Description

  The present invention relates to an electronic component mounting apparatus that performs a component mounting operation for mounting an electronic component on a substrate, and an electronic component mounting work execution method that executes a work operation in the electronic component mounting apparatus.

  Electronic component mounting devices such as screen printing devices and component mounting devices used in electronic component mounting lines that mount electronic components on a substrate to produce a mounting substrate are transport conveyors that transport substrates from upstream to downstream. A substrate transport mechanism is provided. As substrates to be worked in these electronic component mounting apparatuses, there is a so-called double-sided mounting substrate on which electronic components are mounted on both sides as well as one side of the substrate. In the mounting process of the double-sided mounting substrate, first, mounting on the first surface is performed, and then the substrate is reversed and mounting on the second surface is performed. When mounting on the second surface, the first surface, that is, the already mounted surface on which the electronic component is mounted faces downward, so that the electronic component becomes an obstacle when the substrate is positioned and held at the mounting position. Therefore, it is not possible to directly support the already mounted surface. For this reason, a method is used in which an under-mountable portion other than the electronic component mounting portion on the already-mounted surface is appropriately selected and this position is supported by the under-loading pin (see, for example, Patent Document 1). In the prior art example shown in this patent document, the back-up plate that holds the back-up pins offline outside the apparatus is turned upside down from the state in which the back-up plates are actually installed in the transport device, and the back-up pins are used as the back-up plates. An example of temporary fixing is shown. Then, every time the target board type is switched, a setup change operation for changing the arrangement of the receiving pins according to the board type is executed.

Japanese Patent No. 3904429

  However, in the prior art including the above-mentioned patent documents, there has been the following inconvenience in the setup change operation for changing the arrangement of the receiving pins. That is, when the already mounted surface on which the electronic component is mounted becomes the lower receiving surface, the lower receiving pin and the substrate. The relative position must be determined appropriately in consideration of the position of the already mounted components on each board. For this reason, in the prior art, in order to specify the position of the substrate in the substrate transport mechanism, the operator performs the substrate transport operation to actually position the substrate, or the position reference mark indicating the position of the substrate in the work operation position Needed to be prepared separately. In the case of a multi-product, low-volume production form with multiple substrate types to be worked on, the placement of the receiving pins accompanying such substrate type switching is frequently performed, and complicated operations are repeatedly performed. Had been forced to do.

  Therefore, the present invention provides an electronic component mounting apparatus and an electronic component mounting operation that can efficiently perform the work of rearranging the receiving pins accompanying the switching of the substrate types in a production mode in which a plurality of substrate types are to be worked.

By changing the stopper moving mechanism based on the previously stored substrate type data, the arrangement of the plurality of receiving pins is changed according to the target substrate type. In order to prevent the substrate stopper unit from obstructing the execution of the setup change operation during the setup change operation, a setup change control treatment section for aligning with respect to the rear end surface on the upstream side of the substrate is provided.

  Next, embodiments of the present invention will be described with reference to the drawings. First, the overall configuration of the component mounting apparatus 1 will be described with reference to FIG. The component mounting apparatus 1 has a function of mounting an electronic component on a substrate, and is an electronic component mounting device that executes an electronic component mounting operation for mounting the electronic component on the substrate.

  In FIG. 1, a substrate transport mechanism 2 is disposed on a base 1a in the X direction (substrate transport direction). The substrate transport mechanism 2 transports the substrate 3 on which electronic components are mounted and received from the upstream pre-process device from the upstream side to the downstream side in the substrate transport direction, and the component mounting position (work) set on the substrate transport mechanism 2 The substrate 3 is positioned at the operation position). Then, the board 3 on which the electronic component is mounted by the component mounting mechanism (work operation mechanism) described below at the mounting position is delivered to the downstream post-process device.

  Here, at the component mounting position, a substrate lowering mechanism 20 having a function of receiving the positioned substrate 3 from the lower surface side by a plurality of lower receiving pins 25 (see FIG. 3) is disposed. The substrate support mechanism 20 is provided so that the arrangement of the support pins 25 can be changed according to the target substrate 3, and the substrate mounting type substrate 3 in which electronic components are already mounted on one side in the previous process is operated. It is possible to target. In other words, different types of double-sided mounting boards can be received by selecting in advance a supportable area in which no mounted parts are present on the lower surface side of the board 3 and changing the arrangement of the receiving pins 25.

