Description
TECHNICAL AREA
[0001] The present disclosure relates to a component assembly device and an assembly head. STATE OF THE ART
[0002] A component mounting device that mounts a component onto a substrate comprises a mounting head that moves up and down, rotates about a vertical shaft, and has a nozzle that holds the component. One such mounting head is known that includes a shaft with a nozzle attached to its lower end, a lifting unit that raises and lowers the shaft, a rotating unit that rotates the shaft, and an anti-rotation unit that prevents the lifting unit from rotating with the shaft (for example, patent reference 1). The anti-rotation unit described in patent reference 1 comprises a holding element with a bearing that rotates about a horizontal shaft contained in the lifting unit, and a guide element that is configured in the vertical direction with a guide groove that guides the bearing from the left and right.The anti-rotation unit prevents the retaining element from rotating by pressing the bearing against the guide groove, and allows the retaining element to move up and down as the bearing moves up and down along the guide groove. QUOTE LIST PATENT LITERATURE
[0003] Patent literature 1: JP3928409B SUMMARY OF THE INVENTIONAL PROBLEM

[0009] An embodiment that specifically discloses the configurations and operating modes of a component assembly device and a method for attaching electronic components according to the present disclosure is described in detail below with reference to the drawings, where appropriate. Superfluous detailed descriptions may be omitted. For example, detailed descriptions of known facts and redundant descriptions of essentially the same configurations may be omitted. This is to avoid unnecessary redundancies in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are intended to provide those skilled in the art with a complete understanding of the present disclosure and are not intended to limit the subject matter described in the claims.
[0010] In the following, the conveying direction of a substrate is defined as the X-axis direction, a direction orthogonal to the X-axis direction in a horizontal plane is defined as the Y-axis direction, and a direction perpendicular to an XY plane is defined as the Z-axis direction. The positive side in the Y-direction is also referred to as the "front," and the negative side in the Y-direction is also referred to as the "back." The Z-axis direction is also referred to as the "vertical direction," the positive side in the Z-direction is also referred to as the "top," and the negative side in the Z-direction is also referred to as the "bottom." (Forms of execution)
[0011] Fig. Figure 1 is a top view showing a configuration example of a component assembly device according to an embodiment of the present disclosure. Fig. Figure 2A is a top view showing a configuration example of a mounting head provided in the component assembly device. Fig. 2B is a front view showing the configuration example of the mounting head.
[0012] First, using Fig. Figure 1 describes a configuration of a component assembly device 1. The component assembly device 1 performs a component assembly operation to mount a component, fed by a component feeder, onto a substrate. A substrate conveying mechanism 3 is arranged along an X-axis in the center of a base 2. The substrate conveying mechanism 3 transports a substrate P, fed upstream, into a mounting position and positions and holds the substrate P there. Furthermore, the substrate conveying mechanism 3 transports the substrate P downstream after the placement operation.
[0013] The substrate conveying mechanism 3 is equipped with component feeding units 4 on two corresponding sides (in a front-back direction along a Y-axis). A plurality of belt feeders 5 are installed along the X-axis on each of the component feeding units 4. The belt feeder 5 conveys a component belt, which is equipped with a pocket for storing a component, in one direction (belt feed direction) from outside the component feeding unit 4 to the substrate conveying mechanism 3, thereby feeding the component to a component feed position where it is picked up by an assembly head described later.
[0014] In Fig. 1 The base 2 is provided at each of the two end sections in the X-axis on a top surface with a Y-axis table 6, which includes a linear drive mechanism along the Y-axis. A carrier 7 with a similar linear drive mechanism, which is movable along the Y-axis, is coupled to the Y-axis table 6. The carrier 7 is arranged along the X-axis. A mounting head 8 is attached to the carrier 7 via a plate 7a such that it is movable along the X-axis. The mounting head 8 can be mounted on and detached from the plate 7a.
[0015] As in the Fig. 2A and Fig. As shown in Figure 2B, the assembly head 8 comprises a plurality of component intake units 9. Each of the component intake units 9 is provided with a nozzle 10 at its lower section, which draws in and holds a component. The component intake unit 9 includes a lifting motor 9a, which raises and lowers the nozzle 10 along the Z-axis.
