Description

Technical area

[0001] The present invention relates to a component mounting apparatus that receives a component provided from a tape feeder mounted on a trolley by means of a mounting head and mounts the component on a substrate. Background of the invention

[0002] Generally, a component mounting apparatus is known that picks up a component supplied from a tape feeder mounted on a trolley with a mounting head and mounts the component on a substrate. A base of such a component mounting apparatus is provided with a trolley connecting portion for connecting to a trolley (see, for example, Patent Literature 1 below). In the component mounting apparatus, the component can be supplied from the tape feeder connected to the trolley by connecting the trolley to the trolley connecting portion.

[0003] PTL 1: Unexamined Japanese Patent Publication No. 2017-152455 Overview of the invention

[0004] Generally, the tape feeder is used by mounting it in a mounting slot of a dolly, and only a tape feeder that conforms to the structure of the dolly's mounting slot is used as a tape feeder that can be mounted in the dolly. Therefore, it is common for a component mounting equipment manufacturer to develop a newly developed tape feeder under the premise that the tape feeder matches a dolly used in an existing component mounting equipment. On the other hand, a component mounting equipment manufacturer may market a new component mounting equipment that has achieved significant performance improvement by using a new dolly with a new mounting slot structure or a novel tape feeder.One problem is that such a new type of tape feeder cannot be mounted on an existing trolley and therefore cannot be used in an existing component mounting device. That is, it may be the case that an existing tape feeder (first type of tape feeder) can be mounted on a trolley (first trolley) of an existing component mounting device, but a new type of tape feeder (second type of tape feeder) cannot; the second type of tape feeder can be mounted on a new trolley (second trolley), but the first type of tape feeder cannot be mounted. Furthermore, it is common that a new type of trolley that is different from the existing trolley cannot be connected to the base of the existing component mounting device.For this reason, in an existing component attachment device to which an existing trolley can be connected, only an existing tape feeder attached to the existing trolley can be used, and a new type of tape feeder cannot be used.

[0005] An object of the present invention is therefore to provide a component mounting apparatus which can increase the number of types of tape feeders which can be used.

[0006] A component mounting apparatus according to the present invention comprises: a first trolley on which a tape feeder of the first type can be mounted, but a tape feeder of the second type different from the type of the first tape feeder cannot be mounted, or a second trolley on which the tape feeder of the second type can be mounted, but the tape feeder of the first type cannot be mounted; a base including a trolley connecting portion that selectively connects to either the first trolley or the second trolley;and a mounting head provided on the base, which receives a component provided by the first type tape feeder mounted on the first trolley connected to the trolley connecting portion, or by the second type tape feeder mounted on the second trolley connected to the trolley connecting portion, and mounts the component on a substrate positioned with respect to the base;

[0007] According to the present invention, it is possible to improve productivity by increasing the number of types of usable tape feeders.

Description of the embodiment

[0008] An exemplary embodiment of the present invention will now be described with reference to the drawings. Fig. 1 shows a component mounting apparatus 1 according to an exemplary embodiment of the present invention. In Fig. 1, the component mounting apparatus 1 is an apparatus that performs a component mounting work in which a component is mounted on a substrate KB supplied from an upstream device and the component is conveyed to a downstream device.

[0009] In Fig. 1, the component mounting apparatus 1 includes a main body 1A having various operating units on the base 11, and a component supply unit 1B connected to the base 11 to supply a component. The component supply unit 1B is connected to both ends of the base 11 in the Y direction. For convenience, here, a loading and unloading direction (left-right direction) of the substrate KB is referred to as the X direction, a horizontal direction (front-back direction) orthogonal to the X direction is referred to as the Y direction, and a vertical direction is referred to as the Z direction. In the Y direction, the back side (center portion 11Z of the base 11) viewed from the end face of the base 11 is defined as the front side, and the opposite side (near side) is defined as the back side.

