Description

  The present invention relates to a carriage positioning mechanism of a component mounting apparatus that positions a position to be positioned of a carriage in a height direction when the carriage is coupled to a component mounting apparatus such as a component mounting apparatus, a printing apparatus, or an inspection apparatus. is there.

  Conventionally, among component mounting devices such as component mounting devices, printing devices, and inspection devices, it is possible to couple a cart equipped with a replacement carriage for a parts feeder or a personal computer for operation diagnosis of a component mounting device. What can be done is known. In such a cart, when coupled to the component mounting apparatus, positioning in the height direction is performed so that the height of the positioning target portion on the cart side matches the reference height on the component mounting apparatus side. For example, when a carriage equipped with a feeder base to which a plurality of parts feeders are attached is coupled to a component mounting apparatus, the feeder base is configured to be movable up and down with respect to a vehicle body portion provided with wheels. After positioning in the front-rear direction with respect to the component mounting apparatus, the feeder base is raised, and a part of the feeder base is brought into contact with the reference member on the component mounting apparatus side from below.

Further, in many of such carts, power for operating a device on the cart side (part feeder, personal computer, etc.) is taken from a power source provided on the component mounting device side. In this case, it is necessary for an operator to attach and detach (remove / remove) the connector on the cart side and the connector on the component mounting device side when connecting and separating the cart to the component mounting device. Since it is cumbersome, there is known one in which both the connectors are fitted when the positioning target portion is raised by the above-described carriage positioning mechanism and pressed against the reference member on the component mounting apparatus side (Patent Document 1). .

When 9) is operated, the control device 72 drives the pneumatic cylinder control valve 71 to extend the pneumatic cylinder 63 (arrow B shown in FIG. 13).

  When the pneumatic cylinder 63 is extended, the swinging member 61 swings upward in the upper and lower surfaces around the right front protrusion 51 (arrow C shown in FIG. 13), and the upper surface of the recess 61a is moved to the right lever member. It abuts from below on a protrusion 39 provided on 38 and pushes it upward. Then, the right lever member 38 abuts the claw portion 38a on the right claw portion locking member 53 from above and uses the abutment surface as a fulcrum, and the right front cam follower 37 is a cam of the right front cam member 52. Swing upward while rolling on the surface. On the other hand, the left lever member 38 connected to the right lever member 38 via the connecting shaft 36 also makes its claw portion 38a abut against the left claw portion locking member 53 from above and uses the abutment surface as a fulcrum. The left front cam follower 37 swings upward while rolling on the cam surface of the left front cam member 52.

  Accordingly, the left and right front cam followers 37 roll from the ascending slope surface 52a of the left and right front cam members 52 to the horizontal positioning surface 52b, whereby the connecting shaft 36 maintains the horizontal state and the cam surfaces of the left and right cam members 52 are maintained. It moves forward as a whole along the shape. Specifically, the connecting shaft 36 moves upward while the left and right front cam followers 37 are rolling on the ascending slope surface 52a of the left and right front cam members 52, and the left and right front cam followers 37 are left and right. While moving on the positioning surface 52b of the front cam member 52, the front cam member 52 moves forward in the horizontal direction.

  When the connecting shaft 36 moves forward as a whole in this way, the feeder base 35 supporting the connecting shaft 36 is also pulled by the connecting shaft 36 and moves forward. During this time, the left and right rear cam followers 41 move to the left and right rear. Since it rolls from the up-gradient surface 55a of the cam member 55 to the horizontal positioning surface 55b, the feeder base 35 moves to the front as a whole while maintaining the horizontal posture as a whole. While the feeder base 35 is moving forward as a whole, the vehicle body 22 connected to the feeder base 35 via the vertical support column 28 also moves forward while rolling the wheels 24 on the floor surface. Since the base 35 is movable up and down with respect to the vehicle body portion 22 via the vertical support column 28, the feeder base 35 moves upward with respect to the vehicle body portion 22 while moving forward.

  Left and right stoppers 64 (see FIGS. 7 and 13) are provided on the upper surfaces of the left side support member 13 and the right side support member 14, respectively, and the left and right front cam followers 37 abut against the left and right stoppers 64 from the rear. Then, positioning of the feeder base 35 in the front-rear direction with respect to the carriage coupling portion 15 is performed. At this time, the four cam followers (left and right front cam followers 37 and left and right rear cam followers 41) provided on the feeder base 35 are replaced with four cam members (left and right front cam members 52 and left and right rear cams) provided on the component mounting apparatus 1. The feeder base 35 is placed on the positioning surfaces 52b and 55b of the member 55), and the feeder base 35 is coupled to the component mounting apparatus 1 while being positioned in the height direction with respect to the component mounting apparatus 1. In the state where the feeder base 35 is coupled to the component mounting apparatus 1, the left and right front cam followers 37 are pressed against the left and right stoppers 64 by the pneumatic cylinder 63, so that the cam followers 37 and 41 of the feeder base 35 are There is no fear that the coupling between the feeder base 35 and the component mounting apparatus 1 is released by rolling the cam surfaces of the cam members 52 and 55 in the opposite direction.

