Adhesive applicator with mixing function and suction function for various types of adhesives}

This technology applies an adhesive for fixing and adhering a battery module to an electric vehicle, but generates a mixed adhesive by mixing different adhesive compositions supplied in equal amounts. After applying the created mixed adhesive, the remaining mixed adhesive is forcibly sucked. It relates to an adhesive application device that has the function of discharging to the outside.

Recently, the need for carbon neutrality is increasing in response to climate change caused by global warming.

Carbon neutrality refers to the concept of reducing the use of carbon-emitting fuels such as oil and coal as much as possible and reducing carbon emissions to zero when necessary. To this end, the need and demand for electric vehicles as an alternative to internal combustion engine vehicles is increasing.

Electric vehicles use electricity as a power source, so large-capacity batteries are essential for long-distance and long-term driving. Therefore, they are manufactured with a large-capacity battery pack installed in the lower part of the vehicle body.

For example, as can be seen in Publication Patent No. 10-2018-0047791 and Publication No. 10-2013-0119764, a battery pack for an electric vehicle consists of several battery modules mounted on a tray of the battery pack case, The battery module consists of a collection of multiple battery cells.

When the above-described battery module is mounted on the tray, the bottom surface is treated to prevent dust, and then the case cover is attached with adhesive and fixed with bolts. At this time, the adhesive application to the tray must be done accurately to protect the entire battery pack. Assembly becomes possible, and the adhesive can also be used for adhesion between the body of an electric vehicle and the battery module.

To this end, the application means for applying the adhesive must have the ability to evenly distribute the adhesive on the vehicle body.

On the other hand, in the conventional adhesive device, after applying adhesive to the car body to form a coating layer, there is a residual amount inside, and during the movement of the adhesive device, due to the drop phenomenon, unwanted adhesive leaks out and causes surface damage. A problem arises that prevents even application of the adhesive, and additionally, a phenomenon in which some of the remaining adhesive adheres to the adhesive device may occur, resulting in a problem in which the adhesive layer is not evenly applied.

In addition, when it is desired to use a mixed adhesive that mixes compositions of different properties (e.g., base material and hardener), the mixed adhesive is prepared in advance and then provided to the adhesive device, so it depends on the ratio of the mixed composition. Since the pretreatment process requires a lot of time, problems arise that make it unsuitable for mass production.

Domestic registered patent No. 2282253 (announcement date: 2021.07.27.) Domestic Published Patent No. 2019-7856 (Publication date: 2019.01.23.)

Hereinafter, with reference to the attached drawings, an adhesive application device (hereinafter simply referred to as 'applicator') having a function for mixing different types of adhesives and a suction function according to the present invention will be described in detail.

Prior to the explanation, the different types of adhesive compositions described below are explained using the main agent and curing agent as an example, but this is only an example, and it is possible to use other types of adhesive compositions as needed.

First, as shown in FIGS. 1 and 5, the coating device 1 according to the present invention largely includes a supply member 100 and a nozzle member 200, and the supply member 100 includes a control unit (not shown). Different types of adhesive compositions are supplied simultaneously through a control signal (not shown), and the nozzle member 200 forcibly suctions the mixed adhesive remaining inside and discharges it to the outside.

To explain in more detail, the supply member 100, as shown in FIGS. 2, 3, and 5, is configured such that different types of adhesive compositions individually supplied from the outside are simultaneously supplied to the nozzle member 200, which will be described later, in the same amount. The configuration for allowing inflow includes a supply body 110, a solenoid valve 120, and a connection socket 130.

For example, as shown, the supply body 110 is equipped with a solenoid valve 120 on the upper part to be replaceable, and a pair of connection sockets 130 are removably mounted on both sides so that different types of adhesive compositions can be used in the solenoid valve 120. ) Depending on whether it is open or closed, it is simultaneously supplied through the connection socket 130 so that it can be supplied to the static mixer pipe 211 constituting the nozzle member 200.

For this purpose, a moving path is formed inside the supply body 110 so that the different adhesive compositions, in which the aid and hardener are individually supplied through a pair of connection sockets 130, are mixed and flowed into the static mixer pipe 211. The movement path includes the first movement path 111, the second movement path 113, and the third movement path 115.