[0010] In Fig. 1, the main body 1A includes, in addition to the base 11, the substrate positioning unit 12, the head moving mechanism 13, the mounting head 14, the head camera 15, and the component camera 16. The substrate positioning unit 12 includes a pair of conveyors 12a arranged side by side in the Y direction and a pair of substrate clamps 12b provided facing the Y direction. The pair of conveyors 12a conveys the substrate KB received from the upstream device in the X direction (the right direction in Fig. 1) and positions the substrate KB at a predetermined working position, and the pair of substrate clamps 12b clamps the substrate KB positioned at the working position while sandwiching the substrate KB from the Y direction.

[0011] The head moving mechanism 13 includes two Y-axis tables 13a and one X-axis table 13b. The two Y-axis tables 13a are provided at the left and right end portions of the base 11 so as to extend in the Y direction. The two ends of the X-axis table 13b are supported by the two Y-axis tables 13a, and the mounting head 14 is mounted on the X-axis table 13b. The X-axis table 13b is moved in the Y direction by a drive mechanism (not shown) provided on the Y-axis table 13a, and the mounting head 14 is moved in the X direction by a drive mechanism (not shown) provided on the X-axis table 13b. The attachment head 14 includes a plurality of nozzles (not shown) extending downwardly.

[0012] In Fig. 1, the head camera 15 is attached to the mounting head 14. The head camera 15 has a downward-facing field of view. The component camera 16 is provided at two locations that sandwich the substrate positioning unit 12 from the outside in the Y direction on the base 11. Each component camera 16 has an upward-facing field of view.

[0013] In Fig. 1, the component supply unit 1B comprises a trolley 21 and a plurality of tape feeders 22 attached to the trolley 21. Each tape feeder 22 supplies a component to the component supply opening 22K.

[0014] In a case where the component mounting work of mounting the component on the substrate KB is performed by the component mounting apparatus 1, first, the pair of conveyors 12a of the substrate positioning unit 12 are operated to bring in the substrate KB from the upstream device and position the substrate KB at a predetermined work position. When the substrate KB is positioned, the pair of substrate clamps 12b clamp the substrate KB and fix the substrate KB on the base 11. When the substrate KB is fixed to the base 11, the mounting head 14 moves over the substrate KB, and the head camera 15 images the substrate KB to detect the substrate KB.

[0015] When the head camera 15 images and detects the substrate KB, the mounting head 14 moves over the tape feeder 22, and the component delivered by the tape feeder 22 to the component delivery port 22K is picked up (suctioned) by the nozzle. Then, the picked-up component is moved over the substrate KB.

[0016] When the mounting head 14 moves the component picked up by the nozzle over the substrate KB, the component camera 16 images the component from below. After moving the component over the substrate KB, the mounting head 14 mounts the component picked up by the nozzle at a predetermined position on the substrate KB based on the detection result of the substrate KB based on the image of the substrate KB captured by the head camera 15 and the detection result of the component based on the image of the component captured by the component camera 16.

[0017] When the components are mounted on the substrate KB by the mounting head 14 repeating such an operation, and then the component mounting apparatus 1 has mounted all the components to be mounted on the substrate KB, the pair of conveyors 12a of the substrate positioning unit 12 operates to discharge the substrate KB to the downstream device. Thus, the mounting of the components on the substrate KB is completed.

[0018] In the component mounting apparatus 1 having such a configuration, in the present exemplary embodiment, many types of tape feeders 22 can be used by selectively connecting different types of trolleys 21 to the base 11. This will be described below.

[0019] In Fig. 1, a left and a right wall section 11H are provided at both end sections of the base 11 in the Y direction, which face each other in the X direction. The left and right wall sections 11H protrude outward in the Y direction (Y direction) of the base 11 and are positioned so that they face each other at a predetermined distance in the X direction (see also Fig. 2).

[0020] In Fig. 2, the wall surfaces (wall surfaces extending along the XZ plane) corresponding to the root portions of the left and right wall sections 11H of the base 11 are front wall surfaces 11V, and the facing wall surfaces (surfaces extending along the YZ plane) of the left and right wall sections 11H are left and right side wall surfaces 11W. A space surrounded by the front wall surface 11V and the left and right side wall surfaces 11W is the trolley insertion space 11S into which the trolley 21 is inserted. On the front wall surface 11V of the base 11, the base-side connector 11C ( Fig. 2).