[0016] In Fig. 1. The Y-axis table 6 and the support 7 form a head movement mechanism that moves the assembly head 8 along the X-axis and the Y-axis. The head movement mechanism and the assembly head 8 perform one assembly revolution, during which a component is drawn from the belt feed 5 arranged in the component feed unit 4 by the nozzle 10 attached to the component suction unit 9 and mounted at a mounting position on the substrate P, which is positioned by the substrate conveying mechanism 3. In this way, the nozzle 10 mounts the component picked up from the component feed unit 4 onto the substrate P.
[0017] Next, the configuration of the mounting head 8 will be described with reference to the Fig. 2A and Fig. 2B described. The assembly head 8, which can be attached to and detached from the plate 7a, comprises a plurality of component intake units 9(1) to 9(16). In this example, the assembly head 8 comprises eight component intake units 9 along the X-axis in two rows along the Y-axis. That is, the assembly head 8 comprises eight component intake units 9(1) to 9(8) in the first row and eight component intake units 9(9) to 9(16) in the second row. Accordingly, the assembly head 8 has an inline multi-head structure.
[0018] In Fig. 2B Each of the component intake units 9(1) to 9(16) comprises a shaft 11 (spindle) extending downwards along the Z-axis. The shaft 11 passes through a through-hole 20a (see Fig. 4), which passes vertically through (is inserted into) a block element 20 and projects downwards from the block element 20. The shaft 11 projecting downwards from the block element 20 is provided at its lower end with a nozzle holder 12. The nozzle 10 is attached to the nozzle holder 12.
[0019] The block element 20 moves along a groove 13a (see Fig. 4, Fig. 6A and the like), which extends upwards and downwards and is formed in a plate element 13 (positioning plate) located below the component intake units 9(1) to 9(16). By driving the lifting motor 9a, each of the component intake units 9(1) to 9(16) raises and lowers the nozzle 10 attached to its lower section (arrow a). In this way, the lifting motor 9a, the shaft 11, the block element 20, and the nozzle holder 12 form a lifting unit 14 that raises and lowers the nozzle 10. The assembly head 8 includes a nozzle rotation mechanism (not shown) that rotates the shaft 11 about the Z-axis and rotates the nozzle 10.
[0020] Next, detailed configurations of the plate element 13 and the block element 20 will be given with reference to the Fig. 3A to 6C described.
[0021] Fig. 3A is a top view showing a configuration example of the mounting head, which includes a plate element and a block element. Fig. 3B is a side view showing the configuration example of the mounting head, which includes the plate element and the block element. Fig. Figure 4 is an enlarged top view showing the configuration example of the mounting head, which includes the plate element and the block element. Fig. Figure 5 is a perspective view that shows a configuration example of the block element. Fig. 6A is a perspective view showing a configuration example of the plate element. Fig. Figure 6B is an enlarged top view showing the configuration example of the plate element. Fig. 6C is an enlarged front view showing the configuration example of the plate element.
[0022] Fig. Figure 4 is an enlarged view of the environment of block element 20, which is associated with the in Fig. 3A is connected to a component intake unit 9(16) marked with a circle A. Fig. Figure 5 represents an environment of the block element 20, which is connected to the component intake unit 9(16), as seen from the side of the plate element 13.
[0023] In Fig. 6A are a plurality of upwardly and downwardly extending grooves 13a formed in a side face of the plate element 13 corresponding to the positions of the plurality of component intake units 9(1) to 9(16). In this example, eight grooves 13a are formed in two side faces of the plate element 13 along the Y-axis direction. Each of the grooves 13a comprises a pair of wall faces 13c, 13d extending from a bottom face 13b of the groove 13a to the side face of the plate element 13. The bottom face 13b is a face located near the center of the plate element 13 in the Y-direction and corresponds to the bottom face of the groove 13a when viewed from the Z-direction. Furthermore, two adjacent grooves 13a in the side surface of the plate element 13 are connected via a connecting surface 13e, which connects two wall surfaces 13c, 13d close together between the two wall surfaces of the two adjacent grooves 13a.The connecting surface 13e of two adjacent grooves 13a is, for example, a surface that runs parallel to the bottom surface 13b of the groove 13a and is spaced in the Y direction from the center of the plate element 13.
[0024] For example, the wall surface 13c acts as the first guide 15 and the connecting surface 13e as the second guide 16. That is, the plate element 13 is provided along a lifting direction (Z-axis direction) in which the nozzle 10 is raised and lowered, and includes the first guide 15 and the second guide 16, which correspond to the lifting unit 14.
