Bonding technology is a common technology in the semiconductor industry, and is to apply glue to a portion to be bonded (bonded) of a chip or a substrate, and then place another chip on the portion to be bonded, so that the chip and the substrate are bonded to each other, or the chip and the chip are bonded to each other.
The prior dispensing device comprises a body, a glue supply unit and at least one dispensing needle head, wherein the body is provided with at least one glue discharging channel. One end of the colloid discharging channel is coupled with the colloid supplying unit, and the other end of the colloid discharging channel is coupled with the colloid needle head. The glue supply unit provides glue, and the glue flows to the glue dispensing needle head through the glue discharge channel to perform a glue dispensing process.
Although the existing dispensing device can achieve the effect of dispensing, there are a number of disadvantages, such as:
the first disadvantage is that when the glue reaches the dispensing needle, the gravity and the pushing force of the subsequent glue are used to break through the surface tension to flow out of the dispensing needle for dispensing. When glue just flows out of the dispensing needle head, the accumulated pressure is larger, the glue outlet quantity is more in the moment because of breaking through the relation of the surface tension of the needle head, the glue outlet quantity gradually decreases after a period of time, the glue outlet quantity approaches to be stable after increasing to a certain degree, when the feeding at the front end is stopped, the residual pressure of the needle head is slowly released, and the glue can slowly overflow.
As described above, the dispensing needle has a problem that the dispensing amount is unstable and difficult to control when dispensing starts or ends.
The second disadvantage is that the glue is viscous fluid, so that the flowing speed or flow of the glue may be affected by external environmental factors such as temperature and humidity during the bonding process, or the glue supply unit, so that the glue output is inaccurate and not quantitative.
In summary, the above-mentioned shortcomings of the prior art, such as inability to stably and precisely discharge the glue, are becoming an urgent innovation in the industry.

Detailed Description
So that those skilled in the art can fully understand the technical features, contents and advantages of the present invention and their attained functions, the present invention will be described in detail with reference to the drawings and in the form of examples, wherein the drawings are used for illustration and description only, and not necessarily for the actual proportion and precise arrangement of the present invention after its implementation, so that the appended drawings should not be construed as limiting the scope of the present invention in practical implementation.
Fig. 1 is a schematic diagram of a glue dispensing device according to an embodiment of the invention, and as shown in the drawing, the glue dispensing device includes a base 10, a pressure control unit 11, a certain amount of glue supply unit 12, a dispensing needle 13, and a glue sensing unit 14.
The base 10 includes a pressure control chamber 100 and a glue tube 101. The pressure control chamber 100 is located inside the seat 10. The glue tube 101 is located inside the base 10 and extends from one end of the base 10 to the other end, and the glue tube 101 penetrates through the pressure control cavity 100. The glue tube 101 is a tube with elasticity or a rubber tube.
The pressure control unit 11 is an air compressor. The pressure control unit 11 is coupled to the pressure control chamber 100 of the base 10 through a connector 102. The fitting 102 may be a valve body, a bi-directional valve, or a tube.
The glue supplying unit 12 is disposed at one end of the base 10 and coupled to the glue tube 101. The glue dispensing unit 12 is a Mono pump (Mono pump) or a plunger pump (Piston pump). In one embodiment, if the glue supplying unit 12 is a moir pump, it includes a rotor 121 and a stator 120, and the stator 120 is located outside the rotor 121. The stator 120 is an elastomer. The rotor 121 is an eccentric screw. When the rotor 121 rotates, a cavity with the same cross-sectional area is formed, and the liquid conveyed in the cavity is divided into a packet, so that the glue feeding unit 12 has the advantage of stable volume feeding and is not influenced by the machine itself or external environmental factors during the bonding process.
If the glue supply unit 12 is a plunger pump, the plunger pump may be a single plunger pump, a horizontal plunger pump, an axial plunger pump, or a radial plunger pump. The single plunger pump comprises an eccentric wheel, a plunger, a spring, a cylinder body and two one-way valves. A closed volume is formed between the plunger and the cylinder hole. The horizontal plunger pump is mainly composed of a plurality of plungers (3 or 6) which are arranged in parallel, and a 1 crankshaft is used for directly pushing the plungers to reciprocate through a connecting rod sliding block or an eccentric shaft so as to realize the hydraulic pump for sucking and discharging liquid. An axial plunger pump (Piston pump) is a plunger pump in which the reciprocating direction of a Piston or plunger is parallel to the cylinder central axis. Radial plunger pumps are classified into pressure oil supply type and self-priming type. Radial plungers are divided into two main categories, pump valve flow and shaft flow.
