Summary of the Invention

Problems to be Solved by the Invention

[0004] In the slide member described above, it is required to attach peripheral members such as a rail to the main body of the fiber reinforced resin with sufficient positioning accuracy.

[0005] The main object of the present disclosure is to sufficiently ensure the positioning accuracy of a peripheral member attached to a main body made of a fiber reinforced resin in a slide member that supports a head and is slidable in a predetermined direction.

Means for Solving the Problems

[0006] The present disclosure has taken the following means to achieve the above main object.

[0007] The first slide member of this disclosure is A sliding member that supports the head and is capable of sliding in a predetermined direction, A hollow body formed from fiber-reinforced resin, A pair of plate members are arranged to sandwich the wall surface of the main body from both the inside and outside, and a rail member that guides the head to move is attached to the outside, The gist of it is that it is equipped with the following features.

[0008] In the first slide member of this disclosure, a pair of plate members are arranged so as to sandwich the wall surface of the main body from both the inside and outside. By attaching the rail member to the outer plate member, the positioning accuracy of the rail member can be ensured. Here, "fiber-reinforced resin" includes carbon fiber reinforced resin and aramid resin reinforced fiber (the same applies hereinafter).

[0009] The second slide member of this disclosure is A sliding member that supports the head and is capable of sliding in a predetermined direction, A body formed in a cylindrical shape from carbon fiber reinforced resin so as to extend in a direction perpendicular to the predetermined direction, A plate member formed of metal, positioned on the wall surface of the main body, and to which a first rail member is attached that guides the head so as to be movable in the orthogonal direction, A pair of block members formed of aluminum or an aluminum alloy, attached to both ends of the opening of the main body and movable along a pair of second rails extending in the predetermined direction, The gist of it is that it is equipped with the following features.

[0010] In the second slide member of this disclosure, the first rail member is attached to the main body via a metal plate member, thereby ensuring the positioning accuracy of the first rail member. Furthermore, by attaching aluminum or a pair of aluminum block members to both ends of the opening of the main body made of carbon fiber reinforced resin, the slide member can be made lighter while maintaining rigidity. As a result, the slide member can be moved at high speed.

[0011] The third slide member of this disclosure is A sliding member that supports the head and is capable of sliding in a predetermined direction, A body formed in a cylindrical shape from fiber-reinforced resin so as to extend in a direction perpendicular to the predetermined direction, and having a notch at the open end, A block member having a fitting portion that fits into the open end of the main body, and a protrusion that fits into the notched portion when the fitting portion is fitted into the open end, The gist of it is that it is equipped with the following features.

[0012] In the third slide member of this disclosure, when the fitting portion of the block member is fitted into the open end of the main body, the protrusion of the block member fits into the notch of the main body, thereby ensuring positional accuracy of the block member relative to the main body.

[0013] The fourth slide member of this disclosure is A sliding member that supports the head and is capable of sliding in a predetermined direction, A hollow body formed from fiber-reinforced resin and having through holes that penetrate in the thickness direction, A peripheral member formed of metal, having a female threaded portion that communicates with the through hole when positioned against the inner surface of the wall of the main body, and fixed to the main body when a bolt is inserted into the through hole and the male threaded portion of the bolt is attached to the female threaded portion, The gist of it is that it is equipped with the following features.

[0014] In the fourth slide member of the present disclosure, by forming the main body with a fiber-reinforced resin, weight reduction can be achieved while ensuring rigidity. As a result, the movement of the head can be made faster. Further, a through-hole is provided in the main body made of fiber-reinforced resin, and a female screw portion is provided in the peripheral member made of metal for bolt fastening, so that the positioning accuracy of the peripheral member attached to the main body made of fiber-reinforced resin can be ensured.

[0015] In the manufacturing method of the slide member of the present disclosure, since the rail member is attached to the main body of the fiber-reinforced resin with a plate member interposed therebetween, the positioning accuracy of the rail member can be ensured.

[0016] In the component mounting machine of the present disclosure, since the first slide member of the present disclosure described above is provided, the same effects as those of the first slide member can be achieved.

Figure 12 is a bottom view of the slide member 20 and the block member 40. Figure 13 is a schematic configuration diagram of the X-axis linear encoder 38 and the Y-axis linear encoder 58. In Figures 1 and 2, the left-right direction is the X-axis direction, the front-back direction is the Y-axis direction, and the up-down direction is the Z-axis direction.