[0025] In the Fig. 3A to 5, the shaft 11 is arranged in the block element 20 by penetrating (being inserted into) the through-hole 20a formed in the block element 20. A pivot joint 21, which supports the shaft 11 rotating about the Z-axis, is arranged on an upper section of the block element 20. A bearing BR is arranged on a rear side 20b of the block element 20, which faces the plate element 13. The bearing BR acts as the first guide receptacle 22.
[0026] In the Fig. 4 and Fig. 5. The bearing BR (first guide receptacle 22) is attached to the rear side 20b of the block element 20 by means of a first shaft 22a, which extends in one direction (Y-axis direction) orthogonal to a direction (X-axis direction) in which the groove 13a is located. The bearing BR rotates about the first shaft 22a.
[0027] The block element 20 has a block end 20d that projects from the rear side 20b towards the side surface of the plate element 13. A block end 20d is provided on the rear side 20b of each of the two end sections of the block element 20 in the X-axis direction. The block end 20d functions as a second guide receptacle 23.
[0028] The block end 20d has a contact surface 20c on the side of the plate element 13. The block element 20 moves up and down relative to the plate element 13, while the side surface (connecting surface 13e) of the plate element 13 is in contact with the contact surface 20c. The plate element 13 is provided with an outlet (not shown) in part of its side surface, which directs the air pressure generated by an air pressure source (not shown) via an outlet (not shown) to an inlet (not shown) provided in the contact surface 20c of the block element 20. The inlet and outlet can direct the air pressure in a region where the block element 20 moves up and down relative to the plate element 13.
[0029] The block element 20 is provided with a line (not shown) that directs the air pressure introduced from the inlet to an opening 10a located in a tip section of the nozzle 10. That is, the block element 20 serves to introduce the air pressure generated by the air pressure source into the opening 10a, which is located in the tip section of the nozzle 10 on a component suction side. The lifting unit 14 comprises the block element 20, and the first guide receptacle 22 and the second guide receptacle 23 are arranged on the block element 20. The first guide receptacle 22 and the second guide receptacle 23 can also be arranged at a location other than the block element 20. The first guide receptacle 22 is in contact with the first guide 15. The second guide receptacle 23 is in contact with the second guide 16.
[0030] Next, the plate element 13 and the block element 20 are considered taking into account the prestress with reference to the Fig. 7 and Fig. 8 described.
[0031] Fig. Figure 7 represents an example of a first prestressing direction when the plate element is moved in a substrate conveying direction (X-axis direction). Fig. Figure 8 shows an example of the plate element and the block element in a state in which a prestress is applied in the first prestressing direction and a second prestressing direction.
[0032] As in the Fig. 3A and Fig. As shown in Figure 7, the plate element 13 exhibits repeated irregularities along the X-axis in the Y-axis direction. The concave part of the plate element 13 is formed with the groove 13a, in which the bearing BR is located. The plate element 13 also has a convex part formed between adjacent grooves 13a. A region RD in Fig. 3A has a length that is essentially equal to the length of plate element 13 in the Y-axis direction and slightly greater than the length of plate element 13 in the X-axis direction. Therefore, plate element 13 is positioned in the Y-axis direction; that is, its position along the Y-axis is fixed. On the other hand, the position of plate element 13 in the X-axis direction can be adjusted, and plate element 13 can be positioned and fixed in any direction along the X-axis. By adjusting the position of plate element 13 in the X-axis direction, a distance is set between the wall surface 13c of the groove 13a and the bearing BR. For example, the distance can be adjusted so that the wall surface 13c and the bearing BR are separated, so that the wall surface 13c and the bearing BR are in contact, so that the bearing BR is preloaded towards the wall surface 13c, and so on.
[0033] For example, in Fig. As shown in Figure 7, if the bearing BR is positioned in a state where it is prestressed against the wall surface 13c, the position of the plate element 13 along the X-axis direction can be fixed in a state where a prestress is exerted on the wall surface 13c in a first prestressing direction α. That is, in Fig. 7 the plate element 13 is moved positively in the direction of the X-axis and positioned so that the bearing BR is preloaded to the wall surface 13c (i.e. negatively in the direction of the X-axis, in the direction of the first preload direction α) and for example by a pin p1 or a bolt (see Fig. 3A) is fixed in its position in a pressed state. Accordingly, a position of the block element 20, which includes the first guide receptacle 22, is fixed relative to the first guide 15 in a state in which a preload is exerted in the first preload direction α in the X-axis direction, and vibrations in the X-axis direction can be reduced.
