A technology of continuously dispensing the adhesive (2) using one is being applied.

This line dispenser (1) is a device that continuously dispenses the adhesive (2), and is controlled to continuously spray the adhesive (2) using a pump such as a screw pump.

Accordingly, as shown by the arrow in FIG. 1A, continuous application is performed on the applied portion 3 while moving the line dispenser 1 along the area or line where application of the adhesive 2 is required.

However, in the case of adhesive application through continuous dispensing, as shown in FIG. 1b, the starting position (SP) of the line dispenser 1 and the end of the spraying of the line dispenser 1 It is difficult to precisely control the spraying to maintain a uniform thickness (t) between end positions (EP), so by additionally moving the line dispenser (1) in a predetermined length or area (L), the adhesive (2) was sprayed so that it partially overlapped each other at the start and end positions.

Through this overlapping spraying, it is possible to solve the problem of areas or lines where the adhesive 2 is not sprayed, but the thickness (t) of the applied adhesive 2 in the overlapping area is different in height. More and more problems were created.

Furthermore, this problem of increasing thickness runs counter to the recent trend in which equipment through which the adhesive 2 is sprayed must be manufactured precisely, causing a problem of deteriorating assembly quality.

Figure 2 is a block diagram showing a hybrid dispensing system according to an embodiment of the present invention.

Referring to FIG. 2, the hybrid dispensing system 10 (hereinafter referred to as the dispensing system) according to the present embodiment dispenses the adhesive to the applied portion 3, and includes a dispensing unit 100, It includes a control unit 200, a position alignment unit 300, and a determination unit 400.

The dispensing unit 100 includes an exchange unit 110, a first dispenser 120, and a second dispenser 130.

The first dispenser 120 sprays the adhesive onto the area or line that needs to be applied to the applied portion 3, and the first dispenser 120 is in contact with the applied portion 30. Spray adhesive.

In this case, the state in contact with the applied portion 30 means that the adhesive discharged from the spray portion 121 of the first dispenser 120 (see FIG. 4A) is continuously discharged from the spray portion 121. , refers to a state in which the discharged adhesive is continuously contacted and sprayed on the applied portion 30.

That is, even if the injection unit 121 itself does not directly contact the application area 30, the adhesive is in direct contact with the application area 30 and is continuously sprayed. In this way, the first The dispenser 120 continuously sprays the adhesive onto the applied portion 3.

Meanwhile, in a state where the first dispenser 120 continuously sprays the adhesive onto the applied portion 3 as described above, the first dispenser 120 is transferred along a preset path, and as a result, the adhesive 1 The adhesive sprayed through the dispenser 120 is line dispensed on the applied portion 3.

The first dispenser 120, which performs such line dispensing, may be driven by, for example, a screw pump to continuously discharge the adhesive.

Furthermore, the detailed configuration of the first dispenser 120 may vary, and it is sufficient to continuously discharge the adhesive to the applied portion 3.

The second dispenser 130 sprays the adhesive to the area or line that needs to be applied to the applied portion 3, but sprays the adhesive in a state that does not contact the applied portion 30, that is, in a non-contact state. .

In this way, the second dispenser 130 sprays the adhesive in a non-contact state, performing so-called jet dispensing or drop dispensing.

That is, the spraying part 131 (see FIG. 4b) of the second dispenser 130 jet-dispenses or drop-dispenses the adhesive 132 while being spaced a predetermined distance away from the applied part 3. The adhesive 132 discharged in this way is laminated on a predetermined area or line of the applied portion 3.

In order to spray the adhesive through non-contact discontinuous dispensing as described above, the second dispenser 130 may use, for example, a piezoelectric jet dispensing method.

In this case, the detailed configuration of the second dispenser 130 may vary, and it is sufficient to discharge the adhesive to the applied portion 3 using a jet dispensing method.

In this case, the adhesive sprayed by the first and second dispensers 120 and 130 may be, for example, liquid silicone that induces sealing and adhesion between modules. However, it is obvious that the sprayed adhesive is not limited to this, and various adhesive materials can be used.