[0020] The component mounting machine 10 of this embodiment picks up components supplied from a feeder F and mounts them onto a substrate S. As shown in Figures 1 and 2, the component mounting machine 10 comprises a base 12, a substrate transport device (not shown), first and second heads 15a and 15b, first and second slide members 20a and 20b, first and second X-axis moving devices 30a and 30b, and first and second Y-axis moving devices 50a and 50b. These are housed in a housing 11. On both the left and right sides of the upper part of the base 12, there are strip-shaped support bases 13 that extend in the front-to-back direction. The first head 15a and the second head 15b may be simply referred to as head 15. The first slide member 20a and the second slide member 20b may be simply referred to as slide member 20. The first X-axis moving device 30a and the second X-axis moving device 30b may be simply referred to as X-axis moving device 30. The first Y-axis moving device 50a and the second Y-axis moving device 50b are sometimes simply referred to as the Y-axis moving device 50.

[0021] The substrate transport device is a belt conveyor device that transports substrates S on a conveyor belt from left to right by driving the conveyor belt with a motor.

[0022] The first and second heads 15a and 15b (head 15) have nozzles for picking up parts. As shown in Figures 1 and 2, the first head 15a is supported on a first slide member 20a so as to be movable left and right (X-axis). The second head 15b is supported on a second slide member 20b so as to be movable left and right (X-axis).

[0023] The first and second slide members 20a and 20b (slide members 20) are elongated members extending left and right (X-axis), and are arranged parallel to each other and shared by a pair of left and right iron Y-axis linear guides 51 (guide rails), and move back and forth (Y-axis) along the pair of Y-axis linear guides 51. As shown in Figures 3 to 5, the first and second slide members 20a and 20b have a slide member body 21 formed in the shape of a rectangular tube from carbon fiber reinforced polymer (CFRP). The slide member body 21 may also be formed from aramid fiber reinforced polymer (AFRP). By forming the slide member body 21 from CFRP or AFRP, the slide member 20 can be made lighter and the slide member 20 can be moved at high speed. In addition, by forming the slide member body 21 in a simple rectangular tube shape, processing with CFRP or AFRP is made easier and manufacturing costs can be reduced.

[0024] A pair of upper and lower iron X-axis linear guides 31 (guide rails) are attached to the opposing sides (side walls) of the slide member bodies 21 of the first and second slide members 20a and 20b, respectively, extending parallel to each other from left to right. The first and second heads 15a and 15b are supported by the first and second slide members 20a and 20b so as to be movable from left to right along the X-axis linear guides 31.

[0025] As shown in Figure 5, the X-axis linear guide 31 is joined to the slide member body 21 by positioning (fixing) strip-shaped base plates 22 and back plates 23, each approximately the same length as the X-axis linear guide 31, so as to sandwich the side walls of the slide member body 21 from both the inner and outer surfaces, and then fastening the X-axis linear guide 31 to the surface of the base plate 22 with bolts 26. The base plate 22 and back plate 23 are made of aluminum or an aluminum alloy, respectively.

[0026] The joining of the X-axis linear guide 31 is carried out in more detail as follows. First, multiple through holes 211 and 212 are formed in the slide member body 21 at predetermined intervals in the left-right (X-axis) direction by drilling, and female screw holes 221 and 231 communicating with the corresponding through holes 211 and through holes 222 and 232 communicating with the corresponding through holes 212 are formed in the seat plate 22 and back plate 23 by tapping and drilling, respectively. Next, the back plate 23 is placed on the inner surface of the slide member body 21 so as to sandwich the side wall of the slide member body 21 from both the inner and outer surfaces, and the seat plate 22 is placed on the outer surface of the slide member 20, and the seat plate 22 and back plate 23 are positioned relative to the slide member 20 by inserting the positioning pins 25 through the through holes 212, 222, and 232 (see Figure 6). Next, the base plate 22 and back plate 23 are fixed to the slide member body 21 by inserting and screwing the male threaded portion of the bolt 24 (low-profile bolt) into the female threaded hole 221, through hole 211, and female threaded hole 231 (see Figure 6). Next, the surface (outer surface) of the base plate 22 attached to the slide member body 21 is flattened, and multiple female threaded holes 233, 223 are formed by tapping so that they penetrate from the base plate 22 through the slide member 20 to the back plate 23 (see Figure 7). Then, the X-axis linear guide 31 is fastened to the base plate 22 and back plate 23 with bolts 26 to complete the joining of the X-axis linear guide 31 (see Figure 8). This allows the X-axis linear guide 31 to be attached to the slide member body 21 made of CFRP or AFRP with good positioning accuracy.

