Description

  The present invention relates to an electronic component mounting apparatus that takes out an electronic component from an electronic component supply device and mounts the electronic component on a printed circuit board.

  Electronic devices are becoming multifunctional, and the number of electronic components required is also increasing. These electronic components are mounted on a printed circuit board and incorporated into an electronic device. Therefore, the number and type of components that can be mounted on the printed circuit board in a certain time greatly affects the cost of the electronic device.

  “Patent Document 1” describes an apparatus for picking up an electronic component from a component supply device by a mounting head having a plurality of nozzles and mounting the electronic component on a printed circuit board. The mounting head is attached to a mover that can move in the x direction installed in a beam extending in the x direction (hereinafter referred to as x beam), and the x beam is installed in a beam extending in the y direction (hereinafter referred to as y beam). It is attached to a mover that can move in the y direction. Each mover is moved to a desired position by a linear motor or a pulse motor in accordance with a command from the host computer, and performs an operation of picking up or mounting a component.

  Further, in “Patent Document 1”, component supply devices are arranged on both sides of a printed circuit board, and component mounting heads are arranged on both sides of the printed circuit board correspondingly to increase the speed of component mounting. In addition, it is described that parts that are frequently used are distributed and arranged in the parts supply unit in order to prevent a reduction in efficiency when a large number of specific parts are used.

2006-286707

  In the technique described in “Patent Document 1”, it is described that parts that are frequently used are distributed in a part supply device to reduce the total mounting time. In this case, each of the mounting heads arranged on both sides of the printed circuit board mounts electronic components on one side of the printed circuit board. That is, each mounting head takes out an electronic component from a component supply device existing on one side of the electronic component mounting device, and mounts it on only one side of the printed circuit board. Then, electronic components are mounted on the entire surface of the printed board by two mounting heads arranged in opposite directions.

  In such an arrangement, the two mounting heads mount components on only one side of the printed circuit board and do not collide with each other. However, in this case, since each mounting head mounts an electronic component only on one side of the printed circuit board from a component supply device existing on one side, the degree of freedom is limited. Therefore, each of the two mounting heads is not only from one component supply device, but also from the other component supply device, and the electronic component is mounted on the other side of the printed circuit board. Is also possible. However, in this case, there is a risk that two mounting heads interfere and collide. The applicant of the present invention relates to a mechanism that prevents two mounting heads from colliding during operation, or an electronic component mounting apparatus that does not destroy the mounting head when the mounting heads collide during maintenance. I am applying.

  The component supply device is arranged on both sides of the electronic component mounting device, or the two mounting heads are configured to absorb the component from either component supply device and mount the electronic component on the printed circuit board. The mounting speed of electronic parts increases. However, if there are still many electronic parts to be mounted, it may be insufficient.

  If there are many electrical components to be mounted on the printed circuit board, installing multiple electronic component mounting devices in succession and sharing the electronic components to be mounted on each electronic component mounting device will increase the mounting speed of the electronic components on the printed circuit board. Become. On the other hand, depending on the type of printed circuit board, there may be a lot of electronic parts or a few. When there are few electronic components, it is possible to use a single electronic component mounting device, and when there are many electronic component mounting devices, two or more electronic component mounting devices may be used. Thus, it is necessary to change the number of electronic component mounting apparatuses used flexibly according to the specifications of the printed circuit board.

  When using a plurality of electronic component mounting apparatuses, it is necessary to smoothly place the printed circuit board between the electronic component mounting apparatuses. The printed circuit board is transported by a transport device in the electronic component mounting device. Then, the printed circuit board moves on the printed circuit board conveyor of the transport device. Accordingly, the vertical and horizontal positions of the printed circuit board conveyor in the plurality of electronic component mounting apparatuses must be accurately matched.