[0021] In Fig. 2, Fig. 3 and Fig. 4, the trolley connecting portions 30 to which the trolleys 21 are connected are provided on the left and right side wall surfaces 11W of the base 11. The trolley connecting portion 30 includes an X-direction guide 31 disposed on the left and right side wall surfaces 11W, respectively, a front cam member 32A and a rear cam member 32B as Z-direction guides, a Y-direction stopper 35, a push-up portion 34, and a return spring 35.

[0022] In Fig. 2 and Fig. 3, the X-direction guide 31 has a shape that protrudes in a direction (X direction) facing each other from each of the side wall surfaces 11W of the left and right wall portions 11H, with one side surface extending along the YZ plane being the guide surface 31M. The left and right X-direction guides 31 are guides for positioning the trolley 21 inserted into the trolley insertion space 11S in the left and right directions (X direction) through a pair of opposing guide surfaces 31M.

[0023] In Fig. 3 and Fig. 4, the front cam element 32A and the rear cam element 32B, which form the Z-direction guide, are arranged in the front-backward direction, with the rear cam element 32B located behind and below the front cam element 32A. Both the front cam element 32A and the rear cam element 32B have a horizontal cam surface 32H formed from a horizontal top surface and an inclined cam surface 32K connected to the horizontal cam surface 32H and sloping backward ( Fig. 4). The horizontal cam surface 32H and the inclined cam surface 32K are Z-direction guide surfaces (front cam element 32A and rear cam element 32B).

[0024] In Fig. 2, Fig. 3 and Fig. 4, the Y-direction stop 35 is arranged at a position obliquely in front of and above the front cam element 32A. The Y-direction stop 35 has a stop surface 33M ( Fig. 4), which is parallel to the XZ plane and points backwards.

[0025] In Fig. 2, Fig. 3 and Fig. 4, left and right push-up sections 34 are provided in a lower region between the front cam member 32A and the rear cam member 32B. The push-up section 34 includes a cylinder tube 34a fixed to the side wall surface 11W, and a piston 34b that is moved forward and backward relative to the cylinder tube 34a in an upper region of the cylinder tube 34a.

[0026] In Fig. 2, Fig. 3 and Fig. 4, a base end (front end) portion of the return spring 35 is held by a spring holding block 36 fixed to the side wall surface 11W, with one side of the front end (rear end) extending in a horizontal position. A support 37 is fixed to a front end of the return spring 35.

[0027] In Fig. 5, Fig. 6A and Fig. 6B, the trolley 21 includes a vehicle body 41 and a feeder base 42. The vehicle body 41 can move on a floor surface by means of a plurality of rollers 41C provided on the underside. The trolley connector 21C is located at the front of the vehicle body 41.

[0028] In Fig. 1, Fig. 5, Fig. 6A and Fig. 6B, a plurality of tape feeders 22 are mounted side by side in the X direction on the feeder base 42. The feeder base 42 is provided with a plurality of mounting slots for mounting the tape feeders 22 at equal intervals in the X direction, wherein the tape feeders 22 are mounted in a pattern corresponding to the mounting slots. Each tape feeder 22 draws the carrier tape CT from the reel RL ( Fig. 6A) or the cassette CS ( Fig. 6B) stored in the storage section 41S ( Fig. 5) of the vehicle body 41, the carrier belt CT transports forward and provides components for the component supply opening 22K.

[0029] In the present exemplary embodiment, the type (configuration) of the tape feeder 22 differs between that shown in Fig. 6A and the tape feed device 22 shown in Fig. 6B shown tape feed device 22. In the following, the Fig. 6A as “first type of tape feeder 22A” and the one shown in Fig. 6B is referred to as “second type of tape feeder 22B”.

[0030] In the present exemplary embodiment, the type (configuration) of the trolley 21 also differs between that shown in Fig. 6A and the trolley 21 shown in Fig. 6B shown trolley 21. The Fig. The trolley 21 shown in Fig. 6A is a trolley 21 with an attachment slot (first type of attachment slot) of a construction in which the first tape feeder 22A can be attached but the second tape feeder 22B cannot, and is hereinafter referred to as “first trolley 21A”. Fig. The trolley 21 shown in Fig. 6B is a trolley 21 having an attachment slot (second type attachment slot) of a structure to which the second tape feeder 22B can be attached but the first tape feeder 22A cannot, and which will be referred to as “second trolley 21B” hereinafter.

