DETAILED DESCRIPTION
[0012] The illustrated present invention describes an embodiment of a tool 100 for dispensing fluid. The embodiment of the present invention comprises of a controller 150, a housing 108, a container 114, a means for providing rotational motion 102 and a dispensing mechanism 140. The present invention further includes an embodiment of an actuator 106 for controlling the dispensing mechanism 140, wherein the actuator 106 drives precision dispensing through controlled rotation of the means for providing rotational motion 102.
[0013] in a yet further embodiment, the present invention involves a housing 108 that is adapted to be in an open and close position for enclosing the container 114 and receiving the dispensing mechanism 140. The housing 108 has a locking feature to further secure the container 114 in place.
[0014] The present invention is connected to a controller ISO which is a computer or a system that is able to send and receive signals with relation to the operation of the tool 100 wherein the signals are in the form of instructions or commands. In another embodiment, the present invention comprises of a means for providing rotational motion 102 that further comprises of an actuator 106, a driven gear 119 and a drive gear 103. The signals sent to the actuator 106 is able to be used for dispensing fluid of varied viscosity through single configuration. The controller 150 sends the signals to the actuator 106 that is placed in the tool 100 for controlling the dispensing activity through controlled rotation as per the signal received whereas the driven gear 119 transfers the rotational movement from the means for providing rotational motion 102 to a rotary screw 115. The rotary screw 115 is positioned in a manner for linking the driven gear 119 to a plunger 112 wherein the rotary screw 115 initiates a linear movement to push the fluid out through the tip 109 for dispensing. [0015] in a yet further embodiment, the present invention includes a dispensing mechanism 140. The dispensing mechanism 140 includes a container 114, a key 110 and a plunger 112. The dispensing mechanism 140 further comprises of a motion translating mechanism 120 for translating rotational motion into combination of linear and rotational motion, a rotary screw 115 for iinking a gear 119 to a key 110.
[0016] The present invention describes a further embodiment of the dispensing mechanism 140 wherein the key 110 is aimed at affecting combination of rotational and linear motion to a plunger 112 and securing the motion translating mechanism 120 to the dispensing mechanism 140. Herewith, the key 110 comprises of an upper portion 111 and a lower portion 113. The lower portion 113 of the key 110 is configured in such a way that it complements an upper portion 111 wherein the lower portion 113 of the key 110 acts as a locking portion that compliments the upper portion 111. The key 110 portion is placed at the bottom of the rotary screw 115 wherein when the tool 100 is being used, the upper portion 111 of the key 110 is secured to the lower portion 113 of the key 110. The upper portion 111 and lower portion 113 of the key 110 disengage to allow removal of container 114 for refilling purpose. Apart from that, the present invention also further includes a plunger 112 that is attached at the lower portion 113 of the key 110. The plunger 112 is for preventing fluid from leaking out of dispensing body and to control precise dispensing of the fluid.
[0017] In another embodiment of the present invention, the dispensing mechanism 140 further comprises of a sensor 104. The sensor 104 is able to detect the position of the rotary screw 115 in order to determine the level of fluid in the container 114 As the fluid is dispensed, the rotary screw 115 moves to the bottom of the container 114 and when the fluid is depleted, the sensor 104 will send a signal back to the controller 150 to alert the user. The user then replaces the dispensing mechanism 140 to refill the fluid. The dispensing mechanism 140 further comprises of a container 114 with two ends that is used for storing the fluid for dispensing wherein the container 114 is made of stainless steel or plastic. The container 114 of the present invention is manufactured with a variable measurement that is able to contain fluid of varied volume. One end of the container 114 is built in a way that it allows fluid insertion whereas the other is a tapered end to form a tip 109. The tip 109 of the container 114 has ridged features to allow a cap to be screwed on when the tool 100 is not in use for dispensing. [0018] The process of dispensing and retracting fluid using the tool 100 is by configuring a means for providing rotational motion 102, fixing a motion translating mechanism 120 to the dispensing body, securing the dispensing body to a predetermined dispensing position in the housing 108 and rotating the means for providing rotational motion 102 for allowing fluid to be dispensed and retracted. The rotation of the rotary screw 115 can be achieved through the actuator 106 based on the rotation count signal that was sent by the controller 150. The rotational motion is then transferred to the rotary screw 115 which then rotates the plunger 112. When the dispensing mechanism 140 is fixed in place and the signal is received, the rotating motion will be translated to a combination of rotation and linear position in order to dispense the fluid. When the rotating motion is translated to a combination of rotation and linear motion, the upper portion 111 of the key 110 is placed on the lower portion 113 of the key 110 to be secured in place. The motions generated will affect the plunger 112 that enables the fractional force to be linearised for precision dispensing. On the other hand, during retraction, rotating the plunger 112 reversely retracts the fluid back into the container 114 wherein the upper portion 111 of the key 110 will be disengaged from the lower portion 113 of the key 110.
[0019] It would be apparent to a person having ordinary skilled in the art, the afore-described methods and components may be provided in many variations, modifications or alternatives to existing tools and systems. The principles and concepts disclosed herein may also be implemented in various manner which may not have been specifically described herein but which are to be understood as encompassed within the scope and letter of the following claims.
