Description

Technical Field

[0001] The technology disclosed in this specification relates to a component supply device that supplies components to a component mounting machine for mounting components on a substrate.

Background Art

[0002] Conventionally, as an example of a component supply device that supplies components to a component mounting machine, there is known one provided with a tray pallet on which a tray holding components can be placed. In general, a JEDEC (Joint Electron Device Engineering Council) tray is used as the tray used in the component supply device. The JEDEC tray has a rectangular shape in plan view with a pair of long sides and a pair of short sides, and ears are provided protruding from each of the pair of short sides. One of each pair of ears is offset to one long side along the direction in which the short side extends with respect to the other.

[0003] Also, in order to prevent misplacement of the JEDEC tray, in the conventional technology shown in FIG. 9, dedicated magnet plates having concavities and convexities matching the shape of the ears 102 (specifically, "reference side magnet plate 103" and "dependent side magnet plate 104") are arranged on the reference (component mounting machine) side and the dependent (operator) side of the tray pallet 101. Thereby, the tray 105 is positioned. When the orientation of the ear 102 is incorrect, the position of the ear 102 and the position of the concavities and convexities of the magnet plate do not match, and the tray 105 cannot be normally mounted, so that an incorrect orientation can be detected. Also, as a related technology, for example, what is disclosed in Patent Document 1 has been conventionally known.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional technology shown in Figure 9, if the operator makes a mistake in the layout of the magnet plates, for example, if the reference magnet plate 103 is removed (see Figure 10) or if only the dependent magnet plates 104 are used on both sides of the tray pallet 101 (see Figure 11), the tray 105 can still be attached to the tray pallet 101 even if the orientation of the tabs 102 is incorrect. Therefore, there is a problem in that the misplacement of the tray 105 cannot be prevented. Accordingly, this specification provides a technology for preventing the misplacement of trays. [Means for solving the problem]

[0006] This specification discloses a component supply device. This component supply device supplies components to a component mounting machine that mounts components onto a substrate, and comprises a tray pallet and a tray positioning device. The tray pallet has a rectangular positioning surface on which a plurality of trays holding components can be arranged side by side. The tray positioning device is detachably fixed to the positioning surface of the tray pallet and positions the plurality of trays on the positioning surface. The trays are rectangular in plan view, having a pair of long sides and a pair of short sides, with tabs protruding from each of the pair of short sides. The tray positioning device has a mispositioning prevention mechanism to prevent the tabs from being oriented incorrectly when placing the trays on the positioning surface. Therefore, with the above configuration, the mispositioning prevention mechanism prevents the tabs from being oriented incorrectly, making it physically impossible to misposition the trays. As a result, mispositioning of the trays can be prevented. [Brief explanation of the drawing]

[0008] In the component supply device disclosed herein, the ears protruding from each of the pair of short sides may be offset to one of the long sides along the direction in which the short sides extend. The misplacement prevention mechanism is a recess into which the ears can be fitted, and the recess may allow the ears to be fitted when the orientation of the ears is correct, enabling the tray to be placed on the placement surface, and may not allow the ears to be fitted when the orientation of the ears is incorrect, making it impossible to place the tray on the placement surface. With such a configuration, it is possible to prevent the tray from being placed incorrectly by using a recess into which the ears can be fitted.

[0009] In the component supply device disclosed herein, the tray pallet may have four side walls at positions corresponding to the four sides of the rectangular arrangement surface. The tray arranger includes a plate-shaped arranger body, and the arranger body may be fixed to the arrangement surface in such a manner that it can abut against three of the four side walls. With such a configuration, the arranger body can be positioned in an appropriate position relative to the tray pallet by abutting it against three of the side walls.

[0010] In the component supply device disclosed herein, the placement device body may be fixed only to the second end of the pallet, which is located opposite the first end of the pallet that is positioned on the component mounting machine side of the tray pallet. With this configuration, by fixing the placement device body only to the second end of the pallet, it is possible to prevent the placement device body from being mispositioned and to improve the work efficiency of the tray placement operation.

