In FIG. 3, the positional relationship of each part is described separately from state 1 to state 4. The operation of each unit described below is performed under the control of the control unit 40.

  In the pickup operation of the electronic component 100, first, the electronic component holding table actuator 12 moves the electronic component holding table 11, and moves the desired electronic component 100 to the pickup position Pu (on the axis indicated by the one-dot broken line).

  At the same time or before and after, the head actuator 32 moves the transfer head 30 and moves the desired suction nozzle 31 to the pickup position Pu (state 1). The positions in the Z direction of the pickup hammer 13, the push-up needle and the suction nozzle 31 in this state are the initial positions in the Z direction.

  Subsequently, the pickup motor 15 rotates the upper disk cam 14 and moves the pickup hammer 13 downward. As the pickup hammer 13 moves, it contacts the upper end of the suction nozzle 31 and then pushes down the suction nozzle 31 against the biasing force of the spring mechanism that biases the suction nozzle 31 upward.

  The suction nozzle 31 pushed down contacts the electronic component 100 at the position where the pickup hammer 13 reaches the lower end of the moving range, and the controller 40 operates the suction of the suction nozzle 31 in order to suck the electronic component 100 in advance. The electronic component 100 is adsorbed. Further, the push-up motor 18 rotates the lower disk cam 17 and moves the push-up needle 16 toward the electronic component 100 (state 2).

  Subsequently, the pickup motor 15 rotates the upper disk cam 14 and moves the pickup hammer 13 upward to release the suction nozzle 31 from being pushed down. The suction nozzle 31 released from being pushed down moves upward while the electronic component 100 is sucked by the biasing force of the spring mechanism. At the same time, the upper end of the push-up needle 16 penetrates the wafer sheet 200 and pushes the electronic component 100 upward, and the lower end of the electronic component 100 is moved in the direction of peeling from the wafer sheet 200 (state 3).

  The pick-up hammer 13 and the push-up needle 16 return to their initial positions, and the suction nozzle 31 that sucks the electronic component 100 to the lower end also returns to the initial position in the Z direction. Thereafter, the electronic component holding table actuator 12 moves the electronic component holding table 11 so that the next electronic component 100 comes to the next pickup position Pu.

By repeating the above-described operation a plurality of times, the electronic component 100 is attracted to each of the plurality of suction nozzles 31 held by the transfer head 30.

  The mounting operation in the mounting unit 20 is performed in the same procedure. A specific procedure will be described below. In the mounting operation of the electronic component 100, first, the mounting board holding base actuator 22 moves the mounting board holding base 21 to move a desired electronic component mounting position on the mounting board 300 to the mounting position Pl. At the same time or before and after, the head actuator 32 moves the transfer head 30 and moves the suction nozzle 31 that sucks the electronic component 100 to the mounting position Pl. At this time, the mounting hammer 23 is in an initial position in the Z direction.

  Subsequently, the mounting motor 25 rotates the disc cam 24 and moves the mounting hammer 23 downward. As the mounting hammer 23 moves, it contacts the upper end of the suction nozzle 31 and then pushes down the suction nozzle 31 against the biasing force of the spring mechanism that biases the suction nozzle 31 upward. The electronic component 100 sucked by the sucked suction nozzle 31 comes into contact with the mounting board 300 at a position where the mounting hammer 23 reaches the lower end of the moving range.

  At this time, the control unit 40 releases the suction of the suction nozzle 31 that sucks the electronic component 100, so that the electronic component 100 is disposed at the electronic component mounting position on the mounting substrate 300. Since the mounting substrate 300 has adhesiveness, the electronic component 100 adheres to the mounting substrate 300 at the electronic component mounting position.

  Subsequently, the mounting motor 25 rotates the disc cam 24 and moves the mounting hammer 23 upward to release the suction nozzle 31 from being pushed down. The suction nozzle 31 released from being pushed down is moved upward in a state where the electronic component 100 is not sucked by the biasing force of the spring mechanism.

  After the mounting hammer 23 returns to the initial position and the suction nozzle 31 that has finished the arrangement of the electronic component 100 also returns to the initial position in the Z direction, the mounting board holding base actuator 22 moves the mounting board holding base 21 and the mounting position Pl Move the next mounting position.

At this time, the mounting hammer 23 is in an initial position in the Z direction.

