Description

Technical Field

[0001] The present invention relates to a component loading device for picking up components from a carrier belt containing components and loading them onto a substrate. Background Technology

[0002] Conventionally, as a component supply unit used in a component mounting apparatus for mounting components on a substrate, a tape feeder is known to supply components to a designated component supply port by conveying a carrier tape containing components. The carrier tape is wound around a core of a reel that serves as a tape holder, and the transport, storage, and configuration of the carrier tape relative to the tape feeder are performed while it is wound on the reel.

[0003] In addition, it has been proposed to eliminate the belt holder such as the aforementioned reel, and instead transport, store, and configure the carrier tape relative to the belt feeder while it is wound into a disc-shaped roll in a coreless state (for example, Patent Document 1 below). In Patent Document 1, the roll is stored in a partially open box-shaped storage device, and the storage device containing the roll can be provided together with the belt feeder.

[0006] Patent Document 1: International Publication No. 2020 / 202737 Summary of the Invention

[0007] However, in the aforementioned Patent Document 1, the device for storing the roll of supplementary carrier tape (supplementary tape) is cantilevered to the end of the storage device for the roll of carrier tape (current tape feeder) being transported by the current tape feeder. Therefore, due to insufficient strength and rigidity of the storage device, it is difficult to cope with the large-scale production of the roll.

[0008] The purpose of this invention is to provide a component mounting device capable of handling the increasing size of rolls.

[0009] The component loading device of the present invention picks up components from a carrier tape containing components and loads them onto a substrate. The component loading device includes: a loading head for picking up components and loading them onto the substrate; a storage box having a first storage space for storing a roll of carrier tape and a first opening at the front for retrieving or storing the roll; a storage box assembly for assembling the storage box; a receiving box having a second storage space for storing a roll of carrier tape and a second opening at the front for retrieving or storing the roll, and storing a roll supplied from the storage box assembled to the storage box assembly; a receiving box assembly for assembling the receiving box; and a component supply unit that pulls a carrier tape from the roll of the receiving box assembled to the receiving box assembly and supplies a component to the loading head, and then pulls a carrier tape from the roll of the storage box assembled to the storage box assembly and supplies a component to the loading head.

[0010] According to the present invention, the large size of the roll can also be easily handled. Attached Figure Description

[0050] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 The diagram shows a side view of the main parts of a component mounting apparatus 1T according to an embodiment of the present invention. The component mounting apparatus 1T is an apparatus that repeatedly performs a series of component mounting operations on a substrate KB that is brought in from another device in an upstream process and a component mounting component BH that is brought out to another device in a downstream process. The component mounting apparatus 1T includes a component mounting apparatus main body 1A and a component supply unit 1B.

[0051] exist Figure 1 In this embodiment, the main body 1A of the component mounting device includes a base 11, a substrate transport section 12, a mounting head 13, and a head moving mechanism 14. The substrate transport section 12 is composed of a conveying mechanism that transports the substrate KB received from the upstream process device in a horizontal direction and positions it at a predetermined working position. In this embodiment, the transport direction of the substrate KB of the component mounting device 1T is defined as the X direction (lateral direction), the vertical direction is defined as the Z direction, and the direction orthogonal to the X and Z directions is defined as the Y direction (front-back direction).

[0052] exist Figure 1 In this device, the mounting head 13 has multiple downwardly extending nozzles 13N, which generate a vacuum attraction force from the adsorption component BH at the lower end of each nozzle 13N. The head moving mechanism 14 is, for example, an XY stage, and moves the mounting head 13 within the XY plane.

[0053] Figure 2 This is a side view of the component supply section 1B of the component mounting device 1T. Figure 3 This is a perspective view showing the cassette 22 of the component mounting device 1T together with the roll RT of the carrier CT stored in the cassette 22. Figure 4 This is an enlarged stereoscopic view of a portion of the carrier CT pulled out from the roll RT used in the component mounting device 1T. Figure 5 This is a side view showing the constituent elements of the component supply section 1B of the component mounting device 1T. Figure 1 as well as Figure 2 In the middle, the component supply unit 1B includes a trolley 21, a tape cassette 22, and a tape feeder 23. The tape cassette 22 can store the carrier CT roll RT (hereinafter referred to as roll RT) formed by winding the carrier CT into a disc shape in a coreless state (see also [reference]). Figure 3 That is, the cassette 22 processes the roll RT that is not wound onto the reel.

