Description

Technical Field Technical Field

[0001] This specification discloses the fixing structure and method of the linear motor stator, as well as the component mounting machine. Background Technology

[0002] Previously, a component mounting device was proposed, comprising: an X-beam, two rails for guiding the head to slide freely along the X-axis direction and bolted to the X-beam in a manner arranged along the Z-axis direction; a movable side drive unit mounted on the X-beam side of the head; and a fixed side drive unit mounted on the head side of the X-beam (for example, see Patent Document 1). The fixed side drive unit has an electromagnet and a metal plate-like component connecting the electromagnet and the X-beam. The X-beam has a main body made of carbon fiber reinforced resin, a metal connecting part connecting the rails to the main body, and a metal connecting part connecting the fixed side drive unit to the main body. Each connecting part extends in the X-axis direction and is disposed at one end of the X-beam on the head side in the Y-axis direction, and is fixed to the main body by an adhesive. In addition, mounting holes are formed in each connecting part. To improve mounting accuracy, the mounting surface of the fixed side drive unit of each connecting part is pre-machined. The fixed side drive unit is mounted to the connecting part by inserting a fastener (hex socket head cap screw) into the threaded hole provided in the connecting part by inserting a threaded sleeve or the like.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-138527 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] When using fiber-reinforced resins such as carbon fiber reinforced resin in frames such as X-beams that house linear motor stators, fiber-reinforced resins are typically difficult to process. Therefore, it is necessary to use simple methods to ensure the installation accuracy of the linear motor stator relative to the frame.

[0008] The main objective of this disclosure is to fix a linear motor stator to a fiber-reinforced resin frame with good precision using a simple structure.

[0009] Methods for solving problems

[0010] The following means are employed in this disclosure to achieve the aforementioned principal objectives.

[0011] The linear motor stator fixing structure of the present invention is a linear motor stator fixing structure that fixes the linear motor stator to a frame made of fiber-reinforced resin. Its main features are: a through hole formed in the mounting surface of the linear motor stator in the frame; a connecting member inserted through and bonded to the through hole; and the linear motor stator being bolted to the connecting member.

[0012] According to the linear motor stator fixing structure of the present invention, the linear motor stator is fixed to the frame via a connecting member. By ensuring the precision of the connecting member, the linear motor stator can be fixed to the fiber-reinforced resin frame with good precision using a simple structure.

[0013] This disclosure can also replace the fixing structure of the linear motor stator as a method for fixing the linear motor stator. Therefore, the fixing method of this disclosure can achieve the same effect as the fixing structure of this disclosure.

[0014] Furthermore, the main feature of the component mounting machine disclosed herein is that it comprises: a sliding member having a frame made of fiber-reinforced resin, a connecting member, and a linear motor stator, and being capable of sliding in a predetermined direction, the frame having a through hole, the connecting member being inserted through and bonded to the through hole of the frame, and the linear motor stator being bolted to the connecting member; and a movable member movably supported on the frame and having a linear motor mover facing the linear motor stator.

[0015] In the component mounting machine disclosed herein, the linear motor stator is fixed to the frame via a coupling component. By ensuring the precision of the coupling component, the linear motor stator can be fixed to the fiber-reinforced resin frame with good precision using a simple structure. Therefore, a linear motor comprising a linear motor stator and a linear motor mover can be driven with high precision, further improving mounting accuracy. Attached Figure Description

[0030] Next, the manner in which this disclosure is carried out will be described with reference to the accompanying drawings.

[0031] Figure 1 This is a perspective view of the component mounting machine 10 of this embodiment. Figure 2 This is a top view of the component mounting machine 10 of this embodiment. Figure 3 This is a perspective view of the head 15 and the sliding component 20. Figure 4 This is a 3D view of the Y-axis moving device 50. Figure 5 This is a perspective view of the sliding component 20 and the block component 40. Figure 6 This is the front view of the sliding component 20. Figure 7 yes Figure 6 AA section view. In Figure 1 and Figure 2 In the diagram, the left and right directions are the X-axis, the front and back directions are the Y-axis, and the up and down directions are the Z-axis.