[0011] In the component supply device disclosed herein, the tray placement device may position multiple trays in a row. The misplacement prevention mechanism may be provided at multiple locations on the placement device body and may be recesses into which the tabs of the multiple trays arranged in a row can be fitted. The multiple recesses may allow the tabs to fit together when the orientation of the tabs is correct, enabling the trays to be placed on the placement surface, and may not allow the tabs to fit together when the orientation of the tabs is incorrect, making it impossible to place the trays on the placement surface. With such a configuration, multiple trays can be properly placed on a tray pallet.

[0012] In the component supply device disclosed herein, the lugs may protrude in the direction in which the longer side extends. The dimension of the recess in the direction in which the longer side extends may be greater than the amount of protrusion of the lugs, and the depth of the recess may be greater than the dimension of the lugs in the depth direction. With such a configuration, the worker can use the recess to grip the lugs that fit into the recess, thereby improving the worker's work efficiency.

[0013] In the component supply device disclosed in this specification, the misplacement prevention mechanism may be a convex portion provided on the placement tool body. The convex portion may enable the tray to be placed on the placement surface when the orientation of the ear portion is correct, and may prevent the tray from being placed on the front surface when the orientation of the ear portion is incorrect. Even with such a configuration, it is possible to prevent the tray from being misplaced.

[0014] In the component supply device disclosed in this specification, the tray may be positioned by abutting one of a pair of long sides against the side wall of the tray pallet. According to such a configuration, by using the side wall of the tray pallet, the tray can be appropriately positioned with respect to the tray pallet.

[0015] (Example) Hereinafter, the component supply device of this embodiment will be described with reference to the drawings. As shown in FIG. 1, the component supply device 10 is a device that supplies the component 2 to the component mounting machine 11 that mounts the component 2 on the substrate 1. The component mounting machine 11 includes a substrate transfer device 12, a parts camera 13, a head unit 21, an XY robot 31, a pallet holding unit 14, a control device 41, and the like. Specific examples of the component 2 include, for example, semiconductor packages such as QFP (Quad Flat Package) and BGA (Ball Grid Array), and chip components such as chip resistors and chip capacitors.

[0016] The substrate transfer device 12 is a device that performs operations of loading the substrate 1 into the working position P1 in the component mounting machine 11, positioning the substrate 1 before component mounting at the working position P1, and unloading the substrate 1 after component mounting from the working position P1. The substrate transfer device 12 of this embodiment can be configured by, for example, a pair of belt conveyors, a support device (not shown) that is attached to the belt conveyor and supports the substrate 1 from below, and a drive device (not shown) that drives the belt conveyor.

[0017] The component camera 13 is provided between the substrate transfer device 12 and the pallet holding unit 14, at a position below the movement path of the head unit 21. The component camera 13 images the component 2 adsorbed by the head unit 21 from below. The component camera 13 is configured using an imaging device such as a CMOS (Complementary Metal Oxide Semiconductor) or a CCD (Charge Coupled Device), for example.

[0018] The head unit 21 includes a mounting head 22 and a mark camera 24. The mounting head 22 is attached to the lower surface side of the head unit 21 and is for performing the operation of mounting the component 2 on the substrate 1. The mounting head 22 also includes a plurality of suction nozzles 23. Each suction nozzle 23 is moved up and down in the vertical direction (Z-axis direction) by an actuator (not shown) housed in the mounting head 22 and is configured to be able to adsorb the component 2.

[0019] To mount the component 2 on the substrate 1 by the head unit 21, first, the suction nozzle 23 is moved downward until the suction surface of the suction nozzle 23 abuts against the component 2 of the tray pallet 51 held by the pallet holding unit 14. Next, the component 2 is adsorbed by the suction nozzle 23, and the suction nozzle 23 is moved upward. When the process of adsorbing the component 2 by the suction nozzle 23 is completed, the XY robot 31 is driven to position the head unit 21 with respect to the substrate 1. Then, the component 2 is mounted on the substrate 1 by lowering the suction nozzle 23 toward the substrate 1.