[0054] like Figure 4 ( Figure 4 yes Figure 3 As shown in the enlarged view of region AR, the carrier tape CT is composed of a baseband BT and a topband TT. Multiple upward-opening grooves PK are arranged in a row at equal intervals along the length of the baseband BT. A component BH is housed in each groove PK. The topband TT is attached to the upper surface of the baseband BT, and the component BH is sealed within a groove PK. Multiple feed holes SH are arranged in a row at equal intervals parallel to the row of grooves PK of the baseband BT.

[0055] exist Figure 1 as well as Figure 2 In this assembly, a pair of trolley guides 11G extending rearward and opposite each other in the X direction, and a pair of trolley retaining parts 11H also extending rearward and opposite each other in the X direction are provided on the base 11. The pair of trolley guides 11G are members that guide the left and right sides of the lower part of the trolley 21 when it is connected to the base 11. The pair of trolley retaining parts 11H are members that lift and support the left and right sides of the trolley 21 that have been guided by the trolley guides 11G and approached the base 11.

[0056] exist Figure 5 In the middle, a feeder base 31 is provided on the upper part of the trolley 21. A feeder mounting socket 31S for mounting a feeder 23 is provided on the upper surface of the feeder base 31 along the Y direction. The feeder 23 functions as a component supply unit for supplying component BH to the main body 1A of the component mounting device, and is achieved by sliding protrusions 23T (on the lower surface)... Figure 5 The feeder can slide onto the feeder mounting slot 31S of the feeder base 31, thereby enabling it to be mounted on the feeder base 31. Multiple feeder mounting slots 31S are arranged along the X direction on the feeder base 31. Therefore, multiple feeders 23 can be mounted in an arrangement along the X direction on the feeder base 31.

[0057] exist Figure 1 , Figure 2 as well as Figure 5 In the middle, the trolley 21 has a flat box assembly part 33 formed as a whole on the rear part (left side of each of these figures) of the trolley base 32 that moves freely on the floor FL. Figure 5 As shown, a pair of lower brackets 34 extending upwards are disposed opposite each other in the X direction at the middle of the front-rear direction on the trolley base 32. The two ends of the lower support rods 35 extending in the X direction are supported by these two lower brackets 34.

[0058] exist Figure 5In the feeder base 31, a pair of upper brackets 36 are disposed opposite each other along the X direction, extending downwards. These upper brackets 36 support the two ends of an upper support rod 37 extending along the X direction. The upper support rod 37 extends parallel to the lower support rod 35 at a position above it. Figure 5 ).

[0059] Figure 6 It's a 3D model with box 22. Figure 3 as well as Figure 6 In this device, the cartridge 22 includes a box-shaped storage section 41 and a gate 42, which serves as a restriction section, disposed within the storage section 41. The roll RT is stored in a longitudinal orientation within the storage section 41 of the cartridge 22. Here, "longitudinal orientation" refers to an orientation in which the central axis CJ of the disc-shaped roll RT is approximately horizontal.

[0060] In this embodiment, the tape cassette 22 is used in two ways. The first way is as a receiving portion of the roll RT of the carrier tape CT (current tape) currently being conveyed by the tape feeder 23, and it is assembled across the trolley base 32 and the cassette assembly 33. This tape cassette 22 used as a receiving portion of the roll RT of the current tape is hereinafter referred to as "receiving portion 22A" (…). Figure 2 as well as Figure 5 ).

[0061] The second use of the tape cassette 22 is as a storage device for the roll RT of the supplementary carrier tape CT (replenishment tape) used when the current tape component is exhausted, and it is mounted on the trolley base 32. The tape cassette 22 used as a storage device for the roll RT of the supplementary tape is hereinafter referred to as "storage cassette 22B" (…). Figure 2 as well as Figure 5 Thus, the receiving part 22A and the storage box 22B are box 22 with the same structure.

[0062] Each belt feeder 23 mounted on the feeder base 31 is a so-called automatic loading feeder, which feeds the belt from the belt inlet 23G located at the rear end. Figure 2 When the tip of the carrier CT is inserted, the situation is detected and the carrier CT is conveyed forward, and component BH is supplied to the designated component supply port 23K. At this time, the belt feeder 23 pulls out the carrier CT as the current belt from the roll RT in the receiving part 22A and conveys it.

[0063] The tip of a carrier tape CT (replenishment tape) pulled from the roll RT in the storage box 22B can be pre-inserted into the tape inlet 23G of the tape feeder 23 before the current tape component is exhausted. The tape feeder 23 starts conveying the replenishment tape when it detects that the tail end of the current tape has passed a predetermined position within the tape feeder 23. As a result, multiple carrier tapes CT are continuously conveyed without interruption, and component BH is supplied to the component mounting device 1T without component exhaustion. The tape feeder 23 is a component supply unit that pulls out a carrier tape CT from the roll RT of the receiving section 22A and supplies component BH to the mounting head 13, and then pulls out the carrier tape CT from the roll RT of the storage box 22B and supplies component BH to the mounting head 13.