As shown, the first moving path 111 consists of a pair, each starting from the upper surface of the supply body 110 and formed in a vertical direction connected to the second moving path 113, and each first moving path 111 Inside the furnace 111, a connection socket 130 and a rod 121 are inserted to be able to be raised and lowered so that whether the joint connected to the second moving passage 113 is opened or closed can be determined.

The second moving path 113 is composed of a pair corresponding to the number of the first moving path 111, with one side of each starting from the side of the supply body 110 and the other side of each being connected to the third moving path 115. It is formed so that it can be connected.

At this time, as shown, the second moving path 113 is formed to have a downward slope so that the adhesive composition injected by the elevation of the rod 121 can be easily supplied to the third moving path 115. It is desirable to have.

As shown, the upper part of the third moving path 115 is in communication with a pair of second moving paths 113, and the lower part is connected in communication with the inside of the static mixer pipe 211 so that different adhesive compositions are combined. So that it can be supplied inside the static mixer pipe 211.

In addition, the solenoid valve 120 collectively controls a pair of rods 121 each inserted into the pair of first moving passages 111 in response to a control signal from the control unit to move the third moving passage 113 through the second moving passage 113. It is configured to ensure that the different types of adhesive compositions flowing into the moving passage 115 are supplied in the same amount.

For this purpose, the solenoid valve 120 is electrically connected to the control unit, and as shown, a rod 121 is inserted into each pair of first moving passages 111 so as to be capable of being raised and lowered, and the third Different types of adhesive compositions are supplied to the moving path 115 under the same conditions and supply amounts.

Here, the solenoid valve 120 can control the pair of rods 121 to go up and down in stages so that the supply amount can be adjusted.

In addition, a pair of connection sockets 130 is provided on both sides of the supply body 110 so that they can be individually inserted into the pair of second moving paths 113, and one of each connection socket 130 is supplied with the subject matter. A curing agent is supplied to the other so that different types of adhesive compositions are supplied to one supply body 110.

And, as shown in FIGS. 4 to 8, the nozzle member 200 obtains a mixed adhesive mixed with different adhesive compositions flowing in through the above-described supply member 100, and then applies the obtained mixed adhesive to electricity. It is applied evenly to the car so that the battery module can be adhered, but after application, the mixed adhesive remaining in the nozzle member 200 is forcibly sucked in and discharged to the outside. The nozzle pipe 210, the nozzle 220, and Includes a suction cylinder (260).

For example, as shown, the nozzle pipe 210 includes an exterior 215 and a static mixer pipe 211 provided to surround the exterior 215, and the open top of the static mixer pipe 211 is It is coupled in communication with the third moving path 115 so that different types of adhesive compositions can be supplied.

Through this, the heterogeneous adhesive composition supplied to the static mixer pipe 211 passes through a plurality of elements 213 formed in the longitudinal direction of the static mixer pipe 211 in a shape that is alternately twisted to the left and right to the nozzle 220. ), making it possible to create a mixed adhesive in which different types of adhesive compositions are mixed without separate power (for example, the power required for rotation).

As shown, the nozzle 220 coupled to the open lower part of the static mixer pipe 211 allows the mixed adhesive produced through the distribution hole 251 to be discharged with a predetermined width.

To this end, the nozzle 220 in the present invention includes a receiving body 230, a cover 240, and a distribution plate 250.

As shown, the receiving body 230 is formed with a receiving space 231 for temporarily receiving the mixed adhesive supplied through the static mixer pipe 211.

In addition, a distribution space 233 having a groove shape is formed on the outer surface of the receiving body 230 forming the receiving space 231 with a partition therebetween, and the receiving space 231 and the distribution space are formed. (233) allows the mixed adhesive flowing into the nozzle 220 through one or more communication holes 237 formed in the partition to be shared.

That is, when the mixed adhesive is supplied to the receiving space 231 through the open lower part of the static mixer pipe 211, the mixed adhesive accommodated in the receiving space 231 is distributed to the distribution space through the communication hole 237. 233) and is discharged so that it can be applied to the vehicle body.