[0027] The first X-axis moving device 30a moves the first head 15a left and right (X-axis). The second X-axis moving device 30b moves the second head 15b left and right (X-axis). As shown in Figure 3, the first and second X-axis moving devices 30a, 30b (X-axis moving devices 30) each include a pair of upper and lower X-axis linear guides 31, an X-axis linear motor 32, a plurality (four) X-axis guide nuts 36, and an X-axis linear encoder 38 (see Figure 13).

[0028] In this embodiment, the X-axis linear motor 32 is configured as a flat-type linear motor having an X-axis stator 33 attached to the side surface (side wall) of the slide member 20, and an X-axis movable element 34 positioned opposite the X-axis stator 33 at a predetermined distance in the front and rear directions. The X-axis stator 33 has a plurality of permanent magnets arranged between a pair of upper and lower X-axis linear guides 31 on the side surface of the slide member 20, with alternating N-pole and S-pole polarities along the X-axis linear guides 31. The X-axis movable element 34 has a plurality of cores, each made by laminating electromagnetic steel sheets, and each phase coil wound around the corresponding core. The X-axis movable element 34 is supported by X-axis guide nuts 36 attached to each of the upper and lower X-axis linear guides 31, and moves left and right (X-axis) by applying a three-phase alternating current to each phase coil. In this embodiment, two X-axis guide nuts 36 are arranged on each of the upper and lower X-axis linear guides 31, and the X-axis movable element 34 is supported by a total of four X-axis guide nuts 36. The head 15 is supported by the X-axis movable element 34, and moves left and right (along the X-axis) together with the X-axis movable element 34 as the X-axis movable element 34 moves left and right (along the X-axis).

[0029] As shown in Figure 13, the X-axis linear encoder 38 includes an X-axis linear scale 381 and an X-axis detection head 382. The X-axis linear scale 381 is positioned on the bottom surface (bottom wall) of the sliding member 20 so as to extend left and right (in the X-axis direction). The X-axis detection head 382 is attached directly or indirectly to the head 15 and detects the position of the head 15 in the left-right (X-axis) direction by reading the X-axis linear scale 381.

[0030] Furthermore, as shown in Figures 1 and 9, block members 40 made of aluminum or aluminum alloy are joined to both ends of the opening of the slide member body 21. The slide member 20 moves back and forth (Y-axis) at both ends by Y-axis moving devices 50 (first Y-axis moving device 50a, second Y-axis moving device 50b), which move each block member 40 on the corresponding Y-axis linear guide 51.

[0031] The block member 40 is joined to the slide member body 21 by fitting the fitting portion 41 of the block member 40 to the inner surface of the open end of the slide member body 21 and then bolting the two together, as shown in Figures 10 to 12. A notch 214 is formed on the bottom surface (bottom wall) of the slide member body 21, and a protrusion 411 is formed on the bottom surface of the fitting portion 41 of the block member 40, which protrudes outward and fits into the notch 214 when the fitting portion 41 is fitted to the slide member body 21. As a result, the block member 40 is positioned relative to the slide member body 21 when the fitting portion 41 is fitted to the slide member body 21, thereby ensuring positional accuracy relative to the slide member body 21.

