Description

  The present invention relates to a longitudinal vibration bonding apparatus in which a resonator having a cross-shaped vibration converting portion is horizontally mounted on a support that can be moved up and down and is mounted on both side supports.

  In the item of “4. Use of longitudinal vibration and lateral vibration” of Non-Patent Document 1, longitudinal vibration is used for ultrasonic bonding between a plurality of synthetic resin members, and a plurality of metal members are It is stated that lateral vibration is used for ultrasonic bonding. However, in an ultrasonic bonding machine for synthetic resin, the resonator that vibrates in the vertical direction is supported on one side, so when the object to be joined has a large part to be joined, the force of the large insulator acts on the resonator and the resonator tilts. The rigidity of the part that supports the resonator on one side is insufficient, the bonding varies, and vibration energy is lost. In addition, when the rigidity of the portion that supports the resonator on one side is insufficient as described above, the joining process cannot be controlled or monitored accurately. For example, even if a sensor such as a linear encoder for controlling the finished height of the object to be joined at the time of joining is equipped, the rigidity of the part that supports the resonator on one side is insufficient as described above. There is a drawback that the quality of the joint is poor, such as inability to control the height position.

The resonator 8 is illustrated as having a cross horn 11 having a cross shape when viewed from the front, two boosters 12, and one joining tool part 13. However, the resonator 8 can be applied without the joining tool part 13. When the welding tool part 13 is not provided, the end surfaces of the pair of protrusions 15 in the longitudinal direction of the cross horn 11 constitute the welding tool part 13. The two boosters 12 are provided at both ends of the pair of protrusions 14 in the lateral direction of the cross horn 11. The joining tool portion 13 is provided at the lower end of the pair of projecting portions 15 in the longitudinal direction of the cross horn 11.

In the opposed state, the joining target body 19 is mounted on the receiving portion 18. Next, as the pressurizing mechanism 3 is driven and the output member 4 is lowered, the joining target body 19 is pressed between the joining tool portion 13 and the receiving portion 18 from above and below to pressurize the resonator 8.

And joined. Thereafter, as the pressurizing mechanism 3 is driven and the output member 4 is raised, the joining tool part 13 is separated from the joining target body 19 and the joining target body 19 is left on the receiving part 18. The joining object 19 left on the receiving part 18 is taken out from the receiving part 18, and one joining operation with respect to the joining object 19 is completed.

  As the object 19 to be joined, a resin-to-resin joining structure in which a plurality of synthetic resin members made of thermoplastic synthetic resin are superimposed, a metal-to-metal joining structure in which a plurality of the same or different kinds of metal members are superimposed, the same kind or Structure of dissimilar material bonding in which resin pads are superposed on one or both of upper and lower parts of a plurality of different metal members, structure of dissimilar material bonding in which metal member and ceramic member are overlapped, metal member and ceramic Composition of dissimilar material joints in which resin pads are superposed on one or both of the upper and lower sides overlapped with members, composition of dissimilar materials joints in which metal members and synthetic resin members are superposed, metal members and synthetic resin members A configuration of bonding between dissimilar materials in which a resin pad is superimposed on one or both of the upper side and the lower side of the upper side and the lower side is conceivable. In addition, as the shape of the object 19 to be joined, a square shape, a round shape, or a planar variant can be used. That is, according to the longitudinal vibration bonding apparatus 1 shown in FIG. 1, the bonding between synthetic resin members, the bonding between metal members, and the bonding between different materials are possible.

  According to the longitudinal vibration bonding apparatus 1 shown in FIG. 1, the supported portions 10 of the two boosters 12 on both sides of the cross horn 11 are supported horizontally on both sides by the support 5 that can be raised and lowered.

Since the support 8 is horizontally mounted on both side supports, the resonator 8 does not tilt as much as the one-side support, and the quality of the joining is improved.

