Description

  Even if splicing is performed during the operation of the component mounting apparatus, the present invention appropriately records the history of the tape reel that is replaced and used when trouble occurs, and the remaining amount of the component in the feeder in which the tape reel is stored The present invention relates to a mounted component management method capable of properly grasping.

  In the component mounting apparatus, a large number of feeders to which reels (hereinafter referred to as “tape reels”) wound with tapes on which components are stuck at a constant pitch are attached are arranged in accordance with the component types. The mounting head of the component mounting apparatus moves to the component suction position of the feeder that supplies the required component, sucks the component by the nozzle, moves to the corresponding position of the board on which the component is mounted, and performs the mounting. To go. Further, in the feeder, the tapes are sequentially sent out along with the suction, and the parts are properly supplied.

  When there is less tape reel remaining in the feeder, this is called splicing, and the tape reel (hereinafter referred to as the old reel or component supply tape reel) of the tape reel being supplied (hereinafter referred to as the old reel or the component supply tape reel) The tip of a tape (hereinafter referred to as a new tape) of a new tape reel (hereinafter referred to as a new reel) is connected.

  That is, in this splicing, the old reel that is currently supplying the part is left on the feeder with the tip of the tape being left in the feeder, and the old reel is removed from the feeder, and the wound tape is loosened. Remove the tail end of the tape. Then, after the tape tip of the new reel is connected to the tail end of the tape, the tape connected to the new reel including the remaining portion of the old tape connected is properly wound, and the new reel is fed to the feeder. Store. Thus, parts can be replenished.

  In the component mounting apparatus, the remaining number of components of each feeder is grasped while subtracting as it is sucked and mounted on the mounting head. When the tape is added to the feeder and a part is added due to the splicing described above, it is necessary to update the remaining part number.

  Further, when mounting a component on a board, a history of which component is supplied from which reel is recorded, and used to investigate the cause when a trouble related to component mounting occurs. In this case, it is necessary to appropriately record the history that the parts supplied from the old reel are supplied from the old reel and the parts supplied from the new reel are supplied from the new reel. There is.

  To automatically detect the splicing old tape and new tape tape connection in the component mounting device in order to update the remaining number of parts and properly record the supply reel history as described above. Various techniques are disclosed.

  For example, a member such as a reflective tape that can be detected by a sensor is attached to the tape connection portion, or a notch is provided, and detection is performed by a sensor attached to each feeder (Patent Document 1 and Patent Document 2). Alternatively, the parts are removed in a fixed pattern around the tape connection part, and the pattern is detected as a pattern of occurrence of an adsorption error by the mounting head (Patent Document 3).

Japanese Patent Laid-Open No. 10-341096 JP 2003-332789 A JP 2004-228442 A

  However, when a sensor is provided for detecting the tape connection portion, it is necessary to provide the sensor in each of a large number of feeders, which causes a problem of cost increase and installation space. Further, the above-described notch causes a problem in the strength of the tape connecting portion.

  In addition, when detecting as a pattern of occurrence of an adsorption error, it is necessary to perform an operation for this in the mounting head, or to link the component mounting apparatus main body and feeder on the mounting head side, and a program for this is required In addition, there is also a problem that the processing efficiency decreases due to an increase in the operation of the entire component mounting apparatus. Furthermore, the suction stability tends to be low in the vicinity of the tape connecting portion, so that there is a possibility of erroneous detection, and there is a problem that parts removed by the pattern are wasted.

  The present invention was made to solve the above-mentioned conventional problems, and even if splicing is performed during operation of the component mounting apparatus, the tape reel that is exchanged and used is properly recorded in the history of trouble occurrence, It is another object of the present invention to provide a mounted component management method capable of properly grasping the remaining amount of components in a feeder in which the tape reel is stored.