  Electronic component mounting devices are large and heavy. Therefore, when the electronic component mounting apparatus is installed in the line, the position of the printed circuit board conveyor must be accurately adjusted. Therefore, conventionally, much time has been required for this purpose. An object of the present invention is to realize a configuration in which the positions of printed circuit board conveyors of a plurality of electronic component mounting apparatuses are set in a short time and accurately when an electronic component mounting apparatus is added to a line and installed. is there.

I can do it.

  Hereinafter, the contents of the present invention will be described in detail using examples.

  FIG. 1 is a plan view of an electronic component mounting apparatus according to the present invention. In FIG. 1, two first electronic component mounting apparatuses 1000 and two second electronic component mounting apparatuses 2000 are installed in parallel. The y beam of the first electronic component mounting apparatus 1000 and the y beam of the second electronic component mounting apparatus 2000 are separated by a distance d. However, the first electronic component mounting apparatus 1000 and the second electronic component mounting apparatus 2000 are connected by the printed circuit board conveyor 7. The printed circuit board PR that has been mounted by the first electronic component mounting apparatus 1000 is sent to the second electronic component mounting apparatus 2000. For example, the first electronic component mounting apparatus 1000 mounts electronic components on the half of the printed circuit board PR, and the second electronic component mounting apparatus 2000 mounts electronic components on the remaining half of the printed circuit board PR. The speed of mounting the electronic component on the printed circuit board PR is twice as fast as when there is only one electronic component mounting apparatus. Moreover, if three electronic component mounting apparatuses are installed in parallel, the mounting speed of electronic components is tripled.

  In addition to this, the advantage of using a plurality of electronic component mounting devices is that the first electronic component mounting device 1000 and the second electronic component mounting device 2000 can change the types of electronic components mounted on the printed circuit board PR. This is a possible point. In the electronic component mounting apparatus, the mounting head picks up a specific number of electronic components and mounts a plurality of components on the printed circuit board PR. The mounting head 6 is provided with a plurality of nozzles, and the number of nozzles is selected according to the type of electronic component to be mounted. For example, when the electronic component is small, twelve nozzles are installed on the mounting head, and when the electronic component is large, six suction nozzles are installed. Therefore, when a large component and a small component are mixed, the mounting speed of the electronic component is reduced. If two electronic component mounting apparatuses are used, for example, only a small electronic component is mounted on the first electronic component mounting apparatus 1000 and only a large electronic component is mounted on the second electronic component mounting apparatus 2000. The mounting speed of electronic parts is improved.

  However, it is inefficient to use two electronic component mounting apparatuses when the number of electronic component mounting points on the printed circuit board PR is not large. In that case, for example, the efficiency may be improved as a whole when the second electronic component mounting apparatus 2000 is used on another line. In such a case, for example, the second electronic component mounting apparatus 2000 is removed from the line. Then, when the electronic component is mounted on the printed circuit board PR having a large number of mounting points of the electronic component, the second electronic component mounting device 2000 is again installed in the line.

  For example, when the second electronic component mounting apparatus 2000 is installed in a line, it is necessary to accurately match the positions of the printed board conveyor 7 in the vertical direction and the horizontal direction. However, the electronic component mounting apparatus has a large outer shape and a large weight. Therefore, it takes a lot of time to accurately match the position of the printed board conveyor 7 in the two electronic component mounting apparatuses. The present invention makes it easy to accurately align the vertical and horizontal positions of the printed circuit board conveyor 7 of a plurality of electronic component mounting apparatuses when additionally installing electronic component mounting apparatuses on a line, and You can save time.

  First, the operation of each electronic component mounting apparatus will be described using the first electronic component mounting apparatus 1000 as an example. In FIG. 1, the printed circuit board PR is placed on a rail-shaped printed circuit board conveyor 7, supplied to the electronic component mounting apparatus from the left direction, and positioned at the center of the electronic component mounting apparatus. The printed circuit board transport device 2 includes a printed circuit board conveyor 7, a drive device, and a positioning device. When the mounting of the electronic component on the printed circuit board PR is completed, the printed circuit board PR is discharged rightward and sent to the printed circuit board transport device 2 of the second electronic component mounting apparatus 2000.