[0034] As in Fig. As shown in Figure 8, the block element 20 is pivotable about an axis (axis 11a) of the shaft 11. Therefore, when the plate element 13 is displaced and positioned in the X-axis direction towards the positive side, the bearing BR is preloaded against the wall surface 13c (in the direction of the first preload direction α), with a force acting in the direction from the wall surface 13c to the bearing BR (i.e., in a direction opposite to the first preload direction α) about the axis 11a of the shaft 11, and the block element 20 rotates in a direction of rotation (for example, clockwise). Fig. 8) from the wall surface 13c in the direction of the bearing BR. In this case, the block end 20d of the block element 20 is subjected to a clockwise force, comes into contact with the connecting surface 13e, and is preloaded. Furthermore, a first plane H1 intersects a second plane H2 along (e.g., parallel to) a contact surface where the bearing BR comes into contact with the wall surface 13c, and a second plane H2 intersects a contact surface where the block end 20d comes into contact with the connecting surface 13e. Here, the first plane H1 and the second plane H2 can intersect at a right angle or at an angle other than a right angle. Accordingly, the position of the block element 20, which includes the second guide receptacle 23, is fixed relative to the second guide 16 in a state in which the preload is applied in a second preload direction β in the Y-axis direction, and vibrations in the Y-axis direction can be reduced.
[0035] Therefore, the first guide 15 is pre-tensioned to the first guide receptacle 22, and the second guide 16 is pre-tensioned to the second guide receptacle 23, thereby regulating the positions of the block element 20 in the X-axis and Y-axis directions relative to the plate element 13 and thus also regulating the movement and pivoting of the shaft 11. Accordingly, after the movable assembly head 8 stops, a vibration amplitude caused by the pivoting of the nozzle 10 in the X-axis direction is regulated, a vibration amplitude caused by the pivoting of the nozzle 10 in the Y-axis direction is regulated, and the vibration of the nozzle 10 converges rapidly.
[0036] Although the Fig. 7 and Fig.Figure 8 shows that the first guide recess 22 is the wall surface 13c and the second guide recess 23 is the connecting surface 13e when the plate element 13 is moved in the positive direction of the X-axis. However, the present disclosure is not limited to this. When the plate element 13 is moved in the negative direction of the X-axis, the wall surface and the connecting surface 13e are arranged opposite those in the positive direction. That is, when the plate element 13 is moved in the negative direction of the X-axis, the first guide recess 22 serves as the wall surface 13d and the second guide recess 23 as the connecting surface 13e, which is connected to the wall surface 13d.
[0037] In this way, the position of the first guide receptacle 22 relative to the block element 20, which is enclosed in the lifting unit 14, is fixed. When the nozzle 10 moves up and down, the block element 20 moves up and down in a state in which the first guide receptacle 22 is pre-tensioned by the first guide 15 and the second guide receptacle 23 is pre-tensioned by the second guide 16.
[0038] That is, the plate element 13, the first guide 15, the second guide 16, the block element 20, the first guide receptacle 22, and the second guide receptacle 23 form a vibration control unit 27, which regulates the vibration of the nozzle 10. The component intake unit 9 comprises the nozzle 10, the lifting unit 14, and the vibration control unit 27.
[0039] In this way, in the component assembly device 1 according to the present embodiment, the block element 20 is provided on each shaft 11, and the block element 20 itself is pivotable about the axis (axis 11a) of the shaft 11. By arranging the bearing BR of the block element 20 in a direction perpendicular to the axis 11a of the shaft 11, it is possible to limit the movement of the shaft 11 and to prevent rotation of the shaft 11 in the X-axis direction. Since, in addition, the block end 20d is provided on the section of the block element 20 and abuts the plate element 13, it is also possible to regulate the movement of the shaft and to prevent rotation of the shaft in the Y-axis direction.
[0040] When the plate element 13 is attached to the mounting head 8, the rolling bearing BR of the block element 20 of the shaft 11 is located within the groove 13a. By moving (displacing) the plate element 13 in the X-axis direction after positioning the plate element 13 along the Y-axis direction, the bearing BR, which is located in the space of the groove 13a, is preloaded (pressed) in the X-axis direction. When the bearing BR is preloaded in the X-direction, the block element 20 rotates about the axis of the shaft 11 as its pivot point, and the block end 20d comes into contact with the convex section (connecting surface 13e) outside the groove 13a of the plate element 13 and is preloaded. The amount by which the plate element 13 is displaced in the X-direction can be adjusted according to the desired preload in the XY plane.