The present invention relates to a manufacturing object in which a tape on which a part is affixed at a fixed pitch and wound on a tape reel is fed out by a feeder in which the tape reel is stored, the part is supplied, and the part is sucked. During the operation of the component mounting apparatus that is mounted at the corresponding position on the substrate, the new tape reel is spliced to the tail end of the tape reel tape being supplied with the new tape reel. When the parts supply from the reel is continued, the number of parts to be attached to the tape length within the range where the tape being supplied is short due to the structure of the feeder and cannot be spliced is minimized based on the fixed pitch. Calculate as the number of parts, and when splicing, the length of the tape that is still being supplied, the maximum possible number of parts to be attached to the tape length, Serial calculated as the maximum number of components on the basis of a predetermined pitch, after the splicing completed, until said minimum number of components parts, the part to determine as component supplied from the tape reel in the feed, of the component supply the tape reel reel・ Record the serial number as the usage history of the mounted parts, and after supplying the parts with the minimum number of parts, the parts with the maximum number of parts are identified as the parts supplied from the tape reel being supplied or the new tape reel. The reel serial number of the tape reel being supplied and the new tape reel is recorded as the usage history of the mounted component, and after supplying the maximum number of components, it is determined as the component supplied from the new tape reel. by the reel serial number該新tape reel was recorded as usage history of the mounting part, before Problems to solve, be performed spliced during operation of the component mounting apparatus, the tape reel used is exchanged, in which to properly record the record to be used when trouble occurs to be able to perform parts management .

Alternatively, the tape wound around the tape reel with the parts attached at a constant pitch is sent out by a feeder in which the tape reel is stored, the parts are supplied, the parts are sucked, and the substrate to be manufactured During the operation of the component mounting device that is mounted on the corresponding position above, by splicing the tip of the tape of the new tape reel to the tail of the tape reel that is supplying the component, the new tape reel When the parts are continuously supplied, the number of parts to be affixed to the tape length within a range where the tape being supplied is short due to the structure of the feeder and cannot be spliced is determined based on the fixed pitch. Calculate the number of parts to be applied to the tape length as the maximum possible length of the remaining part supply tape length when splicing. Calculated as the maximum number of components on the basis of a constant pitch, is recorded immediately before the splicing completed, the old parts remaining number is the number of remaining feeders in part, in the case of less than the minimum number component, the component If the remaining number of records is rewritten to (minimum number of components + (number of components on the new tape reel)), and the old number of remaining components is greater than or equal to the minimum number of components and smaller than the maximum number of components, The record of the number of remaining parts is rewritten to (the number of remaining old parts + the number of new tape reel parts). If the number of remaining old parts is equal to or greater than the maximum number of parts, the number of remaining parts is recorded as ( by was rewritten in said maximum number of parts + the number of new tape reel parts), to solve the above problems, even if the splicing during the operation of the component mounting apparatus, a feeder tape reel used is replaced is stored In To properly understand the parts remaining are those which make it possible to perform parts management.

  The operation of the present invention will be briefly described below.

  The part where the tape is covered with the cover near the position where the component is sucked by the mounting head in the feeder. For example, there is a range in which splicing cannot be performed due to a short tape during component supply. For this reason, in this invention, the number of components stuck on the tape length of this range is calculated as the minimum number of components based on the said fixed pitch.

  In addition, there is a maximum possible length of the remaining tape that is being supplied when splicing. For example, if the remaining tape is too long, splicing becomes difficult. For example, to splicing, loosen the old tape wound on the old reel and take out the tail end, or after splicing, wind the connected old tape on the new reel and store the new reel in the feeder, etc. If the old tape remaining when splicing is too long, it becomes difficult. Therefore, the number of parts to be pasted to the tape length of the maximum length is calculated as the maximum number of parts based on the constant pitch.

Thus, the tape reel components stored in the feeder can be managed based on the minimum number of components and the maximum number of components. For example, by the management, the grasp of the position of the tape connecting portion is properly made, part adsorbed to the mounting heads in the component mounting apparatus, or that of the old reel, or appropriately determine that the new reel is spliced In addition, the remaining number of parts in the feeder at the time of splicing can be appropriately updated.

  As described above, according to the present invention, even if splicing is performed during operation of the component mounting apparatus, the history of the tape reel that is replaced and used when the trouble occurs is properly recorded, and the tape reel is stored. It is possible to provide a mounted component management method capable of appropriately grasping the remaining amount of components in the feeder.