  Subsequently, the mounting motor 25 rotates the disc cam 24 and moves the mounting hammer 23 downward. As the mounting hammer 23 moves, it contacts the upper end of the suction nozzle 31 and then pushes down the suction nozzle 31 against the biasing force of the spring mechanism that biases the suction nozzle 31 upward. The remaining electronic component sucked by the sucked suction nozzle 31 comes into contact with the rearrangement unit 400 at a position where the mounting hammer 23 reaches the lower end of the moving range.

  At this time, the controller 40 cancels the suction of the suction nozzle 31 that sucks the remaining electronic components, so that the remaining electronic components are arranged at a desired electronic component rearrangement position on the rearrangement unit 400. Since the rearrangement unit 400 has adhesiveness, the remaining electronic components adhere to the rearrangement unit 400 at a desired electronic component rearrangement position.

  Subsequently, the mounting motor 25 rotates the disc cam 24 and moves the mounting hammer 23 upward to release the suction nozzle 31 from being pushed down. The suction nozzle 31 released from being pushed down moves upward in a state in which the remaining electronic components are not sucked by the biasing force of the spring mechanism.

  After the mounting hammer 23 returns to the initial position and the suction nozzle 31 that has finished the arrangement of the remaining electronic components also returns to the initial position in the Z direction, the mounting board holding base actuator 22 moves the mounting board holding base 21 to reposition the position. The next rearrangement position is moved to Pr.

  At the same time or before and after, the head actuator 32 moves the transfer head 30 and moves the suction nozzle 31 that sucks the next remaining electronic component to the rearrangement position Pr.

  As described above, the remaining electronic components transferred by the transfer head 30 are arranged on the rearrangement unit 400 by the operation described above. By repeating the above-described operation a plurality of times, the remaining electronic components that are respectively sucked by the plurality of suction nozzles 31 provided in the transfer head 30 are arranged on the rearrangement 400.

  Next, the camera 19 of the pickup unit 10 captures images of all the electronic components 100 arranged on the wafer sheet 200 and transmits image information to the control unit 40. Based on the transmitted image information, the control unit 40 includes an index on the wafer sheet 200 and electronic component information acquired from the electronic component information storage unit 41 (rank information and position information of the electronic component 100 on the wafer sheet 200). ) Is matched against the index included.

  The control unit 40 sets the coordinates for each electronic component 100 based on the position information of the electronic component information (including rank information and position information) whose collation is matched and the image information captured by the camera 19, and is generated. Link the location information. Thereby, the control unit 40 can recognize the position and rank of the electronic component 100 arranged on the wafer sheet 200. The electronic component information storage unit 41 acquires electronic component information from the storage unit of the probe inspection apparatus in the previous process or the storage unit on the server (step S3).

  Subsequently, the control unit 40 acquires array information (including rank information and position information) of the electronic component 100 mounted on the mounting board 300 from the array information storage unit 42 (step S4).

  The control unit 40 generates a control signal from the electronic component information and the arrangement information and transmits it to each actuator (step S5).

  Next, the control unit 40 moves the transfer head 30 to the pickup unit 10 (step S6) and executes a pickup operation (step S7).

  By such a pickup operation, the electronic component 100 arranged on the wafer sheet 200 is sucked by each of the plurality of suction nozzles 31 of the transfer head 30. The pickup operation will be described later.

  Subsequently, the control unit 40 moves the transfer head 30 to the mounting unit 20 (step S8), and executes a mounting operation (step S9).

  With this mounting operation, the electronic component 100 sucked by each of the plurality of suction nozzles 31 in the transfer head 30 is mounted on the mounting substrate 300. The mounting operation will be described later.

  The control unit 40 repeats a series of operations from step S6 to step S9 until all the electronic components 100 to be mounted on the wafer sheet 200 are mounted on the mounting substrate 300 (step S10: Yes). When all the electronic components 100 to be mounted are mounted on the mounting substrate 300, the control unit 40 receives a signal indicating that the mounting has been completed.

  Further, the control unit 40 can receive the forced rearrangement signal and forcibly place the electronic component 100 on the wafer sheet as the remaining electronic component in the rearrangement unit 400 (not shown in FIG. 4). . This forced rearrangement signal can be received in any of the steps 6-9, and immediately after reception, the electronic component 100 on the wafer sheet is placed in the rearrangement unit 400 as a remaining electronic component.

  When all the electronic components 100 to be mounted on the wafer sheet 200 are mounted, the remaining electronic components remain arranged on the wafer sheet 200.

