  As shown in FIG. 6, most of the electric control device 32 is accommodated in a bed chamber 118 of the bed 36, and a part thereof is accommodated in the base 12 as will be described later. In the bed interior 118, a CPU box 120, a controller box 122, a servo box 124, and the like in which a CPU, a control panel, and a servo controller are housed are housed. Since the CPU, the control panel, and the servo controller all generate heat in accordance with the operation, each box 120, 122, and 124 is provided with an exhaust device (not shown), and the heated air inside is out of the box. That is, it is discharged into the bed chamber 118. A plurality of partition walls 126 are provided in the bed inner chamber 118 as necessary to ensure strength, etc., but these partition walls 126 are provided with openings so as not to hinder the air flow in the bed inner chamber 118. Has been.

  As shown in FIGS. 6 and 7, the air discharged into the bed inner chamber 118 is brought into bed by two fans 130 respectively provided at two exhaust ports 128 formed on the upper wall of the rear end of the bed 36. It is discharged above 36. A column support 132 is provided on the upper surface of the bed 36, and two rear columns 40 are raised from the column support 132. In FIG. 6, the side cover 133 (see FIG. 7) of the bed 36 and the column support base 132 is removed to facilitate understanding of the internal structure, and the back cover 134 (see FIG. 6) is removed in FIG. 7. However, in actuality, the opening to both sides and the rear of the column support base 132 is closed, and the rear opening of the rear column 40 is also closed. Inside the rear column 40, there is formed an exhaust passage 138 that communicates with each other through a communication port 136 formed in the upper wall of the column support base 132 and extends in the vertical direction.

  As described above, the beam 44 is supported by the front column 38 and the rear column 40, but the rear end portion of the beam 44 is wider than the middle portion and formed on the upper wall of the two rear columns 40. The communicating port 146 forms an exhaust passage 148 that communicates with each of the two exhaust passages 138. An exhaust port 152 is formed in the upper wall of the rear end of the beam 44, and the air in the exhaust passage 148 is exhausted upward by the fan 154 through the exhaust port 152.

  On the other hand, a linear motor 70 of the Y-axis direction moving device 66 is disposed inside the beam 44, and an X-axis slide moving device 78 is disposed below the beam 44. The linear motor 70 and the drive source (for example, a rotary electric motor) of the X-axis slide moving device 78 also generate heat with the operation. Air heated by these heats rises and is mainly received by the beam 44, and a part is received by the cover 46. The air received by the beam 44 is exhausted upward by a fan 156 provided at an exhaust port formed at a position adjacent to the rear end of the beam 44.

The air discharged upward by the fan 154 and the fan 156 is discharged from the exhaust port 162 provided in the cover 46 to the outside of the cover 46, that is, to the outside of the mounting module 10. At this time, the air received by the cover 46 is also discharged to the outside together with the air discharged by the fans 154 and 156.
In this embodiment, the fans 130 and 154, the exhaust passage 138, the exhaust port 162, and the like constitute an in-bed air exhaust device, and the fan 156 and the exhaust port 162 constitute an intra-crown air exhaust device.
Note that the interior of the rear column 40 is a portion that is also suitable for electrical wiring to the mounting device 26 and the like and a space for air piping. In this embodiment, both of the two rear columns 40 are exhaust passages and wirings. However, it is also possible to dedicate one of the two rear columns 40 for the exhaust passage and the other for the wiring and piping space.

As described above, a part of the electric control device 32 is positioned to fix the vacuum pump 166, the transformer 167, and the mounting module 10 that are representatively shown in FIG. It is housed in the base inner chamber 168 inside the base 12 together with various auxiliary machines necessary for the operation of the mounting module 10 including the fixing device. For example, a CPU, a CPU box 170 containing a control panel, a control box 172, etc. are housed. Although these also generate heat in accordance with the operation, in the present embodiment, this heat is discharged downward by a fan from an exhaust port (not shown) formed in the bottom wall of the base 12.
As the positioning and fixing device, for example, a positioning hole provided in the mounting module 10, a positioning pin held in the base 12 so as to be movable in the axial direction, and the axial movement of the positioning pin are inserted into the positioning hole. A combination with an air cylinder to be detached can be employed.

