Description

Technical Field

[0001] The present invention relates to a separation device for a liquid nozzle and an air nozzle of a spray nozzle, and to a method of operating the separation device.

Background Art

[0002] A spray nozzle is a device for supplying an adhesive, and is particularly used when supplying a liquid adhesive having a low viscosity. This spray nozzle is connected to a dispensing device and has a function of atomizing an adhesive and spraying it onto a component to be adhered to thereby adhere the components to each other. It is mainly used in the semiconductor adhesion and assembly processes.

[0003] The nozzle member of a conventional spray nozzle mainly includes a liquid nozzle and an air nozzle. A liquid flow path through which an adhesive flows is formed inside the liquid nozzle. On the other hand, the air nozzle is attached so as to be overlapped outside the liquid nozzle, and a gas flow path is formed between the air nozzle and the liquid nozzle. When the adhesive is discharged through the liquid flow path, the adhesive is atomized by the air ejected through the gas flow path, and the atomized adhesive is applied to the component to be adhered.

[0004] In a spray nozzle provided with a liquid nozzle and an air nozzle, the outer wall surface of the liquid nozzle and the inner wall surface of the air nozzle are designed as inclined conical surfaces that fit each other in order to improve the concentricity after assembly. With such a design, it has become possible to spray the atomized adhesive uniformly. However, due to this inclined conical surface, the liquid nozzle and the air nozzle are in a structure where they are closely fitted, and as a result, it may be difficult to remove them. If an excessive force is applied or an attempt is made to forcibly separate them using tools, the liquid nozzle or the air nozzle may be deformed or the surface may be damaged. As a result, when assembling again, the assembly accuracy may decrease due to variations in dimensional tolerances, and in the worst case, gas leakage may occur.

[0011] FIGS. 1 to 3 show a separation device for a liquid nozzle and an air nozzle of the present invention. According to these drawings, such a separation device includes a fixed base 10, a drive wheel 20, a support base 30, an extrusion part 40, and two clamp parts 50.

[0012] As shown in FIGS. 3 and 4, the fixed base 10 is a hollow frame structure and has a support part 11 and an anti-slip part 14. The support part 11 has a vertical hole 12 formed so as to be recessed downward on its top surface and a screw hole 13 further penetrating downward at the bottom of the vertical hole 12. The anti-slip part 14 is provided at an interval below the support part 11 and has a protruding part 141 protruding toward the support part 11 at a position corresponding to the screw hole 13 of the support part 11. In a preferred embodiment of the present invention, the anti-slip part 14 is preferably detachably attached to the bottom of the fixed base 10, but is not limited thereto, and may be formed at the bottom of the fixed base 10 by integral molding.

[0013] The drive wheel 20 is installed below the support part 11 of the fixed base 10 and is disposed between the support part 11 and the protruding part 141 of the anti-slip part 14, and has a bolt 21 screwed and connected to the support part 11 through the screw hole 13 of the support part 11. Thereby, by rotating the drive wheel 20 clockwise or counterclockwise, the drive wheel 20 can be reciprocally moved between the support part 11 and the protruding part 141 of the anti-slip part 14. Further, the protruding part 141 of the anti-slip part 14 restricts the downward movement limit position of the drive wheel 20.

[0014] The support base 30 is installed on the top surface of the support portion 11 of the fixed base 10, and has a through hole 31, at least one rotation restricting groove portion 32, two lateral guide grooves 33, and two guide slots 34.

[0015] The through hole 31 is formed so as to penetrate from the top surface to the bottom surface of the support base 30, and its formation position corresponds to the vertical hole 12 of the support portion 11 of the fixed base 10. The at least one rotation restricting groove portion 32 is formed to be recessed in the inner wall of the through hole 31, and each of the at least one rotation restricting groove portion 32 extends vertically from the top surface to the bottom surface of the support base 30.

[0016] The two lateral guide grooves 33 are respectively arranged on both opposite sides of the through hole 31, penetrate the outer peripheral side surface of the support base 30, and extend horizontally. The two guide slots 34 are formed to penetrate the top surface of the support base 30, and each extends parallel to the two lateral guide grooves 33 corresponding thereto.

[0017] The extrusion component 40 is installed to be vertically movable in the vertical hole 12 of the fixed base 10 and the through hole 31 of the support base 30, and has a rod portion 41, a holding portion 42, a receiving recess 43, and two cut portions 44. The rod portion 41 is installed to penetrate the vertical hole 12 and the through hole 31. The holding portion 42 is recessed and formed at the top end of the rod portion 41 and is disposed on the top surface of the support base 30. The receiving recess 43 is recessed and formed at the top of the holding portion 42 of the extrusion component 40. The two cut portions 44 are formed to penetrate both opposite sides of the holding portion 42 of the extrusion component 40, communicate with the receiving recess 43, and the two cut portions 44 respectively correspond to the two guide slots 34 of the support base 30.