  The component mounting apparatus 20 according to the present embodiment can be connected to the network 24 by the LAN-I / F 313 of the control apparatus. It is possible to connect to the server device 22 via the network 24 and deliver necessary information.

  FIG. 5 is a top view of the tape 3 centering on the tape connecting portion in the present embodiment. 6 is a back view of the tape 3, FIG. 7 is a side view, and FIG. 8 is a cross-sectional view.

  In these drawings, reference numeral P0 denotes a splicing tape connecting portion. FIG. 5 shows the surface of the tape 3 as seen from above in FIG. On the other hand, FIG. 6 shows the reverse side as viewed from below in FIG. FIG. 7 is a side view seen from below in FIG. 8 is a cross-sectional view taken along the alternate long and short dash line P0 in FIG. 5. In FIG. 5, the upper side is the right side in FIG. 8, and the lower side in FIG.

  In these drawings, reference numeral 31 is a sprocket hole, and reference numeral 32 is a component, both of which are at a constant pitch on the tape 3. However, this is not specifically limited. 7 and 8, the component 32 is shown by a grid pattern of a right-up diagonal line and a left-up diagonal line. Reference numeral 34 denotes a carrier tape to which components are attached or embedded. Reference numeral 35 denotes a cover tape that covers such attachment and embedding.

  In these figures, the diagonally upward slanted areas denoted by reference numerals 41 to 43 are connection tapes for splicing, and all of them connect the old tape 3old and the new tape 3new across the tape connection portion P0. The connecting tape 41 is stuck on the carrier tape on the upper surface of the tape 3. The connecting tape 42 is attached to the back surface of the tape 3. The connecting tape 43 is attached to one side of the tape 3 on the side where the sprocket holes 31 are provided, straddling the front and back surfaces.

  Note that it is not always necessary to use all of these connection tapes 41 to 43, and any necessary tapes may be used as necessary. For example, only the connection tape 41 on the upper surface of the tape 3 and the connection tape 42 on the side surface of the tape 3 may be used.

  In FIG. 7, at the part 32, the connecting tape 43, the part 32, the carrier tape 34, the cover tape 35, and the connecting tape 41 are arranged in order from the bottom in the figure. In FIG. 8, the connecting tape 43, the component 32, the carrier tape 34, the cover tape 35, and the connecting tape 41 are sequentially formed from the connecting tape 43 below the component 32.

  FIG. 9 is a schematic diagram showing the minimum length and maximum length at the time of splicing, and the minimum number of components and the maximum number of components in the present embodiment.

  In FIG. 9, the bold line shown horizontally is the tape 3, the right side of the tape connecting portion P0 is the old tape 3old, and the left side is the new tape 3new. The component suction position 18 is denoted by reference numeral P1. The length from the reference symbol P1 to the reference symbol P0 is the old tape actual remaining length Lr, and the number of components pasted at a constant pitch in this length Lr is the minimum component number Nr. These old tape actual remaining length Lr and old tape actual component remaining number Nr may be strictly detected and grasped, but it requires expensive detecting means. Not.

  9 and also in FIG. 2 described above, the tape reel 5 is on the left side, and the component suction position 18 (P1) is on the right side.

  As described above, in order to update the number of remaining parts of the feeder or change the reel serving as the supply source history of the parts mounted on the board in accordance with splicing, the position of the tape connecting portion P0 is grasped. There is a need. In the present embodiment, the present invention is applied to grasp this.

  In FIG. 2, the guide part 14b is normally covered with a cover. Therefore, if it is not on the left side of the position 14d in FIG. 2, it is difficult or impossible to connect the new tape 3new to the old tape 3old and perform splicing. In this way, in the feeder structure, the range in which the tape being supplied is short and the splicing is difficult or impossible is the non-splicing range from the position P2 to the position P1 in FIG. Immediately after the splicing, the tape connecting portion P0 inevitably exists on the left side in FIG. 9, that is, on the tape reel 5 side from the splicing impossible range.

