Description

  The present invention finishes wafer processing in the previous process, replaces devices such as LEDs, semiconductor devices, etc., classified according to characteristics and pasted on the adhesive sheet for each classification, to other adhesive sheets for processing in the subsequent process. The present invention relates to a pasting apparatus and a classification pasting method.

  Devices such as LED chips and semiconductor devices are shipped after being subjected to wafer processing in the previous process, and then subjected to wafer mounting, die bonding, wire bonding, and packaging in the subsequent process.

  The method of supplying the device from the previous process to the subsequent process includes a method of supplying a device attached to a wafer sheet having adhesiveness on the wafer ring (such as a UV sheet) and separated into pieces by dicing, There are a method in which a device is mounted on a lead frame and supplied by a lead frame supply unit, or a method in which the device is supplied in a predetermined direction and orientation by a vibratory parts feeder.

  Among these, in the method of supplying a device by a wafer sheet, the quality inspection of the device on the wafer sheet is performed as the last process of the previous process. For example, in the case of an LED chip, an optical test such as luminous intensity, luminous flux, wavelength, and color coordinates is performed using an optical probe, and an appearance inspection is performed using a camera. In the case of a semiconductor device, appearance inspection, electrical characteristic inspection, and the like are performed. Such various inspections reveal the device characteristics of each device, and the devices may be classified into a plurality of classifications before reaching the subsequent process according to such device characteristics.

  As such a method of classifying devices on a wafer sheet, for example, there is one shown in FIG. In other words, one wafer ring in which devices separated by dicing are attached to a wafer sheet, and a plurality of wafer rings in accordance with the number of classifications for reattaching the classified devices for each classification, Prepare. In this technique, a plurality of wafer rings are classified and reattached from the single wafer ring according to the result of characteristic inspection. In this case, since a wafer ring can be prepared for each classification, delivery to a subsequent process is facilitated. In this re-sticking wafer sheet, devices are arranged, for example, in a rectangular shape for each classification.

  However, in the above-described method of classifying and re-applying a plurality of wafer rings according to the result of the characteristic inspection from one wafer ring, since one wafer ring is normally classified into one classification, the number of classifications is an apparatus number. The number of wafer rings that can be installed as a whole is limited. That is, the number of wafer rings mounted is limited by the size of the apparatus, and a large number of classifications cannot be secured. Further, when a plurality of wafer rings are arranged, the operating range of a mechanism for performing reattachment from one wafer ring is widened, and processing time per operation is increased, resulting in poor productivity. Further, the area occupied by the apparatus is relatively large.

  As another method, for example, a plurality of prepared wafer rings are arranged so as to be overlapped in the vertical direction, and the wafer ring is switched, for example, by pulling out the target wafer ring and reattaching it according to the classification. By doing so, it is possible to secure a large number of classifications. However, in this case, it takes time to switch the wafer ring, and productivity is lowered. Further, a wafer ring switching mechanism and a storage mechanism are required, the apparatus configuration is complicated, and the occupied area of the apparatus is increased.

  Therefore, as a method for solving this, the applicant prepares a plurality of 2-inch trays (for example, Gel Pack (trademark)) to which an adhesive sheet is attached as shown in FIG. A sorting apparatus has been proposed in which a plurality of trays are arranged in a circular shape to form a drum shape, and devices are attached to the plurality of trays arranged on the drum for each classification (PCT / JP2009 / 002342). ).

  In this classification apparatus, devices are classified and pasted on a plurality (60 in the embodiment) of 2-inch trays arranged on the drum, and then the trays on which the devices are pasted are stored in magazines for each classification. It is like that.

  With such a classification device, while occupying a large number of classifications, the area occupied by the device including the drive mechanism is suppressed, and even if the number of device classifications is large, the drum can be rotated and moved axially. High-speed switching is possible, and productivity is increased. Further, even when the device is full on each tray, only the tray needs to be replaced, and the time required for the replacement can be shortened very much.

  By the way, in the sorter as described above, in order to perform high-speed processing to multiple sorts, a smaller tray that is generally used, for example, a 2-inch type tray, is used. If it is not compatible with the bonder supply mechanism that performs the above process, it cannot be transferred to the subsequent process as it is. In this case, it is necessary to replace the 2-inch type tray with a commonly used adhesive sheet of about 20 cm square.

  Conventionally, various such pasting apparatuses have been proposed. For example, while the chip-shaped wafer is supported by the first support, the expanded state is set, and the second support is bonded to the wafer. There is a technique in which one support is heated by a heating means, and the first support 1 is released from the expanded state while being contracted by the heat, and is then pasted from one sheet to the other ( Patent Document 1).

