Description

[Technical Field]

[0001] The present invention relates to a component mounting apparatus that uses a mounting head to pick up components supplied from a tape feeder attached to a carriage and mounts them on a board. [Background technology]

[0002] Conventionally, there is known a component mounting apparatus that uses a mounting head to pick up components supplied from a tape feeder attached to a carriage and mount them on a board. A base of such a component mounting apparatus is provided with a carriage coupling unit for coupling the carriage (for example, see Patent Document 1 below). In the component mounting apparatus, by coupling a carriage to the carriage coupling unit, components can be supplied from the tape feeder attached to the carriage.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-152455 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, tape feeders are mounted in the mounting slot of a carriage, and only tape feeders that fit the structure of the mounting slot of that carriage can be used. Therefore, component mounting equipment manufacturers generally design newly developed tape feeders on the assumption that they will be compatible with the carriages used in existing component mounting equipment. On the other hand, component mounting equipment manufacturers sometimes commercialize new component mounting equipment that achieves significant performance improvements by using new carriages with completely redesigned mounting slot structures or new tape feeders. However, there is a problem in that these new tape feeders cannot be mounted on existing carriages and therefore cannot be used with existing component mounting equipment. In other words, there may be cases where the carriage (first carriage) of an existing component mounting equipment can be mounted with the existing tape feeder (type 1 tape feeder) but not with the new tape feeder (type 2 tape feeder), and the new carriage (second carriage) can be mounted with the second type tape feeder but not with the first type tape feeder. Furthermore, it is usually not possible to connect a new type of carriage that is different from the existing carriage to the base of an existing component mounting device. For this reason, an existing component mounting device that can connect to an existing carriage can only use the existing tape feeder attached to that existing carriage, and cannot use a new type of tape feeder.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a component mounting apparatus that can increase the types of tape feeders that can be used. [Means for solving the problem]

[0006] The component mounting device of the present invention comprises a base that can be connected to a first carriage that can be fitted with a first type tape feeder but cannot be fitted with a second type tape feeder that is a different type from the first type tape feeder, and a second carriage that can be fitted with the second type tape feeder but cannot be fitted with the first type tape feeder, and that has a carriage connection part that selectively connects either one of them; and a mounting head that is provided on the base and picks up components supplied from the first type tape feeder or the second type tape feeder and mounts them on a board positioned relative to the base, wherein the carriage connection part has a pair of carriage guide parts that guide a pair of guided parts that are provided on the first carriage and the second carriage, respectively, and the spacing between the pair of carriage guide parts of the carriage connection part is equal to the spacing between the pair of guided parts that are provided on the first carriage and the pair of guided parts that are provided on the second carriage. [Effects of the Invention]

[0007] According to the present invention, the types of tape feeders that can be used can be increased, thereby improving productivity. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a component mounting apparatus 1 according to an embodiment of the present invention. In Fig. 1, the component mounting apparatus 1 is an apparatus that performs a component mounting operation by mounting components onto a board KB carried in from an upstream apparatus and carrying it out to a downstream apparatus.

[0010] 1, component mounting apparatus 1 includes a main body 1A having various operating units mounted on a base 11, and a component supply unit 1B connected to base 11 to supply components. Component supply unit 1B is connected to both ends of base 11 in the Y direction. For ease of explanation, the direction in which board KB is carried in and out (left-right direction) is defined as the X direction, the horizontal direction (front-rear direction) perpendicular to the X direction is defined as the Y direction, and the up-down direction is defined as the Z direction. Furthermore, the far side in the Y direction as viewed from the end side of base 11 (the side toward center 11Z of base 11) is defined as the front, and the opposite side (the near side) is defined as the rear.

[0011] 1, main body 1A includes, in addition to base 11, board positioning unit 12, head movement mechanism 13, mounting head 14, head camera 15, and component camera 16. Board positioning unit 12 includes a pair of conveyors 12a arranged side by side in the Y direction and a pair of board clampers 12b arranged opposite each other in the Y direction. The pair of conveyors 12a transports board KB received from an upstream device in the X direction (to the right in the paper of FIG. 1) and positions it at a predetermined working position, and the pair of board clampers 12b clamps board KB positioned at the working position by sandwiching it from the Y direction.

[0012] The head moving mechanism 13 is equipped with two Y-axis tables 13a and one X-axis table 13b. The two Y-axis tables 13a are provided at the left and right ends of the base 11, extending in the Y direction. The X-axis table 13b is supported at both ends by the two Y-axis tables 13a, and the mounting head 14 is attached to the X-axis table 13b. The X-axis table 13b is driven to move in the Y direction by a drive mechanism (not shown) provided on the Y-axis table 13a, and the mounting head 14 is driven to move in the X direction by a drive mechanism (not shown) provided on the X-axis table 13b. The mounting head 14 is equipped with multiple nozzles (not shown) extending downward.