[0032] In this embodiment, the component mounting machine 10 picks up components supplied from the feeder F and mounts them onto the substrate S. For example... Figure 1 , Figure 2As shown, the component mounting machine 10 includes a base 12, a substrate transport device (not shown), first and second feeder sections F1 and F2, first and second heads 15a and 15b, first and second sliding 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 within a housing 11. Strip-shaped support platforms 13 extending longitudinally are provided on the left and right sides of the upper layer of the base 12. The first head 15a and second head 15b are sometimes simply referred to as head 15. The first sliding member 20a and second sliding member 20b are sometimes simply referred to as sliding member 20. The first X-axis moving device 30a and second X-axis moving device 30b are sometimes simply referred to as X-axis moving device 30. The first Y-axis moving device 50a and second Y-axis moving device 50b are sometimes simply referred to as Y-axis moving device 50.

[0033] The feeders for supplying components are detachable from the first and second feeder sections F1 and F2. In this embodiment, the first and second feeder sections F1 and F2 are located on the front and rear sides of the base 12. The first feeder section F1 supplies components to the first head 15a, and the second feeder section F2 supplies components to the second head 15b. Alternatively, the feeder sections may be located only on one side, front or rear.

[0034] The substrate handling device is a belt conveyor that uses a motor to drive the conveyor belt to move the substrate S from left to right.

[0035] The first and second heads 15a and 15b (head 15) have suction nozzles with adsorption elements. For example... Figure 1 and Figure 2 As shown, the first head 15a is supported on the first sliding member 20a in a manner that allows it to move left and right (X-axis). The second head 15b is supported on the second sliding member 20b in a manner that allows it to move left and right (X-axis).

[0036] The first and second sliding components 20a and 20b (sliding components 20) are long strip components extending left and right (X-axis), mounted on a pair of parallel and shared iron Y-axis linear guides 51 (guide rails), and move back and forth (Y-axis) along the pair of Y-axis linear guides 51. Figure 3 As shown, the first and second sliding components 20a and 20b have a frame 21 formed from carbon fiber reinforced resin (CFRP) in a square cylindrical shape. Alternatively, the frame 21 can also be formed from aramid fiber reinforced resin (AFRP). By forming the frame 21 from CFRP or AFRP, the sliding component 20 can be made lightweight, enabling high-speed movement. Furthermore, by forming the frame 21 into a simple square cylindrical shape, the processing of CFRP or AFRP becomes easier, reducing manufacturing costs.

[0037] On the opposing sides (sidewalls) of each frame 21 of the first and second sliding components 20a and 20b, a pair of iron X-axis linear guides 31 (guide rails) extending parallel to each other are respectively joined. The first and second heads 15a and 15b are supported on the first and second sliding components 20a and 20b in a manner that allows them to move left and right along the X-axis linear guides 31.

[0038] Although the engagement of the X-axis linear guide 31 with the frame 21 is not shown, it is accomplished by configuring (fixing) a strip-shaped seat plate and a back plate of approximately the same length as the X-axis linear guide 31 respectively, such that they clamp the side walls of the frame 21 from the inside and outside, and bolting the X-axis linear guide 31 to the surface of the seat plate.

[0039] 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). Figure 3 As shown, the first and second X-axis moving devices 30a and 30b (X-axis moving device 30) have a pair of upper and lower X-axis linear guides 31, an X-axis linear motor 32, a plurality of (four) X-axis guide nuts 36, and an X-axis linear encoder (not shown).

[0040] In this embodiment, the X-axis linear motor 32 is configured as a flat linear motor, having: an X-axis stator 33, which is attached to the side (side wall) of the sliding member 20; and an X-axis mover 34, which is arranged opposite to the X-axis stator 33 at a predetermined distance from front to back.

[0041] like Figure 5 As shown, the X-axis stator 33 is positioned between a pair of upper and lower X-axis linear guides 31 on the side of the frame 21. Figure 6 As shown, the X-axis stator 33 includes: a plate-shaped yoke 331 extending along the X-axis direction; and a plurality of permanent magnets 332 arranged and fixed relative to the yoke 331 along the X-axis direction with alternating N and S pole polarities. In this embodiment, the yoke 331 is divided into multiple sheets (e.g., three sheets), which are respectively mounted on the frame 21 in a manner arranged along the X-axis direction. In this embodiment, as... Figure 7 As shown, the X-axis stator 33 (yoke plate 331) is fixed to the frame 21 by bolts to the connecting part 334 (e.g., boss part) that is bonded to the frame 21. Further details regarding the installation process of mounting the X-axis stator 33 to the frame 21 will be described later.