  In addition, after the semiconductor wafer attached to the dicing sheet is divided into individual chips and then temporarily held on the holding sheet, these chips are attached to a pickup sheet having a smooth surface having an interfacial force. In this replacement, a technique has been proposed in which the sheet is irradiated with UV to reduce the adhesive strength of the sheet (Patent Document 2).

Further, a cleaning mechanism 6 for cleaning the surface of the first sheet S1 after being reversed by the tray reversing mechanism 5 and pasting a device on a second sheet described later is provided.

  In this embodiment, the magazine 2 stores a 2-inch (5 cm square) supply tray K in which the first sheet S 1 having adhesiveness is mounted in a plurality of vertical directions, and is driven up and down by the elevator 3. Is done.

  The elevator 3 moves the magazine 2 in the vertical direction and sequentially carries the supply tray K to be discharged to a position of a tray reversing mechanism 5 described later. Specifically, the magazine 2 is fixedly placed. A mounting table 31, a ball screw 32 connected to the mounting table 31 as an element for driving the mounting table, and a motor 33 that rotationally drives the ball screw 32 are provided.

When the device is replaced with the second sheet S2, the reverse motor 52 rotates again by 180 degrees, and it is configured to return to the original receiving position where the supply tray K is received from the magazine 2, and at this returned position, An empty supply tray K is returned to the magazine 2 by the return pusher 42 described above.

  Here, the relationship between the adhesive strengths of the first sheet S1 and the second sheet S2 will be described. For the first sheet S1, for example, a gel sheet is used, and in particular, an adhesive having a weak adhesive strength compared to a normal adhesive sheet is used. On the other hand, for example, a UV sheet having strong adhesive force is used for the second sheet S2. As a specific example, a gel sheet having an adhesive strength of 2 to 3 N / 20 mm is used for the first sheet S1, and an adhesive strength of 5 to 10 N / as a UV sheet before ultraviolet irradiation is used for the second sheet S2.

Further, the protective sheet affixed to the adhesive surface of the second sheet S2 is peeled off from the roller 711, and this protective sheet is wound up by the protective sheet winding roller 8 provided in the lower part. Yes.

  The second sheet S2 whose direction is changed in the horizontal direction by the roller 712 is conveyed with the adhesive surface facing upward by the rotational drive of the feed roller 72 provided downstream from the attaching position of the tray reversing mechanism 5. By controlling the rotation of the feed roller 72, the feed roller 72 is configured to stop at a predetermined position.

  The distance between the roller 712 and the feed roller 72 is substantially the same as the distance between the holding rollers 121 and 112 in the sheet sorting elevator 12 described later, and this is due to the size of the storage shelf 13. The pasting position in the tray reversing mechanism 5 is configured to be the center position of the roller 712 and the feeding roller 72 in the feeding direction of the second sheet S2. That is, this is a configuration for the device to be attached to the center position of the second sheet S2 of 20 cm square stored in the storage shelf 13.

[1-2. Action]
Next, with reference to FIGS. 1 to 5, (1) the process for supplying the tray, and (2) the tray is reversed with respect to the operation of the pasting apparatus 1 of the present embodiment configured as described above. A description will be given by dividing into three aspects of a process for pasting and (3) a process for separating and storing a sheet.

[1-2-1. Process for feeding trays]
In order to supply the tray, the re-sticking device 1 first moves the magazine 2 in the vertical direction by the elevator 3, and the desired supply tray K is the discharge position from the magazine 2. It stops on the same plane as the mounting surface 511 of the five suction hands 51.

  In this state, the discharge pusher 41 of the pusher mechanism 4 inserts a pressing portion in the horizontal direction with respect to the magazine 2 and discharges the supply tray K from the magazine 2 to the suction hand 51 side. The supply tray K discharged from the magazine 2 is sent to the mounting surface of the tray reversing mechanism 5 and sucked and held by the suction hand 51. By such processing, the supply tray K is supplied from the magazine 2 to the tray reversing mechanism 5.

[1-2-2. Processing for reversing and pasting the tray]
In the tray reversing mechanism 5 in which the supply tray K is sucked by the suction hand 51, before the reversing process is performed, as the processing for reversing and reversing the tray, the pasting device 1 first supplies the supply tray K of the tray reversing mechanism 5. The surface inspection camera 141 provided immediately above the receiving position of the device performs an appearance inspection of the device surface affixed on the first sheet S1 mounted on the supply tray K.