[0031] In the present exemplary embodiment, the first type tape feeder 22A is configured to supply components to the component supply opening 22K by pulling and transporting the carrier tape CT from the reel RL around which the carrier tape CT is wound. Therefore, in the storage section 41S of the first trolley 21A, a plurality of reels RL corresponding to the plurality of tape feeders 22 (first type tape feeders 22A) are stored side by side in the X direction ( Fig. 6A).

[0032] In the present exemplary embodiment, the second type tape supply device 22B is configured to supply components to the component supply opening 22K by pulling out and transporting the carrier tape CT from the cassette CS in which the reel body RT (the carrier tape CT not wound around a reel) of the carrier tape CT is stored. Therefore, in the storage section 41S of the second trolley 21B, a plurality of cassettes CS (a plurality of reel bodies RT) corresponding to the plurality of tape supply devices 22 (second type tape supply devices 22B) are stored side by side in the X direction ( Fig. 6B).

[0033] In the present exemplary embodiment, as described above, the first type of tape feeder 22A is configured to supply the carrier tape CT from the reel RL, and the second type of tape feeder 22B is configured to supply the carrier tape CT from the cassette CS. However, the manner of supplying the carrier tape CT is not a distinguishing feature between the first type of tape feeder 22A and the second type of tape feeder 22B. The distinguishing feature between the first type of tape feeder 22A and the second type of tape feeder 22B is that the tape feeders can be mounted on either the first carriage 21A or the second carriage 21B, but not on the other.Therefore, the first type tape feeder 22A may be in a form in which the carrier tape CT is supplied from the cassette CS, or the second type tape feeder 22B may be in a form in which the carrier tape CT is supplied from the reel RL.

[0034] As in Fig. 6A and Fig. 6B, in both the first carriage 21A and the second carriage 21B, two cam followers (front cam follower 43A and rear cam follower 43B) arranged forward and backward are provided, and a roller 44 is provided on the left and right side surfaces of the feeder base 42. The rear cam follower 43B is located behind and below the front cam follower 43A. The roller 44 is fixed to the projecting portion 42T (see Fig. 7 to 10) projecting downward from the central portion of the feeder base 42, and is located in an area between the front cam follower 43A and the rear cam follower 43B and slightly below the rear cam follower 43B.

[0035] In the present exemplary embodiment, the positional relationship between the front cam follower 43A, the rear cam follower 43B, and the roller 44 is the same between the first dolly 21A and the second dolly 21B. This means that the relative positional relationships between the front cam follower 43A, the rear cam follower 43B, and the roller 44 on the left and right side surfaces of the feeder base 42 are consistent, and the distance between the left and right front cam follower 43A, the distance between the left and right rear cam follower 43B, and the distance between the left and right roller 44 are also consistent. Note that the above "distance" refers to a distance in the width direction (X direction) of the dolly 21.

[0036] In the present exemplary embodiment, the X-direction distance between the left and right guide surfaces 31M of the left and right X-direction guides 31 provided in the trolley connecting portion 30 of the base 11 is slightly larger than the left and right width dimensions of the feeder base 42 of the trolley 21. The distance between the left and right front cam followers 43A included in the first trolley 21A and the second trolley 21B, respectively, agrees with the X-direction distance between the left and right front cam members 32A included in the trolley connecting portion 30 of the base 11, and the distance between the left and right rear cam followers 43B agrees with the X-direction distance between the left and right rear cam members 32B included in the trolley connecting portion 30 of the base 11.