[0042] The X-axis mover 34 has multiple iron cores formed by stacked electromagnetic steel plates and phase coils wound around the corresponding iron cores. The X-axis mover 34 is supported by X-axis guide nuts 36 mounted on a pair of 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 pairs of X-axis linear guides 31, and the X-axis mover 34 is supported by a total of four X-axis guide nuts 36. The head 15 is supported by the X-axis mover 34 and moves left and right (X-axis) together with the X-axis mover 34 as the head 15 moves along the X-axis.

[0043] In addition, such as Figure 4 , Figure 5 As shown, aluminum or aluminum alloy block components 40 are respectively joined at both ends of the opening of the frame 21. The sliding component 20 moves each block component 40 on the corresponding Y-axis linear guide 51 at both ends via Y-axis moving devices 50 (first Y-axis moving device 50a, second Y-axis moving device 50b), thereby moving back and forth (Y-axis).

[0044] The first Y-axis moving device 50a moves the first sliding member 20a back and forth (along the Y-axis). The second Y-axis moving device 50b moves the second sliding member 20b back and forth (along the Y-axis). Figure 2 , Figure 4 As shown, the first and second Y-axis moving devices 50a and 50b (Y-axis moving device 50) include: a pair of left and right Y-axis linear guides 51; Y-axis linear motors 52, respectively disposed on the left and right sides; and Y-axis guide nuts 56, multiple of which are slidably mounted on each of the left and right pair of Y-axis linear guides 51, and a support block component 40. Figure 2 As shown, a pair of Y-axis linear guides 51 are arranged on the upper surface of the left and right support platforms 13 in a manner that extends along the front and back.

[0045] The Y-axis linear motor 52 is configured as a flat linear motor, comprising: a Y-axis stator 53 fixed to a support platform 13 extending back-to-back; and a Y-axis mover 54 fixed to a block component 40 at predetermined vertical intervals from the Y-axis stator 53. The Y-axis stator 53 has a plurality of permanent magnets arranged in a planar configuration along 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 used in the X-axis stator 33. This component standardization reduces costs. The Y-axis mover 54 has a plurality of iron cores formed by stacking electromagnetic steel plates and phase coils wound around the corresponding iron cores. The Y-axis mover 54 moves back-to-back (Y-axis) by applying a three-phase alternating current to each phase coil.

[0046] Three Y-axis guide nuts 56 are mounted on each of the left and right pairs of Y-axis linear guides 51. Block components 40, fixed to both ends of the sliding component 20, are respectively fixed to the upper surfaces of the three Y-axis guide nuts 56. As a result, the load applied to the block components 40 by the attraction force of the Y-axis linear motor 52 can be distributed approximately evenly among the three Y-axis guide nuts 56, reducing the gap variation between the Y-axis stator 53 and the Y-axis mover 54 caused by the attraction force, thus stabilizing the movement of the sliding component 20, and improving the durability of the Y-axis linear guides 51 and Y-axis guide nuts 56.

[0047] In this way, the head 15 can move in all directions (XY axis direction) by using the Y-axis moving device 50 to move the sliding member 20 back and forth (Y-axis) and by using the X-axis moving device 30 to move the X-axis mover 34 relative to the sliding member 20 left and right (X-axis). As described above, the frame 21 of the sliding member 20 is made of CFRP or AFRP, so by combining it with the block member 40 made of aluminum or aluminum alloy, the sliding member 20 can be made lightweight, and the head 15 can move at a higher speed. Moreover, by making the frame 21 into a square tube shape, the manufacturing cost can be reduced through the simple shape.