  Simultaneously with the appearance inspection, the RFID reader 15 provided in the vicinity of the receiving position of the supply tray K of the tray reversing mechanism 5 reads the identification information relating to the classification stored in the IC tag attached to the supply tray K, and this is read later. The barcode label printer 9 and the control unit of the sheet classification elevator 12 input the barcode representing the classification information on the adhesive sheet in the barcode label printer 9, and the sheet classification elevator 12 stores the second in the storage shelf 13. When the sheet S2 is stored, it is determined in which position of the multistage storage shelf 13 the second sheet S2 is stored.

  Next, the tray reversing mechanism 5 reverses the suction hand 51 around the rotation axis O by the action of the reversing motor 52. At this time, as the feed roller 72 rotates, the second sheet S2 is supplied from the sheet roll 71 provided under the tray reversing mechanism 5. The second sheet S2 is unwound from the sheet roll 71 in a substantially vertical direction, positioned by rollers 711 and 712, and the sheet direction is changed in the horizontal direction. Further, the protective sheet attached to the adhesive surface of the adhesive sheet is peeled off from the roller 711, and this protective sheet is taken up by the protective sheet take-up roller 8 provided in the lower part. The adhesive sheet whose direction is changed in the horizontal direction by the roller 712 is conveyed with the adhesive surface facing upward by the rotational drive of the feed roller 72, and stops at a predetermined position by the rotation control of the feed roller 72.

  In such a state, the reversing motor 52 reverses the supply tray K, and the reversing motor 52 rotates the mounting surface 511 of the suction hand 51 by 180 degrees around the shaft portion 512 as the rotation axis, thereby supplying the supply tray K to the supply tray K. The horizontal position where the held first sheet S1 abuts on the second sheet S2 is maintained.

  Subsequently, the sticking adjustment mechanism 54 is a surface having an area equivalent to the sticking area from the lower surface side of the second sheet S2 from the state of FIG. 5 (a) to the state shown in FIG. 5 (b). By pushing up the sheet, the first sheet S1 and the second sheet S2 of the supply tray K held by the suction hand 51 are sandwiched.

  Specifically, the raising / lowering motor 547 of the sticking adjustment mechanism 54 rotates, and accordingly, the raising / lowering cam 546 rotates, whereby the cradle 545 rises. Then, the support body 544 connected thereto is raised, and accordingly, the silicone gel sheet 541 and the mounting plate 542 are also raised so that the second sheet S2 is pressed from the lower surface by the silicone gel sheet 541. Become. At this time, first, the rising degree of the cradle 545, the support body 544, the silicone gel sheet 541, and the mounting plate 542 is adjusted according to the degree of eccentricity of the lifting cam 546, and the pushing amount from below to the second sheet S2 is adjusted. Second, the silicone gel sheet 541 and the mounting plate 542 are urged in the direction of the second sheet S2 by the pressure adjusting spring 543 provided at the lower portion of the mounting plate 542, so that the first of the silicone gel sheet 541 The contact pressure with respect to the second sheet S2 is adjusted.

  At this time, for the first sheet S1, for example, a gel sheet having an adhesive strength of 2 to 3 N / 20 mm is used, and the second sheet S2 has an adhesive strength of 5 to 10 N / as a UV sheet before ultraviolet irradiation. As in the case of using a 20 mm sheet, an adhesive sheet having a low adhesive strength is used for the first sheet S1 that is an attachment main body, and an adhesive sheet having a strong adhesive force is used for the second sheet S2 that is an adherend. Thus, the suction hand 51 having the above-described configuration is reversed, and the first sheet S1 is pressed against the second sheet S2 while applying an appropriate pressure, so that the device is replaced.

  As described above, when the device replacement operation from the first sheet S1 to the second sheet S2 is completed, the suction hand 51 is again rotated counterclockwise by the reversing motor 52 by 180 degrees, and is supplied from the magazine 2 to the supply tray K. Return to the original receiving position.

  The cleaning mechanism 6 acts at such a position of the suction hand 51. That is, the roller support 62 and the cleaning roller 61 supported at the tip of the roller support 62 are moved from the initial position A to the upper position B by the elevating cylinder 631 and then moved to the first sheet S1 side by the sliding cylinder 632. . At this time, the adhesive tape is pulled out from the adhesive tape roller 64 by the pulling of the sliding cylinder 632. Then, after being moved from the upper position B to a lower position equivalent to the initial position A by the elevating cylinder 631 and installed at the end portion of the first sheet S1, the first sheet S1 is operated by the action of the sliding cylinder 632. The first sheet S1 is cleaned while moving up. At this time, the pressing force of the cleaning roller 61 against the first sheet S 1 is adjusted by the lifting cylinder 632.