[0032] The joining of the block member 40 to the slide member body 21 is carried out in more detail as follows. First, through holes 213 (two through holes 213 on the front wall and one through hole 213 on the rear wall in this embodiment) are formed at both ends in the left-right (X-axis) direction of both sides (side walls) in the front-rear (Y-axis) direction of the slide member body 21 by drilling (see Figures 6 to 8 and 10). Next, multiple female screw holes 412 that communicate with the corresponding through holes 213 are formed on both sides of the fitting portion 41 of the block member 40 in the front-rear (Y-axis) direction by tapping (see Figures 11 and 12). Then, adhesive is applied to the surface of the fitting portion 41 and the fitting portion 41 is fitted to the inner side of the open end of the slide member body 21. Finally, the male threads of the bolts 27 are inserted through the multiple through holes 213 and screwed into the female screw holes 412, thereby completing the joining of the block member 40. By using the bolt 27, the block member 40 can be positioned relative to the slide member body 21 for bonding, and the position of the block member 40 can be maintained for the curing of the adhesive. In this embodiment, the flattening (surface processing) of the seat plate 22 to which the X-axis linear guide 31 described above is joined is performed after the block member 40 is bonded (joined) to the slide member body 21. In addition, as shown in Figure 14, surface processing is also performed on the contact surface 401 on which the X-axis movable element 34 contacts the block member 40, the mounting surface 402 of the stopper that contacts the block member 40 of other slide members 20 facing each other in the front and rear (Y-axis direction), the mounting surface of the Y-axis guide nut 56 described later, the mounting surface of the Y-axis movable element 54 described later, and the mounting surface of the protrusion 411 to which the Y-axis detection head 582 described later is attached.

[0033] The first Y-axis moving device 50a moves the first slide member 20a back and forth (Y-axis). The second Y-axis moving device 50b moves the second slide member 20b back and forth (Y-axis). As shown in Figures 2 and 9, the first and second Y-axis moving devices 50a, 50b (Y-axis moving devices 50) each include a pair of left and right Y-axis linear guides 51, Y-axis linear motors 52 provided on the left and right sides respectively, multiple Y-axis guide nuts 56 slidably mounted on each of the left and right Y-axis linear guides 51 and supporting the block member 40, and a Y-axis linear encoder 58 (see Figure 13).

[0034] As shown in Figure 2, the pair of left and right Y-axis linear guides 51 are positioned so as to extend front to back on the upper surfaces of the left and right support bases 13.

[0035] As shown in Figure 9, the Y-axis linear motor 52 is configured as a flat-type linear motor having a Y-axis stator 53 fixed to a support base 13 so as to extend in the front-rear direction, and a Y-axis movable element 54 fixed to a block member 40 so as to face the Y-axis stator 53 at a predetermined vertical distance. The Y-axis stator 53 has a plurality of permanent magnets arranged flat on the same plane as the Y-axis linear guide 51, with alternating N and S pole polarities. In this embodiment, the permanent magnets of the Y-axis stator 53 are the same as those of the X-axis stator 33. Costs can be reduced by commonizing parts. The Y-axis movable element 54 has a plurality of cores, each made by laminating electromagnetic steel sheets, and each phase coil wound around the corresponding core. The Y-axis movable element 54 moves back and forth (Y-axis) by applying a three-phase alternating current to each phase coil.

[0036] As shown in Figure 9, three Y-axis guide nuts 56 are attached to each of the left and right pair of Y-axis linear guides 51. The block members 40, which are fixed to both ends of the slide member 20, are each fixed to the upper surface of the three Y-axis guide nuts 56. This allows the load applied to the block members 40 by the suction force of the Y-axis linear motor 52 to be distributed almost uniformly across the three Y-axis guide nuts 56, thereby reducing the gap change between the Y-axis stator 53 and the Y-axis movable member 54 due to this suction force, stabilizing the movement of the slide member 20, and improving the durability of the Y-axis linear guides 51 and Y-axis guide nuts 56.

[0037] As shown in Figure 13, the Y-axis linear encoder 58 includes a Y-axis linear scale 581 and a Y-axis detection head 582. The Y-axis linear scale 581 is positioned to extend in the front-to-back (Y-axis) direction on each of the opposing sides of the left and right support bases 13. The Y-axis detection head 582 is provided on the top surface of the aforementioned protrusion 411 that fits into the notch 214 of the slide member 20, and detects the position of the head 15 (slide member 20) in the front-to-back (Y-axis) direction by reading the Y-axis linear scale 581.

[0038] Thus, the head 15 can move in the forward, backward, left, and right directions (XY axis directions) by moving the slide member 20 back and forth (Y axis) with the Y-axis moving device 50, and by moving the X-axis movable element 34 left and right (X axis) relative to the slide member 20 with the X-axis moving device 30. As described above, since the slide member body 21 of the slide member 20 is made of CFRP or AFRP, the slide member 20 can be made lighter by combining it with a block member 40 made of aluminum or aluminum alloy, making it possible to move the head 15 at a higher speed. Moreover, by making the slide member body 21 a rectangular tube shape, the manufacturing cost can be reduced due to the simple shape.