[0013] In Fig. 1, head camera 15 is attached to mounting head 14. Head camera 15 has an imaging field of view facing downward. Component cameras 16 are provided at two locations on base 11, sandwiching board positioning section 12 from the outside in the Y direction. Each component camera 16 has an imaging field of view facing upward.

[0014] 1, the component supply unit 1B includes a carriage 21 and a plurality of tape feeders 22 attached to the carriage 21. Each tape feeder 22 supplies a component to a component supply port 22K.

[0015] When component mounting apparatus 1 performs a component mounting operation to mount components on board KB, first, pair of conveyors 12a of board positioning unit 12 is operated to carry in board KB from an upstream device and position it at a predetermined work position. Once board KB is positioned, pair of board clampers 12b clamps board KB and fixes board KB to base 11. Once board KB is fixed to base 11, mounting head 14 moves above board KB, and head camera 15 captures an image of board KB to recognize it.

[0016] Once the head camera 15 captures an image of the board KB and recognizes it, the mounting head 14 moves to above the tape feeder 22 and uses a nozzle to pick up (suck) a component that the tape feeder 22 supplies to the component supply port 22K. Then, the picked-up component is moved above the board KB.

[0017] As the mounting head 14 moves the component picked up by the nozzle above the board KB, the component camera 16 captures an image of the component from below. After the mounting head 14 moves the component above the board KB, the mounting head 14 places the component picked up by the nozzle in a predetermined position on the board KB based on the recognition result of the board KB based on the image of the board KB captured by the head camera 15 and the recognition result of the component based on the image of the component captured by the component camera 16.

[0018] By repeating this operation, the mounting head 14 mounts components onto the board KB, and when the component mounting device 1 has mounted all of the components to be mounted onto the board KB, the pair of conveyors 12a of the board positioning unit 12 operates to transport the board KB to a downstream device, thereby completing the component mounting operation for one board KB.

[0019] In the component mounting apparatus 1 configured as above, in this embodiment, many types of tape feeders 22 can be used by selectively connecting different types of carriages 21 to the base 11. This will be explained below.

[0020] 1, left and right wall portions 11H facing each other in the X direction are provided at both ends in the Y direction of the base 11. The left and right wall portions 11H protrude outward in the Y direction of the base 11 (Y direction) and are positioned facing each other with a predetermined gap in the X direction (see also FIG. 2).

[0021] 2, the wall surfaces (wall surfaces extending along the XZ plane) corresponding to the base portions of the left and right wall portions 11H of the base 11 are the front wall surface 11V, and the wall surfaces (surfaces extending along the YZ plane) of the left and right wall portions 11H facing each other are the left and right side wall surfaces 11W. The space surrounded by the front wall surface 11V and the left and right side wall surfaces 11W is the cart insertion space 11S into which the cart 21 is inserted. A base-side connector 11C is provided on the front wall surface 11V of the base 11 (FIG. 2).

[0022] 2, 3, and 4, a carriage coupling section 30 to which the carriage 21 is coupled is provided on the left and right side wall surfaces 11W of the base 11. The carriage coupling section 30 is configured to include an X-direction guide 31 arranged on each of the left and right side wall surfaces 11W, a front cam member 32A and a rear cam member 32B as Z-direction guides, a Y-direction stopper 33, a push-up section 34, and a return spring 35.

[0023] 2 and 3, the X-direction guides 31 have shapes that protrude in opposing directions (X direction) from the side wall surfaces 11W of the left and right wall portions 11H, respectively, and the side surfaces extending along the YZ plane form guide surfaces 31M. The left and right X-direction guides 31 are guides that position the carriage 21 inserted into the carriage insertion space 11S in the left-right direction (X direction) by means of a pair of opposing guide surfaces 31M.

[0024] 3 and 4, the front cam member 32A and the rear cam member 32B that make up the Z-direction guide are aligned in the front-to-rear direction, with the rear cam member 32B located rearward and below the front cam member 32A. The front cam member 32A and the rear cam member 32B each have a horizontal cam surface 32H consisting of a horizontal upper surface, and an inclined cam surface 32K that is connected to the horizontal cam surface 32H and slopes downward toward the rear (FIG. 4). These horizontal cam surface 32H and inclined cam surface 32K serve as Z-direction guide surfaces in the Z-direction guide (front cam member 32A and rear cam member 32B).