  As described above, when the cleaning roller 61 finishes moving on the first sheet S1, the support 62 returns to the initial position A by the action of the elevating cylinder 631 and the sliding cylinder 632. At this time, the adhesive tape usually loosens. Therefore, in this embodiment, such loosening is prevented by rotating the cleaned tape roller 65 by a motor. The torque of the winding motor is kept low enough to remove slack. The cleaned tape roller 65 is provided with a ratchet 651, and the adhesive tape is pulled by the ratchet 651 when the cleaning roller 61 and the roller support 62 are moved by the action of the sliding cylinder 632 during cleaning. As a result, the used adhesive tape is not unwound from the cleaned tape roller 65 by reverse rotation. Note that if the torque of the winding motor is too strong, the entire adhesive tape is wound up regardless of the operation of the cylinder 63, so that an appropriate torque adjustment is required.

  When the cleaning process is completed, the suction hand 51 returns the empty supply tray K to the magazine 2 by the return pusher 42 described above at this returned position. By reversing and repositioning the suction hand 51 as described above, one process is completed, and the suction hand 51 receives the supply tray K from the magazine 2 described above again, reverses it by the reversing motor 52, and replaces it. .

  At this time, the shift mechanism 53 slides in the Y-axis direction in the drawing, which is the width direction with respect to the traveling direction of the second sheet S2 of the suction hand 51. That is, when the suction hand 51 finishes repositioning one device, it moves in the Y-axis direction, which is the width direction of the second sheet S2, to 1 to 4 locations on the second sheet S2, The device is repositioned while reciprocating the receiving position of the supply tray K and the repositioning position by 180 degrees, and then the second sheet S2 is fed by about 5 cm by a later-described feed roller 72, and the suction hand 51 slides again. Then, the device is pasted to 5 to 8 locations on the second sheet S2, the second sheet S2 is sent again 5 cm, the device is pasted to 9 to 12 locations on the second sheet S2, and the second A series of processes of feeding the second sheet S2 by 5 cm and replacing the 13 to 16 places of the second sheet S2 is repeated under the control of the shift mechanism 53 and the feed roller 72.

  Here, when the tray reversing mechanism 5 rotates 180 degrees and returns to the original position, the device that has been replaced from the first sheet S1 on the supply tray K is on the back side of the second sheet S2. Therefore, the appearance of the back side of the device is inspected by the back side inspection camera 142 provided immediately above the repositioning position of the tray reversing mechanism 5.

  When the series of re-sticking processes as described above is completed, the feed roller 72 is rotationally driven to move the second sheet S2 to the downstream side. At this time, in the barcode label printer 9 provided immediately below the feed roller 72, a barcode created based on the classification identification information input from the RFID reader 15 is attached to the second sheet S2 that has been attached again. To do. At the same time, the protective sheet is unwound from the protective sheet roll 10 in accordance with the rotational driving of the feed roller 72, and a protective sheet is applied to a device that is applied to the second sheet S2. That is, the barcode label and the protective sheet are simultaneously attached to the back surface side of the second sheet S2 and the protective sheet to the front surface of the second sheet S2 by sandwiching the feed roller 72. It has become so.

[1-2-3. Processing for separating and storing sheets]
By the rotational driving of the feed roller 72 as described above, the device attached to the second sheet S2 is conveyed to the downstream side and conveyed between the holding rollers 121 and 122 of the sheet sorting elevator 12. At this time, when the arrival of the second sheet S2 is confirmed by the detection means such as a sensor or a camera on the holding roller 122 adjacent to the downstream storage shelf 13, the feeding roller 72 stops the conveyance.

  When it is confirmed that the second sheet S2 is held by the holding roller 122 of the sheet classification elevator 12, and the conveyance of the second sheet S2 by the feed roller 72 is stopped, the sheet cutter provided on the upstream side of the holding roller 121 11 cuts the second sheet S2 in the width direction (Y direction in the figure) at that position.

  The sheet sorting elevator 12 holds the cut 20 cm square second sheet S2 by holding rollers 121 and 112 provided at the front and rear ends, and holds the held second sheet S2 in a predetermined storage shelf 13. In order to insert, it moves up and down by the action of the elevator mechanism. When the sheet classification elevator 12 moves to a predetermined storage shelf 13 position, the holding rollers 121 and 122 of the sheet classification elevator 12 are rotationally driven to send the held second sheet S2 to the storage shelf 13 side. The sheet S2 is stored in the storage shelf 13. After the storage, the sheet sorting elevator 12 returns to the original position, which is the same as the vertical direction of the feed roller 72, and waits for the arrival of the second sheet S2 to be fed next.