[0037] The first trolley 21A and the second trolley 21B having such a configuration can be selectively connected to the trolley connecting portion 30 of the base 11. When the trolley 21 is connected to the trolley connecting portion 30, the trolley 21 is initially positioned behind the trolley insertion space 11S of the base 11 in both the case where the trolley 21 is the first trolley 21A and the case where the trolley 21 is the second trolley 21B ( Fig. 7, Fig. 8, Fig. 9 and Fig. 10). When the dolly 21 is then inserted into the dolly insertion space 11S, the feeder base 42 is guided by the guide surfaces 31M of the left and right X-direction guides 31, the posture of the dolly 21 is accurately aligned in the Y direction, and the dolly 21 moves forward in the Y direction (in the depth direction of the base 11) in a state where positioning in the X direction with respect to the dolly insertion space 11S is performed.

[0038] When the rolling carriage 21 moves in the Y direction into the rolling carriage insertion space 11S, the front cam follower 43A of the rolling carriage 21 abuts against the inclined cam surface 32K of the front cam member 32A on the side of the base 11, and the rear cam follower 43B abuts against the inclined cam surface 32K of the rear cam member 32B ( Fig. 11A and Fig. 11B). When the front cam follower 43A and the rear cam follower 43B come into contact with 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 trolley 21 into the insertion space 11S is temporarily stopped, whereupon the push-up section 34 is actuated to move the piston 34b forward and obliquely upward ( Fig. 11A → Fig. 12A and Fig. 11B → Fig. 12B). The lifting section 34 can be operated manually by an operator or automatically.

[0039] The piston 34b, which is pushed forward by the push-up section 34, abuts the roller 44 provided on the trolley 21, and the roller 44 is pushed forward and obliquely upward by the push-up section 34. When the roller 44 is pushed forward and obliquely upward, the front cam follower 43A rides on the horizontal cam surface 32H of the inclined cam surface 32K of the front cam member 32A and moves forward, and the rear cam follower 43B rides on the horizontal cam surface 32H of the inclined cam surface 32K of the rear cam member 32B and moves forward. When the front cam follower 43A abuts the stop surface 33M ( Fig. 4) of the Y-direction stopper 33 provided at the front and obliquely above the front cam member 32A, the further forward movement of the trolley 21 is restricted and the trolley 21 is connected to the connecting portion 30 of the trolley (ie, to the base 11) ( Fig. 13A and Fig. 13B).

[0040] In a state where the trolley 21 is connected to the base 11 in this way, the trolley 21 is positioned in the X direction by the X-direction guide 31 and in the Z direction by the Z-direction guide (front cam member 32A and rear cam member 32B). Furthermore, positioning in the Y direction is performed by the Y-direction stopper 33, and the position of the component supply opening 22K of each tape feeder 22 fixed to the feeder base 42 of the trolley 21 is precisely determined.

[0041] When positioning the dolly 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 dolly connecting portion 30 guide the left and right front cam followers 43A and the left and right rear cam followers 43B provided on both side surfaces in the width direction (X direction) of the dolly 21 mounted on the base 11.That is, in the present exemplary embodiment, the left and right front cam members 32A and the left and right rear cam members 32B included in the trolley connecting portion 30 of the base 11 are trolley guide portions that guide the left and right front cam followers 43A and the left and right rear cam followers 43B, which are a pair of guided portions provided on both side surfaces in the width direction of the trolley 21 mounted on the base 11.

[0042] When connecting the trolley 21 (first trolley 21A or second trolley 21B) to the base 11 as described above, when the front cam follower 43A and the rear cam follower 43B move forward on the horizontal cam surface 32H, the projecting portion 42T of the feeder base 42 abuts the support 37 provided at the front end (rear end) of the return spring 35 to compress the return spring 35 ( Fig. 11A and Fig. 11B). As a result, the trolley 21 is subjected to a biasing force biased rearward (i.e., in the removal direction from the base 11) by the return spring 35. Therefore, the push-up portion 34 maintains the state in which the return spring 35 pushes the roller 44 forward with a force that counteracts the biasing force pushing the trolley 21 rearward, thereby maintaining the state in which the trolley 21 is connected to the base 11.