  When all the electronic components 100 to be mounted are mounted on the mounting substrate 300, the control unit 40 confirms the presence or absence of remaining electronic components from the electronic component information that has already been matched. Furthermore, the presence or absence of remaining electronic components whose collations on the wafer sheet 200 do not match can be confirmed from the image captured by the camera 19 again (step S11). As a result of checking the remaining electronic components, if there are no remaining electronic components, there is no electronic component 100 to be rearranged (step S11: No), and the process ends.

  When the remaining electronic components are confirmed on the wafer sheet 200 (step S11: Yes), the control unit 40 moves the transfer head 30 to the pickup unit 10 (step S12) and executes a pickup operation (step S13). ).

  By such a pickup operation, the remaining electronic components held on the wafer sheet 200 are sucked by each of the plurality of suction nozzles 31 in the transfer head 30. The pickup operation is performed in the same manner as in step 7.

  Subsequently, the control unit 40 moves the transfer head 30 to the mounting unit 20 (step S14), and executes a rearrangement operation (step S15).

  With this rearrangement operation, the remaining electronic components sucked by each of the plurality of suction nozzles 31 in the transfer head 30 are rearranged to the rearrangement unit 400. The rearrangement operation will be described later.

  The control unit 40 repeats a series of operations from step S12 to step S15 until the rearrangement is completed (step S16: Yes). In the rearrangement unit 400, the defective electronic parts and the remaining electronic parts made up of non-defective electronic parts having ranks 304C are arranged in the rearrangement unit 400, except for defective products including unknown rank products.

  In addition, defective products including unknown rank products may be left as they are on the wafer sheet 200, and only non-defective electronic components remaining on the wafer sheet 200 may be arranged as remaining electronic components for each rank in the rearrangement unit. . In this case, the control unit 40 recognizes only the non-defective electronic components remaining on the wafer sheet 200 as remaining electronic components, and controls each actuator.

  A wafer sheet holding process for holding a wafer sheet in which a plurality of electronic components having different ranks are arranged in a wafer shape on the electronic component holding table corresponds to step S1.

  The electronic component information storage step of storing electronic component information including position information of electronic components on the wafer sheet in the electronic component holding table and rank information of electronic components in the electronic component information storage unit corresponds to step S3.

  The sequence information storage step of storing the sequence information of the electronic components in the layout unit in the sequence information storage unit corresponds to step S4.

  The transfer process of taking out one or more electronic components from the wafer sheet and transferring them to the placement unit corresponds to step S6-9.

  Based on the electronic component information and the arrangement information, the electronic component is transferred to a predetermined position in the arrangement unit, and the electronic component transfer unit is controlled to transfer the remaining electronic component remaining on the wafer sheet to the relocation unit. The control process corresponds to step S12-15.

  FIG. 5 is a flowchart showing the flow of the pickup operation of this embodiment. Next, the pickup operation (step 7 in FIG. 4) of the electronic component 100 by the pickup unit 10 of the electronic component transfer apparatus 1 will be described with reference to the flowchart in FIG.

  First, the control unit 40 sets the electronic component 100 to be picked up first as a reference electronic component. The camera 19 captures an image of the reference electronic component and transmits image information to the control unit 40. Based on the transmitted image information, the control unit 40 sets coordinates again for the reference electronic component, and generates position information (step S101).

  The control unit 40 first compares the position information of all the electronic components 100 acquired from the image captured by the camera 19 (step S3 in FIG. 4) with the position information of the reference electronic component newly acquired, and determines the reference It detects how much the position of the electronic component is deviated from the initial position (that is, detected in step S3), and calculates a position correction amount for correcting the deviation (step S102).

  The control unit 40 updates the position information of the stored reference electronic component by applying the newly acquired position information of the reference electronic component (step S103).

  Next, the control unit 40 operates the electronic component holding table actuator 12 based on the updated position information of the reference electronic component, and moves the electronic component holding table 11 so that the reference electronic component is moved to the pickup position Pu. (Step S104).

  At the same time or before and after, the control unit 40 operates the head actuator 32 to move the transfer head 30 so that the suction nozzle 31 that is not sucking the electronic component 100 is moved to the pickup position Pu (step). S105).

  Subsequently, the control unit 40 causes the suction nozzle 31 to suck the reference electronic component and picks up the electronic component 100 (step S106).

