Description

  The present invention relates to a mounting apparatus for pressurizing and pressing an electronic component on a substrate.

  For example, a TCP (Tape Carrier Package), which is an electronic component, is pressure-bonded to a liquid crystal cell as a substrate through an anisotropic conductive member as an adhesive material. The liquid crystal cell is configured by adhering two glass plates at a predetermined interval via a sealing agent, enclosing liquid crystal between these glass plates, and sticking a polarizing plate to the outer surface of each glass plate. The In the liquid crystal cell having the above-described configuration, the tape-like anisotropic conductive member is pressure-bonded to the upper surface of the edge, and the TCP is temporarily pressure-bonded on the anisotropic conductive member, and then the pressure-bonding is performed. .

  A mounting device is used when TCP is temporarily pressure-bonded to the substrate or when the film is pressure-bonded. As is well known, the mounting apparatus has an apparatus main body, and the apparatus main body is provided with a receiving member (backup) and a crimping tool that is driven up and down above the receiving member.

  The lower surface of the edge of the substrate to which TCP is attached via the anisotropic conductive member is placed on the upper end surface of the backup member, and then the TCP is temporarily bonded to the substrate by lowering the crimping tool. I try to do this.

  When TCP is permanently pressure bonded to the substrate, the pressure bonding head is heated to a high temperature in order to heat and cure the anisotropic conductive member. Therefore, when the TCP is heated under pressure by the pressure-bonding head, the anisotropic conductive member is heated and melted, and a part thereof may protrude from the TCP and adhere to the pressure-bonding head.

  If the anisotropic conductive member adheres to the crimping head, it may cause a pressure failure that prevents the TCP from being uniformly pressurized by the crimping head, or the anisotropic conductive member adhered to the crimping head may transfer to the TCP. It may cause dirt, which is not preferable.

  Therefore, when TCP is subjected to main pressure bonding, a heat-resistant sheet made of silicon resin or fluorine resin is interposed between the TCP and the pressure bonding head, so that when the TCP is heated under pressure, the melted anisotropy The conductive member is prevented from adhering to the crimping head.

  As a means for interposing the sheet between the TCP and the crimping head at the time of crimping, a cassette is mounted on the apparatus body, and the TCP is pressed against the substrate by the crimping head via the sheet provided in the cassette. It is. Such a technique is disclosed in Patent Document 1.

  By the way, since the board | substrate is increasing in size recently, the width dimension of the sheet | seat intervened between TCP and a crimping | compression-bonding head at the time of crimping | compression-bonding also becomes large according to it. As the width of the sheet increases, the cassette becomes larger and heavier.

  When a large and heavy cassette is set in the main body of the device, if the worker alone sets the cassette, the burden on the worker increases and the workability may be poor. .

Therefore, conventionally, a cart for delivering the cassette to the apparatus main body is used. A pair of rails is provided at both ends in the width direction of the upper surface of the carriage, and a cassette is placed on one end of the rails. It has been performed to slide along the rail and set in the apparatus body.
JP 2001-28382 A

  By the way, if the cassette is set in the apparatus main body using the carriage, the carriage is not necessary after the cassette is set in the apparatus main body. For this reason, the carriage must be cleared after the cassette is set, which may not only cause productivity loss and troublesome work, but also requires storage space to clear the carriage. It was. Moreover, since the trolley also becomes larger as the cassette becomes larger, the handling of the trolley may be troublesome.

  It is an object of the present invention to provide a mounting apparatus in which a cassette can be easily set in an apparatus main body without using a carriage.

A first arm having one end pivotally attached to the apparatus main body, and a second arm provided slidably on the first arm and projecting from the first arm and pivotally attached to the delivery member. It is preferable to include a support mechanism configured to support the transfer member in a horizontal state so as not to fall down when the transfer member is rotated and raised horizontally while extending the first and second arms.

  A pair of rails are provided in the apparatus body for sliding the cassette when the cassette is set, and the pair of transfer members are located at positions corresponding to the rails in the width direction and the height direction of the apparatus body. It is preferable to be provided.

  According to the present invention, since the delivery means is provided in the apparatus main body, the cassette can be set without using a carriage because it can be set in the apparatus main body by moving after placing the cassette on the delivery means. .

A TCP 5 as an electronic component is temporarily pressure-bonded to one side edge of the substrate 3 via an anisotropic conductive member 4.

