Description

  The present invention relates to a joining apparatus and joining method for joining a base and a lid of an electronic component.

  In recent years, a joining apparatus and a joining method are joined by overlapping an electronic component base and a lid, bringing an electrode into contact with an object to be joined, and flowing an electric current.

  In order to increase production efficiency, there is a method of placing a plurality of objects to be bonded on the pallet in the X-axis and Y-axis directions as a method for setting the objects to be bonded in the conventional bonding apparatus and bonding method. Depending on the production status, the number of objects to be placed on the pallet is often not constant.

The premise is that a sensor is used as a method for detecting the presence / absence of an object mounted on a pallet, a method for inputting the presence / absence of an object to be bonded for each coordinate of the pallet, or that a full number is mounted on a pallet. There was also.
JP-A-9-19772 (page 3-0017, FIG. 2) Japanese Patent Laid-Open No. 9-150277 (page 3-0012, FIG. 3) Japanese Patent No. 3274221 (page 3-0016, FIG. 8) Japanese Patent No. 2824894 (page 2-0008, FIG. 4)

  However, with the conventional joining device and joining method, the sensor is erroneously detected due to the ambient temperature, humidity, etc., cloudiness of the lens part of the sensor, etc. there were. In addition, if the sensor detects falsely, it is judged that there is no object to be joined, and the unjoined object is taken out to the subsequent process, or conversely, there is no object to be joined. Incorrect detection may cause a junction current to flow and damage the electrode. In addition, the structure of the device is complicated for sensor detection, and the price of the device is also expensive. In this method, as the outer shape of the object to be joined becomes smaller and the thickness becomes thinner, detection by the sensor has a limit, and detection is impossible.

  On the other hand, the method of inputting the presence / absence of the object to be joined for each coordinate of the pallet takes time to input the presence / absence of the object to be joined to each coordinate when, for example, 200 pieces are placed on one pallet. There is a case where you enter it incorrectly. If the number of objects to be joined is assumed to be full, there is a problem that the joining operation of the objects to be joined by fractions cannot be produced.

  If different devices are used depending on the type of object to be joined and the joining method, the equipment cost increases and the installation space also increases.

In order to solve the above problems, the present invention inputs a pallet on which a plurality of workpieces are placed in order in at least the orthogonal X-axis direction or Y-axis direction, and the total number of workpieces to be placed on the pallet. An input unit, an electrode to be brought into contact with an object to be bonded, a Z-axis lifting unit for vertically moving the electrode, a driving unit for controlling the relative position of the electrode and the pallet, and an X-axis after the end of the bonding in the Y-axis direction A control unit that outputs a signal for moving the electrode and the pallet to the driving unit at a movement switching point in a direction, a power supply unit that supplies power to the electrode, and a bonding unit that selects a bonding direction for each number of columns of the X axis. A direction selection unit and an operation control unit according to the number of placements for comparing the total number of placements of the objects to be joined to the product of the maximum number of placements of each of the objects to be joined on the X axis and the Y axis set in advance.

  Further, an electrode lifting / lowering operation presence / absence selection unit, a bonding direction selection unit, at least one input unit for inputting the number of arbitrary objects to be bonded, a post-stop operation selection unit, a correction value input unit, A joining length input unit for the object to be joined, a start point travel delay input unit, and an end point junction stop delay input unit are provided.

  With this configuration, the joining direction is selected for each number of rows on the X axis, and the full joining order operation or the fraction joining order operation is performed according to the total number of objects to be joined.

  As described above, the present invention switches the Y-axis bonding direction of the objects to be bonded alternately between the objects to be bonded each time the number of X-axis rows increases by +1. It is possible to move to the shortest distance to. As a result, since the objects to be joined can be joined in a short time, workability can be improved and efficiency can be increased.

  On the other hand, when all the X-axis rows are joined in the same direction, depending on the relative positional relationship between the electrode and the pallet, the pulling force while the electrode is in contact with the object to be joined stabilizes the strength, uniformity, sealing degree. For example, a more effective joining result may be obtained.