  Specifically, the control unit 40 drives the pickup motor 15 to cause the pickup hammer 13 to push down the suction nozzle 31. At the same time, the control unit 40 drives the push-up motor 18 to push the electronic component 100 up by the push-up needle 16.

  The electronic component 100 is adsorbed by contact with the suction nozzle 31 pushed down by the pickup hammer 13, and further, the suction nozzle 31 moves upward and is pushed up by the push-up needle 16, so that the electronic component 100 is peeled off from the wafer sheet 200. Picked up.

  Next, when there is an electronic component 100 that can be picked up (step S107: Yes) and there is a suction nozzle 31 that can suck the electronic component 100 (step S108: Yes), the next electronic component 100 pickups are made.

  The control unit 40 reads the position information stored for the next electronic component 100, and compares the coordinates of the electronic component 100 with the coordinates of the reference electronic component before update (that is, the coordinates detected in step S3). Then, it is determined whether or not the position of the electronic component 100 is within the correction amount application area.

  The correction amount application area indicates a predetermined range starting from the position coordinates of the reference electronic component. Within the correction amount application area, for each electronic component 100, from the detection of the first electronic component 100 position (ie, step S3 in FIG. 4) to the re-detection of the position of the reference electronic component (ie, step S101 in FIG. 5). It can be considered that the positional deviation generated between and is the same.

  The displacement of the position of the electronic component 100 is a major factor due to the expansion and contraction of the wafer sheet 200 to be stretched, and it is considered that the displacement of the position is the same for the electronic component 100 within a certain range.

  If the electronic component to be picked up is present in the correction amount application area after the reference electronic component is picked up, the position shift of the electronic component is considered to be the same as the position shift of the reference electronic component. It is done. For this reason, by detecting the coordinates of the electronic component and acquiring the position information again, the position information after the deviation of the electronic component to be picked up can be obtained by applying the correction amount of the reference electronic component. It can be calculated.

  The predetermined range centering on the reference electronic component that defines the correction amount application area may be changed as appropriate, for example, depending on the stretchability of the wafer sheet 200 that causes the positional shift of the electronic component 100. May be changed as appropriate.

  When the position of the next electronic component 100 is within the correction amount application area with reference to the reference electronic component (step S109: Yes), the control unit 40 uses the position correction amount of the reference electronic component to use the electronic component 100. Is corrected (step S110).

  Specifically, the corrected position information is obtained by applying the position correction amount of the reference electronic component to the stored position information of the electronic component 100.

  The control unit 40 operates the electronic component holding table actuator 12 based on the corrected position information of the next electronic component 100 and moves the electronic component holding table 11 so that the electronic component 100 is moved to the pickup position Pu. Move (step S111).

  Subsequently, the next suction nozzle 31 that is not sucking the electronic component 100 is moved to the pickup position Pu (step S105), and the next electronic component 100 is picked up.

  On the other hand, when the position of the next electronic component 100 is outside the correction amount application area based on the reference electronic component (step S109: No), the control unit 40 sets the electronic component 100 as a new reference electronic component. .

  For the new reference electronic component, the control unit 40 acquires position information by capturing an image (step S101), calculates a position correction amount (step S102), and updates the position information (step S103). Execute pickup operation.

  As described above, according to the configuration described above, the suction operation of the electronic components 100 arranged on the wafer sheet 200 can be continuously performed for the plurality of suction nozzles 31 held by the transfer head 30. For this reason, a plurality of electronic components 100 can be collectively transferred to the mounting unit 20 by a single movement of the transfer head 30.

  In the electronic component transfer apparatus 1, a pickup position Pu that is a position where the electronic component 100 is taken out is determined, and the suction nozzle 31 and the electronic component 100 are transferred to the pickup position Pu one by one in order. For this reason, positioning can be performed in a relatively short time, and the tact time can be shortened.

  In addition, the tact time can be further shortened by transferring the electronic component 100 and the suction nozzle 31 in parallel. Moreover, the electronic components 100 can be sorted by appropriately selecting the electronic components 100 to be sucked according to the state, shape, and rank of the electronic components 100.

  FIG. 6 is a flowchart showing the flow of the mounting operation of this embodiment. Next, the mounting operation (step 9 in FIG. 4) of the electronic component 100 by the mounting unit 20 of the electronic component transfer apparatus 1 will be described with reference to the flowchart in FIG.

