Technology Field

[0001] The present invention relates to an adhesive application device, and more specifically, to an adhesive application device for an automotive connection terminal for automatically applying adhesive to a connection terminal applied to an automobile. Background Technology

[0002] Generally, a connection terminal is a device in which cables are connected at both ends to transmit power or data from one direction to the other; it is also referred to as a connector and is applied in various industrial fields.

[0003] Among these connection terminals, automotive connection terminals applied to automobiles are positioned between separated cables within the vehicle and function to connect the said separated cables. For example, they are applied to carburetor actuators, etc.

[0004] When such a connection terminal is applied in a place requiring sealing, the connection terminal is made of a metal material such as stainless steel, and the connection terminal assembly, such as a plug to which the connection terminal is joined, is made of a synthetic resin material such as plastic.

[0005] Therefore, due to the different properties of the connection terminal and the connection terminal assembly, the seal is broken at the part where the connection terminal is joined. To prevent this, a sealable adhesive is applied to the connection terminal, and then the connection terminal assembly is joined to create a primary seal. Additionally, molding is performed on the connection terminal assembly to create a secondary seal.

[0006] However, conventionally, as a worker applies the adhesive to a brush or similar tool and then applies it to the connection terminal using the brush coated with the adhesive, not only was the adhesive application process time-consuming, but there was also a problem of inconsistent product quality due to variations in the amount and location of the adhesive applied by each worker.

[0007] In addition, conventionally, there was a problem where workers suffered injuries, such as headaches or even collapsed, due to the odor emitted when the adhesive was exposed to the air during application.

It should be noted that the same components in the drawings are indicated by the same reference numerals wherever possible.

[0018] Referring to FIG. 1, the present invention is provided as a device for automatically applying adhesive to a connection terminal applied to an automobile.

[0019] Specifically, the adhesive application device for an automobile connection terminal of the present invention comprises an application unit (200) for applying adhesive to a connection terminal and a vacuum unit (220) installed at the bottom of the application unit (200) for exhausting harmful gases generated during the adhesive application process.

[0020] Meanwhile, a distribution plate (210) is provided in part of the coating unit (200), and the coating unit (200) and the vacuum unit (220) are provided in a structure arranged in upper and lower two stages, and a moving wheel is mounted on the lower part to ensure mobility.

[0021] Referring to FIGS. 3 and 8, the coating unit (200) is provided with a moving part so that a coating head part (28A) for automatic adhesive coating can move. Specifically, the moving part is composed of a pair of X-axis moving parts (22) arranged longitudinally on the frame (21), a Y-axis moving part (23) arranged orthogonally to the X-axis moving part (22), and a Z-axis moving part (28) connected to the Y-axis moving part (23) and moving in the height direction.

[0022] Meanwhile, an application head part (28A) that automatically applies adhesive is mounted on the end of the Z-axis moving part (28).

[0023] Next, the frame (21) is provided with a jig mounting frame (31) on which a plurality of jig parts (24, 25) are each mounted. Here, the jig mounting frame (31) is each rotated by a rotation drive unit (26, 27).

[0024] Referring to FIG. 4, a plurality of jig parts (24, 25) are each placed in a jig mounting frame (26, 27), a plurality of individual terminals (D) are arranged in a row, and a plurality of coating guide grooves (25e) are formed in each. That is, the jig parts (24, 25) are arranged such that the individual terminals (D) form a plurality of rows in a row between an upper plate and a lower plate having the same shape. In addition, these individual terminals (D) are fixed in a state where they are arranged in a row so that the area to be coated is exposed within each coating guide groove (25e).

[0025] Accordingly, the adhesive is applied to the individual terminals (D) as the application head (28A) moves back and forth along each application guide groove (25e). That is, as shown in FIG. 6, the adhesive (P) is applied to the central area of ​​the body of the individual terminal (D), and a plurality of development terminals (D) are connected to each other by a connecting member to form a connecting terminal for automobiles (see (c) in FIG. 6).

[0026] Meanwhile, as shown in Fig. 7, multiple individual terminals can be transported in a state where they are arranged in a row on an individual terminal tray (100).

[0027] The adhesive application device for a connecting terminal for an automobile according to the present invention configured as described above can apply adhesive (P) to the front surface of individual terminals (D) by the application head part (28A) reciprocatingly moving along the application guide groove (25e) of the jig part (24 or 25) of any one of the plurality of jig parts (24, 25) by means of the X-axis moving part (22), the Y-axis moving part (23), and the Z-axis moving part (28).

[0028] Meanwhile, when the application of adhesive (P) to the front surface of the individual terminal (D) is completed, the upper and lower surfaces of the jig sections (24, 25) can be inverted by the rotary drive unit (26, 27), and the application process of adhesive (P) to the lower surfaces of the individual terminals (D) can be performed. At this time, the application process can be performed while the application head unit (28A) reciprocates between the multiple jig sections (24, 25). That is, when the application process on one side of the jig section (24) is completed, the rotary drive unit (26) rotates to invert it, and the application head unit (28A) moves to the other jig section (25) to perform the application process on the rear surface (i.e., the application process while reciprocating between both jig sections), thereby improving process efficiency.

[0029] Meanwhile, referring to FIG. 2, the vacuum unit (220) is composed of a moving part (223) for moving to the lower side of a plurality of jig parts (24, 25), and an intake plate (221) that moves by the moving part (223) and is connected to an intake pipe (224) to suck in fume gas containing harmful gases generated during the coating process at the lower part of the jig mounting frame (31). Here, a filter member (222) is mounted on the intake plate (221) to remove foreign substances from the sucked fume gas. In addition, a vacuum pump (225) is connected to the intake pipe (224) to provide vacuum pressure to suck in the fume gas.

[0030] Referring to FIGS. 9 and 10, the jig mounting frame (32) comprises a rotating shaft portion (26a) connected to a rotating drive unit (26), a bearing seat portion (27b) positioned opposite the rotating shaft portion (26a) and mounted on an X-axis moving unit (22), a jig sensing element (25S) that detects when a jig portion (24) is mounted on the jig mounting frame (32), and a plurality of pressure clamping elements (25P) that press and fix the side of the jig portion (24) when the jig sensing element (25S) detects the mounting of the jig portion (24). That is, a fixing groove is formed on one side of the jig portion (24, 25), and by pressing the pressure clamping element (25P) into this fixing groove, the movement of the jig portion (24, 25) in the jig mounting frame (32) can be prevented.

[0031] According to the present invention, contaminated air generated during the adhesive application process can be discharged to the outside through a vacuum unit (220), thereby protecting the worker from harmful gases generated during the adhesive application process.

[0032] In addition, production efficiency can be significantly improved by automatically switching the upper and lower surfaces of each of the multiple jig parts (24, 25) and efficiently applying adhesive to multiple individual connection terminals (D) through the automatic application unit (200).

[0033] Although the present invention has been illustrated and described with respect to specific embodiments, the present invention is not limited to the embodiments described above, and those skilled in the art may make various modifications without departing from the gist of the technical concept of the present invention as described in the following claims.