[1-3. effect]
According to the pasting device 1 of the present embodiment as described above, the first size of the size that can be used in the subsequent process from the magazine that stores the tray including the first sheet to which the classified device is pasted in multiple stages. By sequentially executing the device replacement on the second sheet, it is possible to realize the replacement between the device sheets by automation, thereby speeding up the processing and improving the convenience. In addition, it is possible to prevent mistakes such as mixing of rods, as compared with manual device replacement.

  The tray reversing mechanism can adjust the pressing amount and the pressing pressure for pressing the device attached to the first sheet on the supply tray against the second sheet, so that the pressure adjustment is performed according to the characteristics of the device. By doing so, the device can be prevented from being damaged, and the first sheet can be reliably replaced with the second sheet.

  In addition, since the protective sheet is pasted on the second sheet on which the device is pasted, the device stored in the storage shelf and then shipped can be prevented from being damaged or soiled. The reliability of products to be shipped can be improved.

  When the device is reversed and replaced by the tray reversal mechanism, it is possible to inspect the appearance of the front and back surfaces of the device, detect device defects before shipping the device, and prevent defective products from being shipped. It becomes.

  Further, by using a pressure-sensitive adhesive sheet having a low adhesive strength for the first sheet that is the main body to be attached and using a pressure-sensitive adhesive sheet having a strong adhesive force for the second sheet that is to be attached, the above-described adsorption By reversing the hand and pressing the first sheet against the second sheet while applying an appropriate pressure, the device can be replaced.

  The tray held by the suction hand by pushing up the sheet from the lower surface side of the second sheet on the surface having the same area as the pasting area at the position where the suction hand is pasted on the second sheet by the pasting adjustment mechanism. By sandwiching the first sheet and the second sheet, the device can be easily replaced from the first sheet to the second sheet. First, the degree of elevation of the sticking adjustment mechanism body is adjusted by adjusting the degree of eccentricity of the lifting cam, and the amount of pressing from the lower side with respect to the second sheet is adjusted, and secondly, the sticking is adjusted by a pressure adjusting spring. It is possible to adjust the contact pressure of the adjustment mechanism with respect to the second sheet.

  In addition, since the tray classification information attached in the classification device can be transferred from the first sheet to the second sheet during a series of automation work, it can be classified according to the characteristics of the device. The product can be shipped and the classification information can be used in the subsequent process.

  A cleaning mechanism is provided, and the adhesive surface of the first sheet that has been pasted to the second sheet is rolled onto the adhesive surface of the first sheet with a pressing roller, and the dirt on the first sheet is transferred to the adhesive tape for cleaning. It is possible to accurately remove the dirt and dust of the device, and it is possible to classify and replace the device by the sheet that always maintains the adhesive force. In particular, the adhesive surface of the first sheet can be cleaned while the cleaning roller is moved by the cylinder, so that dirt and dust on the first sheet can be efficiently removed. In addition, the cleaned tape roller is provided with a ratchet that prevents reverse rotation of the roller, so that the cleaned tape wound around the cleaned tape roller flows backward and attaches dirt to the first sheet. Therefore, it is possible to provide an efficient and highly reliable cleaning mechanism.

  With such a cleaning mechanism, it is possible to perform a cleaning process without requiring a structure or the like for preventing water splashing in the apparatus, which has been used to remove the dirt on the surface of the sheet by washing with water. It is possible to improve.

  With the above-described series of device classification / replacement processing, devices can be classified into a plurality of classifications simultaneously in the classification device, and can also be replaced with the second sheet of the shipping size in the re-assignment device. In addition, when pasting, between both devices, the identification information of the classification that has been manually input conventionally can be inherited by automation, and the user can refer to the classification identification information of the device as barcode information, It becomes easy to ensure device traceability.

  When the device is an LED chip, as the classification identification information, the brightness, chromaticity, and wavelength of the LED can be easily determined by referring to the classification identification information of the device attached to the first and second sheets. Will be able to.

  In addition, by including lot information including the number of devices mounted on the first and second sheets, the lot number, and the date and time of manufacture as classification identification information, the user is affixed to the first and second sheets. By referring to the barcode information, it is possible to refer to the lot information of the device, so that it is easy to ensure the traceability of the device.

[2-3. Action]
[2-3-1. Transfer processing on turntable]
In the previous process, the device assembly is completed, and the device attached to the wafer sheet stretched on the wafer ring is separated into pieces by dicing, and this is picked up by the suction nozzle provided on the turntable T.