  In FIG. 1, with the first electronic component mounting apparatus 1000, for example, half of the components are mounted on the printed circuit board PR, and then the printed circuit board PR is placed on the printed circuit board conveyor 7 and moves to the right in the drawing. Then, the printed circuit board PR is transported to and installed in a second electronic component mounting apparatus 2000 provided on the right side of the first electronic component mounting apparatus 1000. In the second electronic component mounting apparatus 2000, the remaining electronic components are placed. Are mounted in the same manner as the first electronic component mounting apparatus 1000.

  In FIG. 1, component supply devices 3 are arranged on the upper and lower sides of the first electronic component mounting apparatus 1000. The component supply device 3 includes a feeder base 3A and a component supply unit 3B. The feeder base 3A is attached to the main body of the electronic component mounting apparatus. The component supply unit 3B is composed of many tapes on which electronic components are installed. When the component placed on the tape is taken out by the suction nozzle 5 of the mounting head 6, the tape is fed and the next electronic component can be taken out.

  On both sides of the electronic component mounting apparatus, y beams 1A and 1B extending in the y direction are formed. Y movers 9 are installed on the left and right y beams 1A and 1B. Here, a stator is installed in the y beam 1A and the y beam 1B, and the stator and the y mover 9 form a linear motor. Therefore, by this linear motor, the y movable element 9 can freely move in the y direction on the y beams 1A and 1B. The left and right y movers 9 are provided with ends of x beams 4A and 4B extending in the x direction. An x mover 15 is installed in the x beams 4A and 4B. Here, a stator is installed in the x beam 4A and the x beam 4B, and the stator and the x mover 15 form a linear motor. Therefore, by this linear motor, the x mover 15 can freely move on the x beams 4A and 4B. The mounting head 6 is attached to the x mover 15.

  The y mover 9 moves on the y beams 1A and 1B by a linear motor in response to a command from the host computer. The x mover 15 moves on the x beams 4A and 4B by a linear motor in response to a command from the host computer. A linear encoder is attached to the y movable element 9 and the x movable element 15, and position information of each movable element is fed back to the servo system.

  A suction nozzle 5 for sucking parts is attached to the mounting head 6 in a circumferential shape. In this embodiment, twelve suction nozzles 5 are arranged circumferentially. These nozzles are rotated by a nozzle rotation motor, and the target electronic component is adsorbed to each nozzle.

  A substrate recognition camera 8 is installed in the mounting head 6, and a reference point of the printed circuit board PR when the mounting head 6 is moved above the substrate is recognized, and an electronic component is based on the reference point of the printed circuit board PR. Is mounted on the printed circuit board PR. These components of the mounting head 6 are covered with a head cover, and a bumper (not shown in FIG. 1) is installed outside the head cover. The bumper is set for the purpose of reducing the impact when two heads collide.

  FIG. 1 is a diagram in which two mounting heads 6 adsorb electronic components from the upper component supply unit 3B and the lower component supply unit 3A, respectively. In this state, the mounting head 6 can suck 12 parts by rotating the nozzle.

  A component recognition camera 10 is installed between the component supply device 3 and the printed circuit board PR. The imaging unit of the component recognition camera 10 is installed on the lower side in the drawing of FIG. 1 and recognizes the state of the electronic component sucked by the suction nozzle 5. The component recognition camera 10 can recognize the state of the electronic component sucked by 12 nozzles at a time. If the electronic component is mounted on the printed circuit board PR while there is an abnormality in the suction state of the electronic component, a mounting failure occurs. Therefore, when a component adsorption abnormality is discovered by the component recognition camera 10, the problematic component is dropped in the discharge box 16. Similarly, when the electronic component sucked by the mounting head 6 is defective, it is dropped into the discharge box 16. The discharge box 16 is installed on the side of the component recognition camera 10. Two component recognition cameras 10 are installed on both sides of the printed circuit board PR. This is for more quickly recognizing the suction state of the electronic component.

