Definitions

  • the invention relates to a machine for depositing glue on screws and its associated method.
  • the object of the invention is to automate the process of depositing glue on screws, in particular on screws of small sizes. It is more particularly intended for the fields of eyewear, jewelery, and micromechanics but could be used in other fields.
  • a screw has a longer or shorter rod and a head located on one end of the rod.
  • the head has a diameter wider than the stem.
  • the rod comprises along its entire length a lateral surface provided with a thread with a thread of male screw intended to be housed in a hole also provided on its inner surface with a screw thread with complementary female thread.
  • the rod also has at the opposite end of the head of the screw, a lower surface corresponding to the section of the rod.
  • a small screw is characterized by the fact that it is hardly possible to hold such a screw between two fingers of a hand.
  • a small screw is essentially characterized by its dimensions.
  • a small screw does not exceed a width of the largest finger of the hand.
  • a small screw used for mounting the frames of a pair of spectacles has a diameter of 1.2 millimeters for the stem on 2.5 millimeters for the head.
  • Such previously glued screws can be obtained by several methods.
  • a craft method The traditional method is the use of a tray containing an adhesive. In this tray, the screws are placed in such a way that only the screw shank is immersed in the glue. Once the rod is covered with glue, the screws are removed from the tray and dried.
  • this artisanal method requires to manually arrange the screws one by one in such a way that only the rod bathes in the liquid. Once glued, the screws must be removed from the tray manually and one by one. Then they are individually dried so that they do not touch each other and do not stick together.
  • This method makes it possible to simultaneously obtain a limited number of glued screws. This method also requires the presence of an operator. Thus, this method is a tedious and unprofitable method from the point of view of the time of realization and from the economic point of view.
  • the screw to be glued is preferably small.
  • the handling of several small screws at a time with the fingers of the operator is thus made difficult to perform.
  • the deposition of the glue preferably only on the stem of the screw is made all the more difficult as the rod is small.
  • the drying of the bonded screw must be done in such a way that the screws can not stick together.
  • simultaneously obtaining a large amount of these small screws glue is difficult to achieve manually.
  • the viscosity of the adhesive is such that the deposition of glue on each side of the screw tends to diffuse so that these two glue deposits meet.
  • gluing in two deposits may lead to an imperfect glue covering on the screw, with a thickness of glue irregularly distributed on a surface of the screw.
  • the invention provides for automating the method of obtaining screws previously glued.
  • the invention consists in a machine for depositing glue such that this machine does not require the intervention of an operator.
  • this machine allows, according to the invention, to deposit glue on a large number of screws at a time, and in particular small screws.
  • the invention comprises a rotating disc bathed at least partially in a tray containing glue. The rotational speed of the disc is such that the glue concentrates at the periphery of the disc. Then the disc, via the glue, is brought into contact with at least one screw to impart a rotational movement and propulsion to the screw fast enough to glue at least the entire periphery of at least a portion of the lateral surface of the rod of each screw in contact with the glue on the disc.
  • glue is the glue distributed on a part of the disk which is directly in contact with the screw.
  • the glue deposited on the screw is microencapsulated epoxy resin type.
  • This glue is microencapsulated in such a way that when the glued screw is screwed inside a corresponding hole, microcapsules crush as and screwing to dump their contents in the thread of the screw and the hole.
  • the microcapsules containing the epoxy resin glue are suspended in another glue.
  • This other glue is liquid and contains a hardener and a dye.
  • the hardener makes it possible to obtain the polymerization of the epoxy resin released by the crushed microcapsules during screwing.
  • the dye makes it possible to visualize the place on the stem where the glue has been deposited.
  • This adhesive with these microcapsules is made in such a way that it allows at least a second or even a third screw screwing operation. Thus, in the case where the screw has been unscrewed to reposition an assembly, or make an adjustment, it is possible to screw this screw again, microcapsules that have not been crushed during a previous screwing can then release their contents. .