[0025] 2, 3 and 4, the Y-direction stopper 33 is provided at a position diagonally above and in front of the front cam member 32A. The Y-direction stopper 33 has a stopper surface 33M (FIG. 4) parallel to the XZ plane facing rearward.

[0026] 2, 3, and 4, the left and right push-up portions 34 are provided in a lower region between the front cam member 32A and the rear cam member 32B. The push-up portions 34 include a cylinder tube 34a attached to the side wall surface 11W, and a piston 34b that moves forward and backward relative to the cylinder tube 34a in an upper region of the cylinder tube 34a.

[0027] 2, 3, and 4, the return spring 35 has its base end (front end) held by a spring holding block 36 attached to the side wall surface 11W, and its tip end (rear end) extends horizontally. A pad 37 is attached to the tip end of the return spring 35.

[0028] 5, 6A, and 6B, the cart 21 includes a car body 41 and a feeder base 42. The car body 41 is capable of moving on the floor by using a plurality of casters 41C provided on the bottom. A cart-side connector 21C is provided on the front of the car body 41.

[0029] 1, 5, 6A, and 6B, a plurality of tape feeders 22 are mounted in a line in the X direction on feeder base 42. Feeder base 42 is provided with a plurality of mounting slots at equal intervals in the X direction for mounting tape feeders 22, and tape feeders 22 that fit the structure of these mounting slots are mounted. Each tape feeder 22 pulls out carrier tape CT from a reel RL (FIG. 6A) or cassette CS (FIG. 6B) stored in storage section 41S (FIG. 5) of vehicle body 41, transports it forward, and supplies components to component supply port 22K.

[0030] In the present embodiment, the tape feeder 22 shown in Fig. 6A and the tape feeder 22 shown in Fig. 6B are different in type (configuration). Hereinafter, the tape feeder 22 shown in Fig. 6A will be referred to as a "first type tape feeder 22A," and the tape feeder 22 shown in Fig. 6B will be referred to as a "second type tape feeder 22B."

[0031] In the present embodiment, the types (configurations) of the dollies 21 shown in Fig. 6A and the dollies 21 shown in Fig. 6B are also different. The dolly 21 shown in Fig. 6A is a dolly 21 equipped with a mounting slot (first type mounting slot) structured to allow mounting of a first type tape feeder 22A but not a second type tape feeder 22B, and will be referred to as the "first dolly 21A" below. The dolly 21 shown in Fig. 6B is a dolly 21 equipped with a mounting slot (second type mounting slot) structured to allow mounting of a second type tape feeder 22B but not a first type tape feeder 22A, and will be referred to as the "second dolly 21B" below.

[0032] In this embodiment, the first type tape feeder 22A is configured to supply components to the component supply port 22K by unwinding the carrier tape CT from the reel RL around which the carrier tape CT is wound and transporting it. For this reason, a plurality of reels RL corresponding to a plurality of tape feeders 22 (first type tape feeders 22A) are stored in the storage section 41S of the first carriage 21A, lined up in the X direction (FIG. 6A).

[0033] In this embodiment, the second type tape feeder 22B is configured to supply components to the component supply port 22K by pulling out and transporting a roll RT of carrier tape CT (carrier tape CT not wound on a reel) from a cassette CS in which the roll RT of carrier tape CT is stored. For this reason, a plurality of cassettes CS (a plurality of rolls RT) corresponding to a plurality of tape feeders 22 (second type tape feeders 22B) are stored side by side in the X direction in the storage section 41S of the second carriage 21B (FIG. 6B).

[0034] In the present embodiment, as described above, the first-type tape feeder 22A is configured so that the carrier tape CT is supplied by a reel RL, and the second-type tape feeder 22B is configured so that the carrier tape CT is supplied by a cassette CS, but the supply mode of the carrier tape CT is not a factor that distinguishes the first-type tape feeder 22A from the second-type tape feeder 22B. The factor that distinguishes the first-type tape feeder 22A from the second-type tape feeder 22B is that it can be attached to either the first carriage 21A or the second carriage 21B but not the other. Therefore, the first-type tape feeder 22A may be configured so that the carrier tape CT is supplied from a cassette CS, and the second-type tape feeder 22B may be configured so that the carrier tape CT is supplied from a reel RL.

[0035] As shown in Figures 6A and 6B, both first carriage 21A and second carriage 21B are provided with two cam followers (front cam follower 43A and rear cam follower 43B) arranged in front and behind, and one roller 44, on each of the left and right sides of feeder base 42. Rear cam follower 43B is located rearward and below front cam follower 43A. Roller 44 is attached to protrusion 42T (see Figures 7 to 10) that protrudes downward from the center of feeder base 42, and is located between front cam follower 43A and rear cam follower 43B, in an area slightly below rear cam follower 43B.