  Further, immediately before the coupling of the carriage 20 to the component mounting apparatus 1 is finished, the feeder base 35 is moved forward in the horizontal direction. By moving the feeder base 35 in the horizontal direction, the horizontal portion of the feeder base 35 is moved. The trolley-side connector 42 (FIG. 5) provided in 32 and the mounting device-side connector 65 (FIG. 7) provided in the component mounting apparatus 1 are fitted in the horizontal direction. When the cart-side connector 42 and the mounting device-side connector 65 are fitted, the power source on the component mounting device 1 side can be used as the power source of the device (for example, the parts feeder 8) provided on the cart 20 side.

The cart positioning mechanism of the component mounting apparatus 1 according to the present embodiment performs positioning in the height direction of the feeder base 35 that is a positioning target portion of the cart 20 when the cart 20 is coupled to the component mounting apparatus 1. The cam followers 37 and 41 provided on the feeder base 35 so as to be rotatable about a horizontal axis are provided in the component mounting apparatus 1, and the ascending slope is in contact with the cam followers 37 and 41 when the carriage 20 is brought close to the component mounting apparatus 1. Cam members 52 and 55 having horizontal positioning surfaces 52b and 55b connected to the surfaces 52a and 55a and the up-gradient surfaces 52a and 55a are provided in the component mounting apparatus 1. After abutting on 52a and 55a, the feeder base 35 is pushed up to the component mounting apparatus 1 side, and the cam followers 37 and 41 are cam portions. A pneumatic cylinder 63 that rolls from the up-gradient surfaces 52a and 55a of the 52 and 55 to the positioning surfaces 52b and 55b and places the feeder base 35 on the positioning surfaces 52b and 55b of the cam members 52 and 55; It has become.

  In the cart positioning mechanism configured as described above, the cam followers 37 and 41 attached to the feeder base 35 which is the positioning target portion of the cart 20 resists the force of lowering the up-gradient surfaces 52a and 55a of the cam members 52 and 55. Since the operation of pushing up the cart 20 is performed by the pneumatic cylinder 63 as an actuator, the operator can easily perform the operation of coupling the cart 20 to the component mounting apparatus 1.

  Further, since the pneumatic cylinder 63 is provided not on the carriage 20 side but on the component mounting apparatus 1 side, it is not necessary to provide the pneumatic cylinder 63 for each carriage 20, and the manufacturing cost can be reduced.

  Further, the carriage positioning mechanism of the component mounting apparatus 1 according to the present embodiment is of a type in which the carriage-side connector 42 and the mounting apparatus-side connector 65 are fitted in the horizontal direction, and the feeder base 35 that is a positioning target portion of the carriage 20. When the cam followers 37 and 41 provided on the roller roll on the horizontal positioning surfaces 52b and 55b of the cam members 52 and 55, the connectors 42 and 65 are fitted using the fact that the feeder base 35 moves in the horizontal direction. I try to match. For this reason, it is difficult for dust and dust to enter both the connectors 42 and 65 on the cart 20 side and the component mounting apparatus 1 side, thereby preventing problems such as poor connection. Further, since both the connectors 42 and 65 are automatically coupled when positioning the feeder base 35 of the carriage 20 in the height direction, the operator bothers to bother the connectors 42 and 65 after coupling the carriage 20 to the component mounting apparatus 1. It is not necessary to perform the connection work, and work efficiency is improved accordingly.

  In order to separate the carriage 20 coupled to the component mounting apparatus 1 from the component mounting apparatus 1, the cylinder driving switch 75 is operated to contract the pneumatic cylinder 63, and the swing member 61 is moved to the arrow shown in FIG. After swinging in the direction opposite to B and returning to the initial position (the position shown in FIG. 13A), the left and right handles 21 may be pulled in the direction in which the carriage 20 separates from the component mounting apparatus 1. As a result, the four cam followers 37 and 41 on the carriage 20 side, which have been placed on the positioning surfaces 52b and 55b of the four cam members 52 and 55, roll from the positioning surfaces 52b and 55b to the downward slope surfaces 52a and 55a. Therefore, the cart 20 can be separated from the component mounting apparatus 1. Further, in this process, the feeder base 35 moves in the horizontal direction so as to move away from the component mounting apparatus 1, so that the cart side connector 42 is separated from the mounting apparatus side connector 65.

However, this is an example, and is not necessarily limited to four.

  In the above-described embodiment, the upward slope surface 52a of the front cam member 52 is an arc surface, and the upward slope surface 55a of the rear cam member 55 is an inclined surface. The shape of the upward surface) is not limited to an arc surface or an inclined surface. Moreover, the combination of the shape of the up-gradient surface in the front cam member 52 and the rear cam member 55 is not limited to the above-mentioned embodiment, and is arbitrary.

  Further, in the above-described embodiment, the pneumatic cylinder 63 swings the swing member 61, thereby pushing up the protrusion 39 provided on the feeder base 35 side, so that the cam followers 37, 41 are connected to the cam member 52, The pneumatic cylinder 63 can be changed to another actuator, and the cam followers 37 and 41 can be replaced by the cam members 52 and 55. The mechanism for rolling from the up-gradient surfaces 52a, 55a to the positioning surfaces 52b, 55b is not limited to that shown in the above-described embodiment.

  Further, in the above-described embodiment, the positioning target portion (feeder base 35) of the carriage 20 is configured to be movable up and down with respect to the vehicle body portion 22 of the carriage 20, but the positioning target portion of the carriage is not necessarily the body portion of the carriage. May not be movable up and down, and may be integrated with the vehicle body. In this case, when the positioning target portion of the carriage is pushed up toward the component mounting apparatus, the whole carriage is pushed up together with the vehicle body.