[0039] Furthermore, the base plate 22 and back plate 23 are positioned so as to sandwich the wall surface of the slide member body 21 from both the inner and outer sides, and the X-axis linear guide 31 is attached to the surface of the base plate 22, allowing the X-axis linear guide 31 to be attached to the slide member body 21 made of CFRP or AFRP with high positioning accuracy.

[0040] Furthermore, a notch 214 is formed at the open end of the slide member body 21, and a protrusion 411 is formed on the fitting portion 41 of the block member 40 that is fitted to the open end. When the block member 40 is fitted to the open end of the slide member body 21, the protrusion 411 fits into the notch 214 and is positioned accordingly. This allows the block member 40 to be attached to the slide member body 21 made of CFRP or AFRP with good positioning accuracy.

[0041] Here, the correspondence between the components of the embodiment and the components of the present disclosure as described in the claims will be clarified. The slide member body 21 of the embodiment corresponds to the body of the present disclosure, and the seat plate 22 and back plate 23 correspond to a pair of plate members. The block member 40 corresponds to a block member. The notch 214 of the slide member body 21 corresponds to a notch, the fitting portion 41 of the block member 40 corresponds to a fitting portion, and the protrusion 411 corresponds to a protrusion. The Y-axis linear scale 581 corresponds to a linear scale, and the Y-axis detection head 582 corresponds to a detection head. The block member 40, seat plate 22, and back plate 23 correspond to peripheral members. The head 15 (first head 15a, second head 15b) corresponds to a head.

[0042] It goes without saying that this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of this disclosure.

[0043] For example, in the embodiment described above, the component mounting machine 10 is provided with two heads 15 (first and second heads 15a and 15b), but it may also be provided with a single head. In this case, the component mounting machine 10 only needs to be provided with one set each of the sliding member 20, the X-axis moving device 30, and the Y-axis moving device 50.

[0044] As described above, in the first slide member of this disclosure, a pair of plate members are arranged so as to sandwich the wall surface of the main body from both the inside and outside. By attaching the rail member to the outer plate member, the positioning accuracy of the rail member can be ensured.

[0045] Furthermore, in the second slide member of this disclosure, the first rail member is attached to the main body via a metal plate member, thereby ensuring the positioning accuracy of the first rail member. In addition, by attaching aluminum or a pair of aluminum block members to both ends of the opening of the main body made of carbon fiber reinforced resin, the slide member can be made lighter while ensuring rigidity. As a result, the slide member can be moved at high speed.

[0046] Furthermore, in the third slide member of this disclosure, when the fitting portion of the block member is fitted into the open end of the main body, the protrusion of the block member fits into the notch of the main body, thereby ensuring positional accuracy of the block member relative to the main body. In this third slide member, a detection head of a linear scale extending in the predetermined direction may be attached to the protrusion. In this way, the positioning portion of the block member and the mounting portion of the detection head can be combined, making the configuration simpler.

[0047] Furthermore, in the fourth slide member of this disclosure, the main body is made of fiber-reinforced resin, which allows for weight reduction while maintaining rigidity. As a result, the movement of the head can be made faster. In addition, since the fiber-reinforced resin main body is provided with a through hole and the metal peripheral member is provided with a female thread for bolt fastening, the positioning accuracy of the peripheral member attached to the fiber-reinforced resin main body can be ensured. In this case, the peripheral member includes a pair of block members having a fitting portion that fits into the inner surface of the open end of the main body, the fitting portion having a female thread that communicates with the through hole when fitted into the open end of the main body, and the block member may be fixed to the main body by inserting a bolt into the through hole and attaching the male thread of the bolt to the female thread of the fitting portion. In this way, the positioning accuracy of the block member can be improved. Furthermore, in these cases, the peripheral member may include a pair of plate members that are positioned to sandwich the wall surface of the main body from both the inside and outside, and to which rail members that guide the head to move in the orthogonal direction are attached, and the pair of plate members may have female threads that communicate with the through hole, and a bolt may be inserted through the through hole and the male threads of the bolt attached to the female threads of the pair of plate members to fix it to the main body. This improves the positioning accuracy of the rail member.

[0048] This disclosure is not limited to a slide member, but may also be a method for manufacturing a slide member. Furthermore, it may be a component mounting machine comprising a head and a slide member. [Industrial applicability]
