system for the various films to be unrolled.
Selon l'invention, le dispositif de déroulement d'un film plastique notamment de composants électroniques est caractérisé par le passage du film entre deux pignons à accouplement non figé, dont le premier pignon est entraîné en rotation, et dont le second repose sur le premier par la force de deux ressorts, ressorts dont la course permets également au pignons de ne plus être en contact. According to the invention, the device for unwinding a plastic film, in particular electronic components, is characterized by the passage of the film between two pinions with non-fixed coupling, the first pinion of which is rotated, and the second of which rests on the first. by the force of two springs, springs whose stroke also allows the pinions to no longer be in contact.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
La course des deux ressorts d'accouplement des deux pignons permet le plaquage du film d'épaisseur différente contre les dents des pignons tout en permettant le patinage des pignons à la fin du pas prévu du déroulement du film. The stroke of the two coupling springs of the two pinions allows the film of different thickness to be pressed against the teeth of the pinions while allowing the pinions to slip at the end of the planned step of the unwinding of the film.
Le pignon du dispositif est de plus petit diamètre que celui du mandrin originel de la machine qui l'entraîne via une courroie , ce qui augmente l'accélération du pignon du dispositif et donc la force initiale d'entraînement afin de pallier à la variation de poids du film à entraîner. Ainsi, par un système de deux pignons à accouplement non figé, un film d'épaisseur variable et de pas variable est déroulé régulièrement. The pinion of the device is of smaller diameter than that of the original mandrel of the machine which drives it via a belt, which increases the acceleration of the pinion of the device and therefore the initial driving force in order to compensate for the variation of weight of the film to be driven. Thus, by a system of two pinions with non-fixed coupling, a film of variable thickness and variable pitch is unwound regularly.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard des figures 1,2, 3 et 4 annexées qui représentent des éléments du déroulement du film selon l'invention. Other characteristics and advantages of the invention will emerge during the description which follows of a particular embodiment, given solely by way of nonlimiting example, with reference to the appended figures 1,2, 3 and 4 which represent elements of the unfolding of the film according to the invention.
Sur la figure 1, on distingue dans la partie supérieure droite une pièce A existante sur la machine. Elle est articulée autour d'un axe B. Cette pièce, destinée à servir originellement de mandrin sur lequel s'enroule le film, est utilisée selon l'invention pour entraîner par la courroie 4 le mécanisme à pignons monté sur la pièce C ( figure 1 partie supérieure gauche, figure 3), mécanisme composé plus explicitement selon la figure 2 par le pignon 1, le pignon 2, les ressorts 3 et 5 qui maintiennent en entraînement les pignons 1 et 2. Le film D à entraîner se situe entre le pignon 1 et le pignon 2 maintenus en engrenage par les ressorts 3 et 5. In Figure 1, there is in the upper right part a part A existing on the machine. It is articulated around an axis B. This part, originally intended to serve as a mandrel on which the film is wound, is used according to the invention to drive by the belt 4 the pinion mechanism mounted on the part C (figure 1 upper left part, FIG. 3), mechanism composed more explicitly according to FIG. 2 by the pinion 1, the pinion 2, the springs 3 and 5 which hold the pinions 1 and 2 in training. The film D to be driven is located between the pinion 1 and pinion 2 held in gear by springs 3 and 5.
La variation de l'épaisseur du film est assurée en entraînement par l'élasticité des ressorts 3 et 5 qui plaquent les deux pignons 1 et 2 sur la surface du film. Le diamètre du pignon 2, entraîné par la courroie 4, étant inférieur au diamètre de la pièce A qui l'entraîne, le déroulement du film D est multiplié. The variation of the thickness of the film is ensured in drive by the elasticity of the springs 3 and 5 which press the two pinions 1 and 2 on the surface of the film. The diameter of the pinion 2, driven by the belt 4, being less than the diameter of the part A which drives it, the unwinding of the film D is multiplied.
Quand la longueur de déroulement prévue est atteinte, le couple résistant du film D débraye le pignon 1 par l'élasticité des ressorts 3 et 5 qui remontent le pignon 1 de l'épaisseur du film afin que le pignon 2 patine sur le film. When the planned unwinding length is reached, the resistive torque of the film D disengages the pinion 1 by the elasticity of the springs 3 and 5 which raise the pinion 1 the thickness of the film so that the pinion 2 slips on the film.
Sur la figure 4, on distingue les différents cas d'entraînement du film D. Sur la figure 4a, le film D est fin et épouse les forme des dents du pignon 2, le film est entraîné. Sur la figure 4b, le film D est plus épais mais il reste entraîné par l'existence du plaquage du pignon 1 sur le pignon 2. Sur la figure 4c, le couple résistant du film D fait que le pignon 1 n'est plus en contact avec le pignon 2 provoquant un patinage du pignon 2 sur le film D. In FIG. 4, a distinction is made between the different drive cases for the film D. In FIG. 4a, the film D is thin and follows the shape of the teeth of the pinion 2, the film is driven. In FIG. 4b, the film D is thicker but it remains entrained by the existence of the pinion 1 plating on the pinion 2. In FIG. 4c, the resistive torque of the film D means that the pinion 1 is no longer in contact with the pinion 2 causing the pinion 2 to slip on the film D.
Le dispositif selon l'invention est réglable et peut s'adapter dans le temps aux différentes exigences des constructeurs. Il peut être adapté à tout système mécanique. The device according to the invention is adjustable and can adapt over time to the different requirements of manufacturers. It can be adapted to any mechanical system.
Il va de soi que de nombreuses variantes peuvent être apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de l'invention. It goes without saying that many variants can be made, in particular by substitution of equivalent technical means, without departing from the scope of the invention.
