Technology Field

[0001] The present invention relates to a syringe cooling device using a thermoelectric element. Background Technology

[0003] A dispenser as described above is a device that performs the function of spraying a certain amount of supplied dispenser liquid through a nozzle to accurately apply a set amount to the corresponding location of a target object, and is a device used for precise bonding or processing, such as in semiconductor manufacturing processes.

[0004] In such dispensers, a syringe filled with a resin dispenser liquid is placed, and it functions to inject the filler into the substrate through a needle at an appropriate amount and pressure.

[0005] The dispenser liquid filled in the syringe in this way must maintain a constant temperature so that it can be discharged normally through the nozzle.

[0006] If the dispenser liquid rises above a certain temperature, the solution expands, which can change the discharge volume, and as described above, there was a problem in that the discharge volume of the dispenser liquid could vary slightly depending on the temperature.

[0007] To prevent this phenomenon, various methods for cooling syringes have been disclosed, but there were problems such as the structure of the cooling device being complex and the size of the cooling device becoming large. The problem to be solved

[0009] The present invention has been devised to solve the above-mentioned problems, and the objective of the present invention is to provide a syringe cooling device using a thermoelectric element that cools the syringe and maintains a constant temperature even if the temperature of the dispenser liquid stored in the syringe rises above a reference value by mounting a thermoelectric element between the syringe and the cooling unit.

[0014] It includes an air flow delay unit formed on the front inner side of the cooling unit, which increases cooling efficiency by delaying the air flow while switching the air flow supplied through the air circulation unit in the forward and reverse directions.

[0015] The air flow delay section comprises: an inlet through which air is introduced via a supply passage of the cooling section; a first passage through which air is introduced from the inlet and undergoes primary heat exchange; a passage extending from the first passage to allow air to move; a second passage through which air is introduced from the passage and undergoes secondary heat exchange; and an outlet extending from the second passage to allow air to be discharged to a discharge passage of the cooling section.

Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0022] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0023] First, FIG. 1 is an overall configuration diagram of a syringe cooling device using a thermoelectric element according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of a syringe cooling device using a thermoelectric element according to an embodiment of the present invention. FIG. 3 is a front cross-sectional view of a syringe cooling device using a thermoelectric element according to an embodiment of the present invention. FIG. 4 is a side cross-sectional view of a syringe cooling device using a thermoelectric element according to an embodiment of the present invention. FIG. 5 is a plan cross-sectional view of a syringe cooling device using a thermoelectric element according to an embodiment of the present invention.

[0024] A syringe cooling device using a thermoelectric element according to one embodiment of the present invention comprises a syringe (100), a contact part (200), a thermoelectric element (300), a cooling part (400), and an air circulation part (500).

[0025] The above syringe (100) is filled with a certain amount of dispenser liquid inside.

[0026] The dispenser liquid may be a UV coating liquid, silicone, paraffin, thermal runaway prevention liquid material, etc.

[0027] The dispenser liquid stored inside the syringe (100) is sensitive to temperature.

[0028] When the temperature of the dispenser liquid is 28°C or higher, the solution expands, and the dispenser liquid in this expanded state results in a difference in the valve discharge amount. Therefore, the temperature inside the syringe (100) must always be maintained at 24°C.

[0029] The above contact portion (200) is the surface to which the thermoelectric element (300) is in contact.

[0030] The contact portion (200) can be formed by cutting a portion of one side of the syringe (100).

[0031] That is, the above syringe (100) has a cylindrical cross-section, and in order for the thermoelectric element (300) to be in close contact, a flat surface must be formed, and accordingly, a part of the syringe (100) is cut to form a flat contact portion (200).

[0032] If the contact portion (200) is formed as a curve, the thermoelectric element (300) cannot be precisely contacted, and in this case, the heat generated from the syringe (100) may not be effectively cooled.

[0033] The thermoelectric element (300) is accommodated in the receiving space of the cooling part (400) as the contact part (200) is in close contact.

[0034] The thermoelectric element (300) is a device that absorbs heat from a low-temperature heat source and gives heat to a high-temperature heat source, and can implement the Seebeck effect, which is a phenomenon in which an electromotive force is generated by a temperature difference, or the Peltier effect, which is a phenomenon in which heat absorption or heat generation occurs by an electric current.

[0035] Specifically, the interior of the thermoelectric element (300) is a device composed of an N-type semiconductor having a large amount of electrons (negative charge) and a P-type semiconductor having a large amount of holes (positive charge). Depending on the direction of the applied current, one side of the thermoelectric element performs a heating operation in which the charge inside the thermoelectric element increases and heats up, while the other side performs an endothermic operation in which the charge relatively decreases and cools down.