In the present embodiment, the length of the tape 3 (old tape 3 old) from the position P2 to the position P1 is set as the splicing minimum length Lmin. And the number of parts affixed on this tape 3 of the minimum length Lmin with a fixed pitch is set to the minimum number of parts Nmin. For example, it is assumed that parts are attached to the tape 3 at a pitch of M per unit length. In this case, the minimum number of parts Nmin can be calculated based on the following equation.
(Minimum number of parts Nmin) = (Minimum length Lmin) × M (1)

  Next, when splicing, the maximum possible length can be considered as the length of the tape in the remaining parts supply. That is, in most cases, immediately after the splicing, the tape connection portion P0 exists between the above-described position P2 and a specific position P3.

  In splicing, the old tape reel 5old, which is currently supplying parts, is left in the feeder while the parts can be supplied, and the old tape reel 5old is removed from the feeder, and the old tape reel 3old being wound is removed. Loosen and take out the end of the tape. For example, if the old tape 3old remaining on the old tape reel 5old is long, it cannot be loosened in this way.

Here, the splicing maximum length Lmax is set from the component suction position P1 to the specific position P3 that is the limit where the tape connecting portion P0 can exist. Further, the number of parts attached to the tape 3 having the maximum length Lmax at a constant pitch is defined as the maximum number of parts Nmax. For example, it is assumed that parts are attached to the tape 3 at a pitch of M per unit length. In this case, the maximum number of parts Nmax can be calculated based on the following equation.
(Maximum number of parts Nmax) = (Maximum length Lmax) × M (2)

  FIG. 10 is a flowchart showing reel / serial number recording processing in the present embodiment.

  In this embodiment, at least “board serial number data”, “part type data”, “reel serial number / first data”, “reel serial number / second data”, and “mounting position data” are provided. The component mounting record is recorded and saved in a predetermined information file provided in the storage area of the HDD device 340 for each component mounting on the board 19. The past information file is sent to the server device 22 via the network 24 and stored in the server device 22.

  Such a component mounting record can be used for investigating the cause or coping with a problem when a problem occurs in the board on which the component is mounted in the present embodiment. For example, it is assumed that a defect is found in a part of a specific lot, and the reel serial number of the tape reel 5 of the part included in the lot is clarified. In this case, the reel / serial number in question is extracted by extracting the component mounting record recorded in “reel / serial number / first data” or “reel / serial number / second data”. From the “substrate serial number data”, it is possible to select a substrate 19 that is defective or possibly defective.

  In the present embodiment, the mounting head 11 is provided with four nozzles 1 and can simultaneously suck four components. In addition, one cycle is that these components are sucked from the corresponding feeder 14 and then mounted on the substrate 19. Therefore, strictly speaking, after adsorbing a maximum of four parts and mounting these parts on the board 19, all the record records for each of the above-mentioned parts are newly recorded as a new record in the last part of the cycle. Like to do.

  The reel / serial number recording process shown in FIG. 10 is performed when such a new record is recorded for each component.

  First, in step S111, it is determined whether or not the tape 3 is spliced in the feeder 14 of the corresponding part. If it is determined that splicing has been performed, the process proceeds to step S121. If it is determined not to be spliced, the process proceeds to step S112.

  In step S112, it is determined whether or not the number Na of parts sucked by the feeder 14 after splicing is smaller than the minimum number of parts Nmin. If it is determined that the number is small, the process proceeds to step S121. If it is determined that the number is not small, the process proceeds to step S113.

  In step S113, it is determined whether or not the number of parts Na is smaller than the maximum number of parts Nmax. If it is determined that the number is small, the process proceeds to step S122. If it is determined that the number is not small, the process proceeds to step S123.

  In step S121, the reel serial number of the old tape reel 5old, or the current reel reel serial number of the tape reel 5 if not spliced, is recorded in the "reel serial number first data" of the new record. .

  In step S122, the reel serial number of the old tape reel 5old is recorded in the "reel serial number first data", and the reel serial number of the new tape reel 5new is recorded in the new record "reel serial number 2 data ".

  In step S123, the reel serial number of the new tape reel 5new is recorded in "reel serial number first data" of the new record.