  In FIG. 1, the structure in which the pressurizing mechanism 3, the support 5, and the resonator 8 are disposed on the upper portion of the device housing 2 and the receiving portion 18 is disposed on the lower portion of the device housing 2 is illustrated. Further, a structure in which the pressurizing mechanism 3 and the receiving portion 18 are arranged, and the support 5 and the resonator 8 are arranged in the lower part of the device housing 2 is also applicable. The weight of the resonator 8 including one cross horn 11 and two boosters 12 and one joining tool part 13 that use ultrasonic vibration for joining is equal to one cross horn 11 and 2 that uses ultrasonic vibration for joining. It is much heavier than the weight of the resonator 8 composed of one booster 12 and one joining tool part 13. Therefore, when sonic vibration is used for joining, the receiving part 18 is attached to the output part 4 of the pressurizing mechanism 3 provided on the upper part of the apparatus housing 2, and the support 5 that supports the resonator 8 on both sides is provided. You may employ | adopt the structure installed in the lower part of the apparatus housing | casing 2. FIG.

  The members constituting the resonator 8 according to the embodiment for carrying out the invention shown in FIG. 2 will be described. The distance between the end faces of the pair of protrusions 14 in the lateral direction of the cross horn 11 shown in FIG. 2 and the distance between the end faces of the pair of protrusions 15 in the longitudinal direction of the cross horn 11 are transmitted from the vibrator 16. It can be applied even if it is a length corresponding to ½ wavelength of the sonic vibration or ultrasonic vibration or an odd integer multiple of the length corresponding to ½ wavelength. The cross horn 11 becomes small in length and width.

  The cross horn 11 is a vibration converting unit that converts the sonic vibration or the ultrasonic vibration transmitted from the vibrator 16 into the vibration in the vertical direction perpendicular to the horizontal direction from the vibration in the straight direction that goes straight as it is. The central portion where the transverse vibration that resonates with the sonic vibration or ultrasonic vibration transmitted from the vibrator 16 of the cross horn 11 and the longitudinal vibration converted from the transverse vibration into the longitudinal direction intersects with the minimum. Configure vibration amplitude points. The end faces of the pair of protrusions 14 in the lateral direction of the cross horn 11 constitute the maximum vibration amplitude point of the lateral vibration that resonates with the sonic vibration or ultrasonic vibration transmitted from the vibrator 16. The end faces of the pair of protrusions 15 in the longitudinal direction of the cross horn 11 are the maximum vibration amplitude points of the longitudinal vibration converted from the transverse direction to the longitudinal direction resonating with the sonic vibration or ultrasonic vibration transmitted from the vibrator 16. Configure. In short, the end surfaces of the pair of projecting portions 14 and the end surfaces of the pair of projecting portions 15 of the cross horn 11 constitute the maximum vibration amplitude point, and the lateral central portion of the cross horn 11 constitutes the minimum vibration amplitude point. In addition, the crossing portion of the vertical direction with the central portion in the horizontal direction constitutes the minimum vibration amplitude point, or the end surfaces of the pair of protrusions 14 and the end surfaces of the pair of protrusions 15 of the cross horn 11 are the maximum vibration amplitude. So that the vertical center of the cross horn 11 constitutes the minimum vibration amplitude point, and the intersection with the vertical center in the lateral direction constitutes the minimum vibration amplitude point. What is necessary is just to set the dimension of the vertical direction of the cross horn 11, and a horizontal direction.

  The lateral dimension of the booster 12 can be applied even if it is a length corresponding to ½ wavelength of the sonic vibration or ultrasonic vibration transmitted from the vibrator 16 or an integral multiple of the length corresponding to ½ wavelength. However, if the length is 1/2 wavelength, the booster 12 becomes small in size. The lateral end face of the booster 12 constitutes the maximum vibration amplitude point. A portion where the cross horn 11 and the booster 12 are coupled to each other constitutes a maximum vibration amplitude point. The booster 12 includes a supported portion 10 that is bent radially outward from the outer peripheral surface at the minimum vibration amplitude point of the booster 12, protrudes in an annular shape, and is integrally provided in a coaxial state. In short, the lateral dimension of the booster 12 may be set so that the lateral end face of the booster 12 constitutes the maximum vibration amplitude point.