The exchange unit 110 operates the second dispenser 130 after the operation of the first dispenser 120 ends, or, conversely, operates the first dispenser 130 after the operation of the second dispenser 130 ends. To operate 120, the dispensers 120 and 130 are exchanged and placed in the spraying position.

In this case, the exchange unit 110 may be configured similarly to a tool exchange device in a conventional machine tool, but is not limited thereto, and the first and second dispensers 120 and 130 may be used as necessary. It can be designed in various ways as long as it can be exchanged for injection positions.

The position alignment unit 300 aligns the first dispenser 120 and the second dispenser 130 to the adhesive application position on the applied portion 3, and although not shown, a separate alignment marker or Sensors, etc. are additionally provided to accurately align the spraying positions of the dispensers 120 and 130.

As will be described later, the first dispenser 120 is moved between the start position and the end position, and is moved so that a predetermined gap (gap, G) is formed between the start position and the end position. Accordingly, the position alignment unit 300 aligns the first dispenser 120 so that it can be accurately aligned and positioned at the start position, and recognizes when the first dispenser 120 is located at the end position to Cognitive information is provided to the control unit 200.

In addition, in the case of the second dispenser 130, spraying is performed on the gap G formed between the start position and the end position. For this purpose, the position alignment unit 300 is connected to the second dispenser 130. ) is aligned so that it is located on the gap (G).

The determination unit 400 determines whether the adhesive sprayed onto the gap G is flat and has the same height or thickness as the surrounding adhesive, and provides the determination result to the control unit 200.

That is, the adhesive sprayed through the first dispenser 120 is not sprayed on the gap G, and the adhesive sprayed through the second dispenser 130 is sprayed in a form that fills the gap G. , it is necessary to determine whether the adhesive sprayed into the gap G is formed at the same height or thickness as the adhesive sprayed from the surrounding area.

Accordingly, the determination unit 400 senses the height or thickness of the adhesive and determines whether the surrounding adhesive and the adhesive provided in the gap G are formed entirely flat. In this case, the determination unit 400, although not shown, may be a sensor such as a separate camera, but is not limited thereto.

Meanwhile, the control unit 200 controls the overall operation of the dispensing unit 100, and for this purpose, it uses information obtained from the position alignment unit 300 and the determination unit 400.

That is, the control unit 200 operates the first dispenser 120 based on the information that the first dispenser 120 is located and aligned at the start position, and the first dispenser 120 operates at the end position. Based on the information that it is located and aligned, the operation of the first dispenser 120 is stopped.

Additionally, the control unit 200 controls an exchange operation command to the exchange unit 110 that performs exchange between the first and second dispensers 120 and 130.

Furthermore, the control unit 200 operates the second dispenser 130 based on information that the second dispenser 130 is positioned and aligned on the gap. Additionally, when the determination unit 400 determines that the adhesive has been formed evenly on the gap through the injection of the second dispenser 130, the operation of the second dispenser 130 is stopped.

Below, a hybrid dispensing method using the hybrid dispensing system 10 will be described.

FIG. 3 is a flowchart showing a hybrid dispensing method using the hybrid dispensing system of FIG. 2. FIGS. 4A and 4B are perspective views each showing a dispensing state using a first dispenser and a second dispenser in the hybrid dispensing method of FIG. 3. Figures 5A to 5D are schematic diagrams showing the spraying state of the adhesive in dispensing using the hybrid dispensing method of Figure 3.

First, referring to FIGS. 3, 4A, and 5A, in the hybrid dispensing method (hereinafter referred to as the dispensing method), the position alignment unit 300 moves the first dispenser 120 to the starting position (SP). ) (step S10).

Afterwards, referring to FIGS. 3, 4A, and 5A, the control unit 200 operates the first dispenser 120, and the first dispenser 120 moves from the start position (SP) to the end position (SP). EP), the first adhesive 122 is dispensed in the direction shown by the arrow in FIG. 5A (step S20).