  The picked-up device is mounted on a mounting table P provided at a circumferentially equidistant position on the turntable T, and intermittently rotates at a predetermined timing while being sucked and held, and is equidistant from the mounting table P. Then, the sample is sequentially transferred to various inspection devices provided on the upper side of the turntable T. For example, when the device is an LED chip, an optical test such as luminous intensity, luminous flux, wavelength, and color coordinates is performed using an optical probe, or an appearance inspection is performed using a camera.

  By the rotation of the turntable T, a plurality of inspection results are assembled by the control device (not shown) based on the result of the characteristic inspection of the device until the device that has been inspected moves to the receiving position of the pickup nozzle 111. A class is assigned according to the characteristics, and the result is calculated from the position information of the tray 102 corresponding to the class in the drum 101 to calculate the amount of movement of the drum 101, and the position information is input to the drum moving mechanism 104. The

[2-3-2. Receipt processing by pickup nozzle]
When the device moves to the receiving position of the pickup nozzle 111, the pickup nozzle 111 is lowered to the receiving position, which is the mounting table P on the turntable T, by the action of the Z-axis moving mechanism 114, and by the vacuum suction, the mounting table P Pick up a device from

[2-3-3. Delivery paste processing to the tray]
Subsequently, the pickup nozzle 111 moves from the receiving position on the mounting table P on the turntable T to the drum 101 side as the rotary arm 113 rotates 180 degrees by driving the motor M2 fixed by the support plate 112. And move to the delivery paste position to the tray 102.

  At this time, the drum 101 receives the tray 102 corresponding to the classification of the device picked up by the pickup nozzle 111 by driving the drum moving mechanism 104 based on the movement position information of the drum 101 input from a control device (not shown). Theta rotation by the central axis O and movement in the Y-axis direction are performed so as to be located immediately below the delivery and pasting position by the nozzle 111.

  Here, as described in the configuration of the tray 102, about 5000 devices are arranged on the tray 102. At this time, for example, a device is attached to the pickup nozzle 111 in the vicinity of the pickup nozzle 111. By providing images and recognizing empty positions, rows and columns are formed on the tray 102 so that they can be pasted in order (it is also possible to determine whether the device is full on the tray 102 described later) This is done by image recognition.) At this time, by driving the drum moving mechanism 104, the tray 102 is moved in the X-axis and Y-axis directions, that is, in the vertical and horizontal directions as shown in FIG.

  In other words, in other words, the movement for the tray 102 to be attached to be positioned at the uppermost position in the vertical direction of the drum 101 is performed by rotating the drum 101 by θ rotation about the central axis O. Of the five trays 102 located at the top, the tray to be attached is moved by sliding in the Y-axis direction by the drum moving mechanism 104 so that the tray to be attached is positioned directly below the pickup nozzle 111, and In order to attach the devices sequentially in rows and columns in the tray 102 located immediately below the pickup nozzle, the drum moving mechanism 104 performs a small movement in the X-axis direction and the Y-axis direction.

  The drum 101 is moved in the X-axis and Y-axis directions by the action of the drum moving mechanism 104, and the tray 102 corresponding to the classification of the devices held by the pickup nozzle 111 is located immediately below the pickup nozzle 111, When the delivery / pasting position of the device is determined, the pickup nozzle 111 performs a lowering operation by the action of the Z-axis moving mechanism 114 to deliver and paste the device onto the adhesive sheet of the tray 102.

  The transfer process by the turntable T of the device as described above, the reception process by the pickup nozzle 111, and the delivery and pasting process on the tray 102 of the drum 101 are sequentially repeated.

[2-3-4. Tray replacement process]
When the above processing is repeated and a device becomes full on one tray 102, it is recognized by the image, and the position information or ID information of the tray 102 is transferred to the drum moving mechanism 104 and the tray changer 120. Entered.

  Based on this input, the drum moving mechanism 104 first performs O-axis rotation and Y-axis movement so that the tray 102 moves to the position of the tray replacement arm 121 of the tray replacement device 120.

  Subsequently, the tray exchanging device 120 first receives and holds the tray 102 in which the devices are fully loaded by the suction hand 123 from the holding unit 103 of the drum 101, and retracts the suction hand 123 by about 10 mm by the guide cylinder 124, thereby rotating the rotary actuator 125. Rotate 90 degrees downward in the figure (see FIGS. 6B and 6C). Next, the suction hand 123 is again moved 10 mm toward the temporary tray placement stage 127 by the guide cylinder 124, and the tray 102 is transferred to the temporary tray placement stage 127 (see FIG. 8).