  The control unit 40 transmits a control signal for operating the mounting board holding base actuator 22 based on coordinates or the like set in advance on the mounting board holding base 21 according to the arrangement information, and a desired electronic component on the mounting board 300 The mounting board holder 21 is moved so that the mounting position is moved to the mounting position Pl (step S201).

  At the same time or before and after, the control unit 40 operates the head actuator 32 to move the transfer head 30 so that the suction nozzle 31 that sucks the electronic component 100 is moved to the mounting position Pl (step). S202).

  Subsequently, the control unit 40 releases the suction so that the electronic component 100 sucked by the suction nozzle 31 is mounted at the electronic component mounting position on the mounting board 300 (step S203).

  Specifically, the control unit 40 drives the mounting motor 25 to cause the mounting hammer 23 to push down the suction nozzle 31. After the electronic component 100 attracted by the pushed-down suction nozzle 31 comes into contact with the mounting substrate 300, the control unit 40 releases the suction of the suction nozzle 31 and places the electronic component 100 on the mounting substrate 300. To implement.

  Next, the control unit 40 repeats a series of operations from step S201 to step S203 until there is no electronic component sucked by the suction nozzle 31 provided in the transfer head 30 (step S204: Yes). Make it.

  Whether or not an electronic component is present in the suction nozzle 31 is determined by the control unit 40 when the number to be transferred matches the number transferred on the image captured by the camera 26. It can be assumed that no electronic component is present in the nozzle 31.

  When all the electronic components 100 sucked by the suction nozzle 31 are mounted on the mounting substrate 300 (No in step S204), the mounting operation is finished.

  FIG. 7 is a flowchart showing the flow of the rearrangement operation of the present embodiment. Next, the rearrangement operation (step 15 in FIG. 4) of the remaining electronic components by the mounting unit 20 of the electronic component transfer apparatus 1 will be described with reference to the flowchart in FIG.

  The control unit 40 transmits a control signal for operating the mounting board holding table actuator 22 based on coordinates set in advance on the mounting board holding table 21, and the desired electronic component rearrangement position on the rearrangement unit 400 is determined. The mounting board holder 21 is moved so as to be moved to the rearrangement position Pr (step S301).

  At the same time or before and after, the control unit 40 operates the head actuator 32 to move the transfer head 30 so that the suction nozzle 31 that sucks the remaining electronic components is moved to the rearrangement position Pr ( Step S302).

  Subsequently, the control unit 40 releases the suction so that the remaining electronic component sucked by the suction nozzle 31 is placed at the electronic component rearrangement position on the rearrangement unit 400 (step S303).

  Specifically, the control unit 40 drives the mounting motor 25 to cause the mounting hammer 23 to push down the suction nozzle 31. After the remaining electronic component sucked by the pressed suction nozzle 31 comes into contact with the rearrangement 400, the control unit 40 releases the suction of the suction nozzle 31 and rearranges the remaining electronic component on the rearrangement 400. Place in position.

  Next, the control unit 40 performs a series of operations from step S301 to step S303 until there is no remaining electronic component sucked by the suction nozzle 31 provided in the transfer head 30 (step S304: Yes). Let it repeat.

  Whether or not an electronic component is present in the suction nozzle 31 is determined by the control unit 40 when the number to be transferred matches the number transferred on the image captured by the camera 26. It can be assumed that no electronic component is present in the nozzle 31.

  When all the remaining electronic components that are attracted to the suction nozzle 31 are placed in the rearrangement 400 (step S304: No), the rearrangement operation ends.

  Next, with reference to FIGS. 8 and 9, the mounting from the wafer sheet onto the substrate and the arrangement on the rearrangement portion when the light emitting diode element is applied as the electronic component will be described. In addition, about the transfer by the electronic component transfer apparatus 1, mounting and rearrangement, since the structure and operation | movement mentioned above are applicable as they are, description is abbreviate | omitted.

  FIG. 8 shows an example of a light emitting diode element on a wafer sheet and a light emitting diode module mounted on a substrate. Here, the electronic component 100 is a light emitting diode element, and the mounting substrate 300 is a substrate on which a light emitting diode element can be mounted as a substrate of a light emitting diode module, such as a ceramic substrate or a glass substrate.