[0020] The mark camera 24 is mounted in the head unit 21 in the vicinity of the mounting head 22 and is configured to be movable together with the mounting head 22. The mark camera 24 moves above the substrate 1 carried into the working position P1 by the substrate transfer device 12 and images a mark (not shown) attached to the substrate 1. The mark camera 24 is configured using an imaging device such as a CMOS or a CCD, for example.

[0021] The XY robot 31 moves the head unit 21 between the top of the tray pallet 51 and the top of the substrate 1 by moving the head unit 21 in the X and Y directions. The XY robot 31 consists of guide rails that guide the head unit 21, a moving mechanism that moves the head unit 21 along the guide rails, and motors that drive the moving mechanism.

[0022] The pallet holding unit 14 is located on the operator side (below in Figure 1) of the substrate transport device 12 and the parts camera 13. The pallet holding unit 14 holds the tray pallet 51 that has been supplied into the component mounting machine 11. The pallet holding unit 14 is equipped with detection means such as a mass sensor, and is capable of detecting the supply of the tray pallet 51.

[0023] As shown in Figures 1 and 2, the parts supply device 10 includes a loader 15, a tray pallet 51, and a magnetic plate 71 (an example of a tray placement device). The loader 15 is located at the operator-side end of the parts mounting machine 11 and takes one tray from each of the tray pallets 51 housed in multiple slots of a stocker (not shown) and moves it to the pallet holding unit 14.

[0024] The tray pallet 51 is made of a soft magnetic material such as iron and has a rectangular placement surface 52 on which two trays 61 and 62 can be placed side by side (left and right in Figures 1 and 2). The tray pallet 51 also has a first pallet end 53 located on the component mounting machine 11 side (upper side in Figures 1 and 2) and a second pallet end 54 located on the opposite side of the first pallet end 53 (lower side in Figures 1 and 2). Furthermore, the tray pallet 51 has four side walls 55, 56, 57, and 58 at positions corresponding to the four sides of the placement surface 52. Each of the side walls 55 to 58 protrudes upward from the four edges of the placement surface 52, and when viewed from above, the whole structure forms a rectangular frame.

[0025] Furthermore, the trays 61 and 62 in this embodiment are JEDEC (Joint Electron Device Engineering Council) trays. Trays 61 and 62 have a rectangular shape in plan view, with a pair of long sides 63 and 64 and a pair of short sides 65 and 66. Multiple components 2 are held in trays 61 and 62. Each component 2 is arranged vertically and horizontally in the planar direction (in this embodiment, 10 vertical columns × 4 horizontal columns).

[0026] Furthermore, each of the trays 61 and 62 has a pair of short sides 65 and 66, each having ears 67 and 68 protruding from them. Ear 67 protrudes from the short side 65 in the direction of extension of the long sides 63 and 64 (specifically, towards the first end 53 of the pallet), and ear 68 protrudes from the short side 66 in the direction of extension of the long sides 63 and 64 (specifically, towards the second end 54 of the pallet). That is, both ears 67 and 68 protrude in opposite directions and have the same shape and size. Also, both ears 67 and 68 are offset towards one of the long sides 63 (to the left in Figure 2) along the direction of extension of the short sides 65 and 66. Furthermore, both ears 67 and 68 are offset in the same direction (to the left in Figure 2) along the direction of extension of the short sides 65 and 66.

[0027] As shown in Figures 1 to 4, the magnetic plate 71 is detachably fixed to the placement surface 52 of the tray pallet 51 by the magnetic force of the magnetic plate 71. The magnetic plate 71 is a component for positioning the two trays 61 and 62 side by side on the placement surface 52. The magnetic plate 71 also includes a plate-shaped plate body 72 (placement device body) with a permanent magnet embedded in it. The plate body 72 is fixed to the placement surface 52 in such a way that it can contact three of the four side walls 55 to 58 of the tray pallet 51, namely 56 to 58. In other words, the plate body 72 is fixed only to the pallet second end 54 side of the pallet first end 53 and pallet second end 54 side.