  Further, by inputting only the total number of the plurality of objects to be joined placed on the pallet, the full joining order operation and the fraction joining order operation can be easily performed. For example, when 200 full workpieces can be placed on one pallet, enter 200 when the total number of workpieces is 200 and 36 when the total number is 36. input. The full or fractional number is automatically determined according to the total number of mounted parts, and the full joining order operation or the fraction joining order operation is performed accordingly. When switching production lots, a small amount of workpieces are often placed rather than placing a full pallet of 200 pallets, and when a new workpiece is produced, joining In many cases, a small amount of an object to be joined is placed in order to determine the conditions. In this way, the fraction joining sequence operation automatically calculates whether or not there is a fractional line depending on the total number of placements and whether the fractional line is an even number or odd number. Can join objects. Even if there are a plurality of pallets and a different total number of placements is input to each of them, the fraction joining sequence operation can be performed. For example, 157 pallets, 94 pallets 2 and 198 pallets 3 can be joined together.

  Since the electrode can be lifted when the pallet is moved in the Y-axis direction while the electrode is not in contact with the pallet in the non-bonding section between the plurality of objects mounted in the Y-axis direction, Tacking can be performed.

  When an emergency stop occurs in the middle of joining operations of multiple workpieces, select whether to continue the joining operation from the next workpiece after the stopped workpiece or to forcibly terminate the pallet joining operation. Therefore, it is possible to decide whether to continue or finish depending on the joining result up to the middle.

When the accuracy differs somewhat depending on the type of pallet, by inputting the respective axis correction values of the X-axis and Y-axis direction joining start position of the workpiece to be the reference position of the first first workpiece to be joined, The reference position can be corrected.

  Depending on the type of the objects to be joined, it may be better for the joining result that the joining length starts and ends slightly. In such a case, the entire joining length is changed by inputting respective values to the joining length input portion of the object to be joined and the start length plus α1 input portion and the end length plus α2 input portion with respect to the joining length. be able to.

  Also, a start point travel delay input unit where the pallet starts traveling in the Y-axis direction after a certain time from the joining start position of the workpieces, and an end point joint where the pallet stops traveling in the Y-axis direction after the pallet stops traveling in the Y-axis direction. With the stop delay input section, particularly important start and end joining conditions can be adjusted.

  Since the present invention does not use a sensor for detecting an object to be bonded, the sensor does not erroneously detect due to ambient temperature, humidity, etc., clouding of the sensor lens part, etc. Regardless, it is determined that there is no connection, and unbonded objects are carried out to the subsequent process, or conversely, there is no object to be bonded, and it is erroneously detected that there is no object to be bonded, so that no bonding current flows. It doesn't hurt.

  Alternatively, since the detection sensor cable of the object to be joined is not used, the cable is not disconnected, so that it is not necessary to perform daily management, and the maintenance is excellent. In addition, since the sensor, parts for attaching the sensor, and cables are not used, the structure of the apparatus becomes simple and the price of the apparatus becomes economical. In the method of using the sensor for detecting the object to be bonded, the detection by the sensor has a limit as the outer shape of the object to be bonded becomes smaller and the thickness becomes thinner. It is.

  During automatic joining operation of workpieces mounted on a pallet, the number of workpieces to be mounted that is the same as or different from the number of workpieces mounted on that pallet is reserved and input to the pallet for the next operation. Any number of the workpieces to be joined can be continuously joined.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

(Embodiment 1)
The electrodes 4 to be brought into contact with the objects to be joined 1a, 1b, 1c placed on the pallets 2a, 2b, 2c in FIG. 1 are connected to a power supply unit 10 for supplying power by a joining cable 21, and Can be raised and lowered vertically.

  The control unit 9 controls the relative position of the electrode 4 and the objects to be bonded 1a, 1b, 1c or the pallets 2a, 2b, 2c by the driving unit, and the Y-axis direction in which the objects to be bonded 1a, 1b, 1c are placed in order. A signal for moving the electrode 4 and the objects to be joined 1a, 1b, 1c at the switching point of the reciprocating motion in the X-axis direction orthogonal to is output to the drive unit 8.

