Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a supply device for determining and aligning the front and back of a lid used in a crystal oscillator or a crystal filter.
[0002]
[Prior art]
Today, crystal oscillators or crystal filters are used in mobile communication devices such as mobile phones, OA devices such as personal computers, and other various electronic devices, and are the source of reference signals. A crystal oscillator or a crystal filter used for such an application has a structure in which a crystal resonator or a drive circuit for driving the crystal resonator is stored in a housing. The lid of this housing is generally called a lid. In the manufacturing process of the crystal oscillator or the crystal filter, processes for aligning the lids and determining the front and back sides have occurred. Conventionally, this process has been performed by a parts feeder (part alignment supply device).
[0003]
Here, the parts feeder is an apparatus that automatically aligns parts such as machined parts and combined partial metals and supplies them to the next process. The parts feeder aligns the parts in a certain direction by applying a certain vibration to the charged parts (for example, Non-Patent Document 1 and Non-Patent Document 2).
[0004]
Therefore, conventionally, in order to select the front and back of the lid, a method in which the lid is arranged in a certain direction by a parts feeder or a straight feeder using a vibration source is generally used.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an outline of the operation of a front / back discrimination / supply device 1 for a crystal oscillator or crystal filter lid when a front / back reversing operation according to an embodiment of the present invention occurs. First, on the stage 2, there are a plurality of lids R loaded randomly. A camera 7 is installed above the stage 2, and a plurality of lids on the stage 2 are photographed by the camera 7, and the top (top) of the plurality of lids loaded from the photographed images. A certain lid is determined and the lid R is acquired by the pickup unit 6a. The acquired lid R is moved to the stage 3 by the pickup unit 6a (operation of arrow A1).
[0021]
The stage 3 can rotate left and right with respect to a horizontal plane. A camera 8 is installed above the stage 3 so that the lid R on the stage 3 can be photographed. The lid R moved onto the stage 3 is photographed by the camera 8. As a result of the analysis of the captured image, if it is determined that the lid R is not disposed at the fixed position, the stage 3 rotates until the lid R reaches the fixed position.
[0022]
Moreover, the front and back are determined based on the gray scale of the lid R captured from the photographed image. Here, the metal covering the front part of the lid is different from the metal covering the back part, and as a result, the brightness of each surface is different, so that analysis in gray scale is possible.
[0023]
Thereafter, the lid R is acquired by the pickup unit 6b. The acquired lid R is moved to the inverting unit 4 by the pickup unit 6b (operation of arrow A2).
The reversing unit 4 includes a stage 4a and a rotating unit 4b. The rotating part 4b is rotatable around the shaft 4c, and is configured to rotate in the direction of the arrow B1 from the state shown in FIG.
[0024]
The lid is moved from the stage 3 to the reversing unit 4 by the pickup unit 6b. However, when the front / back determination result is the back side (when the lid R on the stage 3 is facing up), the reversing unit 4 It is put on the rotating part 4b. Thereafter, the rotating portion 4b rotates while being in contact with the lid, and the lid R is on the stage 4a after the rotation is completed. And the rotation part 4b returns to the position before rotation again. At this time, the front of the lid on the stage 4a faces upward.
[0025]
The rotation operation of the rotation unit 4b will be further described with reference to FIG. First, the lid R is placed on the rotating portion 4b by the pickup portion 6b (FIG. 2A), and then the rotating portion 4b rotates with the rotating shaft 4c as a fulcrum (FIG. 2 ( b), see FIG. 2 (c)). At this time, the lid R keeps the state of being in contact with the surface of the rotating portion 4b. Here, a suction hole (vacuum chuck) 4d for sucking air is provided on the surface of the rotating portion 4b, and the lid R is rotated by atmospheric pressure by sucking air from the vacuum chuck 4d. It is fixed to the surface of the part 4b.
[0026]
After the rotation portion 4b rotates 180 degrees, the lid R comes into contact with the stage 4a (FIG. 2D). Thereafter, the suction of the suction hole 4d stops, the rotating portion 4b returns to the position before the rotation, and the lid R remains on the stage 4a (FIG. 2 (e)).