[0028] Furthermore, the magnetic plate 71 has recesses 73 (an example of a part constituting the mis-placement prevention mechanism) to prevent the orientation of the tabs 67 and 68 when placing the trays 61 and 62 on the placement surface 52. The recesses 73 are provided in two places on the plate body 72 and open on the pallet first end 53 side. The tabs 68 of the two trays 61 and 62 that are placed side by side can be fitted into each of the two recesses 73. Specifically, the two recesses 73 are arranged so that when the two trays 61 and 62 are correctly placed on the placement surface 52 of the tray pallet 51, the tabs 68 of the two trays 61 and 62 fit into each of the two recesses 73. As described above, the tabs 67 and 68 of the trays 61 and 62 are offset to one of the longer sides 63. Therefore, the recess 73 that fits into the ear portion 68 of tray 61 (the recess 73 on the left in Figure 2) is offset towards the long side 63 of tray 61, and the recess 73 that fits into the ear portion 68 of tray 62 (the recess 73 on the right in Figure 2) is offset towards the long side 63 of tray 62. Furthermore, the dimension L1 (see Figure 3) in the direction in which the long sides 63 and 64 of the recess 73 extend is greater than the amount of protrusion L2 (see Figure 3) of the ear portion 68, for example, it is between 2 and 5 times the amount of protrusion L2. In addition, the depth L3 (see Figure 4) of the recess 73 is greater than the dimension L4 (see Figure 4) in the depth direction of the ear portions 67 and 68, for example, it is between 3 and 10 times the dimension L4. Note that both ear portions 67 and 68 are offset towards the surfaces 61a and 62a of trays 61 and 62 from the center in the thickness direction of the recess 73 (see Figure 4).

[0029] As shown in Figures 2 and 3, the magnetic plate 71 has a protrusion 74 (an example of a part constituting the mis-placement prevention mechanism) to prevent the orientation of the tabs 67 and 68 when placing the trays 61 and 62 on the placement surface 52. The protrusion 74 is provided between the two recesses 73 on the plate body 72 and extends from the plate body 72 toward the pallet first end 53.

[0030] Next, we will explain how to arrange trays 61 and 62 on tray pallet 51.

[0031] First, the worker places the magnetic plate 71 on the placement surface 52 of the tray pallet 51. At this time, the plate body 72 of the magnetic plate 71 is fixed to the placement surface 52 in contact with the three side walls 56 to 58 of the tray pallet 51. The magnetic plate 71 is fixed to the placement surface 52 of the tray pallet 51, which is made of a soft magnetic material such as iron, by the magnetic force of the magnetic plate 71.

[0032] Subsequently, the worker places the trays 61 and 62 on the placement surface 52 of the tray pallet 51 to which the magnetic plate 71 is fixed. Specifically, tray 61 is positioned by placing one of its pair of long sides 63 and 64, long side 63, against the side wall 56 of the tray pallet 51, and the tip of the tab 67 (upper end in Figure 2) against the side wall 55 of the tray pallet 51. Similarly, tray 62 is positioned by placing one of its pair of long sides 63 and 64, long side 64, against the side wall 58 of the tray pallet 51, and the tip of the tab 67 against the side wall 55.

[0033] In this case, the two recesses 73 of the magnetic plate 71 allow the ear portions 67 and 68 on the trays 61 and 62 to fit together when their orientation is correct, enabling the trays 61 and 62 to be placed on the placement surface 52. On the other hand, if the front and back sides of the trays 61 and 62 are reversed, causing the orientation of the ear portions 67 and 68 to be incorrect, the ear portion 67 will rest on the plate body 72. As a result, the two recesses 73 do not allow the ear portion 67 to fit together, making it impossible to place the trays 61 and 62 on the placement surface 52 (see Figure 5).