  The number-by-placement operation control unit 11 includes the predetermined X-axis workpiece maximum placement setting number Nx-max in the column direction and the Y-axis workpiece maximum placement setting number Ny-max in the row direction in FIG. When the product and the total number of the objects to be joined are equal, the operation to fill the object to be joined is performed. When the total number of the objects to be joined is less than the product, the fractional object operation is controlled.

On the surface of the pallet 2a in FIG. 3 (a), 200 concave pockets P1 to P200 that are filled by placing 200 pieces are formed, and the pallet 2a is sequentially arranged in the X-axis and Y-axis directions. A plurality of objects 1a such as a base and a lid are placed in 200 concave pockets P1 to P200, and pallets 2a, 2b, and 2c are mounted on the tray 3 in FIG.

  The tray 3 has positioning pins (not shown), and the pallets 2a, 2b, 2c are positioned on the tray 3, respectively. The numbering of the pockets from P1 to P200 starts at P1 and becomes p20 at the end of one line on the Y axis. Then, it is folded back to p21 in two rows from the X axis to the Y axis in 20 columns.

  FIG. 3 shows an example of 200 concave pockets, but a pallet with 30 rows for the X axis, 8 rows for the Y axis, 25 rows for the X axis, 10 rows for the Y axis, and the like is also possible.

  (A), (b), (c), and (d) of FIG. 4 show examples in which fractional objects 1a are placed on the pallet 2a of FIG. In the example of (a), since the workpiece 1a is placed in the pockets P1 to P23, the total placement number of the pallet 2a is input as "23" by the input unit 12 of FIG. Similarly, in the example of (b), since the workpiece 1a is placed in the pockets P1 to P24, the total placement number of the pallets 2a is input as "24" by the input unit 12 of FIG. In the example of (c), since the workpiece 1a is placed in the pockets P1 to P44, "44" is input as the total placement number of the pallet 2a by the input unit 12 of FIG. In the example of (d), since the workpiece 1a is placed in the pockets P1 to P43, the total placement number of the pallet 2a is input as "43" by the input unit 12 of FIG.

  (A) to (d) of FIG. 4 is an example of fraction placement in which 200 non-full articles to be joined 1a are placed on the pallet 2a. When the workpiece 1a is placed in the pockets P1 to P200 on the pallet 2a shown in FIG. 3, "200" is input as the total placement number of the pallet 2a by the input unit 12 shown in FIG.

  As the common data of the pallets 2a, 2b, and 2c in FIG. 3, "20" is input by the input unit 12 in FIG. 1 as the X-axis workpiece maximum placement setting number Nx-max in the column direction, and the Y axis in the row direction “10” is input by the input unit 12 of FIG. 1 as the maximum number Ny-max of the object to be bonded.

  The product of the X-axis workpiece maximum placement setting number Nx-max = 20 and the Y-axis workpiece maximum placement setting number Ny-max = 10, that is, 20 × 10 = 200 is the workpieces 1a, 1b, 1c. It becomes the total number of full loading. Also, the short side direction interval Xp, the long side direction interval Yp, the positioning reference position Cp that is the gauge center position of the tray 3, the X-axis bonding start position Xs of the first workpiece 1a to be bonded on the pallet 2a, and the Y-axis bonding start The pallet interval Pp where the position Ys and the pallets 2a, 2b, and 2c are arranged is input by the input unit 12 in advance. These values are used for movement calculation of the pallets 2a, 2b, 2c at the time of joining.

  3 indicates 200 concave pockets P1 to P200, and FIG. 4 indicates that the presence of the object 1a is omitted.

(Embodiment 2)
A specific operation in the case where “200” is input as the total placement number will be described with reference to the operation flowchart of FIG. 2 and FIG. 3. In S1 of FIG. 2 (S is an abbreviation of step), it is determined whether the joining direction is selected as “same / alternate”. If “alternate” is selected, the process proceeds to S2, and if “200” is input as the total number of placements in FIG. 3, the process proceeds to S3. If “same” is selected, the process proceeds to S13. The operation when “same” is selected will be described later. Here, S3 of the operation flowchart of FIG. 2 will be described.

