Description

  The present invention relates to a component mounter that collects components from an attached component supply device and mounts them on a substrate, and more particularly to an attachment structure that serves as both a positioning unit and a non-contact communication unit of the component supply device.

  There are a solder printing machine, a component mounting machine, a reflow machine, a board inspection machine, and the like as a board working device for producing a board on which a large number of parts are mounted, and a board production line is often constructed by connecting them. Of these, the component mounter generally includes a substrate transfer device, a component supply device, a component transfer device, and a control device. The substrate transfer device carries in and out the substrate and positions the substrate. The component supply device sequentially supplies components to a predetermined supply position. The component transfer device collects components from the component supply device and mounts them on the positioned substrate. The control device controls operations of the substrate transfer device, the component supply device, and the component transfer device.

  Of the component feeders, the cassette type feeder device is generally flattened in the vertical direction and in the front-rear direction and thin in the width direction, and is generally provided in a plurality of rows in the width direction of the component mounter. A direct attachment structure and a pallet attachment structure are used as the attachment structure of the plurality of component supply devices. In the direct attachment structure, the attached portion of the component supply device is directly attached to the attachment portion provided on the mounting base of the mounting machine body. In the pallet mounting structure, a pallet member having a plurality of mounting portions is used. More specifically, a plurality of component supply devices are previously mounted on the pallet member outside the component mounter, and the pallet member is mounted on the machine base together with the component supply device. Furthermore, the component supply device can be individually attached and detached on the mounted pallet member.

  The component supply apparatus has an electrical load such as a motor in a mechanism unit that supplies components, and also has an electrical load such as sensors. Furthermore, the component supply apparatus generally has a control unit that controls the component supply operation. This control unit communicates with the control device on the component mounter main body side, and exchanges information such as operation status, commands, and responses. Conventionally, a multi-terminal connector (multi-pin connector) has been used to supply power to an electrical load including a control unit and to perform communication between the control unit and the control device. However, in a multi-terminal connector, there is a risk of terminal deformation or breakage due to repeated insertion and removal operations. As countermeasures, Patent Documents 1 to 4 disclose examples in which contactless power feeding technology is applied to a component mounting machine.

  The component supply device of Patent Document 1 includes a primary coil fixedly arranged on the main body side of the component supply device, a secondary coil provided in the component supply cassette, and a control electronic circuit in the component supply cassette. And the control electronic circuit is driven by electric power supplied from the primary coil to the secondary coil. Further, the third and subsequent aspects disclose a mode in which power supply and control signals are transmitted and received by a plurality of electromagnetically coupled coils. Thereby, it is not necessary to connect using a connector etc., and troubles, such as a disconnection and contact failure, are eliminated.

  The surface mounting machine of Patent Document 2 is for positioning by inserting a positioning pin formed on a feeder into a positioning hole formed in a feeder mounting portion of a mounting machine body so that a primary coil surrounds the positioning hole. On the other hand, the positioning pin is provided with a secondary coil, and electric power is supplied from the primary coil to the secondary coil by electromagnetic induction. Thereby, it is supposed that electric power can be supplied to a feeder in a non-contact state with a simple configuration.

  In the inductive energy transfer device of Patent Document 3, a first magnetic core wound with a primary coil is assigned to a mounting automaton (component mounting machine body), and a second magnetic core wound with a secondary coil is a component. Assigned to the supply device, at least one of the magnetic cores is elastically supported. Thereby, reliable contact of the magnetic core is ensured, inductive energy is transmitted, and the plug can be omitted.

  In the electronic component mounting apparatus disclosed in Patent Document 4, a confirmation signal reciprocates between a non-contact power supply unit provided between the mounting unit and the electronic component supply unit, and an optical waveguide between the mounting unit and the electronic component supply unit. Thus, the apparatus includes a mounting detection unit that detects mounting of the electronic component supply device, and a control unit that starts power supply by the power supply unit after confirming the mounting of the electronic component supply device. Thereby, it is said that attachment detection can be performed without supplying power to the electronic component supply device side, and an attachment detection means and a standby power supply can be made unnecessary on the electronic component supply device side.

