The driving end of the Y-axis driven linear module 21 is equipped with a transfer movable frame 22. The upper end of the transfer movable frame 22 is equipped with a fuse carrier plate 23. The fuse carrier plate 23 is provided with a plurality of positioning holes distributed in an array.

[0032] Further, such as Figures 1 to 3 As shown, the frame 1 is equipped with a gantry 4 located above the transfer workbench 2, the upper end of the gantry 4 is equipped with an X-axis driven linear module 5 that moves horizontally along the left and right directions, the driving end of the X-axis driven linear module 5 is equipped with a Z-axis driven linear module 6 that moves vertically, the driving end of the Z-axis driven linear module 6 is equipped with a lifting movable frame 7, and the lifting movable frame 7 is equipped with an automatic dispensing component 8.

[0033] Furthermore, if Figures 3 to 5 As shown, the automatic dispensing component 8 includes a dispensing syringe 81, which includes a vertically arranged injection cylinder 811, a piston push rod 812 telescopically and slidably installed inside the injection cylinder 811, and a dispensing nozzle 813 installed at the lower end of the injection cylinder 811.

[0034] It should be pointed out that if Figure 1 and Figure 2 As shown, the automatic filling machine for fuse potting glue also includes a man-machine control box 9, and the constant temperature stirrer 3, X-axis drive linear module 5, Y-axis drive linear module 21, Z-axis drive linear module 6 and pull-out drive mechanism 82 are electrically connected to the man-machine control box 9 respectively; when working, the man-machine control box 9 controls the actions of the constant temperature stirrer 3, X-axis drive linear module 5, Y-axis drive linear module 21, Z-axis drive linear module 6 and pull-out drive mechanism 82 respectively.

[0035] For the constant temperature stirrer 3 of the first embodiment of the present invention, it can perform constant temperature stirring on the material cup 31 containing the quartz sand mixed glue. While ensuring the constant temperature of the quartz sand mixed glue, it can also effectively prevent the quartz sand in the quartz sand mixed glue from settling, thereby ensuring that the quartz sand mixed glue always remains in a uniformly mixed state.

[0036] For the fuse carrier 23 of the first embodiment, before the fuse is sealed with quartz sand mixed with glue, the staff puts the fuse into the positioning hole of the fuse carrier 23. The positioning hole adopts a contour design and its contour shape is consistent with the contour shape of the fuse, thereby ensuring that the fuse can be accurately positioned and placed in the positioning hole. In addition, the fuse carrier 23 of the first embodiment can load multiple fuses at one time.

[0037] The following describes the automatic filling machine for fuse potting glue of the first embodiment in combination with the specific action process, specifically:

[0038] Step 1: The staff pours the quartz sand mixed with glue into the material cup 31 of the constant temperature mixer 3, and places the fuse carrier 23 loaded with the fuse on the upper end of the transfer movable frame 22, wherein the transfer movable frame 22 can position the fuse carrier 23;

[0039] Step 2, the Y-axis driving linear module 21 drives the transfer movable frame 22 to move and move the fuse to be glued and potted to the glued and potted position;

[0040] Step 3, after the fuse of the fuse carrier 23 moves to the glue dispensing and potting position, the X-axis driving linear module 5 drives the automatic glue dispensing component 8 to move above the material cup 31, and then the Z-axis driving linear module 6 drives the automatic glue dispensing component 8 to move downward and insert the glue dispensing nozzle 813 into the quartz sand mixed glue in the material cup 31, and then the pull-pull driving mechanism 82 is activated and the piston push rod 812 is moved upward, so that the glue dispensing syringe 81 extracts the quartz sand mixed glue;

[0041] Step 4, after the glue dispensing syringe 81 extracts the quartz sand mixed glue, the Z-axis drives the linear module 6 to drive the automatic glue dispensing assembly 8 to move upward and reset, and then the X-axis drives the linear module 5 to drive the automatic glue dispensing assembly 8 to move horizontally and move the glue dispensing syringe 81 that extracts the quartz sand mixed glue to just above the fuse;

[0042] Step 5, after the dispensing syringe 81 with quartz sand mixed with glue is moved to the top of the fuse, the Z-axis driving linear module 6 drives the automatic dispensing assembly 8 to move down to the dispensing filling height position, and then the pulling driving mechanism 82 pushes the piston push rod 812 downward, so that the dispensing syringe 81 injects the quartz sand mixed with glue into the fuse, and then the Z-axis driving linear module 6 and the X-axis driving linear module 5 drive the automatic dispensing assembly 8 to reset to the initial position;

[0043] Step 6, the Y-axis drive linear module 21 cooperates with the X-axis drive linear module 5 and completes the glue dispensing and potting operations of the array-distributed fuses in turn; after all the fuses on the fuse carrier 23 complete the glue dispensing and potting operations, the staff removes the fuse carrier 23 from the transfer movable rack 22, and then places the fuse carrier 23 loaded with fuses that have not been glued and potted on the transfer movable rack 22, and completes the subsequent fuse glue dispensing and potting operations according to the above steps 1-5.

[0044] Based on the above, it can be seen that through the above structural design, the automatic fuse potting glue filling machine of the first embodiment can automatically and efficiently perform quartz sand mixed glue potting operations on fuses, and has the advantages of novel structural design and high degree of automation.