Returning to FIG. As described above, the inverted lid R is picked up by the pickup unit 6c and stored in the supply unit 5. The pickup units 6 (6a, 6b, 6c) are indicated by dotted lines C1a-C1b and C2a-. It can move only in the horizontal plane indicated by C2b. Therefore, the following problems occur.
[0027]
FIG. 3 shows the positional relationship between the movement range of the pickup unit and the lid R accompanying the reversing operation. Before reversing the lid R, as shown in FIG. 3A, the lid R is on the rotating portion 4b intersecting the horizontal plane indicated by dotted lines C1a-C1b and C2a-C2b.
[0028]
However, after reversing the lid R (arrow B1), as shown in FIG. 3B, the lid R is on the stage 4a that does not intersect the horizontal plane indicated by the dotted lines C1a-C1b and C2a-C2b. Therefore, the reversing unit 4 is moved in the direction of the arrow B2. That is, the reversing unit 4 is moved to a position where the lid R on the stage 4a intersects the horizontal plane indicated by the dotted lines C1a-C1b and C2a-C2b. FIG.3 (c) shows the inversion part 4 after moving.
[0029]
In the state of FIG. 3C, the pickup unit 6 c can acquire the lid R on the reversing unit 4. In this way, the pickup unit 6c that has acquired the inverted lid R moves to the supply unit 5 (arrow A3 in FIG. 1), and supplies the lid R to the supply unit 5.
[0030]
FIG. 4 shows an outline of the operation of the front / back discrimination / supply device for the crystal oscillator or crystal filter lid when the front / back reversal operation does not occur in the present embodiment. When the front / back determination result on the stage 3 is the front (when the lid R on the stage 3 is facing up), there is no need to invert, so the pickup unit 6b causes the stage 3 to the inversion unit 4 to be reversed. When moving the lid R, it is put on the stage 4a of the reversing unit 4 (arrow A4). At this time, the inversion unit 4 is in the state shown in FIG. 2C, that is, the stage 4a is in a state where it intersects the horizontal plane indicated by the dotted lines C1a-C1b and C2a-C2b.
[0031]
Thereafter, the lid R on the stage 4a is acquired by the pickup unit 6c. The pickup unit 6c moves to the supply unit 5 (arrow A5 in FIG. 1) and supplies the lid R to the supply unit 5.
A magazine, a tray, or the like can be used for the supply unit 5, and these can be exchanged depending on the application.
[0032]
In this manner, the front and back of the lid can be selected without giving vibration to the lid. The present invention will be described in detail below.
[0033]
【Example】
FIG. 5 is a front view of a front / back discrimination / supply device for a crystal oscillator or crystal filter lid according to the present embodiment. In the same figure, the front / back discrimination / supply device 11 (hereinafter referred to as lid front / back discrimination / supply device) for a crystal oscillator or crystal filter lid includes a detection unit 12, a positioning unit 13, an inversion unit 14, a supply unit 15, and a pickup. A unit 16 (16a, 16b, 16c), a detection camera 17, a position camera 18, a detection XY stage 19, an XY stage 20, and a control unit 30 are included.
[0034]
The detection camera 17 is installed on the upper side of the lid front / back discrimination / supply device 11, and photographs the lid R on the stage 12 a on the upper surface of the detection unit 12 installed on the lower side of the lid front / back discrimination / supply device 11. To do.
The position camera 18 is installed on the upper side of the lid front / back discrimination / supply device 11, and the lid R on the stage 13 a on the upper surface of the positioning unit 13 installed at the lower portion of the lid front / back discrimination / supply device 11. Take a picture. The lower part of the stage 13a is fixed to the upper part of the turning positioning part 13b. The turning positioning unit 13b can turn left and right with respect to the horizontal direction of the positioning unit 13. The rotation axes of the stage 13a and the turning positioning unit 13b are coaxial.
[0035]
The reversing unit 14 is for reversing the front and back of the lid R placed on top of the reversing unit 14. The lid R is supplied to the supply unit 15.