  In the above description, only the discharge of heated air has been described, and the intake of air for replenishment has not been described. However, in this embodiment, this is appropriate for both the bed 36 and the base 12. This is because gaps are formed, and a sufficient amount of air is sucked from these gaps. However, if necessary, an intake port can be provided, or an intake fan can be provided together with the intake port. If these are provided, the cooling performance of the bed 36 and the base 12 can be improved. Further, if an intake port or a fan is provided in the vicinity of a CPU or the like that is particularly susceptible to temperature, the purpose of cooling can be achieved more satisfactorily.

  As shown in FIG. 8, the base 12 includes four guide rails 174 on the upper surface. As shown in FIG. 9, each guide rail 174 has an upper flange 175, a lower flange 176, and a web 178 to form a groove shape, and each of the guide rails 174 has a base 12 with the groove-shaped openings facing each other. It is fixed to. On the other hand, a wheel group consisting of three or more (eight in the illustrated example) wheels 182 is attached to the wheel holding members 180 fixed to both sides of the bottom surface of the mounting module 10, and these wheels 182 serve as guides. It is inserted into the groove of the rail 174, and the movement in the vertical direction is restricted to a small amount, so that it can move substantially only in the longitudinal direction of the guide rail 174. Normally, the wheel 182 rolls on the lower flange 176, but when a rotational moment is applied to the mounting module 10 and the wheel 178 is lifted, the lift is restricted by the upper flange 175. Accordingly, even if the amount of the mounting module 10 to be pulled out increases and the center of gravity of the mounting module 10 moves out of the end of the guide rail 174, the mounting module 10 is only allowed to tilt at a minute allowable angle with respect to the base 12. Thus, it is possible to prevent the tilt from being larger than the allowable angle.

  Two pairs of guide rails 174 that form a pair with the above two extend over the entire length of the base 12. First, two sets of mounting modules 10 are mounted on one pair of these two pairs of guide rails 174. Is done. The wheels 182 of the two mounting modules 10 can be fitted into the grooves of the guide rails 174 from either end of the guide rails 174, but one mounting module 10 has the guide rails 174 first from the front side. The other mounting module 10 is mounted on the guide rail 174 from the back side first. Then, when the two mounting modules 10 reach a predetermined operating position with respect to the base 12, they are fixed to the base 12 by the positioning and fixing device described above. In this state, as shown in FIGS. 1 (a) and 1 (b), the back surface of the two mounting modules 10 is preferably a gap (150 mm or less, 100 mm or less, 80 mm or less that the operator cannot enter). It is further desirable that the back surfaces be in close contact with each other. However, in the present embodiment, as described above, the air heated by the heat generated inside the bed 36 is discharged upward from the upper surface of the module main body 18, and thus the two mounting modules 10. There is no problem even if the back surfaces of the two are brought close to each other. From the viewpoint of space efficiency, it is desirable that the gap is as small as possible, and it is particularly desirable that the back surfaces are in close contact with each other.

As described above, after two mounting modules 10 are mounted on one of the two pairs of guide rails 174, another two mounting modules 10 are mounted on another pair of guide rails 174 in the same manner. , Fixed in the operating position. In this state, four mounting modules 10 are mounted on the base 12 as shown in FIGS. 1 (a) and 1 (b), and the circuit board conveyors 54 and 56 of the two mounting modules 10 adjacent to each other side by side are connected to the circuit. The substrate 57 can be directly transferred.
On the other hand, if the mounting module 10 is kept in the operating position, an operator cannot enter between the two mounting modules 10 side by side. When work such as maintenance is required, the mounting module 10 is pulled forward as shown by a two-dot chain line in FIG. At this time, as described above, the mounting module 10 can be pulled out even when the center of gravity of the mounting module 10 comes out of the end of the guide rail 174, so that the work can be easily performed.

