[0001]
[Industrial applications]
The present invention relates to an electronic component mounting apparatus for mounting an electronic component.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as shown in FIG. 6, an electronic component mounting apparatus (hereinafter, referred to as a mounting machine) has a component cassette 1 mounted on a component supply unit, a name of a component mounted on the component cassette 1, and a code number representing a specification of the component. , A memory 2 storing symbols, data reading / writing means 4 for transmitting / receiving information from / to this memory, and a program holding means for holding a program 12 for designating which part should be placed in which part of the parts supply unit. 6. A component supply information holding unit 8 for displaying the component supply cassette information 13 in the component supply unit when a component exhaustion occurs is provided. The operator supplies a new component cassette to the component supply unit in accordance with the information of the component supply information storage unit 8. set.
[0003]
When the supply of the component cassette is completed, the component replacement completion button 7 is pressed, and the completion of the component replacement is notified to the mounting machine.
Next, whether the component cassette mounted on the mounting machine is a correct component is checked by the component checking unit 10 before starting the mounting operation, and if there is a mismatch, the display and operation prohibition processing unit 9 Processing such as warning and not starting the mounting operation has been performed automatically. Such an operation is usually performed before starting a new production or when a part runs out during production and is replaced with another parts cassette containing parts.
[0004]
[Problems to be solved by the invention]
However, in the conventional mounting apparatus, if a component is run out and an operator erroneously replaces an adjacent component cassette, the component cannot be properly collated unless all component cassettes are collated. When collating all the component cassettes, the communication time between the memory mounted on each component cassette and the data reading / writing means for reading the information in the memory, the time for moving the component supply unit, and the In this case, it takes time to perform a check with a prepared program for mounting, and a lot of time is lost before the check of all parts is completed and the production is restarted. For example, if 300 parts cassettes are mounted, and it takes 2 seconds to verify the components of one cassette, a loss of 600 seconds, that is, 10 minutes occurs for the verification of 300 parts. There has been a problem that, if it occurs every time a part runs out, the operating rate of the apparatus is greatly reduced.
[0005]
The present invention is to solve the above-mentioned conventional problem, and to provide an apparatus that appropriately performs parts collation without lowering the operation rate of the apparatus even if an operator makes a mistake in replacing a parts cassette when parts are exhausted. is there.
[0006]
[Means for Solving the Problems]
In order to solve the above problem, an electronic component mounting apparatus of the present invention includes a storage unit that stores a component name of a component cassette mounted on a component supply unit, a component code, and the like, and a data read / write unit that reads or writes this information, A component supply information holding unit that holds and manages the number of a component supply unit in which a cassette to be replaced or replaced is mounted, an adjacent component matching information holding unit that manages the number of adjacent component matches, and an electronic component. A program holding means for holding a program for mounting, a component collating means for judging whether or not a mounted component is correct, and, when a correct component is not mounted, notifying the operator of the fact and not displaying a restart of the mounting operation. , And operation inhibiting means.
[0007]
Further, the data reading / writing means can read / write information of a plurality of component cassettes at a time.
[0008]
[Action]
According to the above configuration, when a component shortage occurs in the electronic component mounting process, the component supply information holding unit holds information on the component cassette in the mounting machine where the component shortage has occurred. On the other hand, the number of component cassettes to be subjected to component collation for an adjacent component cassette when a component cassette runs out of components is set in advance in the adjacent component collation information holding means.
[0009]
Further, in each of the component cassettes, a component name, a component code number indicating the specification of the component, and symbol information are stored in a storage unit. The component supply unit is moved to the position of the storage means in order to read out the information of the storage means, the information in the storage means is read out, and it is checked whether or not the correct part is mounted by comparing the information with the target mounting program. At this time, adjacent component cassettes are collated in advance according to the set component cassette collation number, and the same collating process is performed simultaneously on adjacent component cassettes.
[0010]
The display / operation prohibition processing unit for performing the display / operation prohibition process, when the component matching is found as a result of the collation process, displays the result on a display device, and the operator prohibits the restart of the production.
[0011]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Components having the same configuration as that shown in FIGS. 6 and 7 showing a conventional mounting process are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 1 is a block diagram showing a component cassette replacement process at the time of running out of components in an electronic component mounting process according to one embodiment of the present invention. In FIG. 1, each component cassette 1 is equipped with a storage means 2 which stores names of electronic components, component code numbers indicating the specifications of components, and symbols. As the storage means, for example, a memory backed up by a battery is used. The mounter 3 is provided with data read / write means 4 for reading or writing information in the memory, and exchanges data with the memory in a non-contact state. When the component supply unit is divided into two parts left and right, the data read / write unit 4 is fixed to the mounting machine one by one on the left and right sides. By moving the component supply unit 5, information on each component cassette 1 is read. Can be served. On the other hand, the program holding means 6, which holds the program 12 of the electronic component currently mounted, also holds information on which part of the component supply unit should be placed which component.
[0012]
When a component shortage occurs, the component supply information holding means 8 stores component shortage information as information as to which part of the component cassette in the component supply unit is out of component in the mounting machine as shown in the flowchart of FIG. 13 remain. The operator removes the component cassette and sets a new component cassette containing components in the component supply unit.
[0013]
When this operation is completed, the operator presses the component replacement completion button 7 to notify the completion of the component replacement to the mounting machine. Next, the part supply unit 5 is moved to the position of the storage means 2 and the parts are collated by collating with the mounting program in the storage means 2. The adjacent part collation information holding means 11 holds information on the number of parts to be collated for the part cassette adjacent to the replaced part cassette. It is assumed that when a certain component cassette has run out of components, it has been set so that two adjacent component cassettes on the left and right sides are collated. For example, as shown in FIG. 3, if the component with the Z number 25 has run out of components, the mounting machine checks a total of five component cassettes from the Z numbers 23 to 27. At this time, if the time required for component verification is 2 seconds per location, 2 seconds × 5 locations = 10 seconds.
[0014]
In the collation of the component cassette, the data read / write unit 4 is instructed by the component supply information holding unit 8, reads the memory mounted on the newly supplied component cassette, and compares this with the program held by the program holding unit 6. This is performed by checking whether or not the part name and the part code match with each other by the part and matching means 10. If the two information are inconsistent, the display / operation prohibition processing unit 9 displays "Make mistake in parts" on the display and performs processing such as not restarting production even if the start button is pressed.
[0015]
It is assumed that the operator can freely set the number of parts collation of the adjacent parts cassette. In the present embodiment, the component supply unit is divided into two parts on the left and right, and one data read / write unit is provided on each of the left and right sides. Now, it is assumed that three data read / write units are provided on each of the right and left sides, and the data read / write units are set so as to collate up to two adjacent component cassettes. For example, as shown in FIG. 4, if the component with the Z number 25 has run out of components, the mounting machine checks a total of five component cassettes from the Z numbers 23 to 27. Only two times are required to check the component cassettes 23 to 25 and to check the component cassettes with Z numbers 26 and 27. At this time, the time can be further reduced as compared with the case where the component supply unit is moved five times.
[0016]
【The invention's effect】
As described above, according to the present invention, when a component shortage occurs and a component cassette is replaced, the information in the storage unit is read out and compared with the target mounting program to determine whether the correct component is mounted. Is checked at the same time and the adjacent component cassettes are collated according to the preset number of component cassette collation, so that even if the operator mistakenly replaces a component cassette other than the target, all component cassettes are not collated. The parts can be efficiently collated.