  Component supply units 4 are provided on both sides of the substrate transport mechanism 2, and a plurality of tape feeders 5 are attached to the component supply unit 4. The tape feeder 5 pitches the carrier tape holding the electronic component, thereby supplying the electronic component to a component pick-up position by a component mounting mechanism described below.

  A Y-axis moving table 7 having a linear drive mechanism is disposed horizontally in the Y direction at one end of the base 1a in the X direction. Similarly, two X-axis movement tables 8 having linear drive mechanisms are slidably coupled to the Y-axis movement table 7 in the Y direction. Each X-axis movement table 8 has a plurality of lower end portions. A mounting head 9 provided with a suction nozzle 9a (see FIG. 3B) is slidably mounted in the X direction.

  The X-axis moving table 8 is provided corresponding to each component supply unit 4 disposed on both sides of the substrate transport mechanism 2. By driving the Y-axis moving table 7 and the X-axis moving table 8, the mounting head 9 moves in the horizontal direction, takes out the electronic components from the tape feeder 5 of each component supply unit 4, and mounts the board transport mechanism 2. It is transported and mounted on the substrate 3 positioned at the position. In the above configuration, the Y-axis moving table 7, the X-axis moving table 8, and the mounting head 9 constitute a component mounting mechanism, and this component mounting mechanism performs a component mounting operation that is a work operation for an electronic component mounting operation. It is an operating mechanism.

  A component recognition device 6 is disposed between the component supply unit 4 and the board transport mechanism 2, and when the mounting head 9 that takes out the electronic component from the component supply unit 4 moves above the component recognition device 6. The component recognition device 6 captures and recognizes the electronic component held by the mounting head 9. In the component mounting operation by the mounting head 9, position correction when aligning the mounting head 9 with respect to the substrate 3 is performed based on the component recognition result by the “component recognition device 6”.

  Next, the detailed configuration of the substrate transport mechanism 2 will be described with reference to FIGS. As shown in FIG. 2, the substrate transport mechanism 2 is composed of three transport conveyor mechanisms, that is, from the upstream side (left side in the figure), a carry-in conveyor 2a, a mounting conveyor 2b, and a carry-out conveyor 2c. 2b and the carry-out conveyor 2c each convey the substrate 3 by a pair of belt conveyor mechanisms 10. Among these conveyor mechanisms, the carry-in conveyor 2a has a function as a standby conveyor that waits for the board 3 carried from the upstream device, and the mounting conveyor 2b is a board delivered from the carry-in conveyor 2a. 3 is transported to the component mounting position [P] and positioned. The carry-out conveyor 2c has a function of carrying the mounted board 3 to the downstream side.

  The central portion of the mounting conveyor 2b is a component mounting position [P] (work operation position) where a component mounting operation (work operation) is performed on the substrate 3. The substrate 3 carried into the component mounting position [P] is clamped and fixed by the clamper 11 while being positioned at a predetermined reference position by a substrate stopper unit 12 described below, and is below the lower surface side by the substrate receiving mechanism 20 described above. These supportable regions are pin-supported by a plurality of receiving pins 25 (see FIG. 3).

  A substrate stopper unit 12 provided with a stopper mechanism 13 for positioning the substrate 3 is disposed in the substrate transport mechanism 2 so as to be movable along the substrate transport direction. The board stopper unit 12 is reciprocated within the stopper movement range including the mounting conveyor 2b from the carry-in conveyor 2a (arrow a) by the stopper moving mechanism 14 having a linear drive mechanism (not shown), and can be stopped at an arbitrary position. It has become. In the normal state, the substrate stopper unit 12 stands by at a standby position set in the carry-in conveyor 2a as shown in FIG.