[0018] A vertical restoring spring 45 is attached to the rod portion 41 of the extruded part 40, and both ends of the vertical restoring spring 45 abut against the bottom surface of the support base 30 and the bottom end of the rod portion 41, respectively, providing a biasing force that moves the extruded part 40 downward, thereby causing the holding portion 42 to be in close contact with the support base 30. In a preferred embodiment of the present invention, the vertical restoring spring 45 is preferably a compression spring, but is not limited thereto.

[0019] Furthermore, the extruded part 40 is equipped with a regulating pin 46 inserted laterally into the rod portion 41. When the regulating pin 46 is inserted into the rod portion 41, at least one end of the regulating pin 46 protrudes into at least one rotation regulating groove 32 of the support base 30. As a result, the extruded part 40 can reciprocate up and down within the vertical hole 12 and the through hole 31, but it cannot rotate relative to the fixed base 10 or the support base 30. In a preferred embodiment of the present invention, there are two rotation regulating grooves 32 of the support base 30, and these two rotation regulating grooves 32 are each located on opposite sides of the through hole 31, with both ends of the regulating pin 46 protruding into the two rotation regulating grooves 32.

[0020] Each of the two clamp components 50 is installed so as to be movable, for example, slidable, within two lateral guide grooves 33 of the support base 30, and each clamp component 50 has an inner end, an outer end and a clamping claw 51, the inner end of the clamp component 50 facing the through hole 31 of the support base 30, the outer end of the clamp component 50 protruding outward through the outer peripheral side surface of the support base 30, and the clamping claw 51 is formed on the inner end of the clamp component 50 and protrudes from the top surface of the support base 30 through the corresponding guide slot 34 in the support base 30 and is facing toward the through hole 31.

[0021] A lateral restoring spring 52 is installed between the inner end of each clamp component 50 and the support base 30, and the lateral restoring spring 52 provides a biasing force that pushes the clamp component 50 outward from the support base 30. On the other hand, the clamping claws 51 protrude from the guide slot 34 of the support base 30, preventing the clamp component 50 from coming off the support base 30. In a preferred embodiment of the present invention, the lateral restoring spring 52 is preferably a compression spring, but is not limited thereto.

[0022] As shown in Figures 6 to 4, the liquid nozzle 61 and air nozzle 62 of the spray nozzle before separation are superimposed on each other, with the air nozzle 62 overlapping the outside of the liquid nozzle 61, and the flange 611 of the liquid nozzle 61 located outside the flange 621 of the air nozzle 62. In addition, two slits 622 are provided in the flange 621 of the air nozzle 62, and these two slits 622 are formed to penetrate both sides of the flange 621 of the air nozzle 62 along its radial direction.

[0023] The following describes in detail the method for separating the liquid nozzle 61 and the air nozzle 62 of a spray nozzle using the separation device of the present invention, with reference to Figure 10.

[0024] First, step 1 is to position the liquid nozzle 61 and air nozzle 62 to be separated. Specifically, the spray nozzles to be separated are first placed in the housing recess 43 of the extrusion part 40 so that the flange 611 of the liquid nozzle 61 and the flange 621 of the air nozzle 62 face downwards, and the two slits 622 of the air nozzle 62 are adjusted to correspond to the clamping claws 51 of the two clamp parts 50. At this time, the flange 611 of the liquid nozzle 61 is located below the flange 621 of the air nozzle 62.

[0025] Next is step 2, the step of pressing the clamp parts 50. As shown in Figures 7 and 8, the outer ends of the two clamp parts 50 are pressed in simultaneously, so that the two clamping claws 51 of the two clamp parts 50 pass through the two notches 44 provided in the holding part 42 of the extrusion part 40 and the two slits 622 of the air nozzle 62 and firmly contact the flange 611 of the liquid nozzle 61.

[0026] Finally, step 3 is the step of rotating the drive wheel 20. As shown in Figure 9, when the drive wheel 20 is rotated, the bolts 21 of the drive wheel 20 push the extrusion part 40 upward, and at this time the holding part 42 of the extrusion part 40 lifts the air nozzle 62, while the liquid nozzle 61 is fixed by the two clamp parts 50, so the air nozzle 62 is separated from the liquid nozzle 61.