[0064] When the component mounting device 1T performs component mounting operations, firstly, the substrate transport unit 12 operates to move the substrate KB from the outside and position it in the designated working position. After the substrate KB is positioned in the working position by the substrate transport unit 12, a mounting cycle is repeatedly executed, which is generated by the linkage between the operation of the belt feeder 23 supplying component BH to the component supply port 23K and the operation of the head moving mechanism 14 moving the mounting head 13.

[0065] In one mounting cycle, the mounting head 13 performs the following series of actions: after moving above the conveyor 23 and picking up (adopting) component BH using the nozzle 13N, it moves above the substrate KB to mount component BH onto the substrate KB. By repeatedly executing the mounting cycle, after all components BH to be mounted on the substrate KB have been mounted, the substrate transport unit 12 operates to move the substrate KB to the downstream process device. Thus, the component mounting operation for one substrate KB is completed.

[0066] Next, the structure of the cassette 22 used as the receiving part 22A or storage box 22B of the CT roll RT and the assembly steps to the trolley 21 will be described.

[0067] Figure 7 This is a side view of box 22. Figure 8 This is the main view of box 22. Figure 9 It is an exploded 3D view of box 22. Figure 10 This is a side view of the frame 43 included with box 22. Figure 6 , Figure 7 as well as Figure 8In this case, the cartridge 22 has a storage section 41 and a gate 42 provided within the storage section 41 as a restriction section. The storage section 41 has a U-shaped frame 43 and a pair of plate members (side plates 44) mounted on both sides of the frame 43 in the width direction. The space enclosed by the U-shaped frame 43 and the pair of side plates 44 becomes a storage space 41S for storing the cartridge RT. The U-shaped frame 43 has its opening facing forward, thus forming a front opening 41K at the front of the storage section 41.

[0068] Thus, in this embodiment, the storage section 41 has: a U-shaped frame 43 that surrounds the storage space 41S; and a pair of side plates 44 (plate members) that cover the sides of the storage space 41S and are fixed to the frame 43. The storage section 41 has a front opening 41K facing the outer periphery of the roll RT.

[0069] exist Figure 6 , Figure 8 as well as Figure 9 In the middle, frame 43 is composed of two frame members 43Z arranged along the width direction. For example... Figure 9 as well as Figure 10 As shown, the upper side of the horizontally facing frame 43 is designated as the upper frame portion 43a, and the lower side is designated as the lower frame portion 43b. An arc-shaped guide portion 43c is formed between the upper frame portion 43a and the lower frame portion 43b.

[0070] exist Figure 6 as well as Figure 8 In the configuration where the frame 43 is clamped by a pair of side plates 44, the upper part 43a of the frame 43 is located at the upper edge facing the side plates 44. The lower part 43b of the frame 43 is located at the lower edge facing the side plates 44. Figure 10 As shown, a gate guide portion 43g (guide portion) protruding towards the center side of an arc facing the frame 43 is formed on the inner peripheral surface of the guide portion 43c. A guide surface 43F that is inclined upwards and faces forward is provided on the lower surface of the front end of the upper part 43a of the frame.

[0071] exist Figure 6 as well as Figure 10 In the frame, starting from the front end, the upper part 43a of the frame has a locking groove 43M, a gripped part 45, and a lower support rod locking part 43P. The locking groove 43M is provided facing the upper surface of the upper part 43a of the frame and opens forward. The gripped part 45 is composed of a block-shaped component.

[0072] exist Figure 6 as well as Figure 10In the middle, three pin insertion parts 43S are arranged along the Y direction in the lower part 43b of the frame. In addition, an upper support rod engaging part 43Q is formed in the area between the two front pin insertion parts 43S and the rear pin insertion part 43S of the three pin insertion parts 43S.

[0073] exist Figure 5 In this assembly, three box-holding pins 33P are arranged in a row along the Y direction on the upper surface of the box assembly part 33. These three box-holding pins 33P constitute a box-holding pin row 33L. Multiple box-holding pin rows 33L are arranged along the X direction on the upper surface of the box assembly part 33.

[0074] exist Figure 5 In this configuration, a receiving part retaining pin 33Q is provided in front of each box retaining pin row 33L and coaxially with the box retaining pin row 33L. That is, multiple rows of three box retaining pins 33P (box retaining pin rows 33L) and one receiving part retaining pin 33Q are arranged in a row along the X direction on the upper surface of the box assembly part 33.