  With respect to the tray 102 full of devices placed on the temporary tray placement stage 127, in the RFID reader / writer 130 immediately below the stage 127, device classification information (for example, brightness, chromaticity, wavelength, etc. if the device is an LED). ) Is read, and lot information such as the device quantity on the tray, the lot number, and the production date and time is written. The IC tag information is used in the above-described pasting apparatus.

  Next, the bar-like pusher 128a of the pusher mechanism 128 moves from the back surface of the supply magazine 126a in the Y-axis direction in the figure, whereby the empty tray 102 in the supply magazine 126a is transferred onto the temporary tray placement stage 127. At the same time, the full tray is moved to the storage magazine 126b side (see FIG. 8A).

  When the empty tray 102 is positioned at the delivery position on the temporary tray placement stage 127, the RFID reader / writer 130 directly under the stage 127 reads the classification information of the device read about the full tray 102 (for example, if the device is an LED, the brightness, Chromaticity, wavelength, etc.) are written to this empty tray 102.

  The suction hand 123 picks up the empty tray 102 (see FIG. 8B). When the empty tray 102 is picked up by the suction hand 123, the pusher mechanism 128 further moves to the storage shelf side, and pushes the full tray completely into the storage shelf (see FIG. 8C). In this manner, the empty tray and the full tray are exchanged on one tray temporary placement stage 127, and the tray exchange operation is performed.

  The storage magazine 126b and the supply magazine 126a can store a plurality of trays 102 in multiple stages in the vertical direction. For example, the storage position is determined in advance for each classification, such as every 10 stages, and suction is performed. The elevators 129a and 129b act according to the classification picked up by the hand 123, and the storage magazine 126b and the supply magazine 126a are moved up and down so that the tray 102 corresponding to a predetermined classification can be supplied or stored. Has been.

  Further, the replacement of the tray 102 by the tray replacement device 120 is performed mainly when an arbitrarily set number is attached to one tray 102, in other words, when the device is full on the adhesive tape of the tray 102. Further, when the tray 102 is replaced, the classification operation of the classification device 100 is temporarily stopped. In the present embodiment, the tray 102 replacement operation is performed in a time of 5 seconds or less.

  In addition, the RFID reader / writer 130 writes device classification information to an empty tray of the device, reads the device classification information to a tray full of devices, and the device lot on the tray. Although the information is written, it is not limited to such a configuration. That is, the RFID reader / writer 130 writes device classification information, device information on the tray, lot information such as the lot number / manufacturing date and the like in advance to the empty tray, and receives the full tray when the full tray is received. A configuration is also included in which the classification information and the lot information about the tray are read, and the information is transferred to an empty tray pasted at a predetermined position of the drum 101 in place of the full tray.

[2-4. effect]
According to the classification apparatus 100 of the present embodiment as described above, since each tray 102 is independent for each classification held on the drum 101, it can be individually attached and exchanged for each classification, for example, one classification By filling up, there is no waste that affects other classifications, and productivity can be improved.

  Further, the holding unit 103 is provided on the cylindrical drum 101, and the tray 102 is disposed here, so that a drive mechanism is included while ensuring a very large number of classifications (about 60 classifications in the present embodiment). The area occupied by the apparatus can be reduced. Furthermore, even if the number of device classifications is large, the tray 102 can be switched at high speed by moving in the rotation axis O direction and the Y axis direction, and productivity is very high.

  Therefore, when a plurality of wafer rings are categorized and reattached according to the result of the characteristic inspection, the number of wafer rings is not limited, and reattachment is performed from one wafer ring. Therefore, the drum moving mechanism 21 only needs to move the drum 101 in the directions of the rotation axis, the X axis, and the Y axis, and the operating range of the moving mechanism can be suppressed. As a result, the processing time per operation can be shortened.

  In addition, the tray 102 divided for each classification in the drum 101 is attached to and detached from each tray 102 by the tray exchanging device 120, the tray 102 is stored in the storage magazine 126b for each classification, and a new tray is supplied to the supply magazine 126a. And can be pasted on the drum 101 again.

  Furthermore, when the device is full on the tray 102, only the tray needs to be replaced, and the items necessary for the replacement are also very short (in this embodiment, about 5 seconds). Therefore, when a single classification becomes full as in the case where a plurality of classifications are arranged in a rectangular shape on one wafer sheet, there is no need to switch the ring itself, and there is no waste.

  Further, when replacing the tray, the RFID reader / writer 130 manages the device classification information on the tray by the IC tag by reading and writing the device classification information and the lot information with respect to the IC tag attached to the tray. By using this classification information as it is in the subsequent re-applying apparatus, it becomes easy to ensure the traceability of the device.