The pickup unit 16a can move between the detection unit 12 and the positioning unit 13 in the Xa-Xb direction. The pickup unit 16b can move between the positioning unit 13 and the reversing unit 14 in the Xa-Xb direction. The pickup unit 16c is movable in the Xa-Xb direction between the reversing unit 14 and the supply unit 15.
[0036]
FIG. 6 is a top view of the apparatus in the present embodiment. The detection unit 12 is installed on the detection XY stage 19 and can freely move on the detection XY stage 19 in the Xa-Xb direction and the Ya-Yb direction. Similarly, the supply unit 15 is installed on the XY stage 20 and can freely move on the XY stage 20 in the Xa-Xb direction and the Ya-Yb direction.
[0037]
In this embodiment, the tray 15 is used as the supply unit 15. The tray 15 is composed of two trays 15a and 15b. For example, the tray 15a stores a lid with the front side facing up, and the tray 15b stores a lid with the back side facing up. Use it.
[0038]
Now, the operation of the lid front / back discrimination / supply device 11 will be described in order. First, an ECM search (EdgeCode measurement search, visual sensor F210 manufactured by OMRON Corporation) was previously stored using a detection camera 17 among a plurality of lids randomly placed on a stage (unit) on the detection unit. The detection XY stage 12a scans and searches for a lid equal to the lid area or a lid closest to the previously stored lid area (the largest lid among the detected lids).
[0039]
FIG. 7 shows the lid R detected by the ECM search. In FIG. 7A, the lid Ra is detected, and in FIG. 7B, the lid Rb is detected. In these cases, the edge (contour) of the lid R is detected by the ECM search, and it is determined whether or not the area surrounded by the contour is equal to the area stored in advance. When the areas are equal, it can be determined that the lid is at the top (top) of the plurality of loaded lids. Therefore, the pickup operation by the pickup unit as the next step can be easily performed.
[0040]
In the ECM search process, the operation of adjusting the position of the detection XY stage is also performed. As described above, the pickup unit 16 can move only in the Y direction (left and right direction in FIG. 5) and cannot move in the X direction (perpendicular direction to the drawing in FIG. 5). However, the lid to be picked up within the frame of the detection camera 17 is not detected at a fixed position in the frame (the lid Ra detected in FIG. 7A is positioned to the left of the center of the frame). (The lid Rb detected in FIG. 7B is located below the center of the frame.)
[0041]
Therefore, the detection XY stage 19 is operated so that the pick-up unit 16a can pick up the lid R detected by the detection camera 17, and the lid Rc is detected by the detection camera 17 as shown in FIG. Adjust so that it is in the center of the frame. In addition, while the lid R is detected by the detection camera 17, the pickup unit 16a stands by at the pickup unit standby position P in FIG.
[0042]
Here, the pickup unit 16 will be described. FIG. 8 shows the pickup unit 16 in the present embodiment. FIG. 8A is a top view of the pickup unit 16, FIG. 8B is a front view of the pickup unit 16, and FIG. 8C is a side view of the pickup unit 16. The tip portion 161 of the pickup unit 16 is provided with a suction hole (vacuum chuck) for sucking air, and the lid R is adsorbed to the tip portion 161 by the suction force.
[0043]
Further, since the pickup unit 16 can be moved in the vertical direction, the pickup unit 16 descends from the height position shown in FIG. 5 to the vicinity of the surface of the stage 12a. At this time, since the lid is usually loaded on the stage 12a in the range of 0 to 2.0 (or 2.5) mm, when picking up the lid at the top (top) of the loaded lid, When the only lid is picked up on 12a, the descending width of the pickup unit 16 must be changed.
[0044]
Therefore, as a means for solving this problem, a structure in which the front portion 162 of the pickup unit 16 is variable with respect to the rear portion 163 is employed. That is, a play is provided in the lowered width of the tip portion of the pickup unit. Further, the upper portion of the front portion 162 of the pickup unit 16 and the upper portion 164 of the pickup unit 16 are connected by a spring 165. Furthermore, an extremely lightweight material such as an aluminum alloy is used for the pickup unit.