  In FIG. 1, the y mover 9 is integrated, but when divided into an inner mover 9B and an outer mover 9A, the inner mover 9B is shorter than the outer mover 9A. This is when the two mounting heads 6 take out components from the same component supply device 3 or when the two mounting heads 6 mount electronic components in an area overlapping the printed circuit board PR in the y direction. This is to prevent the y mover 9 from becoming a stopper. Conversely, since the y mover 9 does not act as a stopper, there is a risk that the two mounting heads 6 collide. Therefore, in the case of this configuration, it is necessary to provide a mechanism for preventing the collision between the two mounting heads. It should be noted that it is possible to adopt a mechanism in which the mounting heads do not overlap each other in the y direction of FIG. That is, in this case, the mounting head 6 on the lower side of the drawing cannot suck the electronic component from the component supply device 3 on the upper side of the drawing. In the case of such a mechanism, 9A and 9B of the y mover can be made the same length.

  In the first electronic component mounting apparatus 1000 and the second electronic component mounting apparatus 2000 in FIG. 1, the x beams 4A and 4B are supported by two y beams 1A and 1B. However, the x beams 4A and 4B do not need to be supported by two y beams, and the x beam can be supported by only one of the y beams if the intensity of the x beam permits. For example, the x beam 4A may be supported only by the y beam 1A, and the x beam 4B may be supported only by the y beam 1B.

  The operation of the electronic component mounting apparatus has been described above by taking the first electronic component mounting apparatus 1000 as an example, but the same applies to the second electronic component mounting apparatus 2000. In FIG. 1, only the first electronic component mounting apparatus 1000 and the second electronic component mounting apparatus 2000 are connected. However, depending on the case, the third electronic component mounting apparatus or the fourth electronic component mounting apparatus may be used. You may connect.

  The electronic component mounting apparatus shown in FIG. 1 has component supply devices 3 installed on both sides (up and down direction on the paper). The component supply device 3 operates integrally with the electronic component mounting device, but is independent as a device. After the electronic component mounting device is installed at a specific position, the component supply device 3 is installed on the electronic component mounting device. The present invention relates to positioning of electronic component mounting apparatuses.

  FIG. 2 is a plan view of the electronic component mounting apparatus with the component supply device 3 removed from the electronic component mounting apparatus. The plan view of the electronic component mounting apparatus in this state is substantially H-shaped, and the main components are a y beam, an x beam, a mounting head, a printed circuit board transport device, a component recognition camera, a discharge box, and the like. . In FIG. 2, the external size of the electronic component mounting apparatus is such that the diameter L in the y direction is 1700 mm and the diameter W in the x direction is 1400 mm.

  FIG. 3 is a side view of FIG. 2 viewed from the A direction. As shown in FIG. 3, the electronic component mounting apparatus of the present invention is divided into an upper frame 100 and a lower frame 200. The upper platform 100 and the lower platform 200 are connected by a vertical adjustment bolt 150. The vertical adjustment bolt 150 is for accurately aligning the vertical position of the printed circuit board conveyor 7 installed on the gantry 100 with respect to the printed circuit board conveyor 7 of the adjacent electronic component mounting apparatus.

  In FIG. 3, the essential mechanism as the electronic component mounting apparatus is installed on the upper base 100. The upper base 100 is provided with a y beam, an x beam, a mounting head attached to the x beam, a printed circuit board conveyor, and the like. On the other hand, the undercarriage 200 is provided with an electrical equipment including a CPU, a servo mechanism, a vacuum pump for operating a nozzle attached to the mounting head, and the like.

