Description

  The present invention relates to a jig used when attaching an electrode plate for electrically connecting a battery and a circuit board or the like to a movement or the like in a movement or the like of a watch.

  In general, when attaching electrode plates to a ground plate including a lower plate, an upper plate, a mechanism receiving plate, a dust cover and the like of the movement, the electrode plates are attached to the ground plate one by one. The procedure is as follows. First, lightly insert the electrode plate into the slit of the main plate, and then press the electrode plate into the slit by pressing the electrode plate with a flat-tip tool such as a flat-blade screwdriver. Thereafter, the lead wire attaching portion for connecting the lead wire protruding to the lower side of the base plate is bent so as not to interfere with a dial plate attached to the base plate in a subsequent process. In such a procedure, the electrode plates were attached one by one.

  In the above prior art, the electrode plates are attached one by one, so at least two plates are attached to correspond to the positive and negative of the battery, and when using many batteries, a larger number of electrode plates are attached one by one. There was a problem that it was very time-consuming.

  Moreover, press-fitting and bending are necessary for attaching the electrode plate, and there is a problem that man-hours are required. Further, press-fitting and bending of the electrode plate require work from the front and back sides of the main plate, respectively, and workability is poor and it is difficult to improve work efficiency.

  The problem to be solved by the present invention is to provide a press-fitting jig for a timepiece electrode plate that solves the above-mentioned problems of the prior art, reduces man-hours, improves work efficiency, and further stabilizes quality. It is to provide.

  A press-fitting jig for a timepiece electrode plate according to the present invention includes a base for positioning and holding a base plate having a battery storage portion, a die plate set on the base and disposed below the battery storage portion, and the battery storage portion A punch for press-fitting the electrode plate set to the die plate, and a slope on which the lead wire mounting portion of the electrode plate protruding below the battery housing portion by press-fitting comes into contact with the die plate, The lead wire mounting portion is bent along the slope by press-fitting an electrode plate.

  The punch in the timepiece electrode plate press-fitting jig simultaneously press-fits a plurality of electrode plates, and the slope of the die plate simultaneously bends the lead wire mounting portions of the press-fitted electrode plates. The slope of the die plate has an inclination angle and an inclination direction so that a lead wire attachment portion of the electrode plate is bent so as not to interfere with a dial attached to the lower side of the base plate. Yes. The die plate is detachably attached to the table.

  According to the present invention, the electrode plate set on the ground plate can be pressed into the ground plate simply by pressing with a punch and can be bent at the slope of the die plate. Thereby, an electrode plate can be attached in 1 process and a man-hour can be reduced. In particular, when the electrode plate is bent, it is not necessary to work by inverting the ground plate, and the working efficiency can be greatly improved.

  In addition to pressing multiple plates at the same time with a punch, the lead wire mountings of multiple plates can be bent at the same time on the slope of the die plate, greatly reducing the time required to mount multiple plates. Since the height control after press-fitting of the electrode plate can be performed at once, work quality can be ensured.

  In addition, since the electrode plate is bent along the slope of the die plate, the electrode plate can always be bent in a stable shape, and various electrode plates can be obtained simply by changing the direction and angle of inclination of the die plate. It can be bent according to the distance between the main plate and the dial. In particular, since the die plate is detachably attached to the base, if a die plate with a different slope is prepared, it can be made compatible with various ground plates and electrode plates by simply replacing the die plate.

  The press-fitting jig for a timepiece electrode plate of the present invention is set on a base for holding a base plate having a battery storage section, a die plate set on the base and disposed below the battery storage section, and a battery storage section. And a punch for press-fitting the electrode plate. The die plate has a slope, and the lead wire mounting portion of the electrode plate that protrudes below the battery housing portion abuts on this slope. When the electrode plate is pressed with a punch, the lead wire mounting portion protrudes below the battery housing portion and bends along the slope of the die plate. As described above, when the press-fitting jig is used, press-fitting and bending of the electrode plate can be performed in one step.