[0045]
At this time, for example, a case where only one lid is picked up on the stage 12a is set as a reference, and this is set as a descending width. In this case, when the pickup unit 16 is lowered, the tip 161 thereof is in contact with the lid R, so that the lid can be adsorbed by the vacuum chuck.
[0046]
Considering the case of picking up the lid at the top of the loaded lid, the pickup unit 16 descends and comes into contact with the top of the loaded lid before the lowering is finished. Thereafter, when the pickup unit 16 is lowered, only the rear portion 163 of the pickup unit 16 is lowered, and the front portion 162 remains in contact with the top of the loaded lid.
[0047]
At this time, since the front portion 162 of the pickup unit 16 is extremely light, damage to the lid contacting the tip portion 161 can be suppressed as much as possible. Furthermore, an impact can be absorbed by the spring 165.
Thus, after the lid R is detected by the detection camera 17, the lid R is always in the center of the frame of the detection camera 17. Then, the pickup unit 16 a that has been waiting goes to pick up the detected lid R and loads it to the center of the stage 13 a on the positioning unit 13.
[0048]
The lid R placed at the center of the stage 13a on the positioning unit 13 is photographed by the positioning camera 18, and it is determined whether or not the lid R is at a predetermined position (normal position) based on the photographing result. When the lid R is not in the normal position, the stage 13a rotates with respect to the horizontal plane so as to be in the normal position.
[0049]
Along with this normal positioning, the front and back of the lid R are also determined. The front / back determination is performed using a gray scale based on an image captured by the positioning camera 18. In this example, a four-layer clad material composed of different materials on the front and back surfaces (a kovar material on the front and a silver foil on the back (in some cases Au / solder foil)), or Ni plating after press working (in some cases, solder plating) ) Will be used. Accordingly, the metal covering the front surface of the lid R is different from the metal covering the back surface. As a result, the brightness of each surface is different, and discrimination on a gray scale is possible. As the front and back heterogeneous materials, a two-layer clad material using Ag / Cu on one surface and a Kovar material on the other surface, or a four-layer clad material composed of Ni, Kovar, Ag / Cu (for example, Ni, Kv (Kovar) ), Ni, and Ag / Cu are formed in this order). Furthermore, it is also possible to use a lid made of Kovar material and Ni plating, or Kovar material and solder plating.
[0050]
Thereafter, the lid R is picked up by the pickup unit 16 b and sent to the reversing unit 14.
FIG. 9 shows the reversing unit in the present embodiment. 9A is a top view of the reversing unit 14, FIG. 9B is a side view of the reversing unit 14, and FIG. 9C is a front view of the reversing unit 14. The reversing unit 14 includes a stage 14a, a rotating portion 14b, a rotating shaft 14c, a vacuum chuck 14b, an air cylinder 141, and a connector 142.
[0051]
As a result of the front / back determination by the positioning unit 13, if it is determined that the lid is facing up, the lid R picked up by the pickup unit 16b is placed on the stage 14a. Thereafter, it is picked up by the pickup unit 16 c and sent to the supply unit 15.
[0052]
Moreover, when it is determined as a result of the front / back determination by the positioning unit 13 that the lid is facing the back surface, the lid R picked up by the pickup unit 16b is placed on the rotating portion 14b. However, as described with reference to FIG. 3, the pickup unit 16b can move only within a certain range, so here, the reversing unit 14 itself is placed in front of the lid front / back discrimination / supply device 11 in order to place the lid R on the rotating portion 14b. Move in the direction (Yb direction). The reversing unit 14 moves until it contacts the stopper 143.
[0053]
The reversing unit 14 in contact with the stopper 143 stops moving. Then, since the lowering position of the pickup unit 16b is the rotating portion 14b, the pickup unit 16b lowers the lid on the rotating portion 14b. The rotating part 14b rotates around the rotating shaft 14c while sucking the lid by the vacuum chuck. Thereafter, the lid R is placed on the stage 14a.