  The apparatus main body 1 is provided with a receiving member 6 for receiving the lower surface of one side edge portion of the substrate 3 held by the XY table 2 by the upper end surface. A TCP 5 is temporarily crimped to the edge of the substrate 3 supported on the upper end surface of the receiving member 6, and the TCP 5 is finally crimped by a crimping tool 7.

  The crimping tool 7 is provided on the lower surface of the pressure head 8. The pressure head 8 is provided so as to be slidable in the Z direction, that is, in the vertical direction by the linear guide 9, and is driven in the Z direction by the Z drive source 10.

  A pair of rail members 11 are provided along the horizontal direction at height positions slightly above the receiving member 6 at both ends in the width direction of the apparatus main body 1. A cassette 12 can be attached to and detached from the apparatus main body 1 along the rail member 11. When the cassette 12 is mounted on the apparatus main body 1, a stopper (not shown) provided on the cassette 12 is brought into contact with a contact portion (not shown) provided on the apparatus main body 1 at a predetermined position. Thereby, the cassette 12 is positioned.

  As shown in FIGS. 1 and 2, the cassette 12 has a pair of rectangular side plates 14 connected by a connecting shaft 13 at a predetermined interval. The connecting shaft 13 connects at least the four corners of the side plate 14.

  A feeding shaft 16 as a feeding body in which a heat-resistant sheet 15 made of silicon resin or fluororesin is wound around one end in the longitudinal direction of the pair of side plates 14 is rotatable and detachable with respect to the side plates 14. Is provided.

  At the other end in the longitudinal direction of the side plate 14, a winding body 18 is provided for winding the sheet 15 wound around the feeding shaft 16 through a plurality of relay rollers 17. The winding body 18 has a winding drum 19 as shown in FIGS. End shafts 21 protrude from both ends of the take-up drum 19.

  One end shaft 21 is formed with a cylindrical hollow portion 22 opened at its end face. A relay shaft 23 is provided in the hollow portion 22 via a spring 24 so as to protrude and retract. One end portion of the relay shaft 23 is provided with a first pin 26 slidably engaged with a long hole 25 formed in the end portion shaft 21, and a second pin 27 is provided at the other end portion. ing. Therefore, the relay shaft 23 can project and retract in the axial direction within a range in which the first pin 26 slides along the long hole 25. A third pin 28 is provided on the other end shaft 21.

  Support shafts 31 are rotatably supported by bearings (not shown) at portions where the winding bodies 18 of the pair of side plates 14 are mounted. A support 34 having an engagement groove 33 opened on the outer peripheral surface is provided at one end of each support shaft 31 protruding toward the end surface of the side plate 14. The take-up drum 19 can be rotated by elastically engaging the relay shaft 23 and the other end shaft 21 against a biasing force of the spring 24 with a pair of receivers 34. And it is detachably attached.

  A driven gear 36 is fitted to an end portion of the one support shaft 31 on which the relay shaft 23 is mounted, protruding from the outer surface of the side plate 14. When the cassette 12 is mounted at a predetermined position on the apparatus main body 1 along the rail member 11, the driven gear 36 is a drive gear 39 that is fitted to a rotation shaft 38 of a drive motor 37 provided on the apparatus main body 1. It is designed to mesh with.

  When the cassette 12 is mounted on the apparatus main body 1, the driven gear 36 provided on the cassette 12 is vertically downward with respect to the drive gear 39 provided on the rotation shaft 38 of the drive motor 37, that is, the cassette on the apparatus main body 1. Positioned below the vertical direction perpendicular to the horizontal direction in which 12 is attached and detached, meshes with the drive gear 39.

  Then, when the cassette 12 is mounted at a predetermined position of the apparatus main body 1, a portion located between the feeding shaft 16 and the take-up drum 19 of the sheet 15 provided in the cassette 12 is temporarily pressed onto the substrate 3. It is arranged to face the upper side of TCP5.

  As shown in FIGS. 4 and 5, at both ends in the width direction of the front surface of the apparatus main body 1, a belt-plate-like structure that constitutes a delivery means for the cassette 12 at a position corresponding to the pair of rail members 11. A pair of delivery members 41 are provided. One end of the transfer member 41 is rotatably connected to both ends of the front surface of the apparatus main body 1 in the width direction by hinges 42. The pair of delivery members 41 can be held horizontally by being rotated by the support mechanism 43 from the state of being lowered downward as shown by the solid line in FIG. 4 in the upward direction indicated by the chain line in FIG. .

