1. Scope
This specially designed unit keeps a certain distance from the lower surface
of the nozzle by moving the component scraping plate up and down,
depending on the height of each nozzle when the component is discharged,
and so enables mechanism change and control, in order to discharge the fine
components securely.
2. Specifications

Item Description
1. Functions
•
Based on the component thickness obtained from the component library and
the results of nozzle level automatic teaching, this plate is moved up and
down, so keepang the distance required for the removal of fine components,
from the nozzle lower surface.
2. Applicable
Machine
•
All models in TCM-X series
3. Applicable
Component
Component Thickness 0.1 mm or more
Note :
It does not apply to the components to be picked up with the nozzle
level set to "High" (Component Height 2.5 mm or more).
(The component discharge operation is performed while the component
scraping plate is set at the fixed position.)
4. Configurations
Installation of the component scraper for exclusive use is required.
•
Up and Down Movement Mechanism:
The motor, origin sensor, pulley, belt, component removing
plate, mounting brackets, etc., are to be added.
Note :
The adjustments for motor origin, stopper, belt tension and component
removing plate, etc., are required.
•
Support for PEC Recognition Camera
Note :
Readjustment for the PEC recognition camera is required.
•
Driving motor, motor breaker and electromagnetic contactor
5. Applicable
Software
Installations of the applicable software and soft switches on the main machine,
are required.
6. Others If it is attached on the TCM-X200BL, TCM-X100AL, TCM-X100JAL or
TCM-X300AL, the nozzle drop detection function is unavailable.

4. Operation Procedure
4.1 Preparation and Setup
(1) The gap distance between the nozzle and the component scraping plate
can be changed by setting when it is applied to the fine components.
(2) The height of the component scraping plate can be adjusted by
measuring the gap distance between the nozzle and the scraping plate,
using a thickness gauge.
(3) When this system is used, perform the automatic teaching of the nozzle
level periodically.
(4) When this system is used, setup the component library as correct as
possible.
(5) For this system, periodical maintenance including oiling is not required.

4.2 Control Action and Description
0606-001
4.2 Control Action and Description
(1) The position of the component scraping plate is moved up and down,
based on the component thickness obtained from the Component
Library Data, under the following conditions.
When the nozzle level is set to "Low", the action of the component
scraping plate is based on the nozzle height resultant from the automatic
teaching, so the distance from the nozzle lower surface is changed in
its controlling the gap with the nozzle, depending on the component
thickness.
When the nozzle level is set to "High" (more than 2.5 mm of
Component Thickness), the position of the component scraping plate is
located at the uppermost position within the moving range, regardless
of the nozzle height.
Also the gap distance can be set to the following three stages.
(Initial Setting: Approach Level 2)
Also, depending on each Approach Level, the gap distance can be fine-
adjusted within the range of 1 to 100%.
For the range of 1 to 100%, that is decided on the basis of the value of
the upper level of the selected level (ex: Level 1 in the case of Level 2),
as 0%, and the values of 100% for each Approach Level are shown in
Table 2.
In the case of Level 1, the level adjustment rate is ineffective, so the
value can not be closer than the value in Table 2.

Reference
When the level adjustment rate is set to 100%, the gap distance for the
component with the thickness of 0.24 mm is as follows: as Approach Level
1 = 0.06 [mm] and Approach Level 2 = 0.08 [mm]
Gap Distance = Approach Distance of the Upper Level + (Difference from
the value in Upper Level)

70/100 = 0.06 + (0.08 - 0.06)