In FIG. 3, it joins from p1 mounted in one column of the X axis and one row of the Y axis, and one column of the X axis remains as it is, and the electrode 4 in FIG. Move to 10 lines and join. When the joining of the X-axis 1 column and the Y-axis 10 rows to-be-joined objects 1a is completed, the electrode 4 rises and the electrode 4 moves in the X-axis direction 2 columns.

  Then, the electrode 4 descends at the position of the X-axis 1 column and the Y-axis 10 rows and joins from the p199 placed on the X-axis 2 columns and the Y-axis 10 rows, and the X-axis 2 columns remain as they are in FIG. The electrode 4 is moved down and joined from the 10th row of the Y-axis to the first row while being lowered. When the joining of the X-axis 2 columns and the Y-axis 1 row to-be-joined object 1a is completed, the electrode 4 rises and the electrode 4 moves in the X-axis direction 3 columns.

  When the process is repeated and the joining of the workpieces 1a in the X-axis 20 columns and the Y-axis one row is finished, the joining of all the workpieces 1a placed on the pallet 2a is finished. Next, the to-be-joined object 1b mounted on the pallet 2b is joined.

(Embodiment 3)
The process proceeds to S5 in the operation flowchart of FIG. 2, and the specific operation when the total number of placements is input as “40” in FIG. 3 will be described.

  If the total number of mounted objects 1a is “40”, the total number “40” of the objects to be bonded 1a is divided by the maximum setting number of X-axis objects to be bonded “20”. ÷ 20 = 2 Since the remainder is 0, the number “2” of the quotient is a full line, and the number “3” obtained by adding 1 to the full line is a fractional line on the Y axis.

  Since the remainder is 0 in the fractional line on the Y axis, the fraction becomes “None” and the process proceeds to S5. Then, only the first and second rows that are full in the Y-axis are joined by the Y-axis alternating direction joining as described in the second embodiment from the first column of the X-axis to the 20th column.

(Embodiment 4)
The process proceeds to S9 in the operation flowchart of FIG. 2, and the specific operation when the total number of placements is input as “23” in FIG. In FIG. 4A, since the total number of placements is input as “23”, it is less than 200, so it is determined as “fraction” and the process proceeds to S4.

  When the process proceeds to S4 in FIG. 2, it is determined whether the fractional line is “remaining” or “not much”. The total number “23” of the workpieces 1a is divided by “20” which is the maximum placement number of the X-axis workpieces, so that 23 ÷ 20 = 1 is a remainder of 3. Therefore, the quotient number “1” is A full line is set, and a number “2” obtained by adding 1 to the full line is a fractional line on the Y axis. Since the remainder is 3, the remainder becomes “Yes” and the process proceeds to S6.

  Since the fractional line is “2”, the fractional line becomes even and the process proceeds to S7. In order to determine in which column of the X axis the “23” workpieces 1a that are the first value in the fractional row are present, when the fractional row is an even number, the X-axis workpiece maximum placement setting number “20” is set. The X-axis column to be obtained is obtained by subtracting the remainder 3 from "and adding +1 to it." Expressed in the equation, (20-3) + 1 = 18. That is, the X-axis fraction column in the fraction row is in 18 columns, and the process proceeds to S9. When the fractional line is an odd number, the remainder becomes the number of X-axis columns that is the first value of the fractional line.

  In S9, the Y-axis direction is alternately joined, and the operation in the joining order is performed in which the fractional rows of the Y-axis are even and the X-axis column is even. The operation when the total number of placements is input as “23” in FIG. 4A will be described. The joining direction of the Y-axis is joined from the first row to the second row, and the Y-axis is joined in the X-axis one column.

When the joining of the X-axis 2 columns and the Y-axis 1 row to-be-joined object 1a is completed, the electrode 4 rises and the electrodes 4 move to three columns in the X-axis direction. The process is repeated in this way, and one row, which is a full Y-axis row, is sequentially joined from the first column of the X axis to the 17th column.

