Description

  The present invention relates to a component mounter that moves a mounting head to mount a component on a substrate.

  The component mounter positions the substrate by the substrate positioning unit, picks up the component supplied by the component supply device by the mounting head attached to the moving stage that moves relative to the substrate, and mounts it on the substrate. Here, the component supply device is detachably attached to the base, but by attaching the cart holding the plurality of component supply devices to the base in a state of being inserted into the cart insertion space formed at the bottom of the base. There is also known a component supply device batch replacement type component mounting machine in which a plurality of component supply devices are collectively fixed to a base.

Among such component mounters, there is known a component mounting machine in which a mounting head can be replaced with a different type (a different type of mounting head) (Patent Document 1). In this way, in a component mounter that can replace the mounting head with a different mounting head, a plurality of types of component mounting can be performed by one unit, and thus the productivity is very high.
Japanese Patent No. 3960054

  In addition, a head for another use (for example, a coating head for applying an adhesive or the like to the substrate) having a work purpose different from that of the mounting head is attached to the moving stage so that work other than the component mounting work is performed. It is also possible. However, in this case, since the parts supply device is not necessary, the carriage is not inserted into the carriage insertion space, and the carriage insertion space leading to the inside of the base remains open. Since the trolley insertion space has a part that allows direct access to the inside of the base, the purpose of covering the trolley insertion space is to insert a trolley that is not originally needed into the trolley insertion space, or to cover the trolley insertion space. It is necessary to prevent the operator from accidentally inserting a hand into the base by attaching the safety cover to the base. If the user has forgotten, there is a problem that the safety of the operator's work cannot be ensured.

  Therefore, the present invention provides a component mounter that can ensure the safety of the operator's work even when the mounting head is replaced with a head for another purpose and the carriage is not inserted into the carriage insertion space. For the purpose.

The component mounter according to claim 1 is a base including a substrate positioning unit that positions a substrate, a moving stage that is relatively movable with respect to the substrate positioned by the substrate positioning unit, A component supply device for supplying, a component supply device that holds the component supply device, and is attached to the base in a state of being inserted into a cart insertion space formed on the base, and is detachably attached to the moving stage and held on the cart A mounting head that picks up components supplied from the component supply apparatus and mounts them on the substrate positioned on the substrate positioning unit, operation control means for controlling the movement operation of the moving stage, and a base provided on the base Side connector, a trolley side connector provided on the trolley and coupled to the base side connector in a state where the trolley is attached to the base, and detachably attached to the moving stage The head is mounted on the base when there is no need to attach the carriage to the base because the head for other uses, which has a different work purpose from the mounted head, and the head for other uses is attached to the moving stage, and the interior of the base is A safety cover that covers at least a part of the portion that communicates with the safety cover, a safety cover connector that is provided on the safety cover and that is coupled to the base side connector in a state where the safety cover is attached to the base, and the base side connector is a cart And an operation restricting means for restricting the movement operation of the moving stage by the operation control means when not coupled to either the side connector or the safety cover side connector.

  A component mounter according to a second aspect of the present invention is the component mounter according to the first aspect, wherein the head for other uses applies an adhesive or the like to the substrate.

  In the component mounting machine of the present invention, in a state where the base side connector is not coupled to either the cart side connector or the safety cover side connector, the movement restricting operation is restricted by the action restricting means. Even if it is not necessary to insert the carriage into the carriage insertion space, the parts supply device is unnecessary because the head for the other purpose, which has a different work purpose from the mounting head, is attached to the moving stage. In order to operate the mounting machine, it is necessary to insert a carriage into the carriage insertion space or to attach a safety cover to the base.

The connectors 35 and 73 may be coupled to each other, or one or both of the connectors 35 and 73 are attached to the connector cord, and the safety cover 70 is attached to the base 3 and then separately. The connectors 35 and 73 may be manually coupled.

  In the coating operation by the component mounter 1, first, the operation control unit 24 a of the control device 24 operates the substrate transport path 4, and the substrate PB transferred from the upstream device is transferred from the substrate inlet 5 to the component mounter 1. It is carried in and positioned at a predetermined work position. Then, the moving stage 11 is moved in the horizontal plane so as to be positioned above the substrate PB, and the substrate camera 16 is caused to take an image of the substrate mark, thereby obtaining a positional deviation from the reference position of the substrate PB.

  When the operation control unit 24a of the control device 24 obtains the positional deviation of the substrate PB, the operation stage 24a moves the moving stage 11 above the substrate PB, and the adhesive supplied from the storage unit 52 for adhesive etc. is moved downward by the syringe 51.

The grasping method is not limited to the connection between the connectors shown in the present embodiment, but another method (for example, a part of the head attached to the moving stage 11 is detected by a non-contact type sensor or the like. May be).

Similarly, the control device 24 includes a connector on the base 3 side (base-side connector 35) and a connector on the work facility (cart 30 or safety cover 70) attached to the base 3 (cart side connector 36 or safety). By detecting that the cover side connector 73) is coupled, it is possible to grasp the state in which the work equipment is attached to the base 3, and the base side 43 side connector (base side side connector 45) and the base part 43 are attached. By detecting that the connector (nozzle changer-side connector 46 or discarding unit-side connector 63) on the working equipment (nozzle changer 40 or discarding unit 60) side is connected, the state where the working equipment is attached to the base portion 43 is shown. The control device 24 installed the work base 3 and the base unit 43 on the work table.

As described above, when the inspection head is used as a head for other purposes and the carriage insertion space SP remains open, a safety cover as described above is required, and the safety cover is attached to the base 3. Although the above-described effects of the present invention can be obtained by mounting, in the case of using an inspection head, a measuring device such as a personal computer may be inserted into the cart insertion space SP as work equipment together with the transport cart. The carriage insertion space SP is not always open to the outside. On the other hand, when the application head 50 is used as a head for other purposes, work equipment is not usually inserted into the carriage insertion space SP, and the carriage insertion space SP remains open to the outside. In the case where the coating head 50 is used as a head for other purposes, the effect of the present invention is significant.
