Having the mount 2 in the component mounting apparatus 1 configured as described above has the following technical significance. That is, in a production facility such as a component mounting facility, which is configured by arranging a plurality of facilities side by side, there is a strong demand for miniaturization of facility dimensions in order to improve area productivity. Therefore, it is required to reduce the overall width B of the apparatus as much as possible by reducing the width dimensions B1 and B2 of the first frame 21 and the second frame 22 shown in FIG. 3(b).

In the frame structure in which the first frame 21 and the second frame 22 having the small width dimensions B1 and B2 are arranged side by side, the other side is connected by the connecting member 24 to form a frame structure as shown in the present embodiment. By doing so, it is possible to increase the rigidity of the entire gantry 2 . Therefore, in the component mounting operation executed by driving the head moving mechanism 14, it is possible to ensure the rigidity of the pedestal 2 while miniaturizing the equipment size, thereby suppressing deterioration in the component mounting precision caused by the influence of vibration. can.

Next, referring to FIG. 4, the configuration and operation of the cutter 18 provided in the component supply section 5B will be described. A cutter 18 is provided below the mounting portion shown in FIG. 3(b). The cutter 18 has a function of cutting the carrier tape 9a discharged from the tape feeder 7 attached to the attachment portion.

As shown in FIG. 4A, the cutter 18 has a fixed blade 30 fixed inside the housing 18a and a movable blade 31 that moves forward and backward with respect to the fixed blade 30 by means of a cylinder 32. It has a configuration. A tape guide 11a for guiding the carrier tape 9a discharged from the tape feeder 7 of the component supply section 5B is inserted through the housing section 18a. An opening 19a that communicates with the duct 19 is provided in the bottom surface of the housing portion 18a.

As shown in FIG. 4B, when components are supplied by the tape feeder 7 in the component supply section 5B, the carrier tape 9a after the components are taken out is guided into the casing 18a by the tape guide 11a. In this state, when the cylinder 32 is driven to reciprocate the movable blade 31 (arrow a), the carrier tape 9a becomes tape dust 9a* cut into small pieces. Then, the tape dust 9a* falls into the duct 19 (arrow b) and is guided by the duct 19 to the collection section 11c provided on the reel carriage 11. As shown in FIG.

Next, referring to FIG. 5, the reel carriage connecting portion 34 provided on the other side of the gantry 2 will be described.

The reel carriage switch 33 is a mechanical switch having a probe 33a, and emits a detection signal when an object to be detected comes into contact with the probe 33a. That is, here, a switch for mechanically detecting that the reel carriage 11 has been connected is used as the detection section, and more reliable detection is ensured without erroneous detection.

As shown in FIG. 5(b), when the reel carriage 11 is brought closer to the frame 2 (arrow c) and the connection end portion 11b is fitted to the reel carriage connection portion 34, the approaching reel carriage 11 causes the probe 33a to move. pushed in. As a result, the reel carriage switch 33, which is a detector, mechanically detects that the reel carriage 11 has been connected, and this detection signal is transmitted to the control section 40 shown in FIG. The controller 40 controls the operation of the cutter 18 based on the detection result.

In the present embodiment, when the reel carriage switch 33, which is the detection section, detects that the reel carriage 11 is connected to the gantry 2, the operation of the cutter 18, which is the cutting section, is permitted. As a result, an unsafe state caused by the operation of the cutter 18 while the reel carriage 11 is removed from the frame 2, that is, the risk of an operator entering the frame 2 and touching the cutter 18 in operation can be avoided. It is designed to prevent Furthermore, there is the advantage that scattering of the tape dust 9a* due to the operation of the cutter 18 with the collecting portion 11c of the reel carriage 11 removed can be prevented.

The unsafe state described above can be improved by extending the length of the duct 19 that guides the tape dust 9a* cut by the cutter 18. This is not preferable because it lowers the workability at the time of product changeover work.

Next, the configuration of the control system of the component mounting apparatus 1 will be described with reference to FIG. In FIG. 6, the control unit 40 has a mounting processing unit 41, a recognition processing unit 42, a cutting processing unit 43, and a display processing unit 44 as internal processing functions.

FIG. As a result, the component mounting work of mounting the components taken out from the component supply section 5A and the component supply section 5B onto the board 4 positioned and held by the board transport conveyor 3 is performed.

In this component mounting work, the recognition processing unit 42 recognizes and processes the results of imaging by the component recognition camera 17 and board recognition camera 16 . In other words, the position of the substrate 4 is recognized by recognizing the imaging result of the substrate recognition camera 16 . Further, by recognizing the imaged result by the component recognition camera 17, the component held by the mounting head 15 can be identified and positional deviation can be detected. In component mounting by the mounting head 15, the head moving mechanism 14 is controlled in consideration of these recognition results.

The cutting processing section 43 controls the cutting operation by the cutter 18 by controlling the cutter driving section 46 . In this control, the operation of the cutter 18, which is the cutting section, is controlled based on the detection result of the reel carriage switch 33, which is the detecting section. That is, the operation of the cutter 18 is permitted when the reel carriage switch 33 detects that the reel carriage 11 is connected. As a result, the aforementioned inconvenience due to the operation of the cutter 18 in the state in which the reel carriage 11 is removed from the frame 2 is prevented. The display processing unit 44 displays on the display panel 26 that the reel carriage 11 is removed from the gantry 2 .