  When the component mounting operation is performed, as shown in FIG. 2B, the board stopper unit 12 is moved to the mounting conveyor 2b and stopped at the reference position for positioning the board 3 at the component mounting position by the stopper mechanism 13. Let At this time, the substrate stopper unit 12 stops so that the substrate 3 is positioned at the component mounting position in a state where the contact member 19 provided in the stopper mechanism 13 contacts the distal end surface 3a on the downstream side of the substrate 3. A reference position is set. That is, the board stopper unit 12 is provided so as to be movable in the board carrying direction in the board carrying mechanism 2, and at a component mounting position [P] (working operation position) where a component mounting operation (working operation) is performed on the board 3. The stopper moving mechanism 14 has a function of moving the substrate stopper unit 12 in the substrate transport direction and positioning it at an arbitrary position.

  As shown in FIG. 3A, the substrate support mechanism 20 includes a support unit 22 that can be moved up and down by a lift drive unit 21. The lower receiving unit 22 has a structure in which two horizontal pin support plates 23 and 24 are disposed above a base portion 22a coupled to the elevating drive unit 21, and each of the pin support plates 23 and 24 has a structure. Pin support holes 23a and 24a are formed in a lattice arrangement. The lower receiving pin 25 is disposed through the pin support holes 23 a and 24 a located at a position corresponding to the supportable region on the lower surface of the substrate 3. As shown in FIG. 3 (b), the lower receiving unit 22 is lifted together with the lower receiving pins 25 by driving the elevating drive unit 21 (arrow b), whereby the lower receiving pins 25 are moved on the lower surface side of the substrate 3. The part 26 is in contact with the supportable area where there is no support and is supported from below.

  Next, the structure and function of the substrate stopper unit 12 will be described with reference to FIG. As shown in the plan view of FIG. 4A, the substrate stopper unit 12 is mainly composed of a substantially triangular planar member 12a, and a base portion 12b located on the bottom side in this triangle is coupled to the stopper moving mechanism 14. The top side is mounted in a posture extending to the inside of the substrate transport mechanism 2. On the upper surface of the base portion 12b, the cylinder 15 is disposed in a posture in which the rod 15a faces the X direction, and the rod 15a is connected to the drive transmission portion 16. A drive rod 17 extends from the drive transmission portion 16 in the Y direction, and the drive rod 17 rotates around its axis when the rod 15a performs a projecting and retracting operation. On the front end surface 12c of the substrate stopper unit 12, a stopper mechanism 13 having a configuration in which a rectangular block-shaped abutting member 19 is rotatably held in the vertical direction with the shaft coupling portion 19a as a rotation fulcrum is provided in the X direction. The drive rod 17 is connected to the shaft coupling portion 19a.

  In the state where the rod 15a is immersed, as shown in FIG. 4B, the contact member 19 extends from the substrate stopper unit 12 to the downstream side in a horizontal posture. Then, by driving the cylinder 15 and projecting the rod 15a, as shown in FIG. 4C, the drive rod 17 rotates in the clockwise direction, whereby the contact member 19 rotates in the arrow d direction. It becomes a drooping posture. In this state, in the process in which the substrate 3 is conveyed downstream by the mounting conveyor 2b, the front end surface 3a of the substrate 3 comes into contact with the rear end surface 19b of the contact member 19, so that the substrate 3 can be used for component mounting operation. Positioned at the reference position.

  Since the arrangement of the receiving pins 25 in the board receiving mechanism 20 differs depending on the board type, when the board type is switched in the process of continuously executing the component mounting operation for a plurality of board types, A setup change operation for changing the arrangement of the lower receiving pins 25 is performed. In this setup change operation, the target one-side mounted substrate 3 is positioned at the component mounting position [P], and the operation for checking the presence / absence of interference between the receiving pin 25 and the already mounted component is repeatedly executed. The board 3 is required to be easily aligned with the component mounting position [P].

  In the conventional apparatus, the positioning of the board 3 in this setup change operation is performed by causing the board conveyor operation by the mounting conveyor 2b to actually position the board 3 at the component mounting position [P] or at the component mounting position [P]. A complicated operation such as separately preparing a position reference mark indicating the position of the substrate 3 is required. In the present embodiment, in order to eliminate such complicated work, the function of the board stopper unit 12 provided movably is not limited to the positioning of the board 3 during the component mounting operation, but the board during the setup change work. 3 is used for alignment.