  • the figure 1 shows a machine 1 to deposit glue 2 on screws 3 according to the invention.
  • the machine 1 to deposit glue 2 on screws 3 comprises, in the direction of movement of the screw 3, a means 4 for placing on a guide rail 5, at least one screw 3 of small size and a device 6 to deposit the adhesive 2 on at least one screw 3 of small size.
  • a screw 3 has a rod 7 more or less long and a head 8 located on one end of the rod 7.
  • the head 8 has a larger diameter the rod 7.
  • the rod 7 comprises along its entire length a side surface 9 provided with a male thread thread 10 and at the opposite end of the head 8, a lower surface 11 corresponding to a section of the rod 7.
  • the screws 3 are preferably made of stainless steel so that they do not oxidize and they are as light as possible. They can also be made of steel, gold, titanium, platinum or gold-plated stainless steel.
  • Means 4, figure 1 allowing to position the screws 3 in a certain position on the guide rail 5 is preferably a vibrating bowl 4.
  • This vibratory bowl 4 is a hollow container of generally conical shape. It has a base 12 of smaller diameter and a vertex 13 of larger diameter. From the base 12 and inside the bowl 4, a path 14 of helical shape is dug in the wall of the bowl 4 to the top 13 of the bowl 4.
  • the access path 14 has a width that corresponds at least to the size of the head 8 of the screw 3.
  • the vibratory bowl 4 has the property of vibrating so that the screws 3 can be organized in row of onions, the head 8 placed on the path 14 so that the screws can move towards the top 13 of the bowl 4.
  • the bowl 4 is provided with a motor, not shown, for vibrating the bowl 4.
  • the path traveled by the screw is then interrupted at the point where the path 14 opens at the top 13 of the bowl 4.
  • the relay of the path traveled by the screw 3 is provided by the guide rail 5.
  • the interruption of the path of the screw 3 between the top 13 of the bowl 4 and the rail 5 corresponds to a vacuum 15.
  • This vacuum 15 must correspond to a distance such that the screw can not fall from the bowl 4 and the rail 5. It is necessary because the vibration of the bowl 4 is not necessarily synchronous with that of rail 5.
  • the rail 5 has an inlet 16 and an outlet 17.
  • the inlet 16 indirectly follows the path of the screw 3 leaving the path 14 at the top 13 of the bowl 4, via the vacuum 15.
  • the outlet 17 corresponds to the opposite end of the inlet 16 of the rail 5.
  • the rail 5 comprises two blades 18 spaced apart at a spacing 19. This spacing 19 allows the blades 18 to hold each screw 3 at the head 8 while leaving the possibility to screw 3 to move by vibration.
  • the spacing 19 between the two blades 18 is adjustable and depends on the characteristics of the screw 3. For example, it is possible to tighten or move the two blades 18 so that they can adapt to the diameter of the rod 7 of the screw 3 to be glued.
  • the spacing 19 between the two blades 18 can be adjusted, for example, by means of adjusting screws, not shown, located on each of the ends 16 and 17 of the rail 5.
  • the spacing 19 of the two blades 18 s by screwing, for example, each of the adjusting screws at the two ends 16 and 17 of the rail 5.
  • the gap 19 between the two blades 18 can be adjusted by joining each of the adjusting screws to the two ends 16 and 17 to obtain a unique setting. This last adjustment has the advantage of obtaining a spacing 19 of the two blades 18 uniformly along the rail 5.
  • the rail 5 can be inclined towards the outlet 17 of the rail 5.
  • the inlet 16 of the rail 5 is raised relative to the outlet 17.
  • a vibratory source can also be installed near the rail 5.
  • This vibratory source can be a vibrating box 20 installed near the rail 5 so that the vibrating box 20 can transmit its vibration to the rail 5.
  • the rail 5 can thus vibrate in such a way that the screws are arranged one behind the other.