  As described above, according to the classification apparatus of the present embodiment, device classification in the previous process can be performed simultaneously in multiple classifications in a simple, high-speed and space-saving manner.

[1. Pasting device]
The present invention is not limited to the configuration shown in the above embodiment, and includes, for example, the following embodiments. That is, the arrangement of the magazine 2, the elevator 3, and the pusher mechanism 4 in the above embodiment is merely an example of the apparatus configuration, and the supply tray K is discharged from the magazine 2 and delivered to the suction hand 51. Any configuration may be employed as long as the pusher mechanism 4 can return the supply tray K from the suction hand 51 to the magazine 2. Specifically, in the above embodiment, the two pieces of pushers of the suction hand 51, the magazine 2, and the pusher mechanism 4 are arranged in the width direction (Y-axis direction in the drawing) of the second sheet S2, but in the present invention, However, the present invention is not limited to this, and the second sheet S2 can be arranged in the feeding direction (X-axis direction in the drawing).

  Further, in the present embodiment, a 2 inch adhesive sheet is used as an example as the first sheet S1, and a 20 cm square adhesive sheet is used as an example as the second sheet S2, but this is only an example, The sizes of the first and second sheets S2 can correspond to various sizes depending on the apparatus specifications and the like.

  Further, in the above-described embodiment, the suction hand 51 can be slid in the Y-axis direction by the shift mechanism 53 as well as reversed by the reversing motor 52. From the first sheet S1, one second sheet is provided. A maximum of 4 × 4 16 locations can be replaced with S2. However, this is merely an example, and the shift mechanism 53 is omitted as an apparatus configuration, and the suction hand 51 is moved only by the reversing operation by the reversing motor 52, and only at one place with respect to the second sheet S2. The present invention also includes embodiments in which affixing is performed or a plurality of points are affixed in the feeding direction of the second sheet S2 by feeding operation by the feeding roller 72.

  Further, the configuration of the sticking adjustment mechanism 54 in the above embodiment is not limited to that shown in the above embodiment. For example, by using a voice coil motor instead of the pressure adjustment spring 543, the second sheet can be used. The electrical load can be adjusted.

[2. Classification device]
In the above embodiment, the rotation axis O of the drum 101 is arranged in the horizontal direction. However, in the present invention, the rotation axis O is not limited to such an aspect, and the rotation axis O is installed in the vertical direction as shown in FIG. It is also possible. In this case, the pickup nozzle 111 in the above-described embodiment rotates the device 90 degrees after picking up the device from the turntable T, and performs a delivery pasting process to the drum 101. The detailed configuration and operation of each of the other devices can be configured in the same manner as in the above embodiment, so that the same effect as in the above embodiment can be obtained.

  Further, in the delivery pasting process to the tray in the above embodiment, the rotation of the center axis O and the Y axis so that the tray 102 is positioned immediately below the delivery pasting position by the pickup nozzle 111 by driving the drum moving mechanism 104. The tray 102 is moved in the X-axis direction and the Y-axis direction when the devices are sequentially attached in rows and columns on the tray 102. For example, the pickup nozzle 111 can be caused to move in the X-axis or Y-axis direction by the drum moving mechanism 104 by changing the configuration of the pickup nozzle 111. That is, the drum 101 itself performs only θ rotation, and the pickup nozzle 111 moves to the tray 102 while moving in the X-axis and Y-axis directions on the predetermined tray 102 of the drum 101 when attaching the device. It is also possible to adopt a configuration in which the above is pasted.

  However, as can be seen from the description of the present embodiment, since the movement range in the Y-axis direction is wide, the movement of the drum 101 by the drum moving mechanism 104 is performed together with the movement of the X-axis and the Y-axis as in the above-described embodiment. Even when the pickup nozzle 111 is assigned to the movement process in the XY direction, at least the movement in the Y-axis direction is the movement of the drum 101, and the pickup nozzle 111 has a fine adjustment in the X-axis direction. A mode in which only movement is performed is preferable from the viewpoint of high-speed processing of the apparatus.

  In the tray replacement structure described above, a full tray is stored in the storage magazine 126b, and an empty tray is supplied from the supply magazine 126a instead of the full tray. For example, a known conveyor is provided at the position of the storage magazine 126b, and an empty tray is pushed out from the supply magazine 126a side onto the temporary tray placement stage 127 by the pusher of the pusher mechanism 128. As a result, the full tray placed on the temporary tray placement stage 127 is moved to the conveyor provided on the opposite side across the supply magazine 126a and the stage 37, loaded by the conveyor, and transferred to a predetermined location by the conveyor. It is good also as such a structure.