[0034] Furthermore, when placing trays 61 and 62, the left side surface 75 of the protrusion 74 comes into contact with the long side 64 of tray 61, and the right side surface 76 of the protrusion 74 comes into contact with the long side 63 of tray 62, thereby positioning the trays 61 and 62. The protrusion 74 allows the ears 68 to fit into the recess 73 when the orientation of the ears 67 and 68 is correct, and also allows the sides 75 and 76 to come into contact with the long sides 63 and 64, thus enabling the placement of trays 61 and 62 on the placement surface 52. On the other hand, if the front and back sides of trays 61 and 62 are reversed, resulting in the incorrect orientation of the ears 67 and 68, the ears 67 cannot fit into the recess 73 when the sides 75 and 76 come into contact with the long sides 63 and 64. As a result, the protrusion 74 makes it impossible to place trays 61 and 62 on the placement surface 52. Furthermore, if the front and back of the tray 61 are reversed and the ear portion 67 is fitted into the recess 73, the tray 61 will be separated from the protrusion 74, and the end of the tray 61 on the long side 64 will rest on the side wall 56 of the tray pallet 51, making it impossible to position the tray 61 on the placement surface 52. Similarly, if the front and back of the tray 62 are reversed and the ear portion 67 is fitted into the recess 73, the end of the tray 62 on the long side 64 will rest on the protrusion 74, making it impossible to position the tray 62 on the placement surface 52.

[0035] From the above, the worker can know that trays 61 and 62 are incorrectly placed if they become unable to be placed. At this time, the worker can check the tray pallet 51 and correct the placement of trays 61 and 62.

[0036] In the parts supply device 10 of this embodiment, a magnetic plate 71 is detachably fixed to the placement surface 52 of the tray pallet 51, and the magnetic plate 71 positions a plurality of trays 61, 62 on the placement surface 52. The trays 61, 62 have tabs 67, 68 protruding from a pair of short sides 65, 66, respectively, and the magnetic plate 71 has a recess 73 to prevent the orientation of the tabs 67, 68 when placing the trays 61, 62 on the placement surface 52. Because the recess 73 prevents the orientation of the tabs 67, 68 from being incorrect, it becomes physically impossible to place the trays 61, 62 incorrectly. As a result, misplacement of the trays 61, 62 can be prevented, and the work efficiency of the tray placement work can be improved.

[0037] In conventional parts supply devices, one reference magnet plate 103 and two dependent magnet plates 104 were arranged on the tray pallet 101 (see Figure 9). On the other hand, in the parts supply device 10 of this embodiment, only one magnet plate 71 is arranged on the tray pallet 51. As a result, the number of parts in the parts supply device 10 can be reduced, and the device cost can be reduced.

[0038] In the component supply device 10 of this embodiment, the plate body 72 of the magnet plate 71 is fixed to the placement surface 52 in contact with the three side walls 56 to 58 of the tray pallet 51. As a result, the left end surface 77 (see Figure 2) of the plate body 72 contacts the side wall 56, and the right end surface 78 (see Figure 2) of the plate body 72 contacts the side wall 78, thereby preventing the magnet plate 72 (plate body 72) from rattling laterally.

[0039] In the parts supply device 10 of this embodiment, the plate body 72 of the magnet plate 71 is fixed only to the second end 54 of the tray pallet 51, out of the first end 53 and the second end 54 of the tray pallet 51. As a result, since the magnet plate 71 is located on the front side of the tray pallet 51, the operator can easily perform tasks such as fitting the ears 68 of the trays 61 and 62 into the recesses 73, and bringing the long sides 63 and 64 of the trays 61 and 62 into contact with the sides 75 and 76 of the protrusions 74.

[0040] In the parts supply device 10 of this embodiment, the dimension L1 (see Figure 3) in the direction in which the long sides 63 and 64 of the recess 73 extend is greater than the amount of protrusion L2 (see Figure 3) of the ear portion 68 of the trays 61 and 62, for example, it is more than twice but less than or equal to five times the amount of protrusion L2. As a result, a space is created between the bottom surface of the recess 73 and the tip of the ear portion 68 (the lower end in Figure 3) into which the worker's finger can be inserted. By hooking the finger inserted into the space onto the ear portion 68, the trays 61 and 62 can be easily removed from the magnetic plate 71.