  The outer peripheral surface of the supported portion 10 constitutes one circle that goes around the center of the booster 12 with one radius. As described above, the outer peripheral surface of the supported portion 10 is configured as one circle that goes around the center of the booster 12 with one radius, so that the two boosters 12 are cross-horns by the coupling tool 21 made of a headless screw or a screw rod. 1 is provided so that the lower end face of the joining tool part 13 is always parallel to the upper surface of the receiving part 18 even when coupled to both sides of the joint 11, and the joining object 19 shown in FIG. be able to. Since the pair of protrusions 14 and the two boosters 12 in the lateral direction of the cross horn 11 are coaxially coupled by the coupling tool 21 made of a headless screw or a screw rod, one cross horn 11 and two boosters 12 The structure of the bond becomes simple.

  The joining tool portion 13 is integrally coupled to the end face of the lower protrusion 15 in the longitudinal direction of the cross horn 11 in the longitudinal direction in a coaxial state by a coupling tool including a headless screw or a screw rod. The longitudinal dimension of the welding tool part 13 is applicable even if it is the length corresponding to 1/2 wavelength of the sound wave vibration or ultrasonic vibration transmitted from the vibrator 16 or an integral multiple of the length corresponding to 1/2 wavelength. Although it is possible, if the length is ½ wavelength, the joining tool portion 13 becomes vertically small. The longitudinal end surface of the welding tool portion 13 constitutes the maximum vibration amplitude point. A portion where the cross horn 11 and the welding tool portion 13 are coupled to each other constitutes a maximum vibration amplitude point. In short, the longitudinal dimension of the welding tool portion 13 may be set so that the longitudinal end face of the welding tool portion 13 constitutes the maximum vibration amplitude point.

  The lower end surface of the welding tool portion 13 can be applied in a shape such as a circle, a rectangle, a triangle, an ellipse, or an irregular shape that matches the bonding target body 19 so that the bonding target body 19 can be evenly pressurized. . In addition, as a whole shape of the joining tool part 13, shapes, such as a round bar shape and a square bar shape, are applicable. Since one joint tool portion 13 is coaxially coupled to the lower projection portion 15 of the pair of projection portions 15 in the longitudinal direction of the cross horn 11 by a coupling tool 22 made of a headless screw or a screw rod, The coupling structure between one cross horn 11 and one joining tool portion 13 is simplified.

  A vibrator 16 is integrally coupled to one end portion of one booster 12 on the opposite side of the cross horn 11 in a coaxial manner in a lateral direction by a coupling tool 23 made of a headless screw or a screw rod. An intermediate booster (not shown) is shown between one booster 12 and the vibrator 16, or between the cross horn 11 and the booster 12, or between the cross horn 11 and the joining tool part 13. It is also possible to integrally couple in a coaxial state in the lateral direction by means of a coupling tool comprising a headless screw or a screw rod that is not provided with a screw. The intermediate booster is for adjusting the amplitude of the resonator 8. By changing the magnification (shape) of the intermediate booster, the amplitude of the resonator 8 can be increased or decreased. When the intermediate booster is not used, the amplitude of the resonator 8 is the same as the amplitude of the vibrator 16, that is, 1 time. However, a 1 × intermediate booster may be used.

By pushing up around the hole 28, the vertical interval between the split grooves 27 is reduced, the diameter of the mounting hole 26 is reduced, and the supported part 10 of the resonator 8 disposed in the mounting hole 26 is supported by the supporting part 7. It is supposed to hold on.

The supported portion 10 of the resonator 8 is inserted into the mounting hole 26 so as to face the surrounding portion. In the state where the lower end surface of the joining tool portion 13 is in contact with the upper surface of the receiving portion 18 shown in FIG. 1 and is parallel to the upper surface of the receiving portion 18, the male thread portion 31 of the headed bolt 30 is As the head bolt 30 is artificially tightened with respect to the support portion 7 so that the amount of entry into the screw hole 29 is increased, the head 32 of the head bolt 30 is moved to the support portion 7. The supported portion 10 of the resonator 8 disposed in the mounting hole 26 is pushed up around the screw insertion hole 28 and held by the support portion 7, and the lower end surface of the welding tool portion 13 is always the upper surface of the receiving portion 18. Can be provided.