  The light emitting diode elements on the wafer sheet 200 are received in a state where the quality varies due to the manufacturing conditions in the manufacturing process of the light emitting diode elements in the previous process. This variation in quality is an unavoidable variation in manufacturing caused by the atmosphere in the chamber at the time of manufacturing the light emitting diode, the cleaning of the light emitting diode element, the variation in the film thickness of the light emitting diode element, and the like. If a product or a module is manufactured without taking this variation into consideration, variations will occur in the finished product, and the yield will eventually deteriorate.

  Therefore, each light emitting diode element is inspected by probe inspection or the like, and ranking is performed according to the inspection result. The wafer sheet in FIG. 8 schematically shows the inspection results, where ◯ is an A rank light emitting diode element, ● is a B rank light emitting diode element, × is a C rank light emitting diode element, and ■ is a defective element. Is shown. Actually, there are several tens of ranks, but in the description of the present embodiment, description will be made with three ranks. Even if the rank becomes several tens of ranks, the present invention can be applied.

  This inspection result and rank classification information are linked to the position information, and stored in the storage unit of the inspection apparatus on the server or in the previous process together with the index number or code of the wafer sheet attached to each sheet. . Or you may make it store directly in the electronic component information storage part 41. FIG.

  The electronic component information storage unit 41 acquires electronic component information from the inspection device in the previous process or the storage unit. On the other hand, in the array information storage unit 42, array information that is information on the rank and position of the light emitting diode elements to be mounted on the substrate is input.

  The array information includes, for example, information necessary for ranking such as light intensity (lux), light quantity, and wavelength of the light-emitting diode elements, rank information that is previously ranked according to this information, and position information. .

  The rank information and position information in the light emitting diode module will be specifically described. A description will be given with reference to a state 3 in which the light emitting diode module is completed through the mounting process of each rank on the mounting substrate in FIG.

  In the case of a light emitting diode module, it is not necessary that all light emitting diode elements used in the module have the highest rank. This is because the module is only required to be manufactured within an allowable range in terms of specifications because the amount of light and intensity of the module are less varied as a result.

  For this reason, light emitting diode elements of ranks other than the highest rank are mounted on the light emitting diode module. However, there is a restriction depending on the specification of the light emitting diode module, such that the end portion may be required to have a relatively high rank due to the contrast, and the center portion may have a low rank.

  In the light emitting diode module in the state 3 in FIG. 8, the A rank which is the highest rank is used at the end portion, and the end is mounted so as to adopt a lower rank as going to the center. In other words, the C rank is mounted around the lower rank, the B rank is surrounded by the rank, and the A rank is surrounded by the rank so that the luminous intensity and the light quantity of the entire module are secured.

  As described above, a plurality of patterns are prepared from the idea that light emitting diode elements having a necessary rank are mounted at appropriate positions according to specifications required for the final product. Therefore, for example, when a plurality of substrates are held on the mounting substrate holding base 21 of the mounting unit 20, they can be mounted on the plurality of substrates with the same arrangement pattern or with different patterns. It becomes possible.

  The control unit 40 refers to the electronic component information according to the arrangement information, calculates which position on the wafer sheet 200, which rank of the light-emitting diode element is picked up and mounted on the substrate, and holds the electronic component Control signals are transmitted to the table actuator 12, the mounting substrate holder actuator 22, and the transfer head 30.

  Thereby, the light emitting diode element is picked up from the wafer sheet 200 by the suction nozzle 31 of the transfer head 30 and mounted on the substrate.

  For example, in FIG. 8, the light emitting diode element with the highest rank A among the light emitting diode elements to be mounted is first mounted on the substrate on one substrate arranged on the mounting substrate holding base 21 ( State 1).

  Next, the B rank light emitting diode element is picked up from the wafer sheet 200 (state 2) and mounted. Finally, the C rank light emitting diode element is picked up from the wafer sheet 200 and mounted (state 3).

  It should be noted that the mounted electronic components may be inspected after mounting the light emitting diode elements of each rank at the time of mounting. By performing such inspection after mounting each rank, the tact time can be shortened, and when inspection is performed from many light emitting diode elements on the wafer sheet 200 such as A rank, inspection after mounting A rank When a problem is detected in the above, mounting on the board is stopped, and it is possible to prevent unnecessary use of B rank or C rank light emitting diode elements which are fewer electronic components.

  Further, the inspection may be performed for each substrate after completion of mounting on the substrate. The inspection is performed based on an image captured by the camera 26 of the mounting unit 20.

