Description

  The present invention relates to a component crimping apparatus that presses and crimps a component previously mounted on a substrate against the substrate.

  A component crimping device used in a liquid crystal panel production line or the like is a device that crimps a component such as a driver to the edge of a panel-like substrate. The parts are mounted on the substrate in advance (temporary pressure bonding) through an adhesive made of an anisotropic conductive member called ACF (Anisotropic Conductive Film), and the parts are pressed against the board by pressing the parts with a pressure bonding tool (this Crimp). A protective tape is installed between the crimping tool and the component, and the adhesive is not attached to the crimping tool by stepping on the protective tape when the crimping tool presses the component.

  In such a component mounting apparatus, the protective tape is fed by the tape feeding mechanism, and the used part is ejected from the tape feeding mechanism and discarded in a disposal box (for example, Patent Document 1). Also, in some parts crimping devices, the protective tape discharged from the tape feeding mechanism is not discarded directly into the disposal box due to its structure, but the protective tape discharged from the tape feeding mechanism is disposed on the slope of the disposal guide path. Some of them receive it in the direction of disposal.

  2 and 4, the waste guiding path 51 extends upward from both ends of the swash plate 61, and a swash plate 61 having a slope 61 a extending obliquely rearward and downward from a position directly below the rear end of the protective tape installation unit 15. A pair of guiding guides 62 provided. The disposal path 52 includes an inclined plate 63 having an inclined surface extending obliquely downward and rearward from the vicinity of the lower end of the swash plate 61 of the disposal guide path 51, and a pair of disposal guides provided extending upward from both ends of the inclined plate 63. 64. The slope of the discard path 52 is steeper than the slope 61 a of the discard guide path 51. The inclined surface of the disposal path 52 is located above the disposal box BX.

  In FIG. 4, the air ejection part 53 includes a tubular member 71 provided in the discard guiding path 51, an air pipe 72 connected to the tubular member 71, and an air supply part 73 that supplies air to the tubular member 71 through the air pipe 72. It is configured with. As shown in FIG. 5, the tubular member 71 is located at an upper position along the inclined surface 61 a (an upper left position in FIG. 5) than a position 61 b below the tape discharge portion 46 on the inclined surface 61 a included in the discard guiding path 51. , Extending in the X-axis direction (that is, in a horizontal direction parallel to the inclined surface 61a). The tubular member 71 includes a plurality of air jets 71a arranged in the X-axis direction, and each air jet 71a opens downward along the slope 61a (FIG. 5). When the air supply unit 73 supplies air to the tubular member 71 via the air pipe 72, the air Lf is ejected downward from the plurality of air ejection ports 71 a included in the tubular member 71 along the inclined surface 61 a.

  In FIG. 6, each control of the lifting motor 22, the pressure cylinder 24, the table moving mechanism 14 b, the roller drive motor 36, and the air feeding unit 73 is performed by the control device 80 included in the component crimping device 1. In the crimping operation of the component 3 by the component crimping apparatus 1, first, the substrate positioning unit 14 is operated to position the substrate 2 on which the component 3 is previously mounted at a predetermined work position. Here, the “working position” refers to a position where the lower surface side of each component 3 provided on the substrate 2 is supported by the backup unit 13.

  In positioning the substrate 2 to the working position, the table moving mechanism 14b moves the substrate holding table 14a holding the substrate 2 (arrow A shown in FIG. 7A) and is mounted (preliminarily pressed) on the substrate 2. Each of the plurality of parts 3 is positioned below the crimping tool 25 (above the backup unit 13). When the substrate 2 is thus positioned at the work position, the lifting motor 22 is actuated to lower the lifting base 23 and each crimping tool 25 is positioned at the initial position above the protective tape 31 (in FIG. 7A). Arrow B).

  When each crimping tool 25 is located at the initial position, the roller drive motor 36 rotates each feed roller 44 (arrow C shown in FIG. 7A). When the feed roller 44 rotates, the pinch roller 45 rotates in the opposite direction to the feed roller 44 (arrow D shown in FIG. 7A), and the protective tape 31 is sandwiched between the feed roller 44 and the pinch roller 45. Pulled backward from the supply reel 42. As a result, when the unused portion of the protective tape 31 is positioned below the crimping tool 25, the pressure cylinder 24 pushes down each crimping tool 25 from the initial position (arrow E shown in FIG. 7B).

  The crimping tool 25 pushed down by the pressure cylinder 24 steps on the protective tape 31 and presses the component 3 against the substrate 2. When the crimping tool 25 presses the component 3 against the substrate 2, the component 3 is pressed against the backup unit 13 together with the substrate 2 (FIG. 7B), and the component 3 is crimped to the substrate 2 (main crimping). Since the protective tape 31 is interposed between the crimping tool 25 and the component 3 when the component 3 is pressed against the substrate 2 by the crimping tool 25, the crimping tool 25 does not come into contact with the adhesive, and the adhesive is applied to the crimping tool 25. It is prevented from adhering.

