Definitions
- the present invention relates to a device for dispensing components of plastic or metal clip type intended in particular for the assembly of parts.
- Such components are intended to be fitted by snapping onto parts which, subsequently, will be stapled onto supports.
- these staples include a head configured to snap onto the work, and a foot configured to snap onto the holder.
- such clips can be used when mounting plastic parts inside or outside a motor vehicle.
- staple dispensing devices generally comprise a vibrating bowl in which the staples are stored in bulk and guide rails for conveying the staples from the vibrating bowl to the workstations of an assembly line.
- These known distribution devices however have the drawback of being complex to implement.
- jamming problems frequently occur in the vibratory bowl and guide rails due to poor positioning of the clips. These blockages therefore generate production stoppages which greatly limit the feed rates of the staples.
- a dispensing device which is based on the use of a vibrating table onto which staple-type components are poured and which, due to the vibration of the table, are positioned in a position. predetermined stable.
- An optical device, of the camera type, placed directly above the table makes it possible to detect well-positioned components. This information is then transmitted to a control unit which controls the movement of the robot's gripping arm so as to pick up only well-positioned components and then transfer them to a downstream processing area.
- this device has the drawback of not being suitable for three-dimensional components whose external shape does not allow a stable position to be reached on the vibrating table.
- an aim of the invention is to provide a device for dispensing components of the clip type which does not have the drawbacks of the aforementioned prior art.
- the invention relates to a device for distributing staple-type components intended in particular for the assembly of parts, comprising:
- a temporary storage tray for components extracted from the main store configured to temporarily store the components waiting to be transferred out of the device, said tray being mounted in reciprocating translation in at least one longitudinal direction so as to be able to stir said temporarily stored components and promote their positioning inside said plate according to at least one predetermined stable position linked to their shape,
- an optical detection system configured to detect, among the components temporarily stored inside the temporary storage tray, those having said predetermined stable position
- a transfer system configured to transfer, individually or in groups, the components having said predetermined stable position to a downstream processing zone located outside the device
- an electronic control unit in electronic connection with the optical detection system and the transfer system, said unit being configured to control the transfer system in particular as a function of detection signals received from the optical detection system,
- the temporary storage tray is provided with a series of individual housings, each of said housings being configured to receive a single component according to said predetermined stable position.
- the invention makes it possible to promote the stable positioning of the components at the level of the temporary storage tray due to the presence of individual housings in which the components can be housed in a stable position of equilibrium, thus greatly limiting the risk of damage. subsequent tilting of the components to an unstable position due to the agitation induced by the tray. Once in their stable equilibrium position, the components can be easily picked up by the transfer system and then transferred to a downstream processing zone.
- the device of the invention may include one or more of the following characteristics, taken individually or in combination: -
- Each of the individual housings forms a through opening inside the temporary storage tray, said opening being configured to allow the passage of a first part of the components and prevent the passage of a second part of the components.
- the geometry of the opening is adapted to that of the component considered.
- Each through opening has a circular section, the geometry of this opening being adapted to that of the component considered.
- the individual housings are distributed on the temporary storage tray according to the geometry of the component.
- the optical detection system includes an optical camera oriented to view the temporary storage tray from above and processing software image capable of receiving and analyzing the images taken by the optical camera so as to detect the components stored on the temporary storage tray having the predetermined stable position.
- the transfer system consists of a robot with an articulated arm and having at least one gripping finger configured to individually grip the components stored on the temporary storage tray having the predetermined stable position.
- FIG. 1 is a schematic view of a component dispensing device according to the invention.
- FIG. la is a perspective view of a possible variant of the temporary storage tray usable in the device shown in Figure 1.
- FIG. 2 is a perspective view of another possible variant of temporary storage tray usable in the device shown in Figure 1.
- FIG. 3 is a top view of the tray shown in Figure 2, in which a number of components have been stored.
- FIG. 4 is a perspective view of a clip intended to supply the device of the invention.
- a dispensing device 1 according to a first configuration of the invention.
- This device 1 comprises in particular a main store 110 for receiving components A having various shapes in bulk.