[0075] Figure 11 as well as Figure 12 This is a side sectional view of a portion of the component mounting device 1T. The receiving portion 22A is as follows: Figure 2 as well as Figure 12 As shown, the storage box 22B is assembled onto the trolley 21 with its top and bottom reversed, i.e., upside down. When the receiving part 22A is assembled onto the trolley 21, as... Figure 11 As shown, the lower support rod engaging portion 43P engages with the lower support rod 35, the upper support rod engaging portion 43Q engages with the upper support rod 37, and the engaging groove 43M engages with the receiving portion retaining pin 33Q. Thus, in this embodiment, one receiving portion retaining pin 33Q, the lower support rod 35, and the upper support rod 37 form a receiving portion assembly portion 38 (receiving portion assembly portion) for assembling the receiving portion 22A. The housing 22 includes a sub-mounting portion 43R (formed by the upper support rod engaging portion 43Q of the upper frame portion 43a and the lower frame portion 43b). Figure 10 as well as Figure 11 By assembling the sub-mounting part 43R to the receiving part assembly part 38, the tape box 22 is assembled as the receiving part 22A onto the component mounting device 1T. In this way, the receiving part assembly part 38 assembles the tape box 22 in an upside-down orientation.

[0076] Storage box 22B, as shown Figure 12The device is assembled onto the trolley 21 by inserting three storage box retaining pins 33P, which form a box retaining pin row 33L, into three pin insertion portions 43S located on the lower part 43b of the frame. Thus, in this embodiment, the box retaining pin row 33L (three storage box retaining pins 33P arranged in a row along the Y direction) becomes the storage box assembly part 39 (storage device assembly part) for assembling the storage box 22B. The box 22 has a main mounting part 43U (mounting part) formed by the lower part 43b of the frame. Figure 10 as well as Figure 12 By assembling the main mounting part 43U to the storage box assembly part 39, the belt box 22 is assembled as a storage box 22B onto the component mounting device 1T.

[0077] exist Figure 11 as well as Figure 12 In this assembly, the receiving part assembly section 38 assembles the receiving part 22A with its front opening 41K facing the storage box assembly section 39. Similarly, the storage box assembly section 39 assembles the storage box 22B with its front opening 41K facing the receiving part 22A assembled to the receiving part assembly section 38. Thus, with the front openings 41K of the receiving part 22A and the storage box 22B facing each other, the receiving part 22A and the storage box 22B are assembled onto the trolley 21. Therefore, the scroll RT stored in the storage box 22B can be moved towards the receiving part 22A.

[0078] Furthermore, the receiving part assembly part 38 assembles the receiving part 22A at a position lower than that of the storage box 22B assembled in the storage box assembly part 39. This allows for smooth movement of the roll RT from the storage box 22B to the receiving part 22A, and prevents the roll RT stored in the receiving part 22A from moving towards the storage box 22B.

[0079] Furthermore, the receiving section assembly section 38 assembles the receiving section 22A into an inclined posture that decreases as it moves away from the storage box assembly section 39. As a result, the movement of the roll RT from the storage box 22B to the receiving section 22A is smooth, and the movement of the roll RT stored in the receiving section 22A to the storage box 22B is prevented.

[0080] Figure 13 as well as Figure 14 This is a side sectional view of box 22. Figure 15 This is a side view of the gate 42 included with the housing 22. Figure 6 , Figure 13 as well as Figure 14 In this configuration, gate 42 is positioned within the storage space 41S of storage unit 41. Also, as... Figure 15As shown, the gate 42 is integrally J-shaped and has an arc-shaped sliding portion 51 and a gate front end portion 52 extending in a straight line from one end of the sliding portion 51. An operating rod 53 is connected to the sliding portion 51 and extends protruding outward toward the outer side (away from the center) of the arc-shaped sliding portion 51. The operating rod 53 is disposed protruding toward the rear of the storage portion 41.

[0081] exist Figure 6 , Figure 7 as well as Figure 8 In this design, a belt retaining portion 54 is provided at the front end of the gate 42 (the end of the gate front end portion 52). The belt retaining portion 54 is a plate-shaped portion extending along the extending direction of the gate front end portion 52. Two belt locking protrusions 55 extend protruding from the front end of the belt retaining portion 54, serving as feed hole engagement portions. These two belt locking protrusions 55 are arranged parallel to each other in a plane orthogonal to the width direction of the retaining portion 41.