[0041] Although the embodiments have been described in detail above, the specific configuration is not limited to the embodiments described above. In the embodiments described above, the ear portions 67 and 68 protruding from the pair of short sides 65 and 66 of the trays 61 and 62 were offset to one of the long sides 63 (the left side in Figure 2) along the direction in which the short sides 65 and 66 extend, but the configuration is not limited to this. For example, in other embodiments, the ear portions 67 and 68 may be offset to the other long side 64 (the right side in Figure 2) along the direction in which the short sides 65 and 66 extend. Also, the ear portions 67 and 68 may be offset in opposite directions. Furthermore, the offset amounts of the ear portions 67 and 68 may be different from each other. Note that the ear portion 67 on the side that does not fit into the recess 73 of the magnet plate 71 does not need to be offset in particular.

[0042] In the above embodiment, the parts supply device 10 was equipped with a tray pallet 51 on which two trays 61 and 62 could be placed side by side, but the configuration is not limited to this. For example, in another embodiment, the parts supply device 10 may be equipped with a tray pallet 82 (see Figure 6) on which three trays 81 could be placed side by side, or it may be equipped with a tray pallet on which four or more trays could be placed side by side.

[0043] In the above embodiment, the plate body 72 of the magnet plate 71 was fixed only to the second end 54 of the tray pallet 51, which is located closer to the user than the first end 53 of the pallet. However, the configuration is not limited to this. For example, in another embodiment, the plate body 72 may be fixed only to the first end 53 of the pallet, which is located on the side of the component mounting machine 11.

[0044] In the above embodiment, the recesses 73 and protrusions 74 of the magnetic plate 71 were used as a misplacement prevention mechanism, but the configuration is not limited to this. For example, in other embodiments, a plurality of pins 93 (see Figure 7) that protrude vertically from the surface 92 of the magnetic plate 91 (tray holder) may be used as a misplacement prevention mechanism. The distance between pairs of pins 93 that contact each tray 61, 62 corresponds to the dimension in the direction in which the short side 66 of the ear portion 68 extends. Alternatively, a plurality of pins 96 (see Figure 8) that protrude vertically from the side surface 95 (top surface in Figure 8) of the magnetic plate 94 (tray holder) may be used as a misplacement prevention mechanism. The distance between pairs of pins 96 that contact each tray 61, 62 corresponds to the dimension in the direction in which the short side 66 of the ear portion 68 extends.

[0045] In the above embodiment, the magnet plate 71 had a plate-shaped plate body 72 with a permanent magnet embedded in it, but the configuration is not limited to this. For example, in other embodiments, the magnet plate may have a plate body with a sheet-shaped permanent magnet attached to its back surface, or a plate body formed from a permanent magnet. In other embodiments, the magnet plate 71 may be changed to a plate (tray holder) made of a soft magnetic material such as iron that does not generate a magnetic field, and the tray pallet 51 may be changed to a structure that includes a hard magnetic material such as a permanent magnet that generates a magnetic field. Furthermore, both the magnet plate 71 and the tray pallet 51 may have a structure that includes a hard magnetic material that generates a magnetic field. In other embodiments, the magnet plate 71 may be changed to one that can be detachably fixed to the tray pallet 51 by means other than a permanent magnet. For example, the magnet plate 71 may be changed to a plate (tray holder) having a plate body with hook-and-loop fastener (Velcro) attached to its back surface, or to a locking device (tray holder) provided with a locking part that locks onto the tray pallet 51.

[0046] In the above embodiment, a loader 15 for moving the tray pallet 51 to the pallet holding section 14 was provided at the operator-side end (lower side in Figure 1) of the component mounting machine 11, but the configuration is not limited to this. For example, in other embodiments, the loader 15 may be omitted, and the tray pallet 51 may be placed on the pallet holding section 14 in advance.

[0047] Although specific examples of the present invention have been described in detail above, these are merely illustrative and do not limit the scope of the claims. The technologies described in the claims include various modifications and changes to the specific examples illustrated above. The technical elements described in this specification or drawings exhibit technical usefulness individually or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
