- the shim plate whose position is adjusted according to the present invention may be positioned so that the outer end position (S) of the lower die block and the shim plate end position (L M ) are on the same line as in (a), and in this case, the offset of the shim plate may be "0".
- the shim plate may be positioned so that the end of the shim plate is located (L M ) on the inside of the lower die block as in (b), so that the offset of the shim plate may have a negative (-) value with respect to the outer end (S) of the lower die block.
- the offset of the shim plate affects the loading amount, etc.
- each step of the position adjustment method of the present invention may satisfy predetermined conditions.
- the position adjustment method includes a step (S1) of attaching a position adjustment device to the front outer side of the lower die block on which the shim plate is arranged.
- This step (S1) refers to a process of attaching the position adjustment device to the front outer side of the lower die block on which the shim plate is placed to fix the device so that it does not shake.
- the "front outer side of the lower die block” refers to the outer side of the lower die block where a slot is provided by the shim plate.
- the position at which the position adjustment device is attached may be an area adjacent to the end of the shim plate arranged in the lower die block, for example, the front outer upper side of the lower die block where the end of the shim plate is located, in order to easily adjust the position of the shim plate.
- the displacement measuring device and the position controller of the position adjusting device attached in this step (S1) can be positioned so as to be spaced apart from the end of the shim plate by a predetermined distance (e.g., 0.1 mm to 100 mm, 0.1 mm to 50 mm, or 0.1 mm to 20 mm) in the longitudinal direction (x-axis direction) of the shim plate.
- a predetermined distance e.g., 0.1 mm to 100 mm, 0.1 mm to 50 mm, or 0.1 mm to 20 mm
- this step (S2) refers to a process of adjusting the positions of the displacement measuring device and the position controller of the position adjustment device using a moving mechanism included in the position adjustment device and fixing the adjusted positions.
- the present step (S2) may include a step (S2-1) of moving the position of the end of the displacement measuring device in at least one of the width direction and the height direction of the lower die block so that the end of the shim plate and the end of the displacement measuring device face each other; and a step (S2-2) of fixing the position of the moved displacement measuring device.
- the step (S2-1) of moving the end position of the displacement measuring device is such that, in order to measure the offset of the shim plate in the previous step (S1), the end positions of the displacement measuring device and the position controller of the position adjusting device are spaced apart by a predetermined distance in the longitudinal direction (x-axis direction) of the shim plate based on the front outer end of the lower die block. Therefore, in this step (S2), the end positions of the displacement measuring device and the position controller can be adjusted in the width direction (y-axis direction) and height direction (z-axis direction) of the lower die block.
- the position adjustment device can simultaneously move each end of the displacement measuring device and the position controller in the height direction (z-axis direction) of the lower die block and/or in the width direction (y-axis direction) by using a moving mechanism provided between a fixing member and a support member that fixes the displacement measuring device and the position controller.
- the present step (S2) can be performed simultaneously with the position movement and fixation of the displacement measuring device and the position controller.
- the displacement measuring device and the position controller whose positions are moved and fixed, can have their respective ends spaced apart from the front outer end of the lower die block by the same distance. That is, the ends of the displacement measuring device and the ends of the position controller can be spaced apart from the end of the shim plate by the same distance. Accordingly, the position controller can be precisely operated according to the offset of the shim plate measured by the displacement measuring device.
- This step (S3) measures the distance (L 1 ) to the front outer end of the lower die block, taking the position of the movable and fixed displacement measuring device as the zero point, i) then measures the distance (L 2 ) to the end of the shim plate, and iii) calculates their deviation (L 1 -L 2 ) to measure the offset of the shim plate before position adjustment.
- the offset of the shim plate may indicate a positive (+) value when the shim plate protrudes to the front outer side of the lower die block, and may indicate a negative (-) value when the end of the shim plate is positioned on the inside of the lower die block.
- the position adjustment method includes a step (S4) of adjusting the position of the shim plate according to the offset value measured using the position adjuster.
- This step (S4) refers to a step of comparing the offset value of the shim plate measured in the previous step (S3) with the preset position and/or offset of the shim plate, and adjusting the position of the shim plate to satisfy the preset position and/or offset of the shim plate when a deviation exists.
- the offset of the preset shim plate may be a value recalculated based on the distance (L 1 ) from the zero point of the previously measured displacement measuring device to the front outer end of the lower die block so as to have the same reference as the offset of the shim plate measured in the previous step (S3).
- this step (S4) can be performed by bringing the end of the position controller into contact with the end of the shim plate and then applying force to the end of the shim plate with the position controller along the longitudinal direction of the lower die block.
- the force applied to the end of the shim plate by the position controller may have different directionality depending on the preset position and/or offset of the shim plate and the offset of the shim plate measured in the previous step (S3).
- the force may be a force pulling outwardly of the lower die block when the end position (L pd ) of the preset shim plate, as shown in (b) of FIG. 9, is relatively further outwardly of the lower die block than the end position (L M ) of the shim plate measured in the previous step (S3).
- the position controller may have a slightly different operating position depending on the end position (L pd ) and/or offset of the preset shim plate and the end position (L M ) and/or offset value of the shim plate measured in the previous step (S3). Accordingly, the position controller may change position before contacting the end of the shim plate.
- the end of the position adjuster may be adjusted so that the end of the shim plate faces the end of the shim plate as in (a) of FIG. 10, but the lower end of the position adjuster is on the lower die block, and the position in the height direction (z-axis direction) of the lower die block can be adjusted.
- the position of the lower die block in the height direction (z-axis direction) can be lowered so that the boundary between the shim plate and the lower die block is located at the center of the end of the position adjuster, and then the end of the position adjuster and the end of the shim plate can be brought into contact.
- the present invention may include a magnetic member at the end of the position controller that comes into contact with the end of the shim plate, and correspondingly, the shim plate may be formed of a material that has ferromagnetism under magnetic field conditions.
- the position adjustment method includes a step (S5) of assembling the slot die coater by placing and fixing the upper die block on the position-adjusted shim plate.