- a conveyor table 120 disposed under the main store 110 and supporting a temporary storage tray 130 can move in a longitudinal direction D so as to move the tray 130 away from or closer to the main store 110.
- the components A are then arranged randomly on the surface of the plate 130, whether at their level. positioning in the plane defined by the plate 130, but also at the level of their orientation in space.
- the plate 130 is then moved in a series of reciprocating movements back and forth, parallel to the direction D, or transversely or else along a Z axis around a central position. These reciprocating movements cause stirring of the components A which modify their orientation and their positioning on the plate 130.
- some of the components A could for example tilt d. 'an unstable position, in which they are standing on the tray 130, to a stable position, in which they are lying on the tray 130.
- the device 100 further promotes this passage from an unstable position to a stable position by providing the tray 130 of a series of individual housings 131, as shown in FIG.
- Each of the housings 131 is configured to at least partially contain a single component A.
- each of the housings 131 forms a cavity on the upper surface of the plate 130, said cavities having an L-shape substantially complementary to that of the components A.
- the housings 131 are distributed in a regularly spaced manner on the surface of the plate and advantageously have a distribution in row and in column.
- the temporary storage tray 130 will make it possible to receive in the housings 131 the components A which, due to the agitation of the tray, have been moved so as to be in the lying position and correctly positioned to be received at the interior of the housings 131.
- the components A thus arranged in the housings 131 will retain a fixed position relative to the plate 130.
- An optical detection device 140 of the camera type for example, positioned above the plate 130 will allow viewing the whole of the plate 130 and the output signal delivered by said optical detection device 140 can be analyzed by digital processing software so as to detect the components A having a predetermined position.
- the optical detection device 140 will be able to detect at any time the components A which are positioned inside the housings 131.
- the optical detection device 140 transmits the information corresponding to a control unit 150 which is in electronic communication with a transfer device 160, of the robot type for example, so as to indicate to it that it can take individually, thanks to an input means such as a finger input 161, for example, or even a clamp, or in a grouped manner the components A having the predetermined position.
- the transfer apparatus 160 is then responsible for the transfer of said components A to a downstream processing zone 170 located outside the distribution device 100.
- the temporary storage tray 130 is provided with a series of through openings 131 of circular shape, the openings 131 being distributed in an alignment of rows and columns.
- Each opening 131 is able to contain a clip A having characteristics similar to that shown in FIG. 4, namely a shape in two parts separated by a circular central flange 16.
- a first part 12, in the form of a shell corresponds to the foot of the clip A and is intended to be inserted into a metal sheet of a vehicle frame.
- a second part 14, in the form of a disc corresponds to the head of the clip A and is intended to be inserted into a plastic part covering the frame.
- the collar 16 is separated from the head 14 by a groove 18.
- the groove 18 will be dimensioned so as to allow the engagement of the plastic part intended to be fixed to the frame.
- Each opening 131 thus has a diameter configured to allow the introduction of the foot and / or the head of the staples A but to prevent the passage of the collar 16.
- a first position PI will correspond to a first preferred stable position for the staple A.
- the staple A is positioned such that its foot 12 is disposed completely inside the plate 130, the staple A resting on the upper surface of the plate 130 at the level of its flange 16.
- the head 14 of the clip A protrudes from the plate 130 and can be easily grasped by the gripping finger 161 of the robot 160.
- a second position P2 will correspond to a second preferred stable position for clip A.
- clip A is positioned so that its head 14 is disposed completely inside the plate 130, the clip A resting on the upper surface of the plate 130 at the level of its flange 16.
- the foot 12 of the clip A protrudes from the plate 130 and can be easily grasped by the gripping finger 161 of the robot 160.
- a third position P3 will correspond to an unstable position for the staple A.
- the staple A is positioned such that its collar 16 is partially engaged inside an opening 131 by the edge, the clip A resting on the upper surface of the plate 130 at the level of its foot 12 and / or of its head 14. In this position, the clip A cannot not easily grasped by the gripping finger 161 of the robot 160.