Here, the mixed adhesive discharged to the outside is implemented through a distribution plate 250 that has a predetermined width and is formed in the shape of a plate so that it can be applied evenly, and a fishbone that does not have an inclination is located at the bottom of the distribution plate 250. ) is discharged to be evenly spread over the car body through a plurality of distribution holes 251 in the shape (see Figure 6).

At this time, the distribution plate 250 is fastened so that the upper part of each distribution hole 251 communicates with the distribution space 233, so that the mixed adhesive flowing into the distribution space 233 is connected to the plurality of distribution holes 251. It is preferable that the mixed adhesive discharged through the distribution hole 251 in this process is discharged under the influence of the discharge pressure of the solenoid valve 120 provided as a pair described above (Figure 5).

In addition, on the outer surface of the nozzle 220, the mixed adhesive flowing into the distribution space 233 is discharged only through the plurality of distribution holes 251, so that the inflow of external foreign substances, etc. into the distribution space 233 can be prevented. The cover 240 is fastened by a fastening means (for example, a bolt), and for this purpose, a plurality of fastening holes 239 are formed in the cover 240 and the partition wall to face each other.

Of course, a through hole through which a fastening means passes is formed on the outer surface of the distribution plate 250 disposed between the nozzle 220 and the cover 240 at a position opposite to the fastening hole 239, so that the fastening formed on the cover 240 A structure in which the fastening means entering through the hole 239 penetrates the distribution plate 250 and then fastens with another fastening hole 239 existing in the partition wall can be satisfied.

Meanwhile, in the present invention, the fastening hole 239 present in the distribution space 233 is connected to the partition wall to have the same height as the depth of the distribution space 233, as shown in FIG. 6, and is connected to the distribution plate 250. It can be formed on a protruding part so that it can be interviewed.

As a result, the mixed adhesive flowing into the distribution space 233 can be prevented from flowing into the fastening hole 239, thereby providing convenience in separating and fastening the fastening means.

In addition, as shown, the protruding fastening hole 239 is molded into a circular or triangular shape so that the mixed adhesive flowing into the distribution space 233 through the communication hole 237 is in the lower part of the distribution plate 250. This ensures that the structure is uniformly supplied to each formed distribution hole 251.

In addition, as shown, the suction cylinder 260 is provided as a pair to be inserted and installed through a pair of coupling holes 235 formed on both sides of the upper outer surface of the receiving body 230 with respect to the nozzle pipe 210. .

The suction cylinder 260, which is controlled individually or collectively by the control unit, is inserted into the receiving space 231, and through forced suction, not only the mixed adhesive remaining in the receiving space 231 but also the nozzle pipe 210 or The mixed adhesive remaining in the distribution space 233 is allowed to be discharged to the outside.

Therefore, through forced suction of the mixed adhesive remaining in the nozzle member 200 after the application process is completed, a portion of the mixed adhesive is stuck to the distribution hole 251 or the drop phenomenon occurs, causing unwanted mixed adhesive to be deposited on the applied layer. This prevents it from falling.

Meanwhile, the suction cylinder 260 in the present invention is controlled by a control unit so that it can operate in a stopped state of the solenoid valve 120, and the forcibly absorbed adsorption adhesive is used in the static mixer pipe 211 as necessary. It is also possible to make it reusable by connecting a pipe so that it can flow into the system.

As described above, the applicator 1 according to the present invention is different from the conventional one by using a pair of suction cylinders 260 provided in the receiving body 230 to apply the nozzle member 200 at the time the application process is completed. By forcibly sucking the remaining mixed adhesive to the outside, the effect of evenly applying the mixed adhesive to the car body is expected.

In addition, unlike in the past, a mixed adhesive mixed with different adhesive compositions is not produced in advance through a pre-treatment process, but a mixed adhesive mixed with different adhesive compositions supplied in equal amounts through the static mixer pipe 211. Through a structure that can be obtained and supplied to the nozzle member 200, an effect that facilitates mass production is expected.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those skilled in the art can make various modifications and variations from this description.
