Description

  The present invention relates to an electronic circuit component mounting machine or an electronic circuit component mounting system for mounting an electronic circuit component on a circuit board to assemble an electronic circuit.

An electronic circuit component mounting machine (hereinafter abbreviated as a mounting machine unless otherwise required) includes, for example, a substrate holding device that holds a circuit board and an electronic circuit component as described in Patent Document 1 below. Component supply device, a mounting device that receives an electronic circuit component from the component supply device and mounts it on a circuit board held by the substrate holding device, and a main body that holds the substrate holding device, the component supply device, and the mounting device And a frame. In addition, a plurality of such electronic circuit component mounting machines are arranged on a common base as a mounting module, and an electronic circuit component mounting system (hereinafter, particularly, movable with respect to the base in a direction perpendicular to the arrangement direction). Patent Document 1 below describes a mounting system when it is not necessary.
These mounting machines and mounting modules are configured to be capable of automatic operation and include an electric control device, and many of these electric control devices are often arranged in the bed of the main body frame. For example, a CPU box, a control box, a servo box, and the like are disposed in the bed, and these generate considerable heat as they operate. Conventionally, the air inside the bed is exhausted to the side, rear, or downward from the exhaust ports formed in the side wall, rear wall, bottom wall, etc. Heat was exhausted by ventilation. An example is described in Patent Document 2 below. In the mounting machine described in Patent Document 2, a controller that may malfunction due to overheating, a driver that generates a large amount of heat, and a transformer that generates electromagnetic waves and may adversely affect peripheral devices are respectively provided in the bed. It is described that they are arranged in separate controller rooms, driver rooms, and transformer rooms, and each room is equipped with a ventilator to exhaust heat by exhausting to the side.

However, the exhaust to the side or rear places restrictions on the installation location of the mounting machine. For example, when a mounting machine that exhausts to the side forms a line by arranging a plurality of mounting machines, it prevents the mounting machines from coming close to each other and shortening the length of the line. Further, the exhaust to the front gives an uncomfortable feeling to the operator, and the exhaust to the lower side is undesirable because it raises dust on the floor surface. Similar problems occur in the mounting module of the mounting system. Thus, there is still room for improvement in conventional mounting machines and mounting systems.
In view of the above circumstances, the present invention has been made with the object of obtaining a mounting machine or mounting system with excellent practicality, such as few restrictions on installation locations.

According to the present invention , (a) a substrate transport holding device that transports the circuit board in the transport direction and holds the circuit substrate stopped at the stop position, and (b) an electronic circuit provided on one side of the substrate transport holding device. A component supply device for supplying components; (c) a mounting device for receiving electronic circuit components from the component supply device and mounting the electronic circuit components on the circuit board held by the substrate transfer holding device at the stop position; and (d) the boards. A plurality of mounting modules including a transport holding device, a component supply device, and a main body frame that supports the mounting device are arranged in the transport direction on a base that is movably supported in a direction crossing the direction in which the plurality of mounting modules are arranged. The circuit board is directly transferred by each of the board transfer and holding devices, and each electronic circuit component is assigned to the circuit board. An electronic circuit component mounting machine to be worn, wherein the component supply device side, which is one side of the substrate transport holding device of the electronic circuit component mounting device, is the front side, and the other of the substrate transport holding device of the electronic circuit component mounting device One side is the back side, and the surface other than the front side, back side, top surface, and bottom surface of the electronic circuit component mounting machine is the side surface, each body frame of the plurality of mounting modules includes a bed, and exhausts air in the bed A bed air discharge device is provided on the back side, the base is provided with a base air discharge device on the back side for discharging air in the base, and the plurality of mounting modules are on the base; The back surface of the base in the base air discharge device side is fixed to be substantially the same surface, and on the back side of the electronic circuit component mounting machine, the bottom surfaces of the plurality of mounting modules The wheel is provided between the upper surfaces of the bases and is respectively provided on the lower surfaces of the plurality of mounting modules. The wheels are supported on the upper surface of the base, and the plurality of mounting modules are fixed on the base. A flat plate having a surface constituted by a region and a mounting region that are substantially the same size as the gap, blocking the gap and preventing the air discharged from the bed and the air discharged from the base from flowing into the gap. Can be removably attached to the back surface of the base .

  The inside of the bed that forms the lower part of the main body frame is a perfect space for storing the electric control device. However, if the electric control device is actually stored, it is inevitable that a large amount of heat is generated in the bed. . Some electrical control devices, such as controllers, are prone to malfunction when the temperature is high, so that it is necessary for the electrical control device itself to improve the exhaust heat performance of the bed. Furthermore, since the bed forms the basis of the main body frame, if the temperature of the bed itself increases, the thermal distortion of the main body frame increases, which causes a reduction in the mounting accuracy of the electronic circuit components of the mounting machine or mounting system. Therefore, improving the heat exhaustion property of the bed is an important problem for ensuring accuracy.

