- the clearance and straightness between the upper and lower cuts are properly maintained.
- a third embodiment of the present invention will be described with reference again to FIG. 3 .
- the upper and lower movement of the holder part 10 is slidably supported by the module frame 110 .
- a well-known LM guide can also be considered for this sliding support.
- the cross roller guide 40 is provided in order to smoothly guide the sliding movement of the upper coat holder part 10 .
- the cross roller guide 40 is a guide having two guide rails having a V-shaped roller receiving groove and a plurality of rollers formed in a cylindrical shape. A plurality of rollers adjacent to each other may have orthogonal rotation axes.
- the two guide rails may be in surface contact with the rolling surfaces of the plurality of rollers. Since the detailed configuration of the cross-roller guide itself is known, further description is omitted.
- the first guide rail 41 of the cross roller guide 40 is installed in the module frame (side frame 112) of the cartridge module 100, and the second guide rail (42) was installed on the top coat holder part 10 side.
- the second guide rail 42 may slide and guide the first guide rail 41 while gently contacting it.
- two pairs of cross roller guides 40 are provided between the top holder 10 and the module frame 110 . In Figure 3 these two pairs of guides are well shown in the form of a perspective view with the device partially cut away.
- the first guide rail 41 of the cross roller guides 40 of each pair is installed outside the module frame (side frame 112) in the width direction, and the second guide rail 42 of each pair of guides ) is installed inside the module frame in the width direction.
- FIG. 9 is a perspective view showing a fourth embodiment of the present invention.
- the fourth embodiment employs the guide master 50 capable of preventing rotation in the circumferential direction of the guide shaft at the time of guiding.
- the guide master is composed of a needle roller, a retainer for holding the needle roller, a sleeve incorporating the retainer, and a post sliding into the sleeve. Since the guide master is provided with a needle roller and a polygonal retainer, there is an advantage that rotation of the post in the circumferential direction is prevented even when the post moves in the sleeve.
- the sleeve 51 is connected to the module frame 110, and the top holder part 10 is coupled to a post (not shown) installed in the post interior part 52 to slide up and down. .
- Fig. 10 is a schematic diagram showing a different form of a top coat as another embodiment of the present invention.
- the top view 10 of the form shown in Fig. 10 (a) is used.
- the width of both sides of the blade part at the bottom of the upper blade is large and the width of the blade is narrowing toward the center in the longitudinal direction. That is, the blade portion of the lower edge of the top is formed as a tapered portion 1a inclined upward toward the center in the longitudinal direction of the top.
- the reason for this configuration is to increase the shear angle of the portion (both sides) that first comes into contact with the electrode when cutting the electrode. If the shear angle is increased, the pressure can be easily distributed to both sides of the blade, thereby preventing the electrode from being torn or damaged.
- the depth of the central portion of the top coat is deep, so that the top coat 1 has to be pressed more deeply in order to completely cut the electrode. That is, there is a problem in that the stroke of the upper coat holder portion 10 is increased.
- the present inventor has proposed a multi-section top view (1) of FIG. 10(b).
- the taper part is formed of multi-stage taper parts having different inclination angles.
- the angle of inclination of the multi-stage tapered portions was configured to decrease toward the longitudinal center of the top.
- the upper blade 1 is formed as a tapered portion in which the lower blade portion is inclined upward toward the center of the upper blade longitudinal direction, and the tapered portion is the first tapered portion 1b of the upper portion side.
- the electrode can be efficiently cut without deeply pressing the upper blade by reducing the depth of the lower blade portion of the upper blade while increasing the shear angle with the first tapered portion 1b. That is, according to the present embodiment, there is an advantage in that it is possible to prevent an increase in the stroke of the top coat holder portion 10 and to prevent damage to the electrode during electrode cutting.
- the multi-stage taper part is configured in two steps toward the longitudinal center of the top coat, but it is also possible to configure three or more steps if necessary.
- a stripper 115 for separating the electrode from the top coating may be installed on the electrode inflow path between the top coating and the bottom coating. 7 and 8, when the stripper 115 is installed between the upper and lower coats on the electrode inflow path, the upper coat 1 descends and cuts the electrode, and then the electrode is stabbed in the upper coat 1 and attached to the top. Climbing is prevented by the stripper 115 .
- the stripper 115 is coupled to the module frame 110 and installed.
- the upper surface block 11 may be coupled to the front surface of the upper surface holder unit 10 .
- the top coating cover part 12 may be installed on the upper end of the top coating holder part 10 (refer to FIG. 8 above).
- the top coat block 11 and the top coat cover 12 are members that protect the top coat 1 and the top coat holder 10 and prevent contamination.
- the top coating front block 11 or the top coating cover part 12 may be removed.
