Description

Technical Field

[0001] The invention relates to the technical field of relay production, and in particular to a glue dispensing device for relay production. Background Art

[0002] A relay is a commonly used electrical control device. It is an automatic switch that uses a small current to control the operation of a large current. In automated production scenarios such as high humidity, dust, and high vibration, the relays used in such scenarios need to be glued during production to ensure their performance and reliability. The glue treatment of the relay is mainly for the side seams between the relay housing and the base plate, and the side seams between the relay pins and the base plate. After glue dispensing, the inside of the relay can be sealed, thereby improving its reliability and life.

[0003] The glue dispensing machine currently used in relay production usually combines a glue dispensing valve and a glue dispensing needle. By supplying glue with a certain pressure into the needle and moving the needle along the glue dispensing track, the glue dispensing process on the edge seam of the relay is realized. Although this glue dispensing method can complete the automatic glue dispensing process, the glue can only fall on the surface of the relay and enter the edge seam of the relay through the natural flow of the glue. In actual production, there are often leaks in the glue filling, resulting in poor sealing of the relay, and the glue dispensing yield needs to be improved; in addition, the existing glue dispensing machine only uses a glue dispensing valve to control the glue supply. After the glue dispensing valve is closed, the remaining glue in the needle is prone to dripping, resulting in a waste of glue.

[0036] The bottom surfaces of the first sealing plate 732, the second sealing plate 733 and the pin sleeve 731 are all provided with sealing gaskets, and the setting of the sealing gaskets can make the glue injection head 7 and the surface of the relay 8 pressed and sealed to avoid overflow of glue during the glue injection process; the first glue supply port 725 and the glue supply channel 734 are both connected to the main glue supply port 76, and the glue dispensing valve outlet is connected to the main glue supply port 76, and the main glue supply port 76 supplies glue to the first glue supply port 725 and the glue supply channel 734.

[0037] The glue injection head 7 also includes a synchronous drive component 74, which is used to change the sealing state of the pin injection component 73 on the side of the relay 8 pin according to the state of the edge seam glue injection component 72, so as to facilitate the pin of the relay 8 to flexibly enter and exit the glue injection head 7. A shell 75 is installed on the bottom plate 71, and a glue supply main pipe 76 is provided on the shell 75; the synchronous drive component 74 includes a drive frame 741, a first push block 742 and a second push block 743. The drive frame 741 is arranged on the periphery of the pin sleeve 731, and the first push block 742 and the second push block 743 are installed on the corresponding sides of the drive frame 741, and are respectively Used to push the first sealing plate 732 and the second sealing plate 733; a total driving frame 744 is also provided in the shell 75, and the total driving frame 744 is used to fix all the driving frames 741 in connection, and the total driving frame 744 is fixedly connected to the inner sealing frame 723; in the process that the injection head 7 contacts and presses down the relay 8, the inner sealing frame 723 will move upward relative to the guide frame 721, and the synchronous driving component 74 utilizes this movement process to drive the first sealing plate 732 and the second sealing plate 733 to press and seal the sides of the relay 8 pins to form a glue injection space, and after the glue injection is completed, it is convenient for the relay 8 pins to detach from the injection head 7.

[0038] The longitudinal linear module 21, the transverse linear module 4, the vertical linear module 5, and the air pump and the dispensing valve used for glue supply in the present invention are all made of existing technology components, and the models of the relevant components are as follows: Part Name model Manufacturer Linear guides HGR15 THK Ball Screw BNFN1204 HIWIN Stepper Motor 57HS09 Oriental Motor Motion control card PCI-1245U Advantech Stepper Motor Driver DM542 Leadshine Dispensing valve DV10 Fisnar air pump VBA40A-04 Dongguan Weisute Automation Equipment Co., Ltd. The working process of the present invention is as follows: When dispensing processing is required, first place the relay 8 upside down in the groove of the supporting plate 22 to achieve positioning of the relay 8, start the equipment, the longitudinal linear module 21 drives the supporting plate 22 to move, the transverse linear module 4 drives the glue injection head 7 on the mounting frame 6 to move, so that the glue injection head 7 is located directly above the corresponding relay 8, and the vertical linear module 5 drives the glue injection head 7 to move downward, so that the pin of the relay 8 enters the pin sleeve 731.

[0039] When the outer sealing frame 722 and the inner sealing frame 723 are in contact with the surface of the relay 8, the mounting frame 6 drives the glue injection head 7 to continue to move downward, so that the outer sealing frame 722 and the inner sealing frame 723 slide into the guide frame 721 and are pressed against the surface of the relay 8 under the action of the spring until the first corresponding port 726 on the first sealing plate 732 coincides with the first glue supply port 725 on the guide frame 721.

[0040] During the movement of the inner sealing frame 723, the inner sealing frame 723 drives the total driving frame 744 to move synchronously, and the total driving frame 744 drives all the driving frames 741 to move upward, so that the first push block 742 and the second push block 743 squeeze the corresponding first sealing plate 732 and the second sealing plate 733, and the first sealing plate 732 and the second sealing plate 733 extend out and fit on the surrounding surfaces of the pins of the relay 8 to form a glue injection space. At this time, the outlet of the glue supply channel 734 in the second sealing plate 733 is in an open state.

[0041] The glue dispensing valve is started to supply glue to the glue supply main pipe port 76, and the glue supply main pipe port 76 supplies glue into the corresponding area and makes the glue have a certain pressure to fully fill the side seams of the relay 8, thereby realizing the rapid integrated glue dispensing processing of the relay 8; after the processing is completed, the vertical linear module 5 drives the glue injection head 7 to move upward, the glue injection head 7 is separated from the relay 8, and the inner sealing frame 723 is quickly reset under the action of the spring, so that the first corresponding port 726 and the first glue supply port 725 are staggered, and the second sealing plate 733 is reset to quickly block the outlet of the glue supply channel 734, thereby avoiding leakage of excess glue in the pipeline.