  When the joining of the workpieces 1a in the X axis 17 columns and the Y axis 1 row is completed in FIG. 4A, the electrode 4 in FIG. 1 rises and moves to the X axis 18 columns. Then, the pallet 2a moves to the X axis 18 columns and the Y axis 2 rows. Then, the electrode 4 is lowered to join p23 of the workpiece 1a placed on the X axis 18 column and the Y axis 2 rows, and the pallet 2a is lowered to the X axis 18 column, Y, while the electrode 4 is lowered. Move to one axis line. Next, the to-be-joined object 1a mounted there is joined. When the joining of p18 is completed, the electrode 4 in FIG. 1 rises and moves to the X axis 19 rows. Then, the electrode 4 is lowered to join p19 of the workpiece 1a placed in the X axis 19 column and the Y axis 1 row, and the pallet 2a is lowered to the X axis 19 column, Y while the electrode 4 is lowered. Move to axis 2 row. Then, the objects to be joined 1a placed on the X axis 19 columns and the Y axis 2 rows are joined. Thereafter, the same operation is performed.

  That is, (a) in FIG. 4 shows the case where the fractional row is an even number, and when the p23 bonded object 1a placed at the head of the fractional row is in the X-axis even number 18 column, After joining the workpieces 1a placed on the Y-axis full row of the 17th column of the X-axis with the subtracting, move to the workpiece 1a of p23 placed at the beginning of the fractional row.

Move to. Next, the objects 1a placed on the X axis 17 columns and the Y axis 2 rows are joined. When the bonding of p24 is completed, the electrode 4 in FIG. 1 moves up and moves to the X axis 18 row. Thereafter, after the electrode 4 moves to the X axis 18 rows, the same operation as that described in the second embodiment is performed.

It is assumed that the joining direction is selected as “alternate”, and the p43 to-be-joined 1a placed at the beginning of the fractional row is placed on the X-axis even three columns and the fractional rows are odd three rows. The process proceeds from S8 to S12 in FIG. The same operations as those described in the fourth embodiment are performed until the p43 to-be-joined objects 1a placed in the last three rows of the X-axis three columns of the Y-axis are joined.

  When the bonding of the object to be bonded 1a at p43 is completed, the electrode 4 rises and moves to the X axis 4 columns and the pallet 2a to the Y axis 2 rows. Next, bonding of the objects to be bonded 1a of p37 placed in the X-axis 4 columns and the Y-axis 2 rows is performed. When the bonding of p37 is completed, the electrode 4 is kept lowered, and the bonded object 1a of p4 placed on the X-axis 4 columns and the Y-axis 1 row is bonded. Thereafter, the joining of the X axis 5 to 20 columns and the Y axis 1 row to 2 rows performs the same operation as described in the second embodiment.

A specific operation when “23” is input as the total placement number will be described with reference to S17 of the operation flowchart of FIG. 2 and FIG. When the process proceeds to S15 in FIG. 2, it is determined whether the fractional line is “remainder present” or “remainder absent”. The total number “23” of the workpieces 1a is divided by “20” which is the maximum placement number of the X-axis workpieces, so that 23 ÷ 20 = 1 is a remainder of 3. Therefore, the quotient number “1” is A full line is set, and a number “2” obtained by adding 1 to the full line is a fractional line on the Y axis. Since the remainder is 3, the remainder becomes “Yes” and the process proceeds to S17, and since the fractional line is “2”, the fractional line becomes even and the process proceeds to S18.

  When the pallet 2a moves to the joining start position of the X axis 1 column and the Y axis 1 row with the electrode 4 raised, the electrode 4 descends, and the X axis 1 column extends from the Y axis 2 row side to the 1 row direction. Bonding to. When the joining of the X-axis 1 column and the Y-axis 1 row is completed, the electrode 4 rises and moves to the X-axis 2 rows. At the same time, the pallet 2a moves toward the Y-axis 2 rows and the electrode 4 descends.