[0036] The thermoelectric element (300) has a first surface (310) that is in contact with the contact portion (200), and a second surface (320) that is in contact with the inner surface of the case (410) of the cooling portion (400).

[0037] When current is applied to the contact portion (200) in contact with the first surface (310) of the thermoelectric element (300) so that a heat absorption operation is performed, the first surface (310) can provide cold heat to the contact portion (200).

[0038] When current is applied to the contact portion (200) in contact with the first surface (111) of the thermoelectric element (300) to perform a heating operation, the first surface (310) can provide heat to the contact portion (200).

[0039] Additionally, the cooling unit (400) can be fixed to one side of the syringe (100).

[0040] The cooling portion (400) accommodates a thermoelectric element (300) that is in contact with the contact portion (200) and can be fixed to the outer surface of the syringe (100).

[0041] The cooling section (400) may include a case (410), a receiving space (420), a supply passage (430), and a discharge passage (440).

[0042] The above case (410) is in close contact with one side of the syringe (100) and is secured through a bolt.

[0043] That is, a thermoelectric element (300) may be mounted on the rear of the case (410), and an air circulation section (500) may be formed on the front of the case (410).

[0044] The above receiving space (420) can be formed on the rear inner side of the case (410).

[0045] The receiving space (420) can accommodate a thermoelectric element (300), and the thermoelectric element (300) can be attached to the contact portion (200) without protruding to the outside of the case (410).

[0046] The supply passage (430) is formed on the front inner side of the case (410) and is located at the top of the case (410).

[0047] The above supply passage (430) receives external air through the air circulation unit (500).

[0048] The above discharge passage (440) is formed on the front inner side of the case (410) and is located at the bottom of the case (410).

[0049] The exhaust passage (440) can regulate the temperature by discharging heat-exchanged air from inside the case to the outside.

[0050] The supply passage (430) and the exhaust passage (440) can be connected to each other, and external air can be circulated.

[0051] The rear of the above case (410) may include a contact surface (450).

[0052] The above-mentioned contact surface (450) is formed at the rear of the case (410) with the same diameter as the outer surface of the syringe (100) and is a surface that comes into close contact with the syringe (100). Accordingly, since the contact surface (450) and the outer surface of the syringe (100) are formed with the same diameter, the formation of a gap is prevented, thereby preventing a decrease in cooling efficiency.

[0053] The interior of the supply passage (430) may include heat dissipation partitions (460) that are formed at regular intervals and are staggered from each other.

[0054] As the air supplied through the supply passage (430) passes through the heat dissipation partition (460) and moves between the upper and lower parts inside the supply passage (430), the heat exchange time can be increased.

[0055] In addition, the air circulation unit (500) supplies external air into the cooling unit (400), cools the heat-exchanged air, and then discharges it to the outside.

[0056] The air circulation unit (500) may include a supply pipe (510) and a discharge pipe (520).

[0057] The above supply pipe (510) is supplied with ambient air from an external air supply device (not shown).

[0058] A nipple is connected to one end of the supply pipe (510), and the end of the nipple is connected to the supply passage (430) of the cooling unit (400), and the other end of the supply pipe (510), which is formed to a certain length, is connected to an air supply device to supply air to the supply passage (430).

[0059] The above discharge pipe (520) has a nipple connected to one end, similar to the supply pipe (510), and the end of the nipple is connected to the discharge passage (440) of the cooling unit (400), and the other end of the discharge pipe (520), which is formed to a certain length, is connected to an air supply device so that air that has undergone heat exchange inside the cooling unit (400) is discharged.

[0060] A suction fan (522) may be installed inside the above-mentioned exhaust pipe (520) or air supply device.

[0061] The suction fan (522) can operate according to the opening signal of the supply volume control valve (900). That is, when the supply volume control valve (900) is opened, the suction fan (522) can operate to discharge air to the outside.

[0062] The amount of air sucked by the suction fan (522) can vary depending on the degree of opening of the supply volume control valve (900).

[0063] Additionally, referring to FIG. 6, an air flow delay section (600) may be further included in the front inner side of the cooling section (400).

[0064] The air flow delay section (600) can be configured to connect the supply passage (430) and the discharge passage (440) inside the cooling section (400).

[0065] The air flow delay section (600) continuously switches forward and reverse directions until the air supplied through the supply passage (430) is discharged through the discharge passage (440), thereby heat-exchanging the air that has risen to 24°C or higher.