[0054]
At this time, the expansion / contraction energy in the vertical direction of the air cylinder 141 is transmitted to the rotating portion 14b via the connector 142, and the transmitted energy generates a rotating operation. The connector 142 is for converting the expansion / contraction energy in the vertical direction into rotational energy and transmitting the force to the rotating portion 14b.
[0055]
The reversing unit 14 moves to the original position (moves in the Ya direction) so that the pickup 16c can pick up the lid R placed on the stage 14a. Then, since the lowered position of the pickup unit 16 c is the stage 14 a, the pickup unit 16 c picks up the lid R on the stage 14 a and sends the lid R to the supply unit 15.
[0056]
FIG. 10 shows an example of the supply unit in the present embodiment. FIG. 10A shows a tray-type supply unit. Since the position of the lid supplied by the pickup unit 16c is always the same position, the tray is moved in the XY direction when the XY stage 20 supporting the supply unit 15 is operated so that the lids do not overlap each other. In this way, finally, the lid R is spread on the bottom surface of the tray.
[0057]
FIG. 10B shows a magazine type supply unit. In this case, since the lid R is packed in the magazine, it is not necessary to operate the XY stage 20. FIG. 10C shows a supply unit of a type having two trays (a front tray in which only the lid facing the front is disposed and a back tray in which only the lid facing the rear is disposed). When this tray is used, it is assumed that the reversing mechanism of the reversing unit 14 is not used. That is, in this case, the reversing unit 14 is only a relay point, and if it is determined to be front by the front / back determination, the XY stage is operated so as to be supplied to the front tray 15c-1, and determined to be back by the front / back determination. Then, the XY stage operates so as to be supplied to the back tray 15c-2.
[0058]
Further, depending on the assembly configuration of the lid front / back discrimination / supply device 11 in the present embodiment, the lid R can be directly loaded from the pickup unit 16c to the assembly machine or the assembly line. Thus, it can respond to various supply forms of a lid.
[0059]
In the present embodiment, the detection camera 17 detects the lid, the pickup unit 16 transports the lid, the positioning camera 18 and the positioning unit 13 adjust the front and back of the lid, and controls the reversing mechanism of the reversing unit. Processing such as operation control of the detection XY stage 19, operation control of the XY stage 20, and control of the vacuum chuck is controlled by the control unit 30.
[0060]
FIG. 11 shows an internal outline of the control unit 30 in the present embodiment. In the figure, a control unit 30 includes a central processing unit (CPU) 31, a random access memory (RAM) 32, a read only memory (ROM) 34, a storage device 35, and an output interface (hereinafter, the interface is referred to as I / F) 36. , An input I / F 33, a bus 37 for connecting all of them, an output device 39 connected to the output I / F 36, and an input device 38 connected to the input I / F 33.
[0061]
As the storage device 35, various types of storage devices such as a hard disk and a magnetic disk can be used. A program for performing the processing described above is stored in the storage device 35 or the ROM 34, and such a program is executed by the CPU 31.
[0062]
As the input device 91, a detection camera 17, a positioning camera 18, a keyboard, a mouse, and the like can be used. The output device 90 includes an actuator (for example, a pickup unit 16, a positioning unit 13, a reversing unit 14, a detection XY stage 19, an XY stage 20, a vacuum chuck, etc.) that converts an output result into a mechanical operation, a display Etc. can be used.
[0063]
As described above, it is possible to sort the front and back of the lid in one direction at the same time without applying vibration.
[0064]
【The invention's effect】
The present invention is an apparatus that sorts the front and back of a lid at the same time and rearranges them in one direction without using any vibration source that has been used for lid alignment. By using the apparatus according to the present invention, the falling of the press burr and Ni ball (in some cases, the solder ball), which is the main external factor of the characteristic (natural frequency) change in the assembly process of the crystal oscillator or the crystal filter, Or, it is possible to distinguish the front and back of the lid and to arrange the unidirectional alignment to the tray / magazine while preventing the generation of contamination such as fine dust generated from the parts feeder and fine dust from the factory environment. Further, it can be automatically supplied to an assembly line (in some cases, an assembly machine).