[0082] The outer peripheral surface of the arc-shaped sliding part 51 of the gate 42 is guided by the aforementioned arc-shaped gate guide part 43g of the frame 43. When the operating lever 53 is operated, the gate 42 is guided by the gate guide part 43g and slides in the region inside the frame 43 along a rotation direction with an axis parallel to the X direction as the rotation axis.

[0083] The gate 42, at its front end 52, is positioned such that it extends vertically (Z-direction) at the front of the storage space 41S, thus closing the front opening 41K of the storage section 41 (first position). Figure 13 Furthermore, the gate 42 is positioned at its front end 52, extending along the front-rear direction (Y direction) below the storage space 41S, in an open position (second position) that opens the front opening 41K of the storage section 41. Figure 14 When the gate 42 is in the closed position, the roll RT in the storage space 41S cannot move out of the storage section 41 through the front opening 41K. However, when the gate 42 is in the open position, the roll RT in the storage space 41S can move out of the storage section 41 through the front opening 41K.

[0084] exist Figure 10 , Figure 13 as well as Figure 14 In the middle, an open-side limiting surface 43T is formed at the front end of the lower part 43b of the frame. An abutment surface 52T, serving as the end face of the front end 52 of the gate, is formed at the boundary between the sliding part 51 of the gate 42 and the front end 52 of the gate. Figure 13 When the operating lever 53 is moved from the lower position to the upper position, the gate 42 moves along... Figure 13 clockwise rotation ( Figure 13 → Figure 14After the contact surface 52T abuts against the open side limiting surface 43T, it is in the closed position. Figure 14 ).

Additionally... Figure 16G It is a cross-section of a portion of the casing 22 when the gate 42 is in the open position. Figure 14 The G-G section shown.

[0086] exist Figure 10 as well as Figure 14 In the middle, a closing-side limiting surface 43K is formed at the upper end (rear end) of the lower part 43b of the frame. When the operating lever 53 is moved from the upper position to the lower position, the gate 42 moves along... Figure 14 Counterclockwise rotation ( Figure 14 → Figure 13 After the operating lever 53 abuts against the closing side limiting surface 43K, it is in the closed position.

As a result, the gate 42 moves from the open position to the closed position, the front opening 41K of the storage section 41 is closed by the gate 42, and the roll RT is stored in the cassette 22. Figure 17B ).

[0088] On the other hand, when the roll RT stored in the cassette 22 is removed, the operating lever 53 is moved upward ( Figure 17C (See arrow N2 shown). As a result, the gate 42 moves from the closed position to the open position, the front opening 41K of the storage section 41 opens, and the scroll RT can be retrieved from the storage section 41. Figure 17C Arrow M2 as shown.

[0089] Thus, in this embodiment, the cassette 22, serving as a storage device, includes: a storage section 41 having a storage space 41S for storing the roll RT, and a front opening 41K at the front for taking out or storing the roll RT; and a gate 42 serving as a restriction section, which is displaceable between a first position (closed position) that blocks at least a portion of the front opening 41K, thereby restricting the movement of the roll RT stored in the storage space 41S through the front opening 41K to the outside of the storage section 41, and a second position (open position) that allows the roll RT stored in the storage space to move through the front opening 41K to the outside of the storage section 41. Furthermore, the gate 42 includes a gate front end 52 located at the front opening 41K when displaced to the closed position, and a sliding portion 51 that slides guided by a gate guide portion 43g provided on the frame 43.

[0090] In addition, to accommodate the differences in the width direction dimensions of the roll RT, the cassette 22 requires multiple types with different width direction dimensions. As mentioned above, the frame 43 is composed of two frame members 43Z. Figure 6 as well as Figure 8 Therefore, by setting one of the frame members 43Z to a member having a thickness dimension corresponding to the width dimension of the roll body RT, and setting the other to a member that is common regardless of the difference in the width dimension of the roll body RT, it is possible to achieve commonality of the members and reduce the manufacturing cost of multiple types of cassettes 22. Figure 18A , Figure 18B as well as Figure 18C This is a front view showing examples of several types of tape boxes 22 with different dimensions in the width direction. Figure 19 This is a perspective view of an example of a box 22 with the largest dimension in the width direction.

[0091] Figure 18A It is a structure that removes one of the two frame members 43Z and is made up of a common frame member 43Z, and can cope with the case where the width dimension of the roll RT (i.e. the carrier CT) is smaller than the aforementioned case. Figure 18B The structure is as follows: by increasing the width dimension of one of the two frame members 43Z, it is possible to cope with situations where the width dimension of the roll body RT is larger than the aforementioned cases.