  • the machine 1 to deposit glue comprises a blower system 21 for drying the glue 2.
  • This blower system 21 is disposed near the path of the screw 3, along the rail 5 and after the device 6 according to the invention .
  • This blower 21, by the breath it releases, can also facilitate the movement of the screw 3 glued in the desired direction.
  • this blower 21 may be a pipe provided with holes 22 oriented in one direction, represented by an arrow 23 on the figure 1 , such that the outgoing breath of these holes 22 facilitates the movement of the screw 3 in the desired direction.
  • a tray 24 for harvesting the screws 3 sized and dried.
  • a power supply 25 is installed near this machine 1 to control each of the motors, not shown, of the bowl 4, the vibrating box 20 and the blower 21.
  • the device 6, according to the invention, is located near the blades 18, preferably close to the inlet 16 of the rail 5 and before the blower 21.
  • the machine 1 comprises a device 6 for depositing the adhesive 2 on at least one screw 3 of small size.
  • This device 6 comprises a disc 26 rotated at least partially in a tray 27 containing glue 2.
  • the disc 26 is toughened hard steel and the disc 26 has a periphery 28 sharpened.
  • the disc 26 is fixed to an articulated arm 29.
  • This articulated arm 29 is removable such that the disc 26 can glue in front of or behind the screw 3 relative to a plane defined by the line of advance of the screw 3 on the rail 5 and the position of the screw 3 on the rail 5.
  • the feed line is symbolized by the rail 5 itself.
  • the articulated arm 29 has a hinge 30, a first part 31 and a second part 32 on either side of the hinge 30.
  • the first portion 31 of the articulated arm 29 is placed on a support 33 represented by a continuous line on the figure 1 .
  • the second part 32 is connected to the disk 26 according to the invention.
  • This second part 32 is provided with a motor 34 making it possible to rotate the part 32 as well as the disc 26.
  • the rotational speed of this second part 32, and therefore of the disc 26, is adaptable according to the size of the screw 3.
  • This adaptation of the speed of rotation of the disk 26 is carried out using a control means, not shown, controlled by the power supply unit 25.
  • the rotational speed of the disk 26 is large enough to concentrate the glue 2 on the periphery 28 of the disk 26.
  • the two parts 31 and 32 are spaced apart at a spacing angle 35.
  • This separation angle 35 is chosen such that it allows the disk 26 to glue the lateral surface 9 only or the lateral surface 9 and the lower surface 11 of a screw 3 according to whether the gluing is carried out in front of or behind the plane defined by the line of advance of the screw 3 on the rail 5 and by the position of the screw 3 on the rail 5.
  • the disc 26 has a position such that this position allows the disc 26 to be in contact, at a given moment, at a time with at least one screw 3 moving on the rail 5 and with the glue 2 contained in the bin 27.
  • the contact between the screw 3 moving on the rail 5 and the disc 26 is effected by means of a contact angle 36, visible on the Figures 3a and 3b .
  • This contact angle 36 is chosen according to the size of the screw 3.
  • the angle of contact 36 is chosen such that the disc is in contact with the rod 7 of the screw 3 at the moment of the passage of the screw 3 on the rail 5.
  • the contact angle 36 between the screw 3 and the disc 26 is of the order of forty degrees. To adjust this contact angle 36, it is sufficient to adjust the spacing angle 35 of the two parts 31 and 32 and to move by sliding on the support 33, the portion 31 of the articulated arm 29 removable.
  • the tray 27 contains special glue 2 liquid and homogeneous so that this glue 2 does not form clumps or lumps.
  • the tray 27 containing the adhesive 2 is provided with a stirrer 37, figure 1 .
  • This stirrer 37 comprises an apparatus 38 and a magnet 39.
  • the apparatus 38 is located under the tank 27 and in one example, this stirrer is placed on the support 33.
  • the apparatus 38 is intended to rotate the magnet 39 located in the bottom of the tray 27.