  By the way, although the technique of patent documents 2-4 is disclosing the structure of non-contact electric power feeding, there is no description regarding non-contact communication and a communication connector cannot be eliminated. Moreover, although the technique of patent document 1 is supposed to perform transmission / reception of a power supply and control signal by several coils, the arrangement | positioning position of a coil is restrict | limited. As described above, since the cassette type feeder device has a flat shape, if a plurality of coils (non-contact communication section, non-contact power feeding section) and positioning sections are arranged on a narrow mounting section, the mounting structure becomes complicated, and the parts There are also restrictions on the internal structure of the feeder. Moreover, since the opposing area of a non-contact communication part and a non-contact electric power feeding part is restrict | limited by the limited width dimension of a to-be-attached part, it is difficult to ensure the stable communication performance and electric power feeding performance.

  The present invention has been made in view of the problems of the background art described above, and even if the mounted portion of the component supply device is narrow, using a simple configuration in which the non-contact communication portion is incorporated in the positioning portion, It is an object to be solved to provide a component mounter that can stably perform unnecessary non-contact communication of a connector while ensuring the flexibility of the mounting structure and internal structure of a component supply device. Furthermore, it is an object to be solved to provide a component mounter that can stably perform non-contact communication and non-contact power feeding of a connector even when a mounted portion of a component supply device is narrow.

  The invention of the component mounting machine according to claim 1 that solves the above-described problem includes a machine base on which a mounting portion is arranged, a component supply device that has a mounted portion that is attached to the mounting portion, and supplies a component, A component transfer device that picks up the component from a component supply device and mounts the component on a substrate; and a control device that is provided on the machine base and controls the component supply device and the component transfer device. A component mounter for positioning a component supply device on the machine base by inserting a positioning boss formed on one of the mounted portions into a positioning hole formed on the other of the mounted portion and the mounted portion. A control side communication element provided on the inner wall of the positioning boss or the positioning hole formed in the mounting portion and connected to the control device, and an inner wall of the positioning hole formed in the mounted portion or A device-side communication element provided on the positioning boss and communicatively connected to the component supply device, and the control-side communication element and the device-side communication element when the positioning boss is inserted into the positioning hole. Is further provided with a non-contact communication device that enables non-contact communication between the control device and the component supply device.

  According to this, the control-side communication element and the apparatus-side communication element that become the non-contact communication part can be incorporated into the positioning boss and the positioning hole provided as the positioning part of the component supply device, and the configuration can be simplified. Therefore, the space for arranging the positioning unit and the non-contact communication unit is saved, and the degree of freedom of the mounting structure and the internal structure can be ensured even when the mounted portion of the component supply device is narrow. Further, the control-side communication element and the apparatus-side communication element can be increased in size by increasing the length of the positioning boss and the depth of the positioning hole. Therefore, the facing area between the control-side communication element and the apparatus-side communication element can be sufficiently secured without being limited by the limited width dimension of the attached portion, and unnecessary non-contact communication of the connector can be stably performed.

The protruding height H3 and width W3 of the upper positioning boss 36 and the lower positioning boss 37 are slightly smaller than the inner height H1 and the inner width W1 of the upper positioning hole 94 and the lower positioning hole 95. Therefore, the upper positioning boss 36 and the lower positioning boss 37 can be fitted into the upper positioning hole 94 and the lower positioning hole 95 from the front, and cannot be fitted from an oblique direction.

  Rectangular communication electrodes 721 to 724 are embedded in two side surfaces of the upper positioning boss 36 and the lower positioning boss 37, respectively. Each of the communication electrodes 721 to 724 starts from a position slightly behind the tips of the upper positioning boss 36 and the lower positioning boss 37 and extends to the base of the protrusion.