  When the crimping tool 25 presses the component 3 against the substrate 2, the pressure cylinder 24 raises the crimping tool 25 and returns it to the initial position (FIG. 7A). When the crimping tool 25 returns to the initial position, the roller drive motor 36 rotates the feed roller 44 (arrow C shown in FIG. 7A) and pulls out a certain amount of the protective tape 31 from the supply reel. As a result, the used portion 31F of the protective tape 31 stepped on by the crimping tool 25 by the crimping operation of the component 3 by the crimping tool 25 is sent backward, and the lower portion (stepping portion) of the crimping tool 25 is the used portion. The unused part is updated from 31F.

  When the tape feeding mechanism 32 performs the feeding operation of the protective tape 31 and updates the used portion 31F of the protective tape 31 to the unused portion as described above, the above-described crimping operation procedure (positioning of the substrate 2 and the crimping tool 25) is performed. The pressing of the part 3 is repeated. Thus, the feeding operation of the protective tape 31 performed by the tape feeding mechanism 32 is an intermittent feeding operation, and the used portion 31F of the protective tape 31 is fed backward by repeating the updating operation of the protective tape 31, and the feeding roller 44 Is passed through the tape discharge portion 46 between the feed roller 44 and the pinch roller 45 so as to hang down under its own weight.

  As described above, in this embodiment, the tape feeding mechanism 32 of the protective tape installation unit 15 performs the intermittent feeding operation of the protective tape 31 in conjunction with the crimping operation of the component 3 by the crimping tool 25, and the crimping tool of the protective tape 31. 25, the part to be stepped on is updated, and the crimping tool 25 presses the component 3 against the substrate 2 to advance the used part 31F of the used protective tape 31 to be discharged from the tape discharge part 46. Yes.

  In FIG. 3, the used portion 31 </ b> F of the protective tape 31 that is discharged from the tape feeding mechanism 32 and hangs down by its own weight comes into contact with the inclined surface 61 a of the discard guiding path 51 located below the tape discharging portion 46 from above. The used portion 31F of the protective tape 31 in contact with the inclined surface 61a slides downward on the inclined surface 61a with its own weight, and is guided in the discarding direction, that is, in the direction of the disposal path 52 positioned below (FIG. 4). Thus, in the present embodiment, the discard guiding path 51 is a used portion of the protective tape 31 discharged from the tape discharge portion 46 by the inclined surface 61a positioned below the tape discharge portion 46 of the tape feeding mechanism 32. 31F is slid by its own weight and guided in the direction of disposal.

  Here, the control device 80 supplies air from the air supply unit 73 to the tubular member 71 while the protective tape feeding mechanism 32 advances the used portion 31F of the protective tape 31 by the intermittent feeding operation of the protective tape 31. Then, the air Lf is intermittently ejected from a plurality of air ejection ports 71a included in the tubular member 71. As a result, the position 61b of the inclined surface 61a below the tape discharging portion 46 (that is, the position where the protective tape 31 hanging from the tape discharging portion 46 is in contact with the inclined surface 61a) is directed downward from the upper surface to the inclined surface 61a ( That is, the air Lf is supplied (in the direction in which the protective tape 31 slides) (FIG. 5).

  As described above, in the present embodiment, the air ejection portion 53 ejects air from the air ejection port 71a that opens downward along the slope 61a, and protects the slope 61a and the slope 61a from sliding. An air layer is formed between the tape 31 and the tape 31. For this reason, it is hard to occur that the protective tape 31 hanging from the tape discharge portion 46 and contacting the slope 61a sticks to the slope 61a due to friction. It slides down. Here, the ejection of air is performed when the protective tape 31 may stick to the inclined surface 61a, and the protective tape feeding mechanism 32 causes the used portion 31F of the protective tape 31 to advance by the intermittent feeding operation of the protective tape 31. Since it is performed only during the period, useless air ejection is prevented.

  The protective tape 31 guided to the disposal path 52 by the disposal guidance path 51 slides down on the inclined surface of the disposal path 52 and is accommodated in the disposal box BX. Thereafter, the protective tape 31 accommodated in the disposal box BX is discarded by the operator OP.

  As described above, in the component crimping apparatus 1 according to the present embodiment, air is ejected onto the slope 61 a of the disposal guide path 51 to form an air layer between the slope 61 a and the protective tape 31. Is difficult to stick to the slope 61a. For this reason, a normal feeding operation of the protective tape 31 can be ensured, and a decrease in productivity in the component crimping apparatus 1 can be prevented. In addition, the ejection of air toward the slope 61a is performed when the protective tape 31 is stuck to the slope 61a, and the protective tape 31 is used by the protective tape feeding mechanism 32 intermittently feeding the protective tape 31. Since it is performed only while the portion 31F is being advanced, useless air ejection is prevented, and the effect of reducing power consumption and noise due to air ejection can be obtained.

  In the above-described embodiment, the protective tape 31 discharged from the tape feeding mechanism 32 passes through the disposal guide path 51 and then passes through the disposal path 52 and is accommodated in the disposal box BX. The waste box 52 may be accommodated in the waste box BX without passing through the waste path 52. Further, the disposal box BX may not be provided, and the protective tape 31 may be disposed on the floor surface.

  Provided is a component crimping apparatus capable of ensuring a normal feeding operation of a protective tape.