  The support mechanism 43 has a first arm 44 having one end pivotally attached to the front surface of the apparatus main body 1. The first arm 44 has a flat sheath shape, and a second arm 45 is slidably accommodated therein. One end of the second arm 45 protruding from the other end of the first arm 44 is rotatably connected to a bracket 46 provided on the lower surface of the other end of the transfer member 41 by a pin 47.

  A long hole 48 is formed in the side surface of the first arm 44 along the longitudinal direction. A stopper pin 49 provided at the other end of the second arm 45 is slidably engaged with the long hole 46. Accordingly, the second arm 45 can be slid within a predetermined range with respect to the first arm 44.

  Further, when the second arm 45 is projected from the first arm 44 to a predetermined position, the first arm 44 is prevented from sliding in the immersion direction at that position. A latch mechanism (not shown) is provided.

That is, when the delivery member 41 is rotated in the upward direction from the state in which the delivery member 41 is laid down to be substantially horizontal, the latch mechanism is operated at that position, and the delivery member 41 can be held in a non-fallable state. When the delivery member 41 in the horizontal state is rotated slightly upward from the horizontal state, the holding state by the latch mechanism is released. Thereby, the delivery member 41 can be laid down.
As shown in FIG. 5, a plurality of rollers 50 are provided at predetermined intervals in the longitudinal direction on the surface that becomes the upper surface when the delivery member 41 is erected horizontally. The upper end of the roller 50 is set at a position slightly higher than the upper surface of the rail member 11.

  In the mounting apparatus having such a configuration, in order to mount the cassette 12 on the apparatus main body 1, first, the delivery member 41 in the lying state as shown by the solid line in FIG. 4 is set in the upright direction as shown by the chain line in FIG. To turn up.

  When the delivery member 41 is rotated and raised, the second arm 45 slides relative to the first arm 44 and protrudes from the first arm 44. Then, when the delivery member 41 stands substantially horizontally, the second arm 45 is held in a non-slidable manner in the immersion direction with respect to the first arm 44 by a latch mechanism (not shown) at that position. That is, the delivery member 41 is held in a horizontal state so as not to be lowered.

  If the delivery member 41 is held horizontally, the operator places the cassette 12 on the upper surfaces of the pair of delivery members 41 as shown by the chain lines in FIGS. That is, both ends in the width direction of the cassette 12 are placed on the rollers 48 on the upper surfaces of the pair of delivery members 41. Then, the operator pushes the roller 50 through the cassette 12 while rolling it, transfers the roller 50 from the transfer member 41 to the rail member 11, and a stopper (not shown) provided in the cassette 12 is provided in the apparatus main body 1. The cassette 12 can be set at a predetermined position in the apparatus main body 1 by being pushed in until it comes into contact with a contact portion (not shown).

  When the cassette 12 is set at a predetermined position in the apparatus main body 1, the delivery member 41 is rotated upward from the horizontal state to release the holding state of the second arm 45 by the latch mechanism. Accordingly, since the delivery member 41 can be laid down in a substantially vertical state, after the cassette 12 is set in the apparatus main body 1, the delivery member 41 can be folded so as not to get in the way.

  When the cassette 12 is set in this way, a mounting operation is performed in which the electronic component 5 temporarily bonded to the substrate 3 is finally bonded. During the mounting operation, the sheet 15 mounted on the cassette 12 is sequentially wound from the feeding shaft 16 to the winding shaft 18, and a new portion of the sheet 15 is interposed between the receiving member 6 and the crimping tool 7. Thereby, the electronic component 5 can be reliably mounted.

  When the sheet 15 mounted on the cassette 12 is used up, the cassette 12 is taken out from the apparatus main body 1 and a new cassette 12 is set. Even when the cassette 12 is taken out from the apparatus main body 1, if the delivery member 41 is erected horizontally, the cassette 12 is slid along the rail member 11 to be taken out from the apparatus main body 1 and placed on the delivery member 41. . At that position, the operator carries out the cassette 12, places the new cassette 12 on the delivery member 41, and sets it in the apparatus main body 1 as described above.

  Thus, by providing the delivery member 41 in the apparatus main body 1, the cassette 12 can be delivered to the apparatus main body 1 without using a carriage as in the prior art. The delivery member 41 is provided on the apparatus main body so as to be raised and lowered. Therefore, since it can be laid down when not in use, it does not get in the way when not in use as in the case of using a carriage.

  In this embodiment, the cassette is described as being set by the transfer member from the front surface of the apparatus main body. However, the transfer member may be provided on the side surface of the apparatus main body, and the cassette may be set by sliding in the horizontal direction. Good.