In the image picked up by the camera 26, each light emitting diode element is present at a position where it should be, or is mounted at a certain distance from another light emitting diode element at a position where it should be, or obliquely or horizontally. Check whether it is not mounted.

  In the description of FIG. 8, it has been described that the mounting is performed from the light emitting diode element of rank A that is mounted most on the substrate, but the mounting order is not limited to this, and the rank that is mounted the least on the substrate. The light emitting diode elements may be mounted from the light emitting diode elements having the highest rank on the wafer sheet 200 or the light emitting diode elements having the smallest rank.

  FIG. 9 shows an example of the remaining light emitting diode elements remaining on the wafer sheet after mounting the light emitting diode elements to be mounted and the remaining light emitting diode elements disposed in the rearrangement unit 400. Next, with reference to FIG. 9, the arrangement | positioning to the rearrangement part 400 of the remaining light emitting diode element which remained on the wafer sheet | seat is demonstrated.

  The control unit 40 mounts the light emitting diode elements on the mounting substrate 300 according to the arrangement information, and confirms the presence or absence of remaining electronic components from the electronic component information that has already been matched after mounting. Furthermore, the presence or absence of remaining electronic components whose collations on the wafer sheet 200 do not match is confirmed from the image captured by the camera 19. Thereafter, the mounting is completed for all the set mounting boards 300. Next, the control unit 40 confirms the light emitting diode elements remaining on the wafer sheet 200 from the image captured by the camera 19.

  The control unit 40 arranges the remaining light emitting diode elements in the rearrangement unit 400. For example, as shown by the rearrangement unit 400 drawn on the right side of FIG. 9, a defective element indicated by ■, an A rank light emitting diode element indicated by ○, a B rank light emitting diode element indicated by ●, C rank light emitting diode elements indicated by x are arranged.

  As described above, the light emitting diode elements on the rearrangement unit 400 can be easily used by arranging the rearrangement unit 400 regularly. Further, when the rearrangement unit 400 is provided separately from the substrate, it is also easy to move the rearrangement unit 400 and cause the pickup unit 10 to hold it again.

  In this embodiment, defective elements including unknown rank elements are also arranged in the rearrangement unit 400. However, defective elements including unknown rank elements are discarded, so that they are left as they are on the wafer sheet 200. It is preferable that only non-defective light emitting diode elements are regularly arranged in the rearrangement unit 400.

  The pick-up of the electronic component 100 and the remaining electronic components on the wafer sheet 200 is not limited to a plurality of pick-ups, but one pick-up nozzle 31 is formed on the transfer head 30 and may be picked up one by one. A single nozzle formed on the transfer head 30 is used to complete the individual substrates by mounting the electronic components 100 one by one in the rank order for each substrate, or to the plurality of mounting substrates 300 on the mounting substrate holder 21. On the other hand, mounting on a plurality of substrates can be completed by mounting in rank order.

  In the present embodiment, as an example, the rearrangement unit 400 is provided on the same plane as the mounting substrate holding base 21 provided with the mounting substrate 300 as the arrangement unit, and the remaining electronic components are arranged in the rearrangement unit 400. Alternatively, a part of the arrangement wafer sheet to be transferred may be used as a rearrangement unit, and the remaining electronic components may be transferred to a part of the wafer sheet arranged in the pickup unit.

  In addition, one or more of the plurality of mounting boards 300 can be used as the rearrangement unit 400. The rearrangement unit 400 is preferably configured to be separately pickable, and position information and rank information regarding the electronic components 100 of each rank arranged in the rearrangement unit 400 are stored so that they can be used separately. Stored in the department.

<Definition part>
In the present invention, a light emitting diode element is used as an example of an electronic component. However, for example, a semiconductor element, a resistance element, a transistor, or the like may be used, and any electronic component that can be divided into a plurality of ranks depending on its property. Any electronic component may be used.

  In the present invention, the substrate is, for example, a substrate such as a ceramic substrate, a glass substrate, or a printed substrate, and may be any substrate that can mount electronic components.

  In the present invention, the electronic component information is, for example, position information of each light emitting diode element including an index on a wafer sheet, and rank information including information such as a light amount and a wavelength. The rank information may be rank information that is divided into predetermined ranks based on information such as light quantity and wavelength. The electronic component information storage unit is connected to a storage device external to the electronic component mounting apparatus, for example, a storage unit of the probe inspection apparatus in the previous process, or the probe inspection apparatus, in addition to the storage unit of the electronic component mounting apparatus.