[0092] Figure 18C It is a structure that uses rod-shaped spacers SP to connect two frame members 43Z, and can cope with structures with a greater... Figure 18B For cases with larger width dimensions of the roll RT (also refer to) Figure 19 The two frame members 43Z connected by the spacer SP are common members. It should be noted that... Figure 18B In the case of and Figure 18CIn this case, the gripped parts 45 are respectively provided on both frame members 43Z. This is because: when the tape box 22 is lifted by gripping the gripped parts 45, if the gripped parts 45 are only provided on one of the two frame members 43Z, the tape box 22 will tilt from a vertical position due to the overall center of gravity position, making it difficult to perform the assembly operation on the trolley 21. In addition, it is also because: when gripping one gripped part 45 and forcibly making the tape box 22 vertical, an excessive bending moment may be applied to the gripped part 45, which may damage the gripped part 45.

[0093] Next, the installation steps of the component supply unit 1B provided by the component mounting device 1T with the cassette 22 will be described. In the installation of the component supply unit 1B with the cassette 22, firstly, the receiving part 22A is assembled into the receiving part assembly part 38 of the trolley 21, which serves as the receiving part assembly part.

[0094] When assembling the receiving part 22A into the receiving part assembly part 38, the operator first moves the gate 42 to the open position (second position) using the operating lever 53, and then reverses the top and bottom of the belt box 22. Then, the lower support rod engaging part 43P on the upper part 43a of the frame engages with the lower support rod 35, the upper support rod engaging part 43Q on the lower part 43b of the frame engages with the upper support rod 37, and the engaging groove 43M on the upper part 43a of the frame engages with the receiving part retaining pin 33Q. Figure 11 → Figure 12 With the receiving part 22A assembled onto the trolley 21, the tape box 22 is tilted forward and slightly downward, and the guide surface 43F on the upper part 43a of the frame is in a roughly horizontal position. Figure 12 Additionally, the gate 42 of the receiving section 22A assembled to the trolley 21 is in the open position (second position).

[0095] After the receiving part 22A is assembled to the receiving part assembly part 38 of the trolley 21 as described above, the storage box 22B containing the roll RT is assembled to the storage box assembly part 39 of the trolley 21. The gate 42 of the storage box 22B is in the closed position until the storage box 22B is about to be assembled to the storage box assembly part 39, thus holding the tip of the carrier tape CT pulled from the roll RT by the tape holding part 54 of the gate 42 in the closed position. Figure 12 ).

[0096] Here, the holding of the tip of the carrier CT by the belt holding part 54 is achieved by two belt locking protrusions 55 provided on the belt holding part 54 locking from below with two of the multiple feed holes SH provided on the tip of the carrier CT pulled out from the roll body RT. Figure 6 as well as Figure 12In this state, the head of the CT-carrying head is in a roughly horizontal position.

[0097] Thus, in this embodiment, the tape holding portion 54 located at the front end of the gate 42 (gate front end 52) has two tape locking protrusions 55 that engage with the feed hole SH of the carrier tape CT. These tape locking protrusions 55 hold the carrier tape CT pulled out from the roll RT. At this time, the tip of the carrier tape CT is in a horizontal position. That is, when the gate 42 is in the closed position (first position), the tape holding portion 54 holds the carrier tape CT horizontally.

[0098] When assembling the storage box 22B into the storage box assembly part 39, the operator holds the holding part 45 (if there are two holding parts 45) located on the upper frame part 43a of the frame 43, and then lifts the storage box 22B. Then, the operator pinches the tip of the carrier tape CT held by the tape holding part 54 with their fingers and inserts the tip into the tape inlet 23G at the rear end of the tape feeder 23.

[0099] When the belt feeder 23, which has inserted a carrier CT, detects that the tip of the carrier CT has been inserted into the belt inlet 23G, it begins to pull in the carrier CT. After the belt feeder 23 begins to pull in the carrier CT, the operator moves the operating lever 53 upward, causing the gate 42 to move from the closed position to the open position, thereby opening the front opening 41K of the storage box 22B.

[0100] Figure 20A as well as Figure 20B This is a side sectional view of a portion of the component mounting device 1T showing the installation steps of the tape holder 22. After the operator inserts the tip of the carrier tape CT, which has been pulled out from the roll RT, into the tape inlet 23G of the tape feeder 23, the operator operates the operating lever 53 to open the gate 42. This opens the front opening 41K of the storage box 22B, causing the storage box 22B to move upwards towards the storage box assembly 39. Figure 20A Then, the storage box 22B is lowered, and three storage box retaining pins 33P, which constitute the storage box retaining pin row 33L as the storage box assembly part 39, are inserted into the three pin insertion parts 43S provided on the lower part 43b of the frame of the storage box 22B, thereby assembling the storage box 22B in the storage box assembly part 39 (i.e., the trolley 21). Figure 20B ).