  In FIG. 3, the height HS of the lower base 200 is 600 mm, and the height HC of the printed circuit board conveyor 7 on which the printed circuit board PR in the upper base 100 is placed is 905 mm. The height HC of the printed board conveyor 7 on which the printed board PR is placed is defined as a standard height in the industry. When two electronic component mounting apparatuses are installed together to mount electronic components on the printed circuit board PR, HC must be accurately matched. In FIG. 3, the positions of the printed circuit board conveyor 7 in the y direction and the x direction need to be accurately matched.

  4 is a front view of the electronic component mounting apparatus of FIG. 2 as viewed from the B direction. The lower gantry 200 and the upper gantry 100 are connected by a vertical adjustment bolt 150. In the gantry 100 of FIG. 4, the printed circuit board conveyor 7 is installed in the x direction. A printed circuit board PR is placed on the printed circuit board conveyor 7. 4 has an x beam extending in the x direction, and a mounting head attached to the x beam is present. The other mechanisms installed on the upper base 100 and the lower base 200 are as described in FIG.

  In FIG. 3, the height of the printed circuit board conveyor 7 can be set to a predetermined value by setting the height of the entire electronic component mounting apparatus with the pedestal adjustment bolt 211. However, in FIG. 4 and the like, the weight of the entire electronic component mounting apparatus is 1700 kg, and it is not easy to locate the mechanical elements installed in such a large and heavy apparatus.

  On the other hand, in the electronic component mounting apparatus, the weight of the lower base 200 is 1000 kg, and the weight of the upper base 100 is 700 kg. In this embodiment, after the electronic component mounting apparatus is divided into the upper base 100 and the lower base 200 and the overall height setting of the entire electronic component mounting apparatus is performed by the pedestal adjustment bolts 211 attached to the lower base 200. The vertical height adjustment bolt 150 adjusts the height of the printed circuit board conveyor 7 installed on the gantry 100.

  The merit of the configuration according to the present invention is that the relatively small weight of the gantry 100 is moved in the vertical direction by the vertical adjustment bolt 150, so that the moving mechanism is small. Furthermore, since the vertical adjustment bolt 150 is present in a portion close to the printed circuit board conveyor 7 as compared with the pedestal adjustment bolt 211, the printed circuit board conveyor 7 can be positioned more accurately.

  In order to connect a plurality of electronic component mounting apparatuses, the printed circuit board conveyor 7 must be set not only in the height direction (z direction) but also in the horizontal direction (x direction and y direction in FIG. 4). Don't be. FIG. 5 shows a schematic diagram of a mechanism for accurately positioning the horizontal direction of the upper base 100 including the printed board conveyor 7.

  In FIG. 5, a reference plate 140 integrated with the lower base 200 extends upward from the lower base 200 with respect to the H-type upper base 110 that supports the mechanism installed on the upper base 100. The lower gantry 200 is fixed on a pedestal 210, and the position of the upper gantry 100 is adjusted with respect to the lower gantry 200 to align with the adjacent electronic component mounting device. Actually, since the reference plate 140 is integrated with the lower base 200, the position of the upper base 110 is adjusted with respect to the reference plate 140. The upper base 100 is moved by the x direction adjusting bolt 160 or the y direction adjusting bolt 170.

  FIG. 6 is an enlarged schematic view showing a portion C of FIG. In FIG. 5, the upper platform base 110 is moved in the x direction with respect to the reference plate 140 integrated with the lower platform 200 by the x direction adjusting bolt 160. Further, the upper frame base 110 is moved in the y direction with respect to the reference plate 140 integrated with the lower frame 200 by the y direction adjusting bolt 170. The upper frame base 110 slides on the upper frame support plate 180 supported by the vertical adjustment bolts 150 integrated with the lower frame 200.

  In FIG. 6, an adjustment hole 111 having a diameter φ1 is formed in the upper base 110. A position fixing plate 130 is installed so as to cover the adjustment hole 111. On the position fixing plate 130, a horizontal positioning bolt 120 is installed. Then, the upper frame 100 can move in the horizontal direction with respect to the lower frame 200 by the difference (φ1−φ2) between the diameter φ2 of the shaft 121 of the horizontal positioning bolt 120 and the diameter φ2 of the adjustment hole 111. .