  In that respect, according to the present invention, the heat generated in the bed can be discharged to the outside of the mounting machine or the mounting system, the malfunction of the electric control device can be prevented, or the life can be extended. . In addition, since air containing a large amount of heat is discharged to the upper part of the main body frame through an exhaust passage extending in the vertical direction, the mounting machine or mounting system should be installed close to other mounting machines or mounting systems. As a result, the degree of freedom of layout in the factory is improved, and the work space can be effectively used. Further, since the air discharged upward has a small specific gravity, it gathers above the work space and can be easily exhausted to the outside of the work space, making it easy to maintain a good work environment.

The suction nozzle 86a has a component suction surface and a diameter of the background forming plate 92a larger than those of the suction nozzle 86b, and is used for mounting a large electronic circuit component.

  Although not shown, the nozzle holder 88a in the mounting head 60a is a moving device provided in the head main body, provided in the head main body so as to be movable in the axial direction and in the vertical direction and rotatable about its own axis. It is moved up and down and rotated by the lifting device and the rotating device. As shown in FIG. 5, the mounting head 60 b includes a rotating body 100 provided on the head main body 96 so as to be rotatable around a vertical rotation axis, and a rotating body rotation that rotates the rotating body 100 in both forward and reverse directions at an arbitrary angle.

As shown in FIG. 3, the reference mark imaging device 28 is mounted on the second X-axis slide 76 and moved together with the mounting head 60 by the head moving device 62.

  Most of the electric control device 32 is accommodated in the bed interior 118 of the bed 36, and a part is accommodated in the base 12 as will be described later. In the bed chamber 118, as shown in FIG. 6, 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, in order to facilitate understanding of the internal structure, a state in which the cover is removed is shown, but actually, the openings on both sides of the column support base 132 are closed.

  A fan 268 is provided in the column support base 132, and the air exhausted above the bed 36 is exhausted to the back surface of the mounting module 10. Since the air discharged to the back surface still has a considerable amount of heat, it flows upward in the exhaust passage 262. Therefore, heat can be discharged while suppressing heat from being discharged sideways or downward.

  As shown in FIG. 7, a plate 274 that closes the gap between the base 12 and the mounting module 10 is attached to the base 12 with bolts 272. The bolts 272 may be attached to the bolt holes for the transport bracket 1101 as shown in FIG. By attaching the plate, from the exhaust passage 262 formed by being installed in a state of being opposed to each other with a gap of a size that an operator cannot enter on the back of the mounting module row composed of the plurality of mounting modules 10. The flow of air entering the gap can be suppressed, and the exhaust heat efficiency can be increased. Here, the distance that the operator cannot enter means a distance of 0.5 m or less.

As shown in FIGS. 6 and 7, a fan is provided on the back surface of at least one of the mounting module 10 and the base 200. Also, as shown in FIG. 12, when the mounting module 10 and the base 200 are installed facing each other, the fan 268 is provided at a location facing each other. Thus, by making the fans 268 face each other, the discharged air can be directed upward without being directly blown against the mounting module 10 and the base 200 facing each other. Furthermore, it is more preferable that the fan 268 is provided obliquely upward as shown in FIG. In this way, by making it obliquely upward, it is possible to make the flow directed upward more effective.

As described above, a part of the electric control device 32 includes a vacuum pump 166 typically shown in FIG. 8 and a positioning and fixing device that positions and fixes the mounting module 10 at a predetermined position with respect to the base 12. It is housed in a base inner chamber 168 inside the base 12 together with various auxiliary machines required for operating the mounting module 10. For example, a CPU, a CPU box 170 containing a control panel, a control box 172, etc. are housed. Although these also generate heat with the operation, in this embodiment, as shown in FIG. 7, this heat is discharged to the exhaust passage 262 by a fan 264 provided on the back surface of the base 12. At this time, the pressure of the space 266 is lowered by the flow of air discharged from the fan 268, and the force lifts the air discharged from the fan 264. Then, the air discharged from the fan 268 and the air discharged from the fan 264 are exhausted upward together.
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.

  The base 12 supports two mounting modules 10 shown in FIG. These two mounting modules 10 are arranged close to each other so that the circuit board 57 can be directly transferred between the substrate transfer devices 20 of each mounting module 10 without using an intermediate substrate transfer device. Yes. For this reason, if work by an operator such as inspection or maintenance is required inside the mounting module 10, the work cannot be performed if the work is kept aligned at the operation position shown in FIG. Therefore, a guide rail 178 is provided on the base 12, and each mounting module 10 is provided with a plurality of wheels 180 (see FIGS. 6 and 7). Has been. If an auxiliary cart is used, the mounting module 10 can be removed from the base 12 and replaced with another mounting module 10 or rearranged. In FIG. 8, the two guide rails 178 at the center of the base 12 and the supporting members thereof are removed.

The base 12 shown in FIG. 8 supports two mounting modules 10, but as shown in FIG. 9, a base 184 that can support four mounting modules 10 is also prepared. In addition, it can be used instead of the base 12. The base 184 has a high space efficiency because of the high degree of freedom of space utilization in the base inner chamber 186. As shown in FIG. 9, the transformer 190 installed outside the base 12 also has a CPU box 192 and a control. Along with the box 194, it can be stored in the base inner chamber 186. Even in the base 184, exhaust is performed upward.
Further, the mounting module is not limited to the size shown in FIG. 1, 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.

  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 the present embodiment, this is applied to both the bed 36 and the base 12. This is because moderate 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.
