As such a device for measuring multiple ion activities, the present inventor proposed an instrument having the structure shown in FIG. 13 in % Application No. 148564/1983. This ion activity measuring instrument has an upper frame 1 and a lower frame 2.

It consists of a double-sided adhesive tape 5 that bonds the upper frame 1 and the lower frame 2 by sandwiching the sheet-like electrode 3 and the distribution member 4. The upper frame 1 has a bridge groove 7 formed with a bridge 6 on its outer surface, and a spotting hole 8 into which a liquid sample and a reference liquid are dropped. Further, a groove 9 for accommodating the entire electrode is formed on the inner surface of the upper frame 1, and when the sheet-like electrode 3 is fitted into this groove 9, the lower frame 2 has a groove 10 formed on the inner surface for accommodating the distribution member. is formed, and terminal holes 11 for electrical connection to electrodes are formed on both sides thereof, and the liquid distribution member 4 is accommodated in the groove 10 for accommodating the distribution member. The double-sided adhesive chip f5 has a dotting hole 12 and a liquid supply hole 13.

The first medium material number 82 is a winding roll, and this winding roll 82
is for winding up the remaining double-sided adhesive tape 5 after the first part of the frame body 2 has been processed.

Next, the operation of processing the lower frame body using the processing apparatus as described above will be explained.

First, the double-sided adhesive tape 5 is passed from the supply roll 21 to the take-up roll 82. At this time, no incision 26 is formed in the double-sided adhesive tape 5. While operating the air feeder 24 and intermittently transporting the double-sided adhesive tape 5 by a predetermined length, each time the movement is stopped, the perforation/cutting means 25 is inserted into the hole.
The punch 34 and the knife 35 are lowered, and the punch 34 makes holes in the upper release paper 22m, the double-sided adhesive tape 5, and the lower release paper 22b, and the knife 35 makes cuts 26 in the longitudinal direction near both ends of the upper release paper 22m. After forming, the state shown in FIG. 3 is obtained. Further, the double-sided adhesive chip f5 is adjusted to a predetermined position by a positioning roller 38 during transportation.

When the leading edge of the part where the cut 26 is formed by the knife 35 passes the positioning roller 38 and reaches the position of the peeling roll 41, only the part sandwiched by the cut 26 of the upper release paper is peeled off from the double-sided adhesive tape. Then, the release paper winding roll 401C is passed through the release roll 41. As the double-sided adhesive tape 5 is transferred, the center portion of the upper release paper 22m is wound up by the release paper take-up roll 40 via the release roll 41, resulting in the state shown in FIG.

Furthermore, when it is intermittently transferred and reaches the liquid distribution member bonding means 28, No. 4? The punch 47 descends and punches out the liquid distribution member 4 at the p4y hole 50, and the punch 47 further descends to reach the double-sided adhesive tape 5 and punch out the liquid distribution member 4 punched out.
is pressed and attached to the double-sided adhesive tape 5, resulting in the state shown in FIG. is supplied.

When the liquid distribution member is transferred from the liquid distribution member bonding means 28 to the lower frame bonding means 29, the air cylinder 56 shown in FIG. 11 is operated to advance the slider 57 onto the pace 52. At this time, the lower frame 2 which has been pulled out from the holder 53 and fitted into the recess 58 of the slider 57 moves onto the pace 52.

Next, after suctioning and fixing the lower frame body 2 with the suction port 61, the cylinder 56 is operated to move the slider 57f back to the lower end of the holder 53, and then the cylinder 59 is activated and the suction block 6
0 to press the lower frame 2 onto the screen adhesive tape 5. In this way, the lower frame body 2 is adhered to the predetermined portion of the double-sided adhesive tape 5 to which the liquid distribution member 4 is adhered, resulting in the state shown in FIG. 6.

After this, the sandwiching part 64 of the air feeder 24 is attached to the remaining upper and lower release paper 2 on both sides of the double-sided adhesive tape 5.
Hold 2a and 22b and use air cylinder/85 in this state.
is operated to transport the double-sided adhesive chip f5 a predetermined length. Next, after the release paper 22 is released from the holding portion 64, the operation of the air cylinder 85 is also released to return to the original state. In this way, after the work such as cutting is completed, the release paper 22 is again held by the holding portion 64 and transported a predetermined length.

When the tape in the state shown in FIG. 6 is transferred to the lower release paper cutting means 30, the cylinder 68 is actuated to raise the lower die 67 and lower it while pressing the double-sided adhesive chip f5 toward the upper die 66. A cut 31 is formed in the side release paper 22b and the double-sided adhesive chip f5, resulting in the state shown in FIG. 7. Then, in the separating means 32, the cylinder 78 is operated to remove the suction port 8.
After the lower frame 2 is suctioned from 0 and peeled off from the double-sided adhesive tape 5, the suction port 80 is positioned above the discharge magazine 71 from the cylinder 74. Here, when the cylinder 78 is deactivated and the N suction is released, the lower frame 2 to which the double-sided adhesive tape 5 and the lower release paper 22b are integrally adhered falls and is housed in the discharge magazine 71. The lower frame 2 housed in the discharge magazine 71 is combined with the upper frame and sent to the next step to produce a finished product of the ion activity measuring instrument.

Further, the remaining double-sided adhesive chip f5 is wound onto a winding roll 82.

In the next step, the lower release paper attached via the lower frame body pressure double-sided adhesive tape is peeled off to expose the adhesive surface of the double-sided adhesive tape, and other components to be assembled, such as an ion activity measurement device, are removed. The two members can be fixed to each other via double-sided adhesive tape by attaching the upper frame bodies of the two members in a predetermined positional relationship.

〔Effect of the invention〕

The present invention is constructed as described above, and since the release paper on at least one side of the double-sided adhesive tape remains until the end, the double-sided adhesive tape can be transferred via the remaining release paper, and the double-sided adhesive tape It is possible to efficiently and accurately adhere components to one side of the substrate sequentially and continuously.

Furthermore, after pasting a member, such as the lower frame of a liquid analysis instrument, on one double-sided adhesive tape, a cut is made in the double-sided adhesive tape and one side of the release paper slightly inside the outer periphery of the pasted surface, so that the said member The tape can be easily removed from the unnecessary portion of the double-sided adhesive tape along with the release paper on the opposite side. In addition, since the double-sided adhesive tape is cut inside the entire periphery of the surface to which it is attached to the component, the adhesive of the double-sided adhesive tape does not protrude beyond the surface to which it is attached, and is processed in subsequent steps. Work can be carried out efficiently without unnecessary adhesion with equipment or other parts. ,%, it is effective when used to produce the lower frame part or the upper frame part of an ion activity measuring instrument, and highly accurate frame parts can be mass-produced efficiently.