  FIG. 7 is a diagram for explaining the above-described contents in more detail. 7 is a cross-sectional view taken along the line AA in FIG. In FIG. 7, the shaft 151 of the vertical adjustment bolt 150 is embedded in the lower base 200. Since the vertical adjustment bolt 150 supports the entire upper base, the diameter of the shaft 151 is large. By rotating the vertical adjustment bolt 150, the upper platform 100 is moved in the vertical direction with respect to the lower platform 200. Thus, the vertical position of the printed circuit board conveyor 7 is set accurately. After the vertical position is accurately determined, the nut 152 is tightened to fix the vertical position of the gantry 100.

  The vertical adjustment bolt 150 is fitted on the upper platform support plate 180. The upper frame support plate 180, together with the vertical adjustment bolt 150, supports the entire upper frame. When the vertical adjustment bolt 150 is fixed by the nut 152, the vertical adjustment bolt 150 and the upper frame support plate 180 are integrated with the lower frame 200.

  An upper frame base 110 is installed on the upper frame support plate 180. Main parts of an electronic component mounting apparatus such as an x beam, a y beam, a mounting head, and a transfer device 2 are installed on the upper base 110. An adjustment hole 111 having a diameter φ1 is formed in the upper base 110. A position fixing plate 130 is installed on the upper base 110 so as to cover the adjustment hole 111. A horizontal positioning bolt 120 is installed on the position fixing plate 130. The shaft 121 of the horizontal positioning bolt 120 is embedded in the upper platform support plate 180. Accordingly, the horizontal positioning bolt 120 is integrated with the lower mount 200 via the upper mount support plate 180 and the vertical adjustment bolt 150.

  A reference plate 140 that is integrated with the lower base 200 extends upward from the lower base 200. In FIG. 7, the reference plate 140 is integrated with the lower base 200 by the reference plate fixing bolt 141. It goes without saying that the reference plate 140 may be fixed to the lower base 200 by welding or the like. An x-direction adjusting bolt 160 is installed at substantially the same position as the upper base 110 with respect to the reference plate 140. By turning the x-direction adjusting bolt 160, the upper base 110 can be moved in the x direction. The upper surface of the upper frame support plate 180 and the lower surface of the upper frame base 110 form a sliding surface S.

  The upper platform 100 can move relative to the lower platform 200 by a difference φ1-φ2 between the diameter φ1 of the adjustment hole 111 formed in the upper platform base 110 and the diameter φ2 of the shaft 121 of the horizontal positioning bolt 120. Therefore, the extent to which the upper platform 100 is desired to be moved after the installation of the lower platform 200 can be determined by the setting of the diameter φ1 of the adjustment hole 111 and the diameter φ2 of the shaft 121 of the horizontal positioning bolt 120.

  The main purpose of horizontal positioning of the upper base 100 is to align the position of the printed board conveyor 7 with the printed board conveyor 7 of the adjacent electronic component mounting apparatus. After the position of the printed board conveyor 7 is accurately determined, the position of the upper platform 100 is fixed. This fixing is performed by tightening the horizontal positioning bolt 120. As a result, the upper frame base 110 and the upper frame support plate 180 are fixed, and the upper frame base 110 and the lower frame 200 are fixed via the vertical adjustment bolt 150. In FIG. 7, two horizontal positioning bolts 120 are installed, but both perform the same operation. The reason for installing two horizontal positioning bolts 120 is to further stabilize the horizontal position of the gantry 100.

  In FIG. 7, only the movement in the x direction in the portion C of FIG. 5 has been described. The adjustment in the y direction in part C of FIG. 5 is essentially the same as described in FIG. In FIG. 5, an adjustment mechanism in the x direction and the y direction is installed at each of the four corners of the upper base 110. The adjustment method at each corner is the same as that described with reference to FIG.

