Description

  The present invention relates to a cassette delivery carriage for delivering a cassette having a sheet used when pressurizing and crimping an electronic component to a substrate to a mounting apparatus.

  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 on 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. The mounting apparatus is provided with a receiving member (backup) and a crimping tool that is driven up and down above the receiving member.

  When the TCP is pressure-bonded to the substrate, the lower surface of the edge of the substrate to which the TCP is attached via the anisotropic conductive member is placed on the upper end surface of the backup member. Then, the TCP is temporarily or permanently bonded to the substrate by lowering the crimping tool.

  When TCP is permanently pressure bonded to the substrate, the pressure bonding tool 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 crimping head, the anisotropic conductive member is heated and melted, and a part thereof may stick out of the TCP and adhere to the crimping tool.

  If the anisotropic conductive member adheres to the crimping tool, it may cause a press failure that prevents the TCP from being uniformly pressed by the crimping tool, or the anisotropic conductive member adhered to the crimping tool 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 tool, so that when the TCP is heated under pressure, the melted anisotropy The conductive member is prevented from adhering to the crimping tool.

  As a means for interposing the sheet between the TCP and the crimping tool at the time of crimping, the cassette is mounted on a delivery table provided in the mounting apparatus, and the TCP is attached to the substrate by the crimping tool via the sheet provided in the cassette. Pressing is performed.

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

  When a large and heavy cassette is mounted on the mounting device, or when a used cassette is removed from the mounting device, the worker must carry the cassette by himself. There are cases where the burden on the vehicle becomes large and workability is poor.

  Therefore, conventionally, the delivery cart shown in Patent Document 1 is used to deliver the cassette to the mounting apparatus. The delivery carriage is provided with a pair of rails along the front-rear direction intersecting the width direction at both ends in the width direction of the upper surface, and the delivery carriage is supported by engaging the cassette with both ends in the width direction. Is positioned on the front surface of the mounting apparatus, and the cassette is slid along the rail and transferred to a delivery table provided in the mounting apparatus.

In addition, if the sheet provided on the cassette is used up, the carriage is positioned on the front surface of the mounting device, the cassette is removed by sliding it from the delivery table of the mounting device to the rail of the carriage, and the new cassette is also used with the delivery cart. It is attached to the support part of the mounting device.

For this reason, if the cassette sheet mounted on the mounting device is used up, the cassette is first transferred from the mounting device to the upper surface of the delivery carriage and moved to the storage location, and then is not placed on the upper surface of the delivery carriage. It has been carried out that a cassette to be used is loaded, transported to the mounting apparatus, and mounted on the mounting apparatus.

  That is, the used cassette is first transferred from the mounting device to the carriage, the cassette is lowered from the carriage, the unused cassette is transferred to the carriage, and then the cassette is mounted on the mounting apparatus.

  For this reason, since the delivery carriage must be moved twice with respect to the mounting apparatus when removing the used cassette from the mounting apparatus and when an unused cassette is mounted, it takes a lot of trouble to replace the cassette. It took a long time and resulted in a decrease in productivity.

  It is an object of the present invention to provide a cassette delivery carriage in which removal of used cassettes and installation of unused cassettes can be performed in one operation without re-loading these cassettes. is there.

  In FIG. 10, the apparatus main body 3 of the mounting apparatus 1 is indicated by a chain line. The structure of the apparatus main body 3 is substantially the same as that shown in the first embodiment in that it has a pair of support rails 14, but the transfer table 20 is not provided on the front surface of the apparatus main body 3. It is different in point.

Next, a procedure for delivering the cassette 16 using the cart 2A having the above configuration will be described with reference to FIGS.
FIG. 11 shows a state in which the used cassette 16A held in the apparatus main body 3 is taken out, and an operator (not shown) removes the used cassette 16A after using the sheet 19 along the support rail 14. It is pulled out to the front side of the apparatus main body 3 indicated by an arrow X in FIG.

  When the used cassette 16A is pulled out to the front side of the apparatus body 3, the carriage 2A is positioned on the front surface of the apparatus body 3 as shown in FIG. One end of the first movable rail 76 on which the first spacer 79 is provided is made to enter the lower surface of the used cassette 16 </ b> A drawn to the front surface in the apparatus main body 3.

Next, the rotating shaft 52 is rotated by the lever 53 to raise the rotating body 65. When the rotating body 65 is raised, the used cassette 16A is scooped up from the support rail 14 by one end of the first movable rail 76 provided with the first spacer 79, and floats.
An unused cassette 16B is supplied and placed in advance on the second spacer 80 of the pair of second movable rails 78 on the upper surface of the rotating body 65.

  Thus, when the rotating body 65 is rotated and the unused cassette 16B is positioned on the apparatus main body 3 side, the unused cassette 16B is pushed into the apparatus main body 3 side as shown in FIG. The unused cassette 16B is placed on the second spacer 80 of the second movable rail 78, and the thickness of the second spacer 80 is between the lower surface and the upper surface of the first movable rail 76. A gap corresponding to the height is formed.

  Therefore, when the unused cassette 16B is pushed into the apparatus main body 3, the cassette 16B does not interfere with the upper surface of the first movable rail 76. As a result, the second movable rail 78 slides smoothly with respect to the first fixed rail 75, so that the operation can be performed easily and reliably.

  If the unused cassette 16B is pushed to a predetermined position on the support rail 14 as shown in FIG. 14, the lever 53 provided on the vehicle body 22 is rotated to lower the rotating body 65, and the unused cassette 16 The lower surfaces of both end portions in the width direction of 16B are engaged and held with the upper surfaces of the end portions on the front side of the apparatus main body 3, which are one end portions of the pair of support rails.

  In this way, if the unused cassette 16B is engaged and placed on one end of the support rail 14 of the apparatus main body 3, the second movable rail 78 is slid and returned onto the rotating body 65, The carriage 2A is moved to a position away from the front surface of the mounting apparatus 1. Next, an unused cassette 16B placed on one end of the support rail 14 is pushed into a predetermined position inside the apparatus main body 3. As a result, the operation of taking out the used cassette 16A from the apparatus main body 3 and transferring the unused cassette 16A to the apparatus main body 3 is completed.

  Even with the carriage 2A having such a configuration, as in the first embodiment, it is easy to take out the used cassette 16A from the apparatus main body 3 and mount the unused cassette 16B on the apparatus main body 3. And since it can carry out rapidly, the improvement of workability | operativity can be aimed at.