In this case, as shown in FIG. 4A, the first dispenser 120 moves along the edge of the applied portion 3 and dispenses the first adhesive from the start position (SP) to the end position (EP). Dispense (122).

As previously described, the dispensing of the first adhesive 122 through the first dispenser 120 is a contact-type continuous dispensing, and the first adhesive 122 is continuously dispensed at the starting position (SP). It is sprayed from to the end position (EP).

Meanwhile, the start position (SP) and the end position (EP) do not overlap each other identically, and are formed to have a predetermined gap (G), as shown in FIG. 5A.

Therefore, the injection of the first adhesive 122 through the first dispenser 120 is not performed on the area or line defined by the gap G.

Thereafter, referring to FIGS. 3 and 4B, the exchange unit 110 exchanges the first dispenser 120 with the second dispenser 130, and the second dispenser 130 is replaced by the position alignment unit 300. The dispenser 130 is aligned in its position on the gap G (step S30).

Afterwards, referring to FIGS. 3, 4B, and 5B, the control unit 200 operates the second dispenser 130, and the second dispenser 130 dispenses a second adhesive ( 132) is dispensed (step S40).

In this case, dispensing of the second adhesive 132 through the second dispenser 130 is jet dispensing, as described above, and the second adhesive 132 is discontinuously dropped and fills the gap. Part (G) is filled in.

Meanwhile, the gap (G) area can be formed in various ways, and in some cases, the second dispenser 130 fills the gap (G) evenly within a predetermined range from the upper part of the gap (G) area. can be moved

Jet dispensing by the second dispenser 130 is performed until the adhesive in the gap G area is flattened in the determination unit 400 (step S50).

That is, as shown in FIG. 5C, the second adhesive 132 sprayed into the gap G is at the same height as the first adhesive 122 sprayed from the start position SP to the end position EP. Alternatively, the determination unit 400 determines whether it is formed to a thickness t, and when the flattening is completed (step S50), the dispensing process ends.

Meanwhile, the second adhesive 132 drop-injected into the gap G is substantially the same material as the first adhesive 122, and is a liquid with a predetermined viscosity, so it forms around the adhesive over time. It is integrated with the first adhesive (122). Therefore, as shown in FIG. 5D, the position where the gap G was formed is flattened 140 so as not to be identified as a whole, and is formed uniformly throughout the area where the application portion 3 was applied.

Figure 6 is an example of an adhesive being sprayed onto a vehicle ECU module through the hybrid dispensing method of Figure 3.

In Figure 6, the result of applying the adhesive 140 to, for example, a vehicle ECU (electronic control unit) module as the application area 3 through the dispensing method according to this embodiment is illustrated.

That is, as shown in FIG. 6, the adhesive 140 is flattened and formed at the same height along the edge of the applied portion 3, and a separate step or height is formed on the line where the adhesive 140 is formed. No changes are confirmed.

As described above, through this embodiment, the adhesive can be formed at a uniform height, and through this, sealing or assembly can be performed more uniformly and effectively.

According to the embodiments of the present invention as described above, the problem of increasing thickness due to adhesive overlap between the start and end positions in the conventional dispensing system is solved, and the thickness is the same between the start and end positions as at other positions. The adhesive can be applied with.

In other words, the adhesive is applied continuously through line dispensing from the start position to the end position, and the adhesive is dropped through jet dispensing only in the gap between the start and end positions, forming the adhesive at a constant thickness. By spraying the adhesive until the adhesive is applied, not only can the adhesive be applied to the entire thickness at the same thickness, but the adhesive application process time can also be minimized.

Therefore, by uniformly applying an adhesive used for sealing various modules, such as liquid silicone, assembly quality and process efficiency can be improved, and defects can be minimized.

Although the present invention has been described above with reference to preferred embodiments, those skilled in the art can make various modifications and changes to the present invention without departing from the spirit and scope of the present invention as set forth in the following patent claims. You will understand that it is possible.