[0101] When the operator assembles the storage box 22B into the storage box assembly part 39, the front end 43E of the lower part (lower frame part 43b) of the storage box 22B passes between a pair of protrusions 44H of the receiving part 22A assembled into the receiving part assembly part 38. Figure 20A → Figure 20B ).like Figure 8 As shown, a conical surface 43D is formed at the lower end of the lower part 43b of the frame, which is shaped (narrowed downward) so that the lower part 43b of the frame can be easily guided between a pair of protrusions 44H.

[0102] When the storage box 22B is assembled to the storage box assembly part 39 as described above (the lower front end 43E passes between the pair of protrusions 44H of the receiving part 22A), the pair of side plates 44 of the storage box 22B are located inside the pair of side plates 44 of the receiving part 22A. Figure 20B Therefore, the storage box 22B is clamped by a pair of side plates 44 of the receiving part 22A located in front of it, and movement in the X direction (the tilting direction to the side) is suppressed, thus stabilizing the posture on the trolley 21.

[0103] Furthermore, at least a portion of the front opening 41K of the storage box 22B is inserted into the front opening 41K of the receiving portion 22A. In other words, the storage box assembly portion 39 assembles the storage box 22B with at least a portion of the front opening 41K of the storage box 22B inserted into the front opening 41K of the receiving portion 22A. As a result, the side plate 44 of the storage box 22B is located further inward than the side plate 44 of the receiving portion 22A, thus preventing malfunctions such as the roll RT card moving from the storage box 22B to the receiving portion 22A getting caught on the edge of the side plate 44.

[0104] Thus, in this embodiment, the storage section 41 with the box 22 (storage box 22B) has a structure that includes an engaging portion, namely a pin insertion portion 43S, capable of engaging with the box holding pin array 33L (three storage box holding pins 33P) of the positioning section of the trolley 21 (i.e., the component mounting device 1T). Furthermore, the storage box 22B is positioned and held by the storage box assembly section 39, which is composed of the box holding pin array 33L (three storage box holding pins 33P). Moreover, while the storage box 22B is held in the storage box assembly section 39, it is clamped by a pair of side plates 44 of the receiving section 22A located in front of it, thereby suppressing movement in the X direction (the lateral tilting direction).

[0105] Figure 21A as well as Figure 21B This is a side sectional view of a part of the component mounting device 1T showing the movement of the roll RT. Figure 22A as well as Figure 22BThis is a side sectional view of a portion of the component mounting device 1T showing the removal procedure of the tape cassette 22. During the assembly of the storage cassette 22B into the storage cassette assembly section 39, the tape feeder 23 pulls in the carrier tape CT. If the pulled-in carrier tape CT is the current tape, it directly transports the carrier tape CT to supply component BH. If the pulled-in carrier tape CT is a supplementary tape, the supplementary tape is kept on standby until the rear end of the current tape is detected to have passed a predetermined position within the tape feeder 23. When the tape feeder 23 begins transporting the supplementary tape, the roll RT stored in the storage cassette 22B is pulled forward and rotated by the carrier tape CT transported by the tape feeder 23, moving into the storage section 41 of the receiving section 22A located in front of it. Figure 21A → Figure 21B → Figure 22A ).

[0106] As described above, when the roll RT moves from the storage box 22B into the receiving section 22A, the roll RT is guided by the guide surface 43F of the receiving section 22A. Furthermore, a pair of side plates 44 of the storage box 22B are located inside the pair of side plates 44 of the receiving section 22A, which are located in front of it. Therefore, the roll RT moves smoothly into the receiving section 22A and is stored therein. Figure 21B → Figure 22A ).

[0107] Figure 23A as well as Figure 23B This is a side sectional view of a portion of the component mounting device 1T showing the installation steps of the storage box 22. After the roll RT stored in the storage box 22B moves into the receiving part 22A, the storage box 22B becomes empty. The empty storage box 22B is removed from the trolley 21 (box assembly part 33). Figure 22B This allows the next reel of tape RT (storage box 22B) to be assembled onto the trolley 21. Furthermore, after the tape feeder 23 advances the supply of component BH, the operator, following the aforementioned procedure, assembles the new tape box 22 onto the box assembly section 33. Figure 23A → Figure 23B ).