[0048] Next, the process of mounting the X-axis stator 33 of the X-axis linear motor 32 onto the frame 21 will be described. Figure 8 This is a process diagram illustrating an example of the stator mounting process for a linear motor. See below for reference. Figures 9-14 The linear motor stator installation process is described. Furthermore, the X-axis linear guide 31 is installed in parallel with the linear motor stator installation process, but since this is not the focus of this disclosure, the description of the X-axis linear guide 31 installation process is omitted.

[0049] In the linear motor stator mounting process, firstly, multiple through holes 211o and 212o for mounting the X-axis stator 33 (yoke plate 331) are formed on the frame 21 (step S100). In this embodiment, as... Figure 9As shown, multiple through holes 211o and 212o are formed to pass through the mounting surface 211 and the opposite surface 212 of the square cylindrical frame 21, which are used to mount the X-axis stator 33, in a straight line. Furthermore, the through holes 211o and 212o can be formed, for example, during the fabrication of the frame 21. Next, adhesive is applied to the outer peripheral surface of the connecting member 334 used to connect the frame 21 and the X-axis stator 33 (step S110). The connecting member 334 is, for example, a boss member, having a head 334h and a shaft portion 334s. In this embodiment, a left-hand thread is formed on the outer peripheral surface of the shaft portion 334s. Then, the connecting member 334 is inserted from the inner surface side of the frame 21 into the through hole 211o formed in the mounting surface 211 of the frame 21 (step S110). In this embodiment, after the plurality of connecting members 334 are roughly positioned relative to the plurality of through holes 211o formed on the mounting surface 211 of the frame 21, the connecting members 334 are inserted using a tool T. Specifically, this is performed as follows. Figure 10 and Figure 11 This is an explanatory diagram illustrating the insertion of the connecting components. First, connecting components 334 are respectively installed on each of the retaining portions of a pair of upper and lower support clamps L, each having multiple retaining portions formed at the same spacing as the multiple through holes 211o, so that the multiple connecting components 334 are held in a row on the support clamps L. Next, the support clamps L are inserted into the interior of the frame 21 from the cylindrical end face of the frame 21, with the multiple through holes 221o of the mounting surface 211 facing each other and the multiple connecting components 334. Then, the front end of the tool T is inserted from the outer surface side through the through hole 212o of the opposite surface 212 and abuts against the head 334h of the connecting component 334, and the tool T is used to press the shaft portion 334s of the connecting component 334 from the inner surface side into the corresponding through hole 211o of the mounting surface 211. As a result, the shaft portion 334s of the connecting component 334 is bonded and fixed to the through hole 211o of the mounting surface 211. By using support clamps L and tools T during the insertion of the connecting member 334, workability can be further improved. The connecting member 334 is fixed to the mounting surface 211 with the front end of the shaft portion 334s protruding outward relative to the mounting surface 211.

[0050] After the multiple connecting parts 334 are glued and fixed to the frame 21, as Figure 12 As shown, tapping is performed to form an internal thread at the center of the shaft portion 334s of the mating member 334 (step S130). In this embodiment, a right-hand thread is formed at the center of the shaft portion 334s in such a way that it engages with a right-hand threaded bolt 333. Next, as... Figure 13As shown, a planar machining (cutting process) is performed to flatten the front end face of the shaft portion 334s of the connecting member 334 for mounting the X-axis stator 33 (yoke plate 331) (step S140). The planar machining is performed such that the front end face of the shaft portion 334s protrudes slightly outward from the mounting surface 211 of the frame 21. Furthermore, the planar machining is performed after the connecting member 334 is bonded to the frame 21 and the mounting plate is installed, with the mounting surface for mounting the X-axis stator 33 (the front end face of the shaft portion 334s of the connecting member 334 bonded and fixed to the frame 21) and the mounting surface for mounting the X-axis linear guide 31 (the surface of the strip-shaped seat plate mounted on the frame 21) approximately parallel. Then, as... Figure 14 As shown, the X-axis stator 33 (yoke plate 331) is brought into contact with the front end face of the shaft portion 334s of the connecting member 334, and the X-axis stator 33 is bolted to the connecting member 334 (step S150), thereby completing the installation of the X-axis stator 33. Bolt tightening is performed by inserting the bolt 333 through the through hole 331o formed in the yoke plate 331 and engaging it with the internal thread formed at the axial center of the shaft portion 334s of the connecting member 334. In this embodiment, the bolt 333 has a right-hand thread, and a left-hand thread is formed on the outer peripheral surface of the shaft portion 334s of the connecting member 334. Therefore, the direction of the rotational force acting on the connecting member 334 when the bolt 333 is threaded to the connecting member 334 becomes the direction of tightening the external thread of the shaft portion 334s of the connecting member 334, thus preventing loosening of the external thread. In addition, bolt 333 can also be formed with a left-hand thread, and a right-hand thread external thread is formed on the outer peripheral surface of the shaft portion 334s of the mating part 334.