[0043] In addition, when connecting the trolley 21 (first trolley 21A or second trolley 21B) to the base 11, the trolley-side connector 21C is coupled to the base-side connector 11C ( Fig. 11A → Fig. 12A and Fig. 11B → Fig. 12B). This allows the trolley 21 to exchange signals with a control device (not shown) on the base 11 side and to be supplied with power from the base 11 side. Furthermore, the component mounting apparatus 1 can receive a component supplied from the tape feeder 22 (first type tape feeder 22A or second type tape feeder 22B) mounted on the trolley 21 by the mounting head 14, and mount the component on the substrate KB positioned at the work position by the substrate positioning unit 12.

[0044] As described above, in the component mounting apparatus 1 according to the present exemplary embodiment, for the first-type tape feeder 22A and the second-type tape feeder 22B that are different from each other, the first trolley 21A on which the first-type tape feeder 22A can be mounted but the second-type tape feeder 22B cannot be mounted, and the second trolley 21B on which the second-type tape feeder 22B can be mounted but the first-type tape feeder 22A cannot be mounted, can be selectively connected to the trolley connecting portion 30.Specifically, the trolley connecting portion 30 includes a pair of trolley guide portions (left and right front cam members 32A and left and right rear cam members 32B) that guide a pair of guided portions (left and right front cam followers 43A and left and right rear cam followers 43B) provided on both side surfaces in the width direction (X direction) of each of the first trolley 21A and the second trolley 21B, wherein the pitch in the width direction of the pair of guided portions provided on the first trolley 21A is equal to the pitch in the front direction of the pair of guided portions provided on the second trolley 21B, whereby the first trolley 21A and the second trolley 21B can be selectively connected to the trolley connecting portion 30.

[0045] As described above, in the component mounting apparatus 1 according to the present exemplary embodiment, since the first trolley 21A and the second trolley 21B can be selectively connected to the trolley connecting section 30, the first type of tape feeder 22A can be used when the first trolley 21A is connected to the trolley connecting section 30, and the second type of tape feeder 22B can be used when the second trolley 21B is connected to the trolley connecting section 30. Therefore, the number of types of tape feeders 22 that can be used can be increased and productivity can be improved, compared with a conventional component mounting apparatus in which different types of trolleys 21 on which different types of tape feeders 22 are mounted cannot be connected to the same base 11.

[0046] When the rolling carriage 21 connected to the base 11 is removed from the rolling carriage insertion space 11S, the push-up section 34 is actuated to move (retract) the piston 34b rearward and obliquely downward, thereby canceling the force pressing the front cam follower 43A against the Y-direction stopper 35. Since the rolling carriage 21 is biased by the biasing force of the return spring 35 and moves rearward, the left and right cam followers (front cam follower 43A and rear cam follower 43B) are separated from the left and right Z-guides (front cam member 32A and rear cam member 32B) by the horizontal cam surfaces 32H of the left and right Z-direction guides via the inclined cam surfaces 32K ( Fig. 12A → Fig. 11A and Fig. 12B → Fig. 11B). This separates the trolley 21 from the base 11 and completes the removal of the trolley 21.

[0047] As described above, in the component mounting apparatus 1 according to the present exemplary embodiment, for the first-type tape feeder 22A and the second-type tape feeder 22B that are different from each other, a first trolley 21A on which the first-type tape feeder 22A can be mounted but the second-type tape feeder 22B cannot be mounted, and the second trolley 21B on which the second tape feeder 22B can be mounted but the first tape feeder 22A cannot be mounted can be selectively connected to the trolley connecting portion 30 of the base 11, wherein the first tape feeder 22A can be used by connecting the first trolley 21A to the trolley connecting portion 30, and the second tape feeder 22B can be used by connecting the second trolley 21B to the trolley connecting portion 30.Therefore, the number of types of usable tape feeders 22 can be increased.

[0048] Although the exemplary embodiment of the present invention has been described above, the present invention is not limited to the above exemplary embodiment, and various modifications and the like may be made. For example, in the exemplary embodiment described above, the guided portion includes the cam followers (front cam follower 43A and rear cam follower 43B) provided on the side surface of the trolley 21, and the guide portion of the trolley includes the cam members (front cam member 32A and rear cam member 32B) that guide the cam followers. However, the guided portion and the guide portion of the trolley do not necessarily have to be a combination of the cam members and the cam followers. Industrial applicability