  Further, when any of the mounting modules 10 needs to be removed from the base 12 for rearrangement of the mounting modules 10 mounted on the base 12 or for replacement with another mounting module 10. 1 (c), the auxiliary carriage 183 is connected to the base 12 by a connecting device (not shown), and the mounting module 10 is moved onto the auxiliary carriage 183 to be removed from the base 12. it can. If there is sufficient space on both sides of the two-line mounting module row to connect the auxiliary carriage 183 to the base 12, both of the two back-to-back mounting modules 10 can be removed in the same manner. On the other hand, when the space on one side of the mounting module row is small and the auxiliary carriage 183 cannot be connected to the base 12, it is necessary to remove the mounting module 10 on the side where the space is small from the base 12. First, the mounting module 10 on the side with the larger space may be removed, and then the mounting module 10 on the side with the smaller space may be removed. In this way, the mounting module 10 on the side with the smaller space can also be removed from the base 12, so that the space on one side of the two-line mounting module row can be reduced, and the required floor space of the mounting system is reduced. I'll do it.

The base 12 shown in FIG. 8 supports four mounting modules 10, but a large base capable of supporting eight mounting modules 10 with a double width is also prepared. Alternatively, the base 12 can be used instead. Even in this large base, exhaust is performed downward.
The mounting module is not limited to the size shown in FIGS. 1 and 2, but a mounting module having a double width is also prepared, although illustration is omitted. This mounting module is suitable for use with a feeder 58 for supplying large electrical components and a tray-type component supply device.

  Another embodiment is shown in FIG. This embodiment is different from the above-described embodiment in that heat generated in the base inner chamber 202 of the base 200 is also exhausted upward. That is, the connection device 204 and the exhaust fan 206 are provided on the upper wall of the base 200 so that the air in the base inner chamber 202 is exhausted above the base 200. The air exhausted upward is exhausted upward by the exhaust port 218 and the fan 220 through the exhaust passage 216 in the column 214 together with the air exhausted from the bed 36 by the exhaust port 210 and the fan 212. The exhausted air is exhausted from the inside of the beam 44 to the outside of the mounting module 10 through the exhaust port 162 of the cover 46 together with the air exhausted by the fan 222 as in the above embodiment.

  The connection device 204 is provided to guide the air discharged from the base inner chamber 202 to the column 214 while allowing the mounting module 10 to move relative to the base 200. As shown in FIG. 11, the connecting device 204 includes a fixed joint portion 224 fixed to the module main body 18 and a movable joint member 226 provided on the base 200 side. The movable joint member 226 is held by the base 12 so as to be movable in the vertical direction via the guide device 228 and the drive device 230. The guide device 228 includes two guide rods 232 fixed to the movable joint member 226 and a guide bush 234 fixed to the base 12, and a piston 236 is fixed to an intermediate portion in the axial direction of each guide rod 232. On the other hand, a cylinder bore 238 is formed inside the guide bush 234, and an air cylinder 240 is constituted by the guide bush 234 having the cylinder bore 238 and the piston 236. The movable joint member 226 is biased upward by a compression coil spring 242 as a spring member, and the air cylinder 240 resists the biasing force of the compression coil spring 242 by supplying pressurized air to the upper chamber. Thus, the movable joint member 226 is a single acting cylinder that moves downward. In the present embodiment, the guide device 228 and the drive device 230 are integrally configured.

Normally, as shown in FIG. 11, the movable joint member 226 is brought into close contact with the fixed joint portion 224 by the urging force of the compression coil spring 242, and the connecting device 204 is in a connected state, and the base inner chamber 202 and the column 214 are placed inside. The exhaust passage 216 is in communication. Then, when it is necessary to move the mounting module 10 with respect to the base 200, the air cylinder 240 is operated, and the movable joint member 226 is separated from the fixed joint portion 224. The connecting device 204 is in a non-connected state, and in this state, the mounting module 10 can be moved with respect to the base 200 without any trouble.
In this embodiment, the connection device 204 and the fan 206 constitute a base air discharge device in cooperation with the bed air discharge device including the exhaust passage 216, the fan 220, the exhaust port 162, and the like.

  The base 200 is provided with a large upward opening similar to the base 12 so as to facilitate access to the internal device. However, when the mounting module 10 is in the operating position, this opening is the mounting module. The air is sucked from a narrow gap between the base 200 and the mounting module 10. However, if the upward opening is closed by a cover and an air suction port is formed at a desired location of the base 200, a desired air flow is generated in the base 200, or a filter is provided to enter the base 200. Intrusion of dust can be suppressed.