  In any of these steps S121 to S123, other data of the new record is recorded thereafter. For example, in the new record, the serial number data of the board 19 on which the part is to be mounted is set as the above-mentioned “board serial number data”, and the data indicating the type of the mounted part is set as “part type data”. The data indicating the position where the component is mounted on the board 19 is recorded in the “mounting position data”.

  FIG. 11 is a flowchart showing the remaining component number update process in the present embodiment.

  When the operator inputs with the handy input device 350 that the splicing work including the connecting work using the connecting tape as described above is completed, the new tape reel is spliced and stored in the feeder 14 including the reel serial number. The information written in the 5new IC tag is read without contact. Alternatively, if the new tape reel 5new has no IC tag, necessary information including the reel serial number is input by reading a bar code or QR code or manually by an operator using the handy input device 350.

  The remaining part number update process of FIG. 11 is performed when such splicing is completed.

  The number of remaining parts of the feeder 14 immediately before the completion input of the splicing work is defined as the old number of remaining parts Nold. Further, the remaining number of parts updated in accordance with the completion input is set as a new remaining part number Nnew, and this is used as the remaining part number thereafter.

  In step S151, it is determined whether the old component remaining number Nold is smaller than the minimum component number Nmin. If it is determined that the number is small, the process proceeds to step S161. If it is determined that the number is not small, the process proceeds to step S152.

  In step S152, it is determined whether the old component remaining number Nold is smaller than the maximum component number Nmax. If it is determined that the number is small, the process proceeds to step S162. If it is determined that the number is not small, the process proceeds to step S163.

  In step S161, the old part remaining number Nold is updated to (minimum part number Nmin + new reel part number Np), and this is set as the new part remaining number Nnew. In step S162, the old part remaining number Nold is updated to (old part remaining number Nold + new reel part number Np), and this is set as the new part remaining number Nnew. In step S163, the old part remaining number Nold is updated to (maximum part number Nmax + new reel part number Np), and this is set as the new part remaining number Nnew.

  The above-described new reel component number Np is the total number of components that the new reel has.

In the present embodiment, the new component remaining number Nnew updated in this way falls within the following range.
(Minimum number of parts Nmin + Number of new reel parts Np) ≤ (Number of remaining new parts Nnew) ≤ (Maximum number of parts Nmax + Number of new reel parts Np) (3)

  In other words, in this embodiment, no matter how many times splicing is repeated, errors do not continue to accumulate in the new component remaining number Nnew, and the new component remaining number Nnew is always within the range of the above equation (3). Become.

  In addition, due to the structure of the feeder 14, the minimum length Lmin at the time of splicing is inevitably determined, and accordingly, the minimum number of parts Nmin is also determined. On the other hand, the splicing maximum length Lmax is largely dependent on the operator's operation status, and accordingly, the maximum number of parts Nmax is also largely dependent on the operator's operation status.

  Here, the operating condition of the operator is improved, and the maximum length Lmax is suppressed to be small, and the maximum number of parts Nmax is suppressed. Then, from the above (3), it is clear that the variation range of the old part remaining number Nold immediately before the completion input can be narrowed.

  In the component mounting apparatus 20 of the present embodiment, the statistics of the numerical value of the old component remaining number Nold may be automatically taken. For example, each time splicing, the old part remaining number Nold is stored, and this is stored as a history for an appropriate period, and an average value and standard deviation value of the old part remaining number Nold is obtained, and a handy input device In 350, these average values and standard deviation values may be displayed to the operator according to the operation of the operator. The operator may determine values of the maximum length Lmax and the maximum number of parts Nmax at the time of splicing with reference to the display and input from the handy input device 350. Further, in the component mounting apparatus 20 of the present embodiment, as an automatic learning function, the values of the maximum length Lmax and the maximum number of components Nmax during splicing are automatically updated based on these average values and standard deviation values. You may do it.

  As described above, according to the present embodiment, the present invention can be applied effectively.

  As described above, according to the present invention, even when splicing is performed during the operation of the component mounting apparatus, the history of the tape reel that is exchanged and used when the trouble occurs is properly recorded, and the tape reel is stored. It is possible to provide a mounted component management method capable of properly grasping the remaining amount of components in the feeder to be used.