[0036] In this embodiment, the positional relationships between the front cam followers 43A, the rear cam followers 43B, and the rollers 44 are consistent between the first carriage 21A and the second carriage 21B. This means that not only are the relative positional relationships between the front cam followers 43A, the rear cam followers 43B, and the rollers 44 consistent on the left and right side surfaces of the feeder base 42, but also that the intervals between the left and right front cam followers 43A, the intervals between the left and right rear cam followers 43B, and the intervals between the left and right rollers 44 are consistent. Note that the above "intervals" refer to the intervals in the width direction (X direction) of the carriage 21.

[0037] In this embodiment, the distance in the X direction between the left and right guide surfaces 31M of the left and right X-direction guides 31 provided on the carriage coupling portion 30 of the base 11 is slightly larger than the left and right width direction dimension of the feeder base 42 of the carriage 21. The distance between the left and right front cam followers 43A provided on each of the first carriage 21A and the second carriage 21B matches the distance in the X direction between the left and right front cam members 32A provided on the carriage coupling portion 30 of the base 11, and the distance between the left and right rear cam followers 43B matches the distance in the X direction between the left and right rear cam members 32B provided on the carriage coupling portion 30 of the base 11.

[0038] The first carriage 21A and the second carriage 21B configured as described above can be selectively coupled to the carriage coupling section 30 of the base 11. When coupling the carriage 21 to the carriage coupling section 30, whether the carriage 21 is the first carriage 21A or the second carriage 21B, the carriage 21 is first positioned behind the carriage insertion space 11S of the base 11 (FIGS. 7, 8, 9, and 10). Then, as the carriage 21 is inserted into the carriage insertion space 11S, the feeder base 42 is guided by the guide surfaces 31M of the left and right X-direction guides 31, so that the carriage 21 is accurately oriented in the Y direction, and the carriage 21 moves in the Y direction (toward the back of the base 11) while being positioned in the X direction with respect to the carriage insertion space 11S.

[0039] As the carriage 21 advances in the carriage insertion space 11S in the Y direction, the front cam follower 43A of the carriage 21 abuts against the inclined cam surface 32K of the front cam member 32A on the base 11 side, and the rear cam follower 43B abuts against the inclined cam surface 32K of the rear cam member 32B (FIGS. 11A and 11B). When the front cam follower 43A and the rear cam follower 43B abut against the inclined cam surface 32K of the front cam member 32A and the inclined cam surface 32K of the rear cam member 32B, respectively, the insertion of the carriage 21 into the carriage insertion space 11S is temporarily stopped, and then the push-up unit 34 is actuated to move the piston 34b diagonally forward and upward (advance) (FIGS. 11A → 12A and 11B → 12B). The actuation of the push-up unit 34 may be performed manually by an operator or automatically.

[0040] Piston 34b advanced by push-up unit 34 comes into contact with roller 44 provided on carriage 21, and roller 44 is pushed up obliquely upward and forward by push-up unit 34. When roller 44 is pushed up obliquely upward and forward, front cam follower 43A moves from inclined cam surface 32K to horizontal cam surface 32H of front cam member 32A and moves forward, and rear cam follower 43B moves from inclined cam surface 32K to horizontal cam surface 32H of rear cam member 32B and moves forward. When front cam follower 43A is pressed against stopper surface 33M (FIG. 4) of Y-direction stopper 33 provided obliquely upward and forward of front cam member 32A, further forward movement of carriage 21 is restricted, and carriage 21 becomes coupled to carriage coupling unit 30 (i.e., base 11) (FIGS. 13A and 13B).

[0041] When the carriage 21 is connected to the base 11 in this manner, the carriage 21 is positioned in the X direction by the X direction guide 31, and is positioned in the Z direction by the Z direction guides (front cam member 32A and rear cam member 32B). The carriage 21 is also positioned in the Y direction by the Y direction stopper 33, and the position of the component supply port 22K of each tape feeder 22 attached to the feeder base 42 of the carriage 21 is accurately identified.

[0042] In the process of positioning the carriage 21 on the base 11 as described above, the left and right Z-direction guides (left and right front cam members 32A and left and right rear cam members 32B) of the carriage connecting unit 30 guide the left and right front cam followers 43A and left and right rear cam followers 43B provided on both sides in the width direction (X direction) of the carriage 21 attached to the base 11. That is, in this embodiment, the left and right front cam members 32A and left and right rear cam members 32B of the carriage connecting unit 30 of the base 11 serve as carriage guide units that guide the left and right front cam followers 43A and left and right rear cam followers 43B, which are a pair of guided units provided on both sides in the width direction of the carriage 21 attached to the base 11.