[0051] Here, the correspondence between the constituent elements of the embodiment and the constituent elements of the present disclosure as described in the claims is clearly defined. In the embodiment, the X-axis stator 33 of the X-axis linear motor 32 corresponds to the linear motor stator of the present disclosure, the frame 21 corresponds to the frame, the through hole 211o corresponds to the through hole, and the connecting member 334 corresponds to the connecting member. Furthermore, the sliding member 20 corresponds to the sliding member, and the X-axis mover 34 corresponds to the movable member.

[0052] Furthermore, this disclosure is not limited to any of the above-described embodiments. As long as it falls within the technical scope of this disclosure, it can of course be implemented in various ways.

[0053] For example, in the above embodiment, the component mounting machine 10 has two heads 15 (first and second heads 15a and 15b), but it may also have a single head. In this case, the component mounting machine 10 only needs to have one or a set of feeder parts, sliding parts 20, X-axis moving devices 30 and Y-axis moving devices 50 respectively.

[0054] As explained above, in the linear motor stator fixing structure of this disclosure, the linear motor stator is fixed to the frame via a connecting component. By ensuring the precision of the connecting component, the linear motor stator can be fixed to the fiber-reinforced resin frame with good precision using a simple structure.

[0055] In the linear motor stator fixing structure of this disclosure, a threaded groove may be formed on the outer peripheral surface of the connecting member, and the direction of rotation of the threaded groove of the connecting member is different from the direction of rotation of the threaded groove of the bolt used for bolt fastening. In this way, when the linear motor stator bolt is fastened to the connecting member, the rotational force acting on the connecting member can be in the direction of thread fastening of the connecting member, thus preventing the thread from loosening.

[0056] This disclosure can also replace the fixing structure of the linear motor stator with a method for fixing the linear motor stator.

[0057] In the method for fixing the linear motor stator of the present invention, the connecting member can also be inserted through the inner surface of the frame and bonded to the through hole. This allows for more reliable fixing of the connecting member to the fiber-reinforced resin frame. Alternatively, the frame may have a mounting surface for the linear motor stator and a surface opposite to the mounting surface, with through holes formed on both the mounting surface and the surface opposite to the mounting surface. A tool is inserted through the through hole on the opposite surface, and the connecting member is inserted through the through hole on the mounting surface from the inner surface of the frame into the through hole. This improves the workability of fixing the connecting member to the frame. Furthermore, in these cases, after inserting and bonding the connecting member to the through hole, the mounting surface of the linear motor stator on the connecting member can be flattened, so that the linear motor stator abuts against the flattened surface of the connecting member and is bolted to the connecting member. This allows for the linear motor stator to be fixed to the fiber-reinforced resin frame with good precision through simple processing.

[0058] Furthermore, this disclosure can also be configured as a component mounting machine having such a linear motor stator. In the component mounting machine of this disclosure, the linear motor stator is fixed to the frame via a connecting member. By ensuring the precision of the connecting member, the linear motor stator can be fixed to the fiber-reinforced resin frame with good precision using a simple structure. Therefore, a linear motor including a linear motor stator and a linear motor mover can be driven with high precision, and the mounting accuracy can be further improved.

[0059] In the case where the linear motor stator is directly bonded and fixed to the frame, the entire frame needs to be replaced if the linear motor stator is damaged. In contrast, in this disclosure, the linear motor stator is bolted to a joint that is bonded and fixed to the frame, allowing for easy disassembly and replacement relative to the frame. As a result, the recovery cost in case of linear motor failure is reduced, and the recovery time is shortened.