In one embodiment, if the glue unit 12 is a plunger pump, the plunger pump is a positive displacement pump or a reciprocating pump. The plunger pump operates the fluid medium by a pressure differential created by a plunger reciprocating in a plunger cylinder resulting in a change in the sealing volume in the plunger cylinder. The throughput or flow rate of the fluid can be controlled by adjusting the pressure difference, so that the plunger pump can provide a fixed amount of glue through the control of the pressure difference and is not influenced by the machine itself or external environmental factors during the bonding process.
The dispensing needle 13 is disposed at the other end of the base 10 and coupled to the glue tube 101.
The glue sensing unit 14 is disposed on the dispensing needle 13 to sense the dispensing amount of the dispensing needle 13. The glue sensing unit 14 may be a proximity switch, a capacitive sensor or an optical sensor. The glue sensing unit 14 is electrically connected to the pressure control unit 11.
Please refer to fig. 2, which is a schematic diagram of the pressure control chamber 100 of the glue dispensing apparatus in a pressurized state according to an embodiment of the present invention, wherein before dispensing starts, the glue sensing unit 14 sends a glue dispensing message to the pressure control unit 11, and the pressure control unit 11 provides a pressurized air. The pressurized air enters the pressure control cavity 100 through the joint 102, so that the pressure in the pressure control cavity 100 is increased, the glue pipe body 101 is pressed to be compressed towards the inside, the glue in the glue pipe body 101 is extruded to the glue dispensing needle 13, the glue amount of the glue dispensing needle 13 is increased, the glue overcomes the surface tension and flows out of the glue dispensing needle 13, and in a very short time, the glue outlet amount is increased from less to stable output, so that the glue outlet amount in the initial stage of glue dispensing is gradually increased, and the subsequent glue overflow state can be eliminated.
If the pressure inside the pressure control chamber 100 cannot overcome the surface pressure by the glue after the pressurization, the pressure control unit 11 can provide the pressurized air to the pressure control chamber 100 again or continuously to raise the pressure inside the pressure control chamber 100, thereby increasing the force with which the glue tube 101 is compressed, so that more glue is compressed to the dispensing needle 13, and the surface pressure can be overcome.
In addition, after a period of time for dispensing, when the glue sensing unit 14 sends a message to the pressure control unit 11 that the dispensing amount has reached the standard, the internal pressure of the pressure control chamber 100 is gradually returned to the original unpressurized state, and the glue tube 101 is gradually returned to the unpressurized state. The internal pressure of the pressure control chamber 100 can return to the pressure control unit 11 through the joint 102, thereby returning the internal pressure of the pressure control chamber 100 to the original unpressurized state.
The glue dispensing unit 12 can stably and quantitatively supply glue, so that the speed of the glue outlet of the dispensing needle 13 can be kept stable, and the glue flow can be kept stable, thereby achieving the accurate and quantitative effect.
If the glue sensing unit 14 senses that the glue outlet amount of the glue dispensing needle 13 is abnormal, the glue dispensing needle 13 is blocked or stained when maintenance is required, or the glue dispensing process is required to stop the glue dispensing. The glue sensing unit 14 sends an abnormal signal to the pressure control unit 11.
Referring to fig. 3, which is a schematic diagram of a pressure control chamber of a glue dispensing apparatus in a pressure reducing state according to an embodiment of the invention, as shown in the drawing, the pressure control unit 11 provides a negative pressure (suction) and enters the pressure control chamber 100 through the connector 102 to reduce the internal pressure of the pressure control chamber 100. The glue tube 101 is affected by the low pressure control cavity 100, so that the glue tube expands outwards, so that the glue remains in the glue tube 101, and the glue dispensing needle 13 cannot flow out of the glue. The personnel involved can clean, maintain or replace the dispensing needle 13.
If the glue sensing unit 14 senses that the dispensing needle 13 still has glue flowing out, the glue sensing unit 14 sends an abnormal message to the pressure control unit 11, and the pressure control unit 11 further provides negative pressure to reduce the internal pressure of the pressure control chamber 100 again, so that the glue tube 101 is more expanded, and the glue cannot flow out from the dispensing needle 13.