  • the start of the motor, not shown, of this stirrer 37 is also controlled by the power supply unit 25.
  • the adhesive 2 used is a glue 2 of microcapsulated epoxy resin type.
  • This microencapsulated adhesive 2 has the advantage of being able to keep the screws 3 previously glued. These microcapsules will only discharge their contents once the screw is screwed into a hole.
  • the machine 1 operates in the following manner as shown in FIG. figure 1 .
  • the screws 3 are first deposited anyhow in the bottom of the bowl 4 at the location where the base 12 is located. Then, the machine 1 is started using the power supply unit 25.
  • the power supply unit 25 makes it possible to vibrate the bowl 4 and the rail 5 via the vibrating box 20.
  • the power supply unit 25 also makes it possible to operate the fan 21.
  • the bowl 4 enables the 3 screws to arrange regularly row of onions along the path 14.
  • the screws 3 are arranged in such a way that their head 8 is placed on the path 14 and that their rod 7 is arranged in the air. Once arrived at the top 13 of the bowl 4 vibrating, the screws 3 are distributed evenly in row of onions.
  • the disc 26 rotates continuously while partially bathing in the tray 27 containing the adhesive 2.
  • the centrifugal force of the disk 26 is such that this force promotes concentration glue 2 towards the periphery 28 sharpened disc 26.
  • the linear speed of the periphery 28 of the disc 26 is greater than the speed of displacement of the screw 3 located on the rail 5 before its contact with the disk 26.
  • the disk 26 communicates a rotational movement to the screw 3 fast enough to glue the rod 7 of the screw 3.
  • the screw 3 is propelled by this rotational movement to the outlet 17 of the rail 5 so that the screw 3 is glued at least over the entire periphery of at least a portion of the lateral surface of the rod 7. More precisely, as mentioned above, the screw 3 is glued in touch with the glue 2 concentrated at the periphery 28 of the disc 26. The screws 3 are then propelled onto the rail 5 always in the direction of displacement of the screw 3 after their contact with the disc 26 so that the screws 3 do not fit not in contact with each other once they are freshly sized.
  • Gluing of the screw 3 can be done in front of the screw 3, Figure 3a and 3b , relative to the plane defined by the line of advance of the screw 3 on the rail 5 and by the position of the screw 3 on the rail 5.
  • the contact of the periphery 28 of the disc 26 on the screw 3 is such that only the lateral surface 9 of the screw 3 is glued, Figures 3a, 3b and 4a .
  • Gluing of the screw 3 can also be performed behind the screw 3, figure 3c and 3d , relative to the plane defined by the line of advance of the screw 3 on the rail 5 and by the position of the screw 3 on the rail 5.
  • the contact of the periphery 28 of the disc 26 on the screw 3 is such that the entire periphery of at least a portion of the lateral surface 9 and the lower surface 11 of the screw 3 is glued, Figures 3c, 3d and 4b .
  • the freshly glued screws 3 are individually dried using the blower 21. After a few moments of drying, the screws 3 can then agglutinate at the outlet 17 of the rail 5 the time to reach the exit 17 to slide in the tray 24.
  • This contact area 41 is dependent on the inclination of the disc 26 relative to the rod 7 and is dependent on the sharpened shape of the periphery 28 of the disc 26. This sharp shape increases the contact area 41 of the disc 26 with the rod 7 in certain situations.
  • This contact zone 41 is reduced as the articulated arm 29 is pushed onto the rod 7 towards the rear relative to the plane defined by the line of advance of the screw 3 on the rail 5 and by the position of the screw 3 on the rail 5 when the gluing is carried out in front, figure 3b .
  • This contact zone 41 increases on the contrary as one pushes the articulated arm 29 on the rod 7 forward relative to the plane defined by the line of advance of the screw 3 on the rail 5 and by the position of the screw 3 on the rail 5 when the gluing is performed from behind, figure 3d .