  In the state where the substrate 3 is positioned by the substrate stopper unit 12, as shown in FIG. 2B, the planar member 12a partially covers the substrate 3 to be mounted. In other words, the board stopper unit 12 is located on the downstream side of the component mounting position [P] (working operation position) in the board conveying direction and stops the board 3 in a plan view of the upper surface of the board receiving mechanism 20. Thus, the planar member 12a having a partially covering shape is provided. In this state, execution of a setup change operation for changing the arrangement of the receiving pins 25 in the substrate receiving mechanism 20 located below the substrate 3 is hindered. For this reason, in the present embodiment, during the setup change operation, the substrate stopper unit 12 is placed upstream of the substrate 3 so that the planar member 12a does not obstruct the execution of the setup change operation by covering the upper side of the substrate receiving mechanism 20. Position alignment is performed with reference to the rear end surface 3b on the side (see FIG. 7).

  Next, the configuration of the control system will be described with reference to FIG. The control unit 30 is a CPU, and controls various units described below by executing various programs stored in the storage unit 31 to cause the component mounting apparatus 1 to execute a component mounting operation. The storage unit 31 stores board type data 31a and reference position data 31b in addition to various programs and data used for component mounting operations. The board type data 31a is data indicating the size, such as the length and width of the board 3 to be mounted, for each of a plurality of board types. The reference position data 31b is derived from the board type data 31a, and is a target for moving the board stopper unit 12 in order to position the boards 3 of a plurality of board types having different sizes at the component mounting position [P]. This is data indicating a reference position (see reference positions [P1] and [P2] shown in FIGS. 6 and 7).

  The mechanism driving unit 32 is controlled by the control unit 30 to be a component mounting mechanism including the substrate transport mechanism 2, the substrate receiving mechanism 20, the Y-axis moving table 7, the X-axis moving table 8, and the mounting head 9, and the substrate stopper unit 12. Then, the stopper moving mechanism 14 is driven. Thereby, the component mounting operation for the board 3 is executed. The setup change control processing unit 33 controls the stopper moving mechanism 14 on the basis of the substrate type data 31a and the reference position data 31b stored in the storage unit 31 in advance, whereby a plurality of receiving pins 25 are provided in the substrate receiving mechanism 20. A process of aligning the substrate stopper unit 12 at a reference position for executing a setup change operation that changes the arrangement of the two according to the target substrate type is performed.

  In the present embodiment, the board stopper unit 12 partially covers the upper surface of the board receiving mechanism 20 in a plan view in a state where the board 3 is stopped on the downstream side of the component mounting position [P]. Since the planar member 12a has a shape, the substrate stopper unit 12 for aligning the substrate 3 in the setup change operation is arranged so that the flat member 12a does not hinder the execution of the setup change operation. The reference position (see the reference position [P2] shown in FIG. 7B) is set upstream of the component mounting position [P] in the board conveyance direction. When the board stopper unit 12 is not configured to cover the upper surface of the board receiving mechanism 20, the reference position for aligning the board 3 in the setup change operation is set downstream of the component mounting position [P]. You may make it set to. That is, in this case, the reference position set for stopping the board 3 in the component mounting operation and the reference position for stopping the board 3 for the setup change work coincide.

  The operation / input unit 34 is an input device such as a keyboard or a touch panel set on the display panel, and inputs control commands for driving the device and various data. The display unit 35 is a display device such as a liquid crystal panel, and the guidance screen at the time of operation input via the operation / input unit 34 displays various screens.

  Next, in the electronic component mounting apparatus for executing the electronic component mounting work for mounting the electronic component on the board, an electronic component mounting work execution method for executing work operations for a plurality of board types will be described with reference to FIG. This will be described with reference to FIG.