As described above, if the pressure in the pressure control chamber 100 is reduced after the above-mentioned negative pressure, the glue still flows out from the dispensing needle 13, and the pressure control unit 11 can provide the negative pressure to the pressure control chamber 100 again or continuously to reduce the pressure in the pressure control chamber 100, so that the glue tube 101 is more expanded, and thus the glue cannot flow out from the dispensing needle 13.
If the maintenance, cleaning or replacement is completed, the pressure control unit 11 stops the pressure reduction, the internal pressure of the pressure control chamber 100 is gradually restored to the original non-reduced state, and the glue tube 101 is gradually restored to the unexpanded state. The pressure control unit 11 provides a positive pressure to the pressure control chamber 100 through the joint 102, or external air flows into the pressure control chamber 100 through the joint 102, so that the internal pressure of the pressure control chamber 100 returns to the original non-decompressed state, and the glue can flow out from the dispensing needle 13.
The method for discharging the adhesive according to one embodiment of the present invention comprises the following steps:
in the first step, the glue is stably supplied, please refer to fig. 1 again, and the glue supplying unit 12 supplies the glue to the dispensing needle 13 through the glue tube 101.
In the second step, the glue is precisely and quantitatively discharged, please refer to fig. 2 again, the glue sensing unit 14 sends a glue discharging message to the pressure control unit 11, and the pressure control unit 11 provides a pressurized air to enter the pressure control cavity 100 through the joint 102 to pressurize the glue tube 101. The pressurized air increases the pressure inside the pressure control cavity 100, so that the glue pipe body 101 is pressed and compressed towards the inside, and the glue inside the glue pipe body 101 is extruded to the dispensing needle 13, thereby increasing the glue amount of the dispensing needle 13, breaking through the surface tension, and flowing out of the dispensing needle 13 at a normal flow rate, and the glue output is improved from less to stable output in a very short time.
If the pressure inside the pressure control chamber 100 cannot overcome the surface tension of the glue after the above-mentioned pressurization, the pressure control unit 11 can provide the pressurized air to the pressure control chamber 100 again or continuously to increase the pressure inside the pressure control chamber 100, thereby increasing the force of the glue tube 101 being compressed and extruding more glue to the dispensing needle 13 to overcome the surface tension.
Step three, the pressure of the pressure control chamber 100 returns to normal pressure, if the glue sensing unit 14 sends a message to the pressure control unit 11 that the glue output reaches the standard, the internal pressure of the pressure control chamber 100 gradually returns to the original unpressurized state, and the glue pipe 101 gradually returns to the original state (i.e. the state not being extruded). The internal pressure of the pressure control chamber 100 can return to the pressure control unit 11 through the joint 102, thereby returning the internal pressure of the pressure control chamber 100 to the original unpressurized state.
In step four, referring to fig. 3 again when the glue sensing unit 14 senses that the glue dispensing amount of the glue dispensing needle 13 is abnormal, such as blocked or dirty, or when the glue dispensing needle 13 is to be repaired or replaced, the pressure control unit 11 provides a negative pressure to the pressure control cavity 100 to reduce the internal pressure of the pressure control cavity 100, so as to decompress the glue tube 101. The glue tube 101 is affected by the low pressure control cavity 100, so that the glue tube expands outwards, so that the glue remains in the glue tube 101, and the glue dispensing needle 13 cannot flow out of the glue. The personnel involved can clean, maintain or replace the dispensing needle 13.
If the pressure in the pressure control chamber 100 is reduced, the glue still flows out from the dispensing needle 13, and the pressure control unit 11 can provide the negative pressure to the pressure control chamber 100 again or continuously to reduce the pressure in the pressure control chamber 100, so that the glue tube 101 is more expanded, and the glue cannot flow out from the dispensing needle 13.
Step five, the pressure in the pressure control chamber returns to normal pressure, if the glue sensing unit 14 sends a message that the glue needle 13 has no abnormality to the pressure control unit 11, the pressure control unit 11 stops supplying negative pressure, the internal pressure of the pressure control chamber 100 gradually returns to the original unpressurized state, and the glue tube 101 gradually returns to the original state (i.e. unexpanded state). External air can enter the pressure control chamber 100 through the joint 102, thereby returning the internal pressure of the pressure control chamber 100 to an original non-depressurized state (i.e., an atmospheric state).
In summary, the present invention utilizes the pressure change of the pressure control chamber 100 to deform the glue tube 101, so that the present invention can achieve the effects of precise quantification and stable glue discharge.