  As described with reference to FIG. 7, the x-direction adjusting bolt 160 or the y-direction adjusting bolt 170 acts to push the upper mount base 110 inward, but does not pull it out to the outside. In FIG. 7, when the upper base 110 is moved to the outside, for example, the x-direction adjusting bolt 160 in the portion D of FIG. 5 is pushed in, and the x-direction adjusting bolt 160 shown in FIG. Can be moved outward (to the left).

  As described above, by using the present invention, the position of the printed circuit board conveyor 7 can be accurately and efficiently set, so that the electronic component mounting apparatus is incorporated into or removed from the line. And production efficiency can be improved.

  In the first embodiment, the plurality of electronic component mounting apparatus main bodies are not mechanically connected, and only the alignment of the printed circuit board conveyors 7 is performed. On the other hand, when a plurality of electronic component mounting apparatuses are connected, the strength of each electronic component mounting apparatus increases as a result, and each electronic component mounting apparatus has advantages such as being strong against vibration. However, as in the prior art, when the electronic component mounting device is not divided vertically, but is integrated, the printed circuit board conveyor 7 can be aligned with each other while the main body is connected, and It was difficult to perform leveling in the vertical direction using the pedestal adjustment bolt.

  In the present invention, since the electronic component mounting apparatus is divided into upper and lower parts, only the lower base 200 is connected, and by finely adjusting the upper base 100, the printed circuit board conveyor 7 is utilized while taking advantage of the connection of a plurality of electronic component mounting apparatuses. Can be aligned.

  FIG. 8 shows an example in which two electronic component mounting apparatuses are connected in this embodiment. In FIG. 8, a first electronic component mounting apparatus 1000 and a second electronic component mounting apparatus 2000 are connected in the x direction. However, the only part that is connected is the lower base 200, and the upper base 100 is not connected to each other. For example, the base 200 of the second electronic component mounting device 2000 is connected to the base 200 of the first electronic component mounting device 1000 by the connecting plate 300 and the connecting bolt 310.

  After connecting the lower mounts 200 to each other, the upper mount 100 of the second electronic component mounting apparatus 2000 is connected to the printed circuit board conveyor 7 of the first electronic component mounting apparatus 1000 and the second electronic component 100 as described in the first embodiment. Adjustments are made in the vertical and horizontal directions so that the printed circuit board conveyor 7 of the component mounting apparatus 2000 is accurately aligned. According to the present embodiment, since only the upper base 100 needs to be adjusted on the fixed base 200 of the second electronic component mounting apparatus 2000, the entire second electronic component mounting apparatus 2000 can be finely adjusted. Compared with the case of moving, alignment can be performed much more easily and accurately.

  When connecting the lower bases 200 to each other, the lower bases 200 are not completely brought into contact with each other, but are connected by the connecting plate 300 after providing a slight gap, for example, the upper base 100 is horizontally You can take the margin of adjustment when adjusting. Of course, when the diameter of the upper platform 100 is slightly smaller than the diameter of the lower platform 200, the lower platforms 200 may be brought into contact with each other and connected.

  In FIG. 8, two electronic component mounting apparatuses are connected, but the same applies when three or more electronic component mounting apparatuses are connected.

  In the above embodiment, the coupling in the case where the electronic component mounting apparatus is operated in cooperation has been described. However, cooperating with a plurality of devices on the printed circuit board PR is not limited to mounting electronic components. For example, the reflow of solder installed on the printed circuit board PR may be performed after mounting electronic components. Even in such a case, the printed circuit board conveyor 7 of each apparatus may be aligned and operated continuously. Even in such a process, as described in the first embodiment, the electronic component mounting apparatus is divided into the upper base 100 and the lower base 200 and the position of the upper base 100 is adjusted to adjust the position of the printed board conveyor 7. By performing the above, the devices can be easily coupled to each other.