[0043] In the process of coupling the carriage 21 (first carriage 21A or second carriage 21B) to the base 11 as described above, when the front cam follower 43A and the rear cam follower 43B each move forward on the horizontal cam surface 32H, the protrusion 42T of the feeder base 42 comes into contact with the pad 37 provided at the leading end (rear end) of the return spring 35 and compresses the return spring 35 (FIGS. 11A and 11B). As a result, a biasing force from the return spring 35 acts on the carriage 21 in a rearward direction (i.e., in the direction of removal from the base 11). Therefore, the push-up unit 34 maintains a state in which the roller 44 is pressed forward with a force that resists the biasing force of the return spring 35 that biases the carriage 21 rearward, thereby maintaining the state in which the carriage 21 is coupled to the base 11.

[0044] Furthermore, in the process of connecting carriage 21 (first carriage 21A or second carriage 21B) to base 11, carriage-side connector 21C is coupled with base-side connector 11C (FIG. 11A → FIG. 12A and FIG. 11B → FIG. 12B). This enables carriage 21 to exchange signals with a control device (not shown) on base 11 side and to receive power from base 11 side. Furthermore, component mounting apparatus 1 is able to pick up components supplied from tape feeder 22 (first type tape feeder 22A or second type tape feeder 22B) attached to carriage 21 using mounting head 14, and to mount the components on board KB positioned at the work position by board positioning unit 12.

[0045] In this way, in the component mounting device 1 of this embodiment, for the first type tape feeder 22A and the second type tape feeder 22B which are different types from each other, the first cart 21A which can be fitted with the first type tape feeder 22A but not the second type tape feeder 22B, and the second cart 21B which can be fitted with the second type tape feeder 22B but not the first type tape feeder 22A can be selectively connected to the cart connection section 30. More specifically, the bogie connection unit 30 is provided with a pair of bogie guide units (left and right front cam members 32A and left and right rear cam members 32B) that guide a pair of guided units (left and right front cam followers 43A and left and right rear cam followers 43B) provided on both sides of the width direction (X direction) of each of the first bogie 21A and the second bogie 21B, and since the widthwise spacing of the pair of guided units provided on the first bogie 21A and the forward spacing of the pair of guided units provided on the second bogie 21B are equal to each other, the first bogie 21A and the second bogie 21B can be selectively connected to the bogie connection unit 30.

[0046] As described above, in component mounting apparatus 1 in the present embodiment, first carriage 21A and second carriage 21B can be selectively connected to carriage connecting section 30, so that first type tape feeder 22A can be used by connecting first carriage 21A to carriage connecting section 30, and second type tape feeder 22B can be used by connecting second carriage 21B to carriage connecting section 30. Therefore, compared to conventional component mounting apparatuses in which different types of carriages 21, each equipped with different types of tape feeders 22, could not be connected to the same base 11, it is possible to increase the types of tape feeders 22 that can be used and improve productivity.

[0047] When removing the carriage 21 connected to the base 11 from the carriage insertion space 11S, the push-up portion 34 is operated to move the piston 34b diagonally downward and rearward (retract), thereby removing the force pressing the front cam follower 43A against the Y-direction stopper 33. The carriage 21 is then urged rearward by the urging force of the return spring 35, and the left and right cam followers (front cam follower 43A and rear cam follower 43B) move from the horizontal cam surfaces 32H of the left and right Z-direction guides (front cam member 32A and rear cam member 32B) via the inclined cam surfaces 32K, respectively, and then disengage from the left and right Z-direction guides (FIG. 12A → FIG. 11A and FIG. 12B → FIG. 11B). This separates the carriage 21 from the base 11, completing the removal of the carriage 21.

[0048] As explained above, in the component mounting device 1 of this embodiment, for the first type tape feeder 22A and the second type tape feeder 22B which are different types from each other, the first carriage 21A which can be fitted with the first type tape feeder 22A but not the second type tape feeder 22B, and the second carriage 21B which can be fitted with the second type tape feeder 22B but not the first type tape feeder 22A, can be selectively connected to the carriage connection part 30 of the base 11, so that when the first carriage 21A is connected to the carriage connection part 30, the first type tape feeder 22A can be used, and when the second carriage 21B is connected to the carriage connection part 30, the second type tape feeder 22B can be used, and therefore the types of tape feeders 22 that can be used can be increased.

[0049] Although the embodiments of the present invention have been described above, the present invention is not limited to those described above and various modifications are possible.