  First, FIG. 6A shows a state in which the replacement work for realizing the receiving state corresponding to the target substrate 3 is completed in the substrate receiving mechanism 20 provided on the mounting conveyor 2b. At this time, the board | substrate stopper unit 12 exists in the stand-by position set to the carrying-in conveyor 2a. When the component mounting operation is started, the board 3 to be mounted is carried into the carry-in conveyor 2a from the previous process device. Next, as shown in FIG. 6B, the stopper moving mechanism 14 is driven to move the board stopper unit 12 to the mounting conveyor 2b (arrow e), and the board 3 is positioned at the component mounting position [P]. The board stopper unit 12 is positioned at the reference position [P1] (component mounting reference position).

  In the process in which the substrate 3 carried into the mounting conveyor 2b moves downstream, the front end surface 3a of the substrate 3 abuts on the rear end surface 19b of the abutting member 19 as shown in FIG. The board 3 is correctly positioned at the component mounting position [P]. Then, after a predetermined number of substrates 3 of one substrate type are produced, a setup change operation for changing the arrangement of the receiving pins 25 for the next substrate type is executed.

  That is, as shown in FIG. 7A, the substrate stopper unit 12 is once moved to the standby position of the carry-in conveyor 2a (arrow f), and then as shown in FIG. 7B, a reference for changing the pin arrangement. The substrate stopper unit 12 is moved to position [P2] (reference position for execution of setup change) (arrow g). In this state, the substrate 3 is set at the component mounting position [P], and the rear end surface 3b of the substrate 3 is brought into contact with the front end surface 19c of the contact member 19 as shown in FIG. Thereby, the board | substrate 3 is aligned with the regular position in component mounting position [P].

  Then, an operation of changing the arrangement of the receiving pins 25 in the substrate receiving mechanism 20 is performed while observing the interference with the already mounted components by repeatedly attaching and detaching the substrate 3 thus aligned. At this time, as shown in FIG. 7D, since the planar member 12a of the board stopper unit 12 is located upstream of the component mounting position [P], the planar member 12a obstructs execution of the setup change operation. There is nothing to do.

  That is, in the above-described electronic component mounting work execution method, based on pre-stored board type data, in the case of the setup change work accompanying the board type switching executed after the work operation for one board type is completed. By controlling the stopper moving mechanism 14, the substrate stopper unit 12 is aligned with a reference position for executing a setup change operation in which the arrangement of the plurality of receiving pins 25 is changed according to the target substrate type. I have to. In the above-described changeover operation, the board stopper unit 12 is moved to the reference position [P2] set upstream of the component mounting position [P] in the board conveyance direction.

As described above, in the electronic component mounting apparatus and the electronic component mounting work execution method in the electronic component mounting apparatus shown in the present embodiment, the board stopper unit 12 that stops the board 3 at the component mounting position [P]. In the electronic component mounting apparatus provided with the stopper moving mechanism 14 that moves the substrate in the substrate transport direction to be positioned at an arbitrary position, one substrate type is targeted in the process of continuously performing work operations on a plurality of substrate types. When the setup change operation is performed after the work operation is completed, the stopper moving mechanism 14 is controlled based on the substrate type data stored in advance, and the arrangement of the plurality of support pins 25 is changed according to the substrate type. the reference position for performing setup change work of, so that the substrate is aligned stopper unit 12.

  Accordingly, a preparatory work for setting a reference position, such as actually positioning the board 3 by performing a board transfer operation, or separately preparing a position reference mark indicating the position of the board 3 at the component mounting position [P]. In a production mode in which a plurality of substrate types are to be worked on, it is possible to efficiently perform the work of rearranging the receiving pins accompanying the switching of the substrate types.

  In the above-described embodiment, the component mounting apparatus 1 having a function of performing the component mounting work is shown as the electronic component mounting apparatus for performing the component mounting work for mounting the electronic component on the board. The application of the invention is not limited to component mounting work. For example, a screen printing device that prints a paste for bonding components on a substrate, such as a device that has a configuration that requires a changeover operation when switching the substrate type, targeting a double-sided mounting substrate that has already mounted components on the lower surface. This is an application target of the present invention.

  The electronic component mounting apparatus according to the present invention and the electronic component mounting work execution method in the electronic component mounting apparatus are the work of rearranging the receiving pins accompanying the switching of the board types in a production mode in which a plurality of board types are the work targets. This is useful in the field of manufacturing a mounting board by mounting electronic components on a board.