[0108] Figure 24A as well as Figure 24B This is a side sectional view of a part of the component mounting device 1T showing the movement of the roll RT. After the rear end of the carrier CT of the roll RT in the receiving section 22A passes a predetermined position within the belt feeder 23, the belt feeder 23 transports the previously idle supplementary belt (the carrier CT in the storage box 22B) as the new current belt. Figure 24A), and continue the supply of component BH. When the conveyor 23 begins to transport the carrier CT from the roll RT stored in the storage box 22B, the roll RT of the carrier CT is pulled forward and rotated, and enters the storage section 41 assembled in the receiving section 22A in front of it ( Figure 24A → Figure 24B Thus, storage box 22B becomes empty and becomes the same as the aforementioned. Figure 22A The same state, the following, will be repeated. Figure 22A → Figure 22B → Figure 23A → Figure 23B → Figure 24A → Figure 24B → Figure 22A The process is as follows. Therefore, the component mounting device 1T can continue to supply component BH by the belt feeder 23 while receiving the replenishment of the roll RT (i.e., the carrier CT).

[0109] Furthermore, there are cases where, when component mounting by the component mounting device 1T is completed, unused carrier tape CT and its roll RT remain in the receiving section 22A. The remaining roll RT is stored or used by the component mounting device 1T for producing other mounting substrates. In this case, the receiving section 22A is a tape cassette 22 that can be used as a storage box 22B, so the receiving section 22A containing the remaining roll RT can be removed from the receiving section assembly section 38 and stored as is. Alternatively, when used by the component mounting device 1T, the removed receiving section 22A can be used as a storage box 22B. In this case, the receiving section 22A is used with the tape cassette 22 reversed, so the winding direction of the roll RT stored in the receiving section 22A is the same as the winding direction when used as a storage box 22B. Therefore, the operation of removing the roll RT and reversing its orientation to store it again when using the receiving section 22A as a storage box 22B can be eliminated.

[0110] As explained so far, the cassette 22 (storage device) of this embodiment supplies the roll RT of the carrier tape CT containing component BH to the component mounting device 1T, and has a structure including a storage section 41 and a gate 42. The storage section 41 has a storage space 41S for storing the roll RT, and has a front opening 41K at the front for taking out or storing the roll RT. The gate 42 is movable between a closed position (first position) that blocks at least a portion of the front opening 41K, thereby restricting the movement of the roll RT to the outside of the storage section 41 through the front opening 41K, and an open position (second position) that allows the roll RT to move to the outside of the storage section 41 through the front opening 41K. Furthermore, the cassette 22, as the storage device (storage box 22B), is mounted on the trolley 21 with the front opening 41K of the storage section 41 facing the component mounting device 1T, and supplies its roll RT to the component mounting device 1T with the gate 42 in the open position.

[0111] In the tape cassette 22 of this embodiment, the roll RT stored in the storage space 41S will not jump out of the storage space 41S when the gate 42 is in the closed position (first position). On the other hand, by placing the gate 42 in the open position (second position), the stored roll RT can be taken out of the storage space 41S. Therefore, according to the tape cassette 22 of this embodiment, the stored roll RT can be reliably supplied to the component mounting device 1T while preventing the stored roll RT from accidentally jumping out.

[0112] Furthermore, the component loading device 1T of this embodiment has the following structure: it includes a storage box assembly section 39 (storage device assembly section) for assembling a storage box 22B (storage device) that stores a roll RT containing a carrier tape CT (replenishment tape); and a receiving section assembly section 38 (receiving section assembly section) for assembling a receiving section 22A (receiving section), which receives the roll RT supplied from the storage box 22B assembled to the storage box assembly section 39 through its front opening 41K. That is, in the component loading device 1T of this embodiment, instead of mounting the storage device (storage box 22B) that stores the roll RT containing the replenishment tape to the storage device (receiving section 22A) that holds the roll RT of the current tape, the storage device is directly mounted to the trolley 21. Therefore, according to the component loading device 1T of this embodiment, not only small roll RTs, but also large roll RTs can be stably held and used for component loading operations. That is, the component mounting device 1T according to this embodiment can also easily handle the large size of the roll.

[0113] As explained above, the component mounting device 1T according to this embodiment can easily handle the large size of the roll.

[0114] So far, embodiments of the present invention have been described, but the present invention is not limited to the above content and various modifications can be made. For example, in the above embodiment, the gate 42 with the box 22 has a J shape as a whole, but as long as it can be displaced between the closed position (first position) where the front opening 41K of the storage part 41 is closed and the open position (second position) where the front opening 41K is open, it is not a problem even if it is not J-shaped.

[0115] Industrial applicability

[0116] It can provide component mounting devices that can handle the large size of the roll.