[0066] The air flow delay section (600) is formed continuously at a constant interval between the supply passage (430) and the discharge passage (440).

[0067] The air flow delay section (600) includes an inlet (610), a first passage (620), a moving passage (630), a second passage (640), and an outlet (650).

[0068] The above inlet (610) is connected to the supply passage (430) to receive air.

[0069] The inlet (610) is formed with a slant in one direction.

[0070] The first passage (620) extends from the inlet (610) to form a curved surface.

[0071] Air introduced into the first passage (620) is guided along the curved surface and rotates, and heat is exchanged with the air heated by the heat generated by the thermoelectric element (300).

[0072] The above-mentioned passageway (630) is extended and formed on one side of the first passageway (620).

[0073] The passageway (630) is formed at an angle opposite to the inlet (610) and may be connected to the inlet (610).

[0074] The passageway (630) is a space where the heat-exchanged air from the first passageway (620) moves downward to the exhaust passageway (440).

[0075] Since the above-mentioned passage (630) is formed at an angle opposite to the inlet (610), the air that has been heat-exchanged through the first passage (620) does not move directly downward, but instead changes the direction of the airflow to move in the reverse direction, thereby delaying the time for heat exchange.

[0076] Accordingly, the time for cooling the air inside the cooling section (400) can be increased to increase the heat exchange efficiency.

[0077] The second passage (640) extends from the moving passage (630) to form a curved surface.

[0078] The second passage (640) can be extended in the opposite direction to the passage (630).

[0079] Air introduced into the second passage (640) is guided along the curved surface and rotates, and heat is exchanged with the air heated by the heat generated by the thermoelectric element (300).

[0080] That is, the air that has been heat-exchanged in the second passage (640) does not move directly to the discharge passage (440), but instead changes the direction of the airflow to move, thereby delaying the time for heat exchange, and consequently increasing the time for cooling the air, thereby increasing the heat exchange efficiency.

[0081] The above-mentioned outlet (650) is formed as an extension from the second passage (640) and is connected to the discharge passage (440). Accordingly, heat-exchanged air can be discharged through the second passage (640) to the discharge passage (440).

[0082] Additionally, referring to FIG. 7, it may include a sub-supply pipe (660) that branches off from the supply pipe (510) and connects to the inlet (610) of the air flow delay section (600).

[0083] When heat is exchanged starting from the supply passage (430), the temperature of the heat-exchanged air increases as it goes toward the lower part of the air flow delay section (600), so the heat exchange efficiency may decrease at the lower part of the air flow delay section (600). However, since the sub-supply pipe (660) is connected to the middle part of the air flow delay section (600) and ambient temperature is supplied, stable heat exchange can be achieved at both the upper and lower parts of the air flow delay section (600).

[0084] Therefore, by allowing sufficient heat exchange to occur as the air moves in the forward or reverse direction through the air flow delay unit (600), the temperature of the dispenser liquid stored in the syringe (100) can be stably maintained.

[0085] Additionally, a cover (700) may be further included in front of the cooling unit (400).

[0086] The above cover (700) closes the front of the case (410) and seals the supply passage (430) and the discharge passage (440).

[0087] The cover (700) is divided into a fixed part (710) and a sealing part (720), the fixed part (710) is a surface that adheres to the inside of the case, and the sealing part (720) seals the air flow delay part (600).

[0088] The above cover (700) has fastening holes formed at each corner, and a fixing bolt is fastened through the fastening holes to fix the cover (700) to the cooling unit (400).

[0089] Additionally, a detection sensor (800) may be further included on one side of the cooling section (400) where the discharge passage (440) is located.

[0090] The above detection sensor (800) detects the temperature of the heat-exchanged air discharged through the discharge passage (440).

[0091] A supply volume control valve (900) may be further included on the supply pipe (510).

[0092] The above supply volume control valve (900) controls the amount of air supplied according to the temperature inside the cooling unit (400).

[0093] For example, if the air temperature inside the exhaust passage (440) rises above a reference value through detection by the detection sensor (800), the detected temperature data is transmitted to a control unit (not shown), and the control unit controls the supply volume control valve (900) to increase the air supply volume.

[0094] Conversely, if the heat-exchanged air inside the exhaust passage (440) is below a reference value, the detected temperature data is transmitted to the control unit, and the control unit controls the supply volume control valve (900) to reduce the amount of air supplied, thereby enabling the air to be cooled stably.

[0095] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