[0041] By providing the plate element 13 in the component assembly device 1, it is possible to limit the vibration of the shaft 11 in the X and Y directions (on the XY plane) and to reduce the amplitude of the mounting head 8 (nozzle 10) in the X and Y directions. In the component assembly device 1, applying a preload to the plate element 13 also applies a preload to the block element 20 and the shaft 11, thereby reducing the vibration of the shaft 11 and the nozzle 10 mounted on the shaft 11 on the XY plane. Therefore, the component assembly device 1 can mount a component with the nozzle 10 with less vibration, thus improving installation accuracy. <Overview of embodiments of the present disclosure>
[0042] As described above, the present disclosure describes at least the following points. Components corresponding to those in the embodiment above are indicated in parentheses, but the present disclosure is not limited thereto. (Point 1)
[0043] A component assembly device (component assembly device 1) comprises: a nozzle (nozzle 10) provided on a tip end section of a shaft (shaft 11) and configured to mount a component picked up by a component feeder (component feeder 4) onto a substrate (substrate P); a lifting unit (lifting unit 14) configured to raise and lower the nozzle; and a vibration control unit (vibration control unit 27) configured to regulate the vibration of the nozzle, wherein the vibration control unit includes a block element (block element 20) through which the shaft is inserted, a first guide (first guide 15) which is provided along a lifting and lowering direction (Z-axis direction) in which the nozzle is raised and lowered, a second guide (second guide 16) which is provided along the lifting and lowering direction, a first guide receptacle (first guide receptacle 22) which is provided on the block element and is in contact with the first guide, and a second guide receptacle (second guide receptacle 23) which is provided on the block element and is in contact with the second guide, and wherein a first plane (first plane H1) intersects a second plane (second plane H2) along a contact surface (wall surface 13c) on which the first guide receptacle is in contact with the first guide, along a contact surface (connecting surface 13e) on which the second guide receptacle is in contact with the second guide.
[0044] An inertial force generated by the nozzle's movement during component assembly acts on the nozzle. For this reason, the inertial force can continue to act on the nozzle even after the assembly head 8 has ceased moving. In contrast, in the component assembly device, the first guide receptacle of the block element, through which the shaft connected to the nozzle is inserted, remains in contact with the first guide even after the nozzle's movement has ceased. This allows the nozzle's movement to be regulated in a direction (X-axis direction) connecting the first guide receptacle and the first guide.Furthermore, in the component assembly device, the second guide recess of the block element, through which the shaft connected to the nozzle is inserted, remains in contact with the second guide even after the nozzle has ceased its movement. This allows the nozzle's movement to be regulated in the direction (Y-axis direction) connecting the second guide recess and the second guide. Therefore, the component assembly device can reduce the residual nozzle vibration on a two-dimensional plane (XY plane) that occurs after the nozzle's movement has stopped. (Point 2)
[0045] In the component assembly device according to point 1 The first guide is arranged in a state in which it is pre-tensioned towards the first guide.
[0046] Accordingly, the component assembly device can further regulate the movement of the nozzle in the direction (Y-axis direction) that connects the first guide receptacle and the first guide, and further reduce the vibration of the nozzle in this direction. (Point 3)
[0047] In the component assembly device according to point 2 The block element is held in such a way that it can pivot about an axis (axis 11a) of the shaft, and In the state where the first guide receptacle is pre-tensioned towards the first guide, the block element pivots around the axis of the shaft, thereby pre-tensioning the second guide towards the second guide receptacle.
[0048] Accordingly, the component assembly device can also preload the second guide by pivoting the block element along with the preload of the first guide. Therefore, the nozzle's movement in the direction (Y-axis direction) connecting the second guide receptacle and the second guide can be further regulated, and the nozzle's vibration in this direction can be further reduced. Consequently, the component assembly device can further reduce the residual nozzle vibration on the two-dimensional plane (XY plane) that occurs after the nozzle's movement has stopped. (Point 4)
[0049] In the component assembly device according to one of points 1 to 3 The vibration control unit comprises a plate element (plate element 13) with a groove (groove 13a) in a side surface, wherein the groove extends along the lifting and lowering direction, The plate element includes the first guide and the second guide, The first guide is one of two wall surfaces (wall surfaces 13c, 13d) that form the groove, and The second guide is a connecting surface (connecting surface 13e) that connects adjacent wall surfaces of adjacent grooves.
[0050] Accordingly, the component assembly device can reduce the residual vibration of the nozzle by providing the first guide and the second guide with a simple configuration. (Point 5)
